The power sector plays a crucial role in economic growth in a developing country like India. India’s ever-increasing demand for electricity is an indicator of growing market size and rising ambitions. Hence, government policies in this field have a large-scale impact ranging from a village household to a global conglomerate in India.

Union finance minister Nirmala Sitharaman's Union Budget 2022-23 should focus more on accelerating initiatives and targeted policy changes to achieve the goal of 500 gigawatt renewable energy by 2030. A massive push for public mobility infrastructure, power distribution infrastructure and renewable capacity addition is required in the Budget, considering India's commitment to reduce carbon emissions.

Industry demands more provisions are required to achieve the targets. Capital expenditure toward smart and clean infrastructure - including railways, power transmission and power grid upgradation - should be enhanced to create a multiplier effect in investments and create new employment opportunities to uplift the economy.

Although India is making remarkable progress in meeting its ambitious renewable energy targets, the public e-mobility space leaves a lot of scope for charging infrastructure, as the country needs to add 400,000 stations by 2026 to meet India’s 2030 EV target. That is, adding more than 200 charging stations a day.

This issue of Electrical Mirror is also touched upon important topics like Union Budget- 2022, testing & measuring, Power factor correction, Transformer, Stamping & Lamination, Automation and Hydro power. Hope you’ll enjoy reading this issue as always.

Happy Reading!!!

Budget Quotes

Quotes on budget Mr. N Venu, MD & CEO, India & South Asia Hitachi Energy “India delivered a pro-growth budget with a significant push to capital expenditure to boost the supply side and attract private investment. The government appears to have had its ears to the ground and covered a vast gamut of sectors in its four priority areas -- PM Gati Shakti, Inclusive Development, Climate Action, and Energy Transition. Intentions have been clear – steer India toward sustainable development with a strong focus on financial support to MSMEs and expansion of emerging sectors such as solar power, EV infrastructure, railways, data centers.

Additional allocation of INR 19500cr for PLI scheme, development of new-gen trains over the next three years, INR 1400cr allocation for hydro and solar projects in FY23, rationalization of custom duties on select capital goods, wider coverage of single-window clearance for green projects will pave the way toward clean energy transition.

Clear emphasis on technology and digitalization with due consideration to upskilling the youth and R&D to build back better are a big positive.

While some important elements such as a new SEZ legislation, funding schemes for new metro rail systems and cleantech, urban planning to promote sustainable living, battery swapping policy appear to work in progress. the government has laid the blueprint for growth over the coming two-three decades.

Unambiguous intent on achieving its COP26 ambitions through key proposals such as urban planning, energy efficiency, increased budget for PLI, distributed grids for remote villages, and finance to enable these through new climate finance services and categorizing grid-scale BESS as harmonized infra. Focus on standardized and efficient mass transport metro & rail will help normalize costs. The battery swapping and interoperability proposals for EVs are a way of triggering adoption, which will then create enough demand for technology evolution. MSME ratings will help calibrate the Indian supply chain to world-class.

The climate-responsive budget also keeps consumers at the center - DISCOM options, skilling & employability, focus on R&D.”

EM

Mr. Bharat Bhut cofounder & director, Goldi Solar “Budget 2022 has given indigenous manufacturers several reasons to cheer. Implementing 40% BCD on solar modules and the additional allocation of Rs 19,500 crore for PLI for solar PV module manufacturing will ensure the growth of the entire domestic manufacturing ecosystem. The application requirements should be tweaked to ensure that MSMEs also benefit from the scheme. All of these measures will result in a more robust domestic module supply, increased confidence in Indian solar modules and reduced reliance on imports while furthering our aim to achieve an Atmanirbhar Bharat. As a next step, the government needs to define measures to be taken in the R&D space to foster innovation and help companies stay ahead of the technology curve.” EM

Mr. Shohab Rais, Chief Operating Officer Indian Chemical Business, Tata Chemicals, “The government this year is very clear on its move towards enabling energy transition through provisions for boosting domestic manufacturing of solar power equipment and batteries, in line with India's larger global commitment of tackling climate change. The government’s major allocation is towards focusing on the growth of grid-connected energy storage and supporting incentives for green bonds. The budget is very well thought through in terms of enhancing domestic value addition by reducing customs duty on certain critical chemicals namely methanol, acetic acid, and heavy feedstocks for petroleum refining, while duty is being raised on sodium cyanide for which adequate domestic capacity exists. Also, PM Gatishakti and specifically, focus on waterways, ports, roads, and railways, coupled with the proposed unified logistics’ interface platform will help improve supply chain efficiency and reduce logistics’ costs across sectors”.

Mr. Dinesh Aggarwal Joint Managing Director Panasonic Life Solutions India After the 2nd wave affected the retail sector in the first quarter, the recovery for us was much faster. Real estate developers had ensured functioning labour to avoid shutting down of construction and restraining a mass exodus. As global economies were getting affected, India was still strong and there was a bounce back in the market despite the underlying situation. However, with the unprecedented increase in the price of metals, plastic raw material, paper and transportation, the overall growth was hit. This was compounded by the disruption of supplies especially for electronic components due to container shortage and disruption of shipping lines. This has already reflected in the form of inflation across all product categories that we cover, essentials and discretionary items.

Amidst the ongoing 3rd wave of the pandemic, the upcoming union budget 2022-23 is expected to play a pivotal role in countering inflation and galvanizing demand, especially for private consumption. The long-term intent of the Government towards the infrastructure sector with the committed investments and special focus on manufacturing will get further highlighted and accelerated through the Production Linked Incentive (PLI) schemes. This is a significant step towards making India a global manufacturing hub. There is thus a need for incentivizing modernization and innovation so that the industry across the infrastructure, manufacturing and agricultural sectors will have the scope to be more competitive and gain scales of their economy. This will further align with the objectives of Atmanirbhar Bharat.

There is an expectancy of the Budget to cover private public partnership, which will encourage the use of the existing physical infrastructure of the Government across India and accelerate skills as well. This can be in the form of income tax benefit or specific grants by the Government.

Some areas where the continuation of work is expected includes the optimization of GST rates; FDI inflow in all sectors including the construction sector; boosting exports and prompting ‘made in India’ globally; encouraging affordable housing and supporting real estate developers through priority lending and liquidity boosting measures. These efforts will help in stimulating our economy.

With India committed to reduction in carbon footprint, reiterated by honorable Prime Minister in opening address at the WEF, Davos this year; a further impetus to manufacturing of electric vehicles and establishment of charging infrastructure is expected. This maybe supported with a policy announcement on generation and distribution of renewable energy across India overcoming state-wise barriers.

We are optimistic about the Union Budget 2022-23, which we believe will support a consistent GDP growth of over 8%, despite the challenge of pandemic. EM

Mr. Gautam Seth Joint Managing Director HPL Electric & Power Ltd. It is a growth oriented and forward looking Budget. The ambitious goal of 280 GW of installed solar capacity by 2030 has been set with an additional allocation of 19,500 crores for manufacturing solar PV modules, in the power and energy sector I believe the Budget 22 will increase the growth and will help in ramping up domestic capacity.

This is a highly sustainable and green energy choice. The government’s concern towards standardising the domestic manufacturing of electronic smart meters, wearable devices and hearable devices is a boon for India to become an electrical manufacturing hub. The proposal of surety bonds as a substitute for bank guarantee is highly welcomed.

Furthermore, Rs. 48,000 crores are allocated for 80 lakh houses to be completed both in rural and urban areas which is a huge step towards the upliftment of the society. EM

ABB India turns its Nelamangala Campus

‘water positive’

Press Release

• Total annual rainwater harvesting potential of more than 200 million liters • The campus has achieved close to 85% water recyclability • Water positivity index is 1.24

14

ABB India today announced that its Nelamangala unit has received a ‘Water Positive’ certification from The Energy and Resources Institute (TERI). In place of simply replacing the amount of water taken from the environment, the unit implemented an Innovative 6R approach towards ‘Water Positivity’ to replenish more water than it consumes at the location.

The unique 6R approach includes initiatives such as rainwater use and recharge, reduction in the use of freshwater, water recycling, and real-time monitoring of water consumption, recharge, and saving.

The Nelamangala unit currently has 17 rainwater recharge wells, 2 recharge ponds along with 5 cross wave technology-based recharge tanks. ABB products such as water flow meters were installed in the rainwater recharge system to capture real-time data.

To reduce consumption of water, ABB India installed water-efficient fixtures, restricted the use of turf in the landscape area, and planted drought-tolerant plants in 81 percent of the landscape area. The unit has provisions of rainwater tanks for rooftop runoff along with TERI-approved filtration to get suitable water for a variety of end-uses.

The campus has achieved close to 85 percent of water recyclability with the help of efficient Sewage Treatment Plant (STP) and recycling the treated wastewater for use in gardening and washrooms.

The water positivity index for Nelamangala plant is 1.24, which demonstrates our contribution towards replenishing much greater quantity of water for the environment than withdrawals for our operation.

The index also shows our enhanced dependency on secondary water sources such as treated wastewater, rainwater, etc. and lesser dependency on groundwater sources for our operation.

“At ABB, ‘sustainability in practice’ is at the core of everything we do.

It is a key part of our company’s purpose and of the value that we create for our customers, employees, and all our stakeholders. Our Nelamangala unit turning ‘Water Positive’ is a step towards continued resource conservation, in line with our 2030 global sustainability commitments. We are committed to implementing various other similar environment-friendly measures across our ABB India locations to bring about a sustainable change,” said Sanjeev Sharma, Country Head and Managing Director, ABB India.

“In times of a severe water crisis in India, I am pleased to acknowledge that TERI has awarded India’s first water positivity certificate to ABB India, for one of their six factories in the country. I look forward to witnessing more partnerships in the sector and development of innovative solutions to manage and monitor natural resources on

Becoming a Net Zero Company Means More Profit - Here's How!

Press Release

Sustainability refers to the business programs, products, and practices built around environmental and social considerations that are often seen as a luxury investment. Sustainability initiatives can help to create profits and business opportunities.

This sudden and rapid transition to achieve net-zero carbon emission is such a formidable task that companies often assume, it is impossible to achieve while maintaining their profit margins.

The companies and startups need to focus on short-term solutions such as they offload emissions onto others by divesting high-carbon emitting businesses. It helps different organizations to start off by focusing on here-and-now emissions reductions.

The one thing that helps to achieve this mission is to shift to solar energy and switching to renewable-sourced electricity is a good way to reduce carbon dioxide emissions. We need to redesign the business models to reduce emissions in such a way that it can be achievable yet profitable.

The idea of corporate sustainability has become part of the mainstream business discourse in the past 20 years. Recently, a report by the UN Global Compact suggests that 84 percent of the 1,000 global CEOs surveyed agreed that businesses should lead efforts to define and deliver new goals on global priority issues. Achieving net-zero sustainability is usually based on the corporate agenda, there are often problems with execution, even in the most committed companies. To deliver real strategic opportunities, industry players should consider applying four organizational practices. It is attached to performance management but they are not often used to address sustainability challenges.

Reducing Carbon emissions successfully and achieving a net-zero mission, companies have to take action on various scopes: Find out and tackle the root causes - The places where the big emissions happen are often not the most effective places for action. We need to build a mechanism to track emissions to find their root causes, either within their own business or along the value chain. Reduces emissions through fleet electrification and routing optimization. It helps to get better information and control to the people receiving deliveries, so that they can anticipate and redirect a delivery, reducing the number of delivery attempts. Tech startups and companies in this field need to measure power efficiency down to the code level in their AI and Cloud deployments and work with chip manufacturers to reduce energy consumption in the use of their products.

Not defund high-carbon business - Investors are often tempted to increase their portfolio of low-carbon activities by simply rebalancing their allocation of capital. To incentivize reduction is to invest in activities that currently cause high carbon emissions is the more effective approach when it comes to while setting out a clear and urgent pathway to change. Net-Zero carbon emissions mission requires more than $100 trillion investment the transition will require, 70-80 percent needs to go into some of the hardest-to-abate sectors. It requires a sudden shift from demanding divestment to demanding a managed transition of high-carbon businesses.

that they will transition with their clients, and that transition will require capital. It helps to develop the credibility of these initiatives that the path of change delivers the pace and scale required by science.

Big giant industry players and startups fail to recognize that sustainable production can be less expensive. We need to change the lowering costs, taking a leap of faith. They need to make more early investments in more-costly materials and methods that will guide them to greater savings down the road. They also need to focus not on reducing the cost of each part but on increasing the efficiency of the system as a whole.

Take the Low key technology path, unlike western companies, which often try to mitigate the environmental damage done by their operations through costly retrofits or by underwriting the development of breakthrough technologies, many companies in emerging markets start small. Businesses can expand conservation efforts to other parts of their operations with low-cost moves reap larger and larger returns. Savings contribute to funding purchases of expensive technologies and R&D initiatives that many Western companies might have started with.

Focus on taking a wider View - Impressive as the cost efficiencies are, more intriguing is the growth that companies in emerging markets have gained by extending their sustainability efforts to the operations of their customers. Boosting customers’ buying power requires building unique business models and, in the process, creating interdependencies that are difficult for competitors to copy.

Industry leaders should make a change to their business models to answer to major discontinuities, such as higher naturalresource prices or changes in demand, that create material risks to the business—or opportunities. Initial investments are more expensive methods of sustainable operation that lead to dramatically lower costs and higher yields. We are required to take a bootstrap approach to conservation: They should start with small changes to their processes that generate substantial cost savings, which they can fund advanced technologies that make production even more efficient. The crucial sustainability efforts are taken by industry leaders to the operations of the customers and suppliers, in the process devising new business models that competitors find hard to emulate.

To reduce a company’s carbon footprint, the best ways will not always lead to net-zero. To grow furthermore and achieve the aim of a net-zero carbon emission task, companies need to engineer emissions out of their entire business system, including their supply chain and customers’ use of their products. It also offers a process to scope out product innovations that use fewer resources or that meet specific social needs. To increase profits and reduce the cost of production, companies can follow redesigning products and services. The focus on the following sustainability can also lead to opportunities for process innovations. Due to the cross-functional nature, sustainability brings different divisions together and provides a common motivation. EM

The new age T&M equipment needs to identify, isolate and analyze Accurate testing and measurement is critical in electronic systems design and manufacturing to ensure product quality. Test and measurement (T&M) systems play an essential role in ratifying the performance of a wide range of electronic products.

Increased product complexity has spurred the demand for precision testing at every stage of the product’s life cycle, right from design and development to production testing, pre- and post-market testing, as well as support. Thus, the growth of the test and measurement industry goes hand in hand with the growth of the electronics industry in the country.

The budget is keenly followed not just for the immediate fiscal measures but also for the policy priorities of the government. At the crossroads, where the overall economy and the power sector stands, the pronouncements of the budget will be keenly followed. In the current fiscal, overall economic growth has dipped sharply and, in

all likelihood, GDP growth will be under 5 per cent. This has been one of the key contributing factors for the stagnation of power demand.

Simultaneously, the supply pipeline has been quite full, resulting in falling load factors of thermal power plant s and curtailment of renewable energy.

Given the ambitious plans of the government to double the renewable energy capacity to 175 GW by 2022 from 86 GW at present, all investors will be nervously watching for moves that will perk up the economy and, consequently, electricity demand.

Even as capacity in the power sector has expanded significantly in the past decade, this has heavily depended on equipment imports, particularly from China. As a consequence, more than 200 GW capacities has been added in the past decade at an estimated cost of 10 lakh crore but without creating commensurate jobs and competencies.

At this moment, the unemployment rates stand at a 45-year high. The government would be concerned about this and hence, I do expect the policies and fiscal measures to be focused much more on domestic job creation. The

The competitiveness of the economy also depends on the efficiency of operations in the power sector and electricity prices. The tariffs of industrial and commercial electricity are abnormally high in India rendering energy-intensive manufacturing uncompetitive. While the budget is not the platform for tariff rationalisation, there could be some reduction in duties to reduce consumer tariff, particularly in the industrial sectors. Recent news reports indicate that elimination of the coal cess of INR400 per ton of coal has caused the cost of coal-based power generation to increase significantly with an impact of more than 50 ps/kwh. Given that the coal cess has been used primarily for GST compensation to states in recent years and there is little revenue buoyancy at this time, I would be pleasantly surprised if the cess is done away with. A reduction, however, is more likely on the cards.

Finances of state-owned power distribution companies have been in the cesspool for decades. The UDAY scheme marked a serious effort to set this straight. Despite the initial promise, UDAY has not delivered the outcomes that the government desired. A new programme marking a renewed effort is on the cards. It needs to be seen how this is different from past initiatives and how it would deliver better than past attempts.

The bottom line, however, is that no amount of budgetary support and over-the-top interventions can mend the sector’s finances unless very fundamental changes are made to the way the sector is structured, operated and regulated.

associated manufacturing and installations, is a good avenue for tax breaks.

All of this though must lead to kick-starting demand and we need the right set of incentives for efficient consumption. This, in turn, would reignite the investment cycle and, eventually, lead to a higher energy/electricity off take. Hence, while the budget would always contain a range of direct measures affecting the electricity sector, the greatest emphasis has to be on scaling up manufacturing, creating new jobs in a sustainable manner and removing distortions that have prevented India from emerging as a strong manufacturing economy. Those measures would be of much greater importance than some individual steps to prop up the power sector specifically.

The core structural challenges in the distribution sector have to be dealt with through the introduction of competition and transparency.

In line with the current economic thinking of the government on increasing private sector participation, it would be worth providing incentives for franchising and privatisation for accelerated technology deployment for improving customer service and reducing losses. This could be on capex up to a certain limit per lakh of customer base.

is an emerging solar hub of the world, considering that capacity for nearly 100GW of solar power is to be added in the next five years. So solar power could become a very important market for T&M products.

Emerging trends The need for a connected and safer world, leveraging advances in the Internet of Things (IoT), machine-to-machine (M2M) interaction, autonomous driving and 5G are the new technology trends that will lead to the growth of the T&M industry worldwide and in India too.

According to the latest study by Frost & Sullivan, titled, ‘Global Electronic Test and Measurement, Forecast to 2022’, the growth will span a range of technologies and cover the entire product life cycle—from R&D to manufacturing and quality assurance.

In the next five to ten years, a lot is expected to happen, whether in the wireless technology or application areas. For example, IoT is one of the key driving factors. The proliferation of smart devices has begun to influence the design and use of T&M equipment. Each ‘smart’ product has to go through a specific set of processes to ensure its usability and functionality for the intended purpose – and behind each of these steps are the design, manufacturing and testing procedures. T&M technologies are going to evolve accordingly. There are emerging needs for embedded/portable T&M solutions, IoT test solutions with remote troubleshooting capabilities, and solutions that can support the latest interfaces and protocols.

In wireless technology, the emergence of 5G is going to

ELECTRICAL MIR ROR

|| February 2022 ||

change the technology landscape. The greater need for interoperability and 5G are the top two emerging trends in the global T&M market. Two key features in 5G NR are especially important for the realisation of higher data rates than in LTE—the use of millimeter wave frequencies (up to 100 GHz) and support for significantly higher signal bandwidths. In particular, 5G NR supports signal bandwidths up to 100MHz for carrier frequencies below 6GHz and up to 400MHz for frequencies in the millimeter wave range.

These developments present new challenges for development engineers. Designing power amplifiers that exhibit the necessary characteristics (e.g., linearity) is not easy and may need new design approaches (e.g., digital predistortion). The circuitry needed to generate frequencies in the millimeter wave range requires well-thought out design and the careful selection of components in order to reduce the effects of phase noise introduced by mixers and multipliers. Beamforming also requires very good amplitude and phase synchronisation between antenna elements in active antenna systems.

The high frequencies intensify the challenges for T&M methods.

The short wavelengths and higher losses in circuits necessitate tight integration, making it impractical to supply connector ports for testing. At the same time, the effects of connectors and test fixtures become non-negligible, potentially affecting the validity of the measurements recorded. As a result, over-the-air (OTA) testing will play an important role.

Automation powered by M2M interaction is the new technology trend in the power sector and, hence, the

||www.electricalmirror.net||

demand for automated products is growing. Accordingly, the new technological advancements like data logging DMMs and automated power-calculating power clamp meters will experience good growth. Online transmission line monitoring systems, compact tan-delta testing machines, automatic breaker testing machines, discrete monitoring of power losses at each feeder by distribution companies, etc, are some of the key areas of application.

With respect to the user experience, touchscreen technologies are going to revolutionise the T&M environment. A combination of the right hardware with a ‘designed for touch’ user interface (UI) will enable companies to use equipment easily and efficiently. ‘Designed for touch’ UIs are crucial for creating an effective and usable touchscreen, since it is not enough to simply add a touchscreen to an existing UI. The new age T&M equipment needs to identify, isolate and analyse a system under test as quickly and efficiently as possible. Having an effective touchscreen on the instrument can reduce the time it takes to configure the system and to analyse signals. Thus, instruments with better GUIs result in ease of operation and automated testing capabilities, which increases productivity.

Faster switching power electronic devices The trend in power electronics is to push the operating frequencies higher to reduce size, weight and cost of the systems. This requires faster switching power electronic devices, such as SiC and GaN MOSFETS, and diodes. To test and characterise such devices, you need faster measurement devices like higher bandwidth oscilloscopes and power analysers.

For design and architecture stages, key factors that help select test instruments include high-frequency dynamic behaviour, static behaviour, fast inverter switching, trigger for individual waveforms and overshoot on pulses. Measurement at this stage requires mixed-signal oscilloscopes with multiple channels.

Measured parameters Dynamic behaviour of power electronics can be measured with a scopecorder (oscilloscope-cum-data acquisition recorder).

A data acquisition recorder handles a wide range of power measurements and captures high-resolution details with a 12or 16-bit ADC. A spacecorder carries out complex calculations to measure power factor, active power and harmonics using a digital signal processor.

Dynamic parameters such as switching times (Trise, Tfall, Tdelay or Trr) use high- bandwidth oscilloscopes. Static ||www.electricalmirror.net||

parameter measurements need curve tracers and parametric analysers. Static parameters include VCEon, VDS, RDSon, VF, VGE and leakage currents using curve tracers. Switching energies such as Eon, Eoff and Err are measured using high-bandwidth current probes and oscilloscopes with math functions.

Quality control measures Power analysis, conversion efficiency and harmonics are measured for efficiency validation. A power analyser measures efficiency, total harmonic distortion and power factor correction of circuits. For these, the test power analyser should be of high accuracy and high stability. It should have calibration ability that can measure highly distorted current and voltage waveforms accurately.

Online inspection and troubleshooting are important to reduce costs and downtime, and improve the efficiency of various electronic components. For online inspection, thermal imagers are useful for PCBs and SMD cards, for fault diagnosis and research purposes. This is due to their high IR resolutions of 320×240 pixels and 640×480 pixels. These can also be used for the mass production of electronic components for monitoring, processing and quality control.

T&M equipment for power electronics Nitin Shetty, chief executive officer, Convergent Technologies, says, “A galvanically-isolated solution like Tektronix TIVM Series IsoVu can resolve high-bandwidth differential signals up to 2500Vpk in the presence of large common-mode voltages.

The latest T&M technology for power electronics is 8-channel, 12-bit ADC and deep memory MSO 5 series oscilloscope.

“MSO is available with eight high-resolution channels, easy-to-use user interface and a large HD touchscreen display along with advanced IsoVu probing solutions.

as well as the power grids that deliver electric energy throughout the world. They are used in electric and hybrid vehicles and their charger stations. Motor drive controllers and even consumer product chargers use them. With this much use, small improvements in their efficiency can save huge quantities of energy.

Meanwhile, several industry consortiums around the world are focusing on improvements to today’s power electronics modules and their applications. The companies in these consortiums are concerned not only with the efficiency of the power electronics modules, but also their reliability because many of the applications require modules that must last for Classic versus advanced reliability testing The classic method of lifespan testing for a power electronics years and decades without replacement. module requires multiple cycles through various stages in The reliability challenge in power electronics Many of the applications for power electronics modules require a laboratory. Typically, the IGBT module is hooked up to a long life spans. For example, in wind turbines that may be power cycling source. The module may be cycled through located out in the oceans, it’s impractical to replace the a few hundred or a thousand cycles. Then the module is modules. For solar arrays on satellites, it’s basically impossible dismounted from the power cycler and taken to a lab for to fix them. Electric vehicles and hybrids are expected to failure testing. If the module has not failed, the process last 15 to 20 years without major repairs. So the challenge of power cycling and failure testing is repeated. Once the is to create modules at low cost and weight that will not module is determined to have completely failed, it is taken only support the extremely high current requirements, but to a lab to determine the cause of failure. This process can also last for many years. One method is to over-engineer, involve X-ray scanning, visual inspection or even destructive the modules but this approach adds to the cost and weight. dissecting of the module.

If they are designed to meet requirements without over-engineering, how can they then be tested for expected lifespan reliability without putting them in a test environment for years, even decades? The main issues that typically affect reliability are thermal stresses and overheating. We can approach this problem in steps. The first step is to design the modules so that they will work from a heat conduction point of view. The second step is to provide a method of testing the modules for their expected lifetime.

Reliability testing in power electronics So now you have designed a module with good heat management, that is, it has significant heat flow paths from the junction to ambient. But you still don’t really know the expected lifespan. A method of accelerating the lifespan testing and understanding what exactly is going to eventually cause the modules to fail is needed.

The main issue with high power electronic modules is the thermal stresses imposed by the repeated heating and cooling as the module powers on and off during its normal operation. In today’s applications, these modules typically 42

run from 100 to 1,500 amps with life expectancy of tens of thousands up to millions of power cycles. These thermal stresses and overheating can cause any number of failures.

The various layers of the substrate can separate and, because air is a poorer heat conductor than the solid material, the well-designed heat path will fail and the die will overheat.

The same thing can happen if the actual substrate material forms stress cracks. A power electronics module has multiple wire bonds connecting to the die to carry the heavy current loads. These wire bonds can eventually crack because of the thermal stresses or can detach because of solder failure.

There are several issues with this classic method of reliability testing. First, it’s a long process. The repeated mounting, power cycling, dismounting and failure testing is time-consuming, especially if the number of cycles to failure is high. Second, the cycle count to failure start may be indeterminate. Only after the module has completely failed could it be determined to have failed in the lab. Also, if the diagnosis shows multiple failures, it is not always possible to determine the cause and effect; that is, which failure was the initial one that caused the other failure.

New technology for reliability testing A more efficient process is needed that can determine the exact cause of the failure quickly. Such a solution needs to be able to measure electrical and thermal effects in the module during the power cycling and recognize the failure cause in real-time, without having to rely on a post-mortem diagnosis.

If the power cycling and measurement is contained in the same hardware, there is no need to dismount the modules from the power cycler and take them into the laboratory for failure analysis. Recent developments in the industry, such as the MicReD Industrial Power Tester 1500A from Mentor ||www.electricalmirror.net||

Graphics, are providing this capability.

Using the real-time structure function The structure function produced by the T3Ster provides the ability to “look” inside of the module and measure the thermal characteristics of the module’s substrate layers. This same technology can be used during the power cycling to sense substrate layer delamination and cracking.

Figure 4 shows a structure function graph with snapshots taken at this particular module’s 0; 5,000; 10,000; 15,000; 20,000 and 25,000th cycles. The blue and green lines are coincident and basically show the original “good” module’s layer characteristics. But at the 20,000th cycle, we see that the lines start to go more horizontal, indicating an increase in the resistance of the base plate solder layer. This continues to happen through the 25,000th cycle. The increase in resistance indicates a delamination of the layer, an interruption of the heat path from the die to ambient, and will probably result in overheating of the die and eventual failure.

With the classic method of testing, a failure may not have been recognized at this point. Later in the classic process, after complete module failure, multiple layers may have delaminated because of the excessive heat, but failure of the initial layer would not have been seen.

Other causes of failure diagnosed The structure function can be used effectively to sense such failures as substrate layer delamination and cracking. But other failures can occur in the modules, such as wire bond cracking or solder failure. For these types of diagnostics, the power tester has to include very sensitive methods of measuring changes in voltages and currents. For a module that contains multiple wire bonds per die, the ability to see when a single bond has failed is needed. This can be achieved by measuring small increases in the forward voltage being applied during powering up of the module. If a bond fails, ||www.electricalmirror.net||

With respect to the user experience, touchscreen technologies are going to revolutionise the T&M environment. A combination of the right hardware with a ‘designed for touch’ user interface (UI) will enable companies to use equipment easily and efficiently. ‘Designed for touch’ UIs are crucial for creating an effective and usable touchscreen, since it is not enough to simply add a touchscreen to an existing UI. The new age T&M equipment needs to identify, isolate and analyse a system under test as quickly and efficiently as possible. Having an effective touchscreen on the instrument can reduce the time it takes to configure the system and to analyse signals. Thus, instruments with better GUIs result in ease of operation and automated testing capabilities, which increases productivity. RM

will merger of both the companies (Doble- ALTANOVA) benefit for each other?

Founded in 1920, Doble Engineering Company ensures reliable, safe and secure power for all. We do this by providing comprehensive diagnostics and engineering expertise for the energy industry. Doble is part of the Utility Solutions Group of ESCO Technologies Inc. (NYSE: ESE) and serves customers around the globe. It owns brands such as Morgan Schaffer, Manta Systems and Vanguard amongst others. Its recent acquisition of Phenix Systems and Altanova are in line with the strategy to provide a range of solutions that provide the best of the technology from and to the Northern American and Rest of the World markets.

Doble opened its Indian subsidiary, Doble Engineering Pvt Ltd two decades ago to serve the local markets in the region for technical application support. Known as the librarian in the diagnostics space of the Electrical power sector and provider of rugged field test instrumentation & installations, Doble brings trust to the equation. Altanova was formed in 2017 with the amalgamation of ISA and Techimp in Italy and has its presence in India since a decade bringing trained and knowledgeable expertise and services to customers in India & the region.

The merger is more for the benefit of our customers in the electric power industry. It brings many brands together thereby making it convenient for customers to have a single point connect for most of their T&M needs in the generation, transmission & distribution sectors. Moreover, an eventual consolidation of technologies will help standardise the offerings in line with the recommendation of IEC & IEEE and steering research and development. . What will be positive efficacy of combination of Doble- ALTANOVA? What are your ambitions and goals for the year – 2022?

For effective maintenance of key electrical assets, we realise our customers are looking for a focussed and simplified approach which helps them to take informed decisions; be it stand-alone testing, online monitoring, deployment of technical services or asset management systems. This combined entity under the Altanova brand shall stive to achieve exactly that.

The 2022 goals are short-term and more focussed towards building a strong & trusted Altanova brand. At the same time, it will be business as usual for our customers who now have a wider basket to choose from as all brands will co-exist with the choice always remaining with the customer. . What are the market’s challenges, particularly in terms of cost, technical advancement and getting raw materials?

The pandemic has wreaked havoc in the traditional supply-chain for everyone. Forecasting and planning has become a nightmare and delayed projects has added to the cost overruns. There is only a fraction that a small secondary equipment industry such the T&M space can absorb such shocks in a large EPC space. Unfortunately, the price pressure is transferred most on the secondary and tertiary equipment suppliers who are largely technologically oriented and not operating with high volume.

We are seeing a delay of about 30% in shipping times due to specialised electronic components crunch and feel it is only for the short term. Some designs are being adapted to accommodate new components. It is imperative we keep the customers in the knowledge of this – so they order with the quoted lead time & their projects are not delayed.

Technology advancement is done to ensure our products are available for service even after 5-8 years after they are discontinued. It is a big challenge as electronic parts these days have a shorter design life. Doble products are known to be robust enough to outlive its operational life which results in much lower ownership cost per year even if the initial purchase price seems high. . What is the testing and monitoring industry’s response to India’s ever- increasing claim for uninterruptible power?

A sure indicator of any developed nation is availability of a reliable electrical power network and quick restoration during shutdowns. This is possible only with correct planning of the network along with an effective operation & maintenance strategy. An accurate and effective protection and substation automation testing allows for proper mitigation of faults in addition to providing network information for better planning.

will help emerging economies like India take care of such assets. . Your prospect towards market requirements for monitoring solution?

As it is said, well begun is half done. An effective condition monitoring begins with proper planning at the engineering stage. It is not just about having sophisticated equipment connected to monitor your key assets. What technology to apply where and when is the key. This helps in getting more from the available budget.

Utility engineers should be aware that the key electrical power assts such as transformers, generators, motors and switchyards are designed for long life. Each stage of its life demands the right attention. Factory and commissioning tests demand accurate test results that serve as benchmark to compare on-site condition and provides a degree of confidence to connect this primary equipment to the grid.

As the market is gets more confident towards conditionbased maintenance and online techniques, proper technology intervention at the right stage is advised.

Keeping it simple in the beginning is the key. It is not necessary to have the most sophisticated technology connected right at the beginning of asset life to monitor it. It not only adds to the cost but may prove ineffective when needed a decade later if not looked after or due to obsolescence.

A judicious approach is what the market needs and it should be coupled with knowledge and intervention strategy when action is desired. RM

Union Budget 2022: Enormous push to infrastructure spending The Union Budget 2022–23, which announced a 35.4 percent increase in public capital expenditure, paved the way for capex-driven growth during India's Amrutkaal (i.e., the 25-year long period leading up to the 100th anniversary of Indian independence).

The capex has been increased from approximately Rs 5.54 lakh crore last year to around Rs 7.50 lakh crore in this year's budget, accounting for 2.2 times more than the FY 2019-20 outlay and 2.9 percent of India's GDP. Roads, trains, airports, ports, mass transportation, waterways, and logistics infrastructure will be powered by seven engines of growth that will be guided by the PM Gati Shakti National Master Plan against the backdrop of economic recovery from the epidemic provided by the Budget.

Union Finance Minister Nirmala Sitharaman announced a slew of infrastructure development plans, including a 25,000-kilometer expansion of the existing network of national highways and the development of four multimodal logistics parks, 100 cargo terminals, and eight ropeway projects under the Parvatmala scheme.

The development of these projects will not only improve connectivity, but will also have significant benefits for

||www.electricalmirror.net||

India's logistics sector, with the added bonus of good ripple effects on the construction industry as a result of their completion. PPP was the buzzword in this year's Budget speech, and nearly all infrastructure development plans, including the ones noted above, will be executed through the PPP model.

The expanded role of the private sector in nation-building is a positive step that will help to ensure quality in future infrastructure development.

The limited contribution of private investment in infrastructure development was also acknowledged in the Budget speech, and it is expected that increased public capital deployment will help achieve the goal of creating a virtuous investment cycle by pump priming private investment in infrastructure.

The government will be able to meet its capex requirements by issuing sovereign green bonds to support the development of green infrastructure in public sector projects, which will also result in the inclusion of green assets in the National Infrastructure Pipeline.

The holy trinity of India's infrastructure development efforts will be higher capex, the National Infrastructure Pipeline, and the PM Gati Shakti National Master Plan, which will ensure coordinated and timely project delivery.

The budget's sustained focus on supply-side reforms, while maintaining the infrastructure sector as its cornerstone, would work as a growth booster for the Indian economy, bringing it one step closer to its objective of becoming a $5 trillion economy.

A careful and timely implementation of the praiseworthy Budget promises would not only result in the development of world-class contemporary infrastructure, but also provide job possibilities for India's youth.

This macroeconomic expansion, combined with a microeconomic focus on welfare, would undoubtedly set the Indian economy on a path to long-term, sustainable growth.

The Union government has reaffirmed its commitment to using infrastructure as a force multiplier for sustainable economic growth in Budget 2022–23, with a budgeted infrastructure investment of over Rs 10 lakh crore and a capex increase of over 35% y-o-y. One of the primary focus areas in infrastructure is using multimodal transportation infrastructure to minimise logistics costs and improve India's overall competitiveness.

Similarly, the budget has emphasised the importance of collaboration across several ministries/agencies in order to identify and complete important projects on time. The Gati Shakti initiative, which is one of the centrepieces of Budget 2022–23, would solve both of these issues. Gati Shakti will be built on digital technologies, including GIS. To promote regulatory and operational simplification, the budget proposes a unified logistics interface platform for data interchange among multiple operators via APIs. Roads and railways have seen a large increase in outlays, with a year-on-year increase of more than 50%. Over the next three years, 100 PM Gati Shakti Cargo Terminals are envisioned as part of the rail connection. Similarly, it is planned to expand the national highway network by 25,000 kilometres

this year, which is roughly double the maximum accomplished in any of the previous five years.The proposed budget for urban infrastructure, housing, and ports has been kept at FY2021–22 levels, with the Jal Jeevan Mission budget being increased by 20%.

Let us now turn our attention to financing, which is addressed individually in the budget paper. With a total investment of Rs 111 lakh crore planned for the National Infrastructure Pipeline (2020–25), the target yearly investment is between Rs 20–22 lakh crore. The fiscal commitment of Rs 10-11 lakh crore reflects the Centre's 45 percent share of total infrastructure investments. The balance is expected to be made up of state governments and non-budgetary sources (banks and financial institutions), as well as private investment.

In areas where state governments have control, such as urban infrastructure, irrigation, health, and education, state governments are likely to play a stronger role. The budget has boosted the spending for "State Government Support for Capital Expenditure" from Rs 15,000 crore in 2021-22 to Rs 1 lakh crore in 2022-23 to incentivize them to improve infrastructure in these areas. This money would be handed to the states in the form of a 50-year interest-free loan, on top of the concessional financing already in place for Atmanirbhar Bharat reforms, asset monetisation, and other initiatives.

On the subject of private investments, a number of initiatives have already been implemented, including public-private partnerships, asset monetisation, the establishment of the National Bank for Infrastructure and Development (NABFID) as a development finance institution, and tax breaks for foreign pension and sovereign wealth funds. Green bonds and thematic funds utilising blended finance for supporting sunrise areas including deep tech, climate action, pharma, agri-tech, and others are also highlighted in the budget.

1. Introduction:

For the last few months, the response of the readers to the case studies on various incidents is overwhelming. Hence this month we are again choosing the write up on similar kind of studies for developing the synchronization of practical observation to the theoretical concepts. The analysis of each incident being supported by actual observations had been described during the situation to add awareness amongst the operation, testing and commissioning engineers to know the cause of problems and be helpful for easy rectification of the problems. This can also help to develop economic schemes for the smooth running of the operation and control system in the Grid Sub-Station.

2.1. Abnormal LBB Tripping:

At one of the 220/132Kv Grid Sub-Station, Fault on DEAD CIRCUIT (Shut Down Circuit) resulted with LBB initiation and tripping of all the breakers on the connected BUS. Observations: 1. One of the 220KV circuit was under shutdown at the Grid Sub-Station.

2. This Shutdown line was connected between two interconnected stations and fed through one of the circuit from the available DC (Double circuit) Tower system 56

3. The other circuit of this DC tower was in service and feeding the Power from one station to the other.

4. The Earth switch of the shutdown line was closed at one end (Say Station A) and the other end Earth switch was OPEN (Say Station B).

5. The closed Earth switch of the Shutdown feeder was having CT on the Line side.

6. There had been a fault on this tower line (Lightning strike) at around 15.8Kms away from the Total line length of 125Km. (Refer Fig 2.1.1) 7. The fault was recorded by the in-service line at Station A as Zone-1 Fault on R phase to ground and Zone-2 at the Station B. 8. But with of strange incident, it was observed with Fault on the DEAD LINE also (Shutdown Line) with Y Phase to Ground at Station A (Where the earth switch was in CLOSED condition).

3. The isolator logic was changed with BLOCKING of the tripping in case of ambiguity status with alarm indication for the operator to attend the problem.

4. The integration of LBB scheme was taken with Bus bar scheme and the CU was assigned for the decision to the tripping of the system.

5. The COMMON BUS trip logic was also changed to individual LOCKOUT Relay (96) for defined tripping of the involved bus breakers.

6. The system was taken into service OK TECHNICAL ANALYSIS 1. In this incident few peculiarities had been resulted as follows a. TRIPPING COMMAND to the DEAD SHUTDOWN line due to current flow in the CT b. Distance Protection tripping of DEAD LINE with ZONE-1 fault though current was to towards BUS, as Earth switch was closed keeping CT in the line. c. BLACK OUT of the station A due to tripping of all other breakers.

2. Tripping COMMAND for the DEAD Circuit: a. In this situation out of both circuit, circuit-1 was in service and circuit-2 was dead. But at the time of lightening, might be due to poor TFR (Tower footing Resistance), BLACK FLASH had been resulted with the R phase insulator string of circuit-1 and Y phase insulator string of circuit-2. b. Just after dyeing down of lightening effect and due flashing across the R phase insulator of circuit-1 and Y phase insulator of circuit-2, the available supply on circuit-1 from both side now contribute the fault current through R phase string and Y phase string. c. But circuit 2 was connected with EARTH switch being CLOSED at Station A before the CT. So current rushed through the CT and passed through the closed Earth Switch. Refer Fig 2.1.2.

9. This incident of DEAD line Fault indication was the surprise, as this line was in dis-connection from supply BUS from both end.

10. This Shutdown line was connected with secondary voltage from BUS PT supply by the PT selection relay as per the selection of isolator.

11. The BUS arrangement at station A was of TWO main bus with transfer arrangement.

12. On this day and in this situation the secondary status of the BUS-1 isolator of this feeder was in closed condition and BUS-2 isolator was in ambiguity situation (Neither in OPEN nor CLOSE).

13. So, due to this surprise fault current on shutdown feeder and availability of BUS PT supply, issued trip command to the OPEN Breaker by the actuation of Lockout relay 86.

14. So, the LBB feature on this feeder actuated (due to the condition of 86 operated, availability of fault current and elapse of threshold time). Simultaneously this issued command to the central unit of the Bus bar protection scheme and accordingly as per ZONE, the other connected breakers in this station tripped.

15. Because of this abnormal tripping, both the BUS connected breakers tripped and resulted with TOTAL BLACKOUT of the station.

Action Taken: 1. The logic provided with LBB relay was checked and found with the followings. a. External initiation with condition of 86 operated, availability of fault current and elapse of threshold time. b. The RETRIP feature on this was also checked and found with NON ADOPTION of this feature. c. The BACK TRIP was direct after initiation of LBB scheme. d. The threshold timing was of 200 msec.

2. On reviewing the above logic, it was planned/adopted with new addition/extra logic as follows a. The RETRIP functionality was added with logic of (Breaker status, Threshold time and availability of certain elapse time). (Ref Fig 2.4.2) b. This time the RETRIP was issued from the CU (Central unit) through BU (Bay Unit) to the affected breaker allowing the second attempt of tripping, if so tripped then LBB being the intermittent interruption used to save the system avoiding unnecessary outage. c. In case of the condition as available, the BACK TRIP to cause after elapse of certain timing and tripping of ZONE breakers as selected by BUS BAR SCHEME.

d. Because of this current availability in the Dead circuit CT and due to availability of PT supply, DP relay operated issuing the command to the OPEN breaker.

3. DP tripping on ZONE-1 though current in reverse direction: || February 2022 ||

Case Study

a. Here current recorded in Y phase CT, but its actual current phase is R phase as this is the extended current from the available supply of circuit 1. b. So its current shall be treated as R phase current in REVERSE Direction and positioned at the Y phase slot in the relay. c. So, in the DP measurement for fault loop shall be considered with VYN voltage and reverse R phase positioned at Y slot (Refer Fig 2.1.3.A and 2.1.3.B). d. Now this measurement got polarized as FORWARD ZONE for the DP relay on Circuit 2 at Station A.

4. BLACKOUT of Station A due to tripping of all breakers. a. As already mentioned that, this station has LBB scheme integrated with BUS BAR system. (Refer the LOGIC Diagram Fig 2.1.4)

Fig 2.2.1 Damage at PG strand

2. This Line was connected with Double jumpers and both the jumpers had been placed with connection of PG clamps 3. The actual jumper cone had been damaged, for which PG clamp was put in the system.

4. But the workmanship of putting the PG clamp was not to the mark due to intermittent gap in the overlapping groove of the PG clamp as seen from the fig 2.2.1.

5. The other similar type case with use of PG clamp and damage of strands has been shown in fig 2.2.2.

6. Moreover, both the PG Clamps were put nearby as shown here (Fig 2.2.1) , over the twisted conductor strands.

Fig. 2.2.2. Damage Strand at PG Clamp point

b. On the day of this incident, the LBB feature got initiated by the relay on the shutdown feeder due to flow of abnormal current. c. So, the actuation of all the breakers on BUS-1, caused outage of BUS-1 system. d. But due to ambiguity isolator position, the other healthy BUS also got tripped and resulted with SYSTEM BLACKOUT.

2.2. Damage of Main Conductor:

During Line Patrolling it was observed with damage of Main conductor strands of the 132KV Line conductor.

Detail Observation: 1. During Annual Tower climbing detail observation works, it was found with damage of few strands of the main conductor at the mouth of the PG clamp as like shown 58

in the fig 2.2.1, Fig 2.2.2

ELECTRICAL MIR ROR

|| February 2022 ||

Action Taken: 1. The Conductor was replaced with the new one on the allotted span.

2. Use of PG clamp was avoided. The actual Jumper cone was used for jumpering the line.

Technical Analysis: 1. PG clamp manufacturing and finishing of the product depends upon the format used in the manufacturing site. Sometimes due to improper pouring of the slag and availability of foreign impurities result with issues on the overlapping groove.

2. Due to this defect, the upper grip may not hold the lower one and during tightening of the bolts, if the work person does not do the correct tightening work, then its impact shall be on the strands of the conductor.

3. Moreover, due to environmental factors like abnormal seasonal heating and cooling may cause deterioration.

4. The deposition of water/moisture drops, dusts etc.. may ||www.electricalmirror.net||

cause rusting and cutting of the strands as like happened here.

5. Then during current flow, this damage becomes more, resulting with gradual failure. But in this case the string has not failed due to internal Steel wire strength as this conductor was of ACSR Panther type.

Recommendations: Avoid using PG CLAMP in Transmission line conductor as far as possible.

8. The other L pad and jumper cone connection was also checked, found in order with neither any scar nor any damage.

9. But it was advised for connection of the heakthy jumper cone towards insulator side, in stead towards conductor.

(As shown in fig 2.3.3).

2.3. Damage of L pad Clamp:

In one of the 400KV transmission Line , at one location , it was observed with damage of the L pad on the conductor string.

Observations: 1. This was 400Kv DC ( Double circuit ) transmission line tower with stringing of TWIN MOOSE ACSR conductor.

2. At one of the tensionTower, it was found with damage of the L pad at the hardware portion.

3. This was pointed out during the Binocular vision patrolling of the line.

4. So it was decided for the actual verification of the issue.

5. On availing shutdown and climbing on the tower, it was found with crack of the L pad and damage of maximum portion across with the pad.

6. So, the L pad was knowingly dis-connected from the system for rectification. ( Ref Fig 2.3.1)

Fig 2.3.1. damaged L pad

7. This time, for quick and temporary repair, PG clamp was used, till next action of replacement of the total conductor. ( Ref Fig 2.3.2)

Fig 2.3.2. damaged L pad and new connection

||www.electricalmirror.net||

Fig 2.3.3. Connection of Cone towards insulator side

Technical Analysis 1. The damaged piece of L pad was thoroughly checked and found with rust scar on the pad as like shown in the fig 2.3.1.

2. This was analysed and confirmed from the workmen on replacement job that the Jumper cone hole and Pad clamp hole was not in matching state.

3. So during the commissioning stringing time, the construction team had connected the bolts with only with TWO matched HOLES, keeping other TWO holes’ blank.

4. Due to this mismatch and improper contact surface, during load flow situation, the contact surface was resulting with heat and spark.

5. Then due to mechanical load tension and wind flow situation, the crack has developed on the L pad.

Recommendation:

1. Always use proper L pad and jumper cone with matching hole. Don’t let any holes’ blank during connection.

2. If possible, allow jumper cone to rest on the L pad. Allow Jumper cone fitting towards insulator instead Conductor hardware side as like symbolic fig shown (Fig 2.3.4) RM

Electric grid, identifying the challenges and the opportunities that led us to create one of the next-generation technologies Abstract Global Transformer Market Overview According to a recent market research report, the global Power Transformer (PT) market is exp’ to surpass $35 bn by 2024. Key market driver is the ongoing expansion of utility aided T&Dn/w’s to sustain the growing energy demand across the globe, as well as rising invest’s to refurbish the existing grid infra’ across developed regions & increasing demand for rural electrification across emerging electricity markets. Energy efficiency measures & expansion of smart-grid n/w’s will further accelerate the product penetration. Global PT market is exp’ to surpass $35 bn by 2024. In 2017, in compliance to the smart grid agreement, Sweden, France, Germany, Italy &UK proposed invest’s worth $133.7 bn with an aim to sustain the rapid smart grid adoption across the region, according to the report.

Future Growth The government’s commitment of 24/7 power supply will see spike in

||www.electricalmirror.net||

demand for transformers. Further, the target of generation of 175 GW of renewable power generation will generate significant demand.

Focus of government on railway electrification will lead to demand of electricity and transmission products including transformers.

Metros, dedicated freight corridors, high speed and semi high-speed rail continue to drive the demand further in the transportation sector.

With more and smarter cities projects coming up for implementation, the requirements for dry and distribution transformers will surge. Many of the MNCs are now putting up or expanding the data centre capacities in India, a trend which was in vogue in the US for last few years.

According to Sethi from ABB India, the aforementioned demand drivers have the potential to drive transformer industry growth in: • Large power transformers & reactors for generation plants & power evacuation and grid integration packages on tariff

based competitive bid route.

• Requirements from the State Transmission Utilities (STUs) and Central Transmission Utility (CTU) for 765 kV & 400 kV transformer & reactors – for grid interconnection.

• Power transformers up to 220 kV from state transmission utilities, renewable projects (wind & solar) and transport industry (railways, metros and freight corridors) • The distribution segment will see growth mainly from government initiatives such as power for all, metro projects, smart cities, data centers, wind power generation.

M Vijayakumaran from Prime Meiden expects that the electricity demand will continue to increase because of expansion of commercial and industrial establishment, and increased use of electrical appliances. The development of new power infrastructure and overhauling of existing one will also boost the demand for transformers. The power-starved countries in Africa, south America and ASEAN region are focusing on constructing power generation facilities in coming years. The developed countries are having over aged transformers which will have to phased out one after another by new transformers.

With electricity being a key element in the economic growth of the country, distribution transformers play a very important and vital role in delivering electricity to every corner of India. Atul Agrawal from Uttam (Bharat) Electricals states, “Distribution Transformers are key assets for any distribution network. It has been observed that the demand for distribution transformers are majorly taken care by the domestic industry players and the import of transformers is very marginal or project specific.

With industry dominated by unorganised players which are spread all over India on one hand and organised players on the other, both segments are parallelly working towards meeting the demand within India and abroad.

The transformers produced in India have been brought under mandatory BIS certification, resulting in standardisation of the product, which has resulted in improvement of quality and reduction of failure of transformers. The distribution transformers have also been brought under mandatory BEE star labelling scheme which has resulted in the use of modern technology in manufacturing energy efficient transformers.

“Replacement of old transformers with energy efficient ones will keep the momentum of up demand for transformers in the country,”.

factors for the growth of the market are the increasing demand for renewable invest’ &smart grid initiatives, while the restraining factor is cost barriers. Global T/R testing equipment market is exp’ to grow during 2017-27 due to the growing demand for safe & continuous T/R of electricity from the power generation plants to the end users & for this purpose, T/Rs are tested continuously in real time. Increasing energy demands lead to the growth of generation of electrical energy from both non-renewable & renewable sources, which leads to higher installations of PTs in the global market? This will accelerate the growth of T/R testing equipment market.

Countries of APEJ such as India & China have registered higher demands for energy, which drives the growth of T/R testing equipment market in the region.

Global HVDC converter station market is exp’ to grow from an est’ value of $7.9 bn in 2017 to $11.57 bn by 2022.Key factors contributing to the market growth is the increasing req’ for cost-effective solutions for bulk power transfer & increasing need for connecting asynchronous grids, which has driven a rapid adoption of HVDC in Europe & Asia Pacific, creating new market opportunities. >2,000 MW seg’ is projected to grow at the highest CAGR during, as the major problem faced by large economies such as India & China is to ensure efficient transfer of bulk electricity over long distances while maintaining the national electricity grid without any disturbance. Hence, many projects in the countries are developed in UHVDC. Europe market is exp’ to dominate the global HVDC converter station market, with the highest share as the major economies in the region such as the UK, Germany &France are developing inter linkage links b/w

of the large PT seg’ is higher & is due to the increase in HVDC T/R projects mainly in the Asia-Pacific region. HVDC, EHV & UHV projects being undertaken for reducing T/R losses during T/R over large distances is the major growth driver of the large PT market. Industry has been going through technological evolution & now the focus is on raising energy efficiency, given the urgency to fight climate change. ITMA has been working with govt’ to usher in technological changes & globally acceptable energy efficiency norms.

Indian T/R industry has been stagnant over the past 1-2 years due to slowdown in projects both in the power T&D sectors.

In addition, ambiguity around GST rates for capital goods products has added further to the business slowdown. It has also been observed that the no of projects, especially in the T/R sector which have been initiated have been put on hold due to delay in approvals & lack of funds. Currently govt’ is taking major steps to strengthen the power T&Dn/w’. Both power as well as distribution n/w’ is getting strengthened across the country. Govt’ initiatives like DDUGJY, IPDS & growing FDI in power industry are few growth drivers in the industry. Further, govt’ has projected an invest’ of INR 146,000 Cr. in the country’s T/R sector by FY 2019 which is bound to result in giving boost to demand for DTs& PTs. Mainly govt’ has undertaken initiatives such as UDAY for financial turn-around of discoms who are one of the main end users for the industry. With implementation of UDAY & other discom schemes there is a huge acceleration of infrastructural amendment in India. Moreover, discoms are instructed to reduce losses to the tune of 10-12% which means they must go for efficient T/Rs thereby influencing invitation for bids for refurbishment & up-gradation of existing T&D n/w’.

Also, a recent BIS circulation has issued strict norms on T/R losses. It is exp’ that in next 3 years’ time discoms will have to replace all existing T/Rs with level 3 T/Rs (5-Star Rated T/Rs). T/R manufacturers must manufacture & supply these new T/Rs in millions to the discoms in a max 3-year period. Demand from these schemes is exp’ to continue & in addition new schemes such as Saubhagya scheme which aims to provide last mile connectivity to rural consumers should increase future demand. Infra’ seg’s are witnessing increase in demand for DTs & increased govt’ spending in this seg’ is set to drive demand in future. Additionally, intra-state T/R projects (<=400 kV) are exp’ to drive demand for PTs. State TRANSCOS will majorly drive this demand & float new T/R projects through the TBCB model. PGCIL, which is mainly into executing & implementing interstate projects, is planning to aggressively enter intrastate projects by forming JV’s with state utilities. PTs hence also need replacement/ relocation || February 2022 ||

countries to maintain power efficiency.

Transformer Industry in India Increasing population along with increase in industrialization & urbanization led to increase in capacity utilization across sectors resulting in a surge in demand for power in India.

Today through reforms such as ‘Power for all’, govt’ plans to add 93 GW by 2022, that requires a sound power sully infra’ base in the country which is set to fuel the demand for power T&D equipment. Backed by govt’s on-going reform & financial restructuring drive in the energy sector, the country is now witnessing fiscal discipline in utilities, sufficient coal availability & an unprecedented growth in the green energy market. Hence, because of these initiatives Indian PT & DT market is exp’ to witness sig’ growth over the coming years.

Indian PT & DT industry is going to increase by > 10% CAGR in the next 5 years & the market is forecasted to reach $2.9 bn by 2022.Indian T/R industry has since its inception grown considerably. T/R manufacturers have also matured & demonstrated noteworthy technological advancements in recent years by developing T/Rs upto 1,200 KV ratings. Today, India’s domestic T/R market is valued at Rs 14kCr. in which PTs account for 45% while DTs make up the remaining share of 55%. As there is a demand upswing for reliable power in the country, the T/Rs market is witnessing a growth trend.

T/R industry which had more than doubled its capacity over the past years anticipating huge domestic & overseas demand was witnessing the situation of overcapacity. Yet, with a shift in govt’’s focus to strengthen the power T&D system has unleashed abundant opportunities for the PT & DT market. Even though market size of the medium PT seg’ is large, yet the growth

to less populated demand centre. Most of the solar power generation built last year is now almost connected to the national grid & often throwing huge power flow in the cycle which is meeting country 23% power demand in few demand centers during peak hours. Solar boom has crashed a new demand of Inverter duty special T/Rs. Widespread scenarios suggest an optimistic growth potential within the organized sector of the industry as only efficient & quality focused org’ can be benefited from such drivers. Despite the recent slowdown, Indian T/R industry will benefit from the strong demand exp’ from govt’ programs & invest’s that support the growth of the T&D grids. As govt’ aims to increase the RE generation capacity to 175 GW by 2022&to have RE account for 40% of installed capacity by 2040.In this scenario, solar T/Rs are exp’ to see a sharp rise in demand.

New hope of revival in the Industry T/R Industry is one of the key seg’s of the ‘Electrical’ capital goods industry. It is also considered as the bell weather industry for many other Electrical products markets such as Capacitors, Switchgears & Insulators etc. So, from an Electrical industry perspective, it is very imp’ to assess the state of the T/R industry for one to get a sense of the overall Electrical Products market. T/R industry in India is a highly fragmented industry with over 250+ players & the industry est’s from various bodies & experts put this est’ to be around 300-400 players. Over 250+ players to be active in this industry. It is est’ that the industry capacity in India is est’ to be over 1000 GVA.It has been under a rough weather over the last 2 years with demand stagnation in India. It is est’ to be stagnating b/w 250,000-280,000 MVA for the last 2 years & recently showing some signs of growth. In terms of sales by products, the PTs in MVA terms is clearly over 70% of this market while Distribution T/Rs account for > 30% of the market in MVA terms but could show a reverse trend when we talk in terms of no of Units. The industry is governed by mostly the Oil Filled T/R industry & Dry Type of T/Rs have not yet gained full acceptance due to their high costs. Copper windings still account for a major portion of the industry, while Aluminum windings are mostly limited to < 250 kVA levels. Due to various factors & the state of DISCOMS largely, we are still hovering around the 8 to 8.5 MVA/MW levels. Utilities demand for T/Rs is a highly imp’ one & accounts for > 90% of the industry’s output. Remaining being the Industrial req’ of T/Rs for their projects. Over the last 2 years, the lack of new T/R project orders, poor state of the DISCOMS & the tepid industrial activity had kept the industry in a low performing state with demand stagnation.

Pervasive activities of the GoI in the Energy sector & overall positive invest’ climate has led to most players feeling more hopeful on the industry prospects. Though the actions have not led to a huge increase in order booking yet, but most industry players are seeing signs of revival & expect this to open soon. Opening of new T/R projects & the de-bottlenecking of old stuck projects has led to order wins by many firms in the recent past for the PTs. Imminent new T/R projects & the Green Energy Corridors will see more uptick in the PTSeg’ going forward. UDAY scheme &the participation of 15 states already in the program has given many players some hope that the fiscal conditions of DISCOM’s would improve & this would lead to more aggressive DTR purchases in the next few years to reduce the losses. Though GoI announced 2 major schemes of IPDS for the Urban areas & DDUGJY for the Rural areas, nothing of note till now has been seen on ground from these schemes. But, with UDAY being implemented in many states, this will provide a framework for most utilities to absorb the additional invest’s in IPDS&DDYGJY programs & implement them on the ground more effectively. Revival of invest’ in manufacturing & new CAPEX invest’s due to ‘Make in India’ has not yet happened but most industry players are cautiously optimistic about the same.

Market worth Growth is due to the increase in HVDC T/R projects mainly in the Asia-Pacific region. HVDC, EHV &UHV projects being undertaken for reducing T/R losses during T/R over large distances is the major growth driver of the large PT market.

PT market is projected to reach a value of US$ 29.91 bn by 2020, from an est’ US$ 20.71 bn in 2015 at a CAGR of 7.6% from 2015 to 2020. Increasing energy demand coupled with rising electrical infra’ projects would drive the demand for PTs. Apart from this, the replacement of aging infra’ in North America & Europe & increasing rate of installation of green T/Rs are driving the PT market. Although the market size of the medium PTseg’ is large, yet the growth of the large PTseg’ is higher. This is due to the increase in HVDC T/R projects mainly in the Asia-Pacific region. HVDC, EHV &UHV projects being undertaken for reducing T/R losses during T/R over large distances is the major growth driver of the large PT market. The oil-cooled PTseg’ occupies a larger market size as it is considered a safer option while handling high voltages. With increasing no of HVT/R projects being undertaken, demand for oil-cooled PTs is exp’ to be higher than air-cooled PTs. PT market is driven by increasing global energy consumption; to fulfill this, new T&D lines are being installed. Also, invest’s being made by GoI in electrical infra’ ||www.electricalmirror.net||

projects have also gone up, further aiding in the growth of the PT market. Asia-Pacific is the largest market for PTs &its demand in the region is mainly driven by extensive T&D n/w’ expansion projects in developing countries such as India & China.

Indian T/R manufacturers witnessed improvement in financial performance, with moderation in raw material prices & revival in order inflows. Amidst a few early signs of revival in performance & exp’ pick-up in demand, the outlook is exp’ to be stable in near to medium term. CARE believes that planned invest’s in power sector, replacement demand, export potential & development of inter-regional capacity is likely to sustain the demand of T/Rs in near to medium term. Income of T/R manufacturers is likely to sustain in near to medium term. Further, moderation in inflation & exp’ reduction in interest rates has the potential to improve the profitability due to high working capital borrowings. It is believed that no incremental long-term debt would be raised considering the present surplus manufacturing capacity. Yet, extent of working capital borrowings would depend on timeliness of payments from state utilities & private players. Moreover, enhanced share of private sector participation would be crucial to boost execution in power generation sector which would also lead to faster roll out of T/R orders. Lastly, credit quality of Indian T/R manufacturers is exp’ to remain stable in near to medium term with a stable outlook on industry.

A transformer is a static device used either for raising or lowering the voltage of an AC supply with a corresponding decrease or increase in current. By electromagnetic induction, an alternating current of one voltage is transformed to another voltage, without change of frequency. It essentially consists of two windings, the primary and secondary, wound on a common laminated magnetic core. Depending on the number of turns on each winding, transformers are classified as a step-up transformer or a step-down transformer. Step up transformer has more turnings on the secondary coil than on the primary coil and therefore the voltage induced in the secondary coil is larger than the primary coil voltage.

Transformers are widely used in electrical apparatus of all kinds and in particular in power transmission and distribution.

Power Transformers A Power Transformer transfers energy between high voltage and very high voltage systems, i.e. between generators and transmission systems and between transmission systems and distribution systems. Also, they are used in transmission network for stepping up or down the voltage level. It operates mainly during high or peak loads and has maximum efficiency at or near full load. A single-phase transformer is basically

made out of two separate windings that are inserted into each other into a closed loop of magnetic core. Moreover, the Joules heat effect is proportional to the square of the current transmitted into any ordinary conductor like transformer windings or transmission lines. Both these effects combined at constant power of elevating voltage reduce heat dissipation accordingly by the square of the current, and enable the transmission of power of alternating current and voltage over very long distances from the energy producer to the energy consumer while limiting the power losses in the grid. This is possible due to a key grid component the power transformer.

Most of them are the three-phase transformers or the three single-phase transformers. Thus from these electromagnetic principles, with the voltage increase of an electrical network, the Joule losses are reduced and the two main constraints of power transformers are high voltage and high current, depending on whether the HV or LV is observed.

Windings The active part of a transformer is made of the elements that are in contact with the voltage and the current, and are mainly composed of windings, core, and tap changer bushings. The windings are handmade out of copper coils insulated mainly with several layers of paper between the turns. The two main winding designs and technologies have been developed over time with many variations: the core type and the shell type windings. The electromagnetic basis remains the same in both cases but the mechanical construction is different. In the core type design, the winding is “enclosing” the magnetic core legs, while in the shell type the core is “enclosing” the windings. Every transformer manufacturer has its own experience with these technologies, neither of which is automated. The manufacturing of windings involves a lot of human labour and requires significant experience as well as application of the highest quality standards. This is because winding conductors are covered by a type of insulation such as varnish or insulating paper with a limited mechanical and thermal stability. Nevertheless, this insulation type provides protection from high over-voltages, high over-currents, short-term overheating, and high mechanical stresses in order to prevent reduction of the insulation paper durability.

It must be taken into account that the winding insulation cannot be easily repaired or replaced during the service life of a transformer and rewinding has to be performed only in a specialised workshop.

magnetic flux. In power transformer, the flux density is higher than the distribution transformer. It is made from thin steel sheets with the thickness of a few tenths of a mm in order to reduce losses and magnetising current. The main way to produce a core is to stack the sheets, cut to desired size, onto the automatic machines, and then manually stack them to build a core. The main core parts are the legs i.e. vertical parts, and yokes i.e. horizontal parts. The legs are mainly situated in a same plain. Most transformers have additional turns added to the HV windings and some of those turns are linked to a device called the “Tap Changer”. It enables a specific range of the voltage variation during the transformer service life. The electric circuit of the windings and the tap changer has some movable contacts. The two main types of tap changers are the De-Energised Tap Changer (DETC), mechanically quite simple type that changes the voltage while the transformer is not loaded; and the On Load Tap Changer (OLTC), a more complex type which operates when the transformer supplies the load. It should be noted that the tap changers, the OLTCs in particular, are contributing to an increasing transformer failure rate, mainly due to the movable contacts wearing over the years i.e. hot spots, aging mechanisms.

Bushings The bushings are the components that link the windings to a network through the grounded tank. High voltage bushings can be technically complex and, in some cases, their failure can lead to a transformer explosion quite rapidly. This is because one of the highest voltage gradients is between the HV bushing central part at full potential, and the grounded tank at the distance of just a few centimetres. The insulating oil just below is very flammable and if the bushing is sparking, it could generate a lot of energy, open the tank slightly and then ignite the oil, which could lead to an explosion. For this reason, the HV bushing is manufactured to withstand very high voltages within a small space filled with paper and oil between the bushing and transformer tank.

Insulating materials The three major insulating materials for the power transformers are: mineral oil and paper and pressboard in different forms.

The mineral insulating oil is weighted in tons within the tank and can be used to assess many essential points about the condition of a transformer and some critical incipient faults.

The paper insulates the winding turns, while the pressboard strengthens the electrical insulation and provides dielectric distance at specific locations, for example in the main duct between the windings. Insulating materials, such as paper, pressboard and mineral oil are organic materials subject to

aging. As the solid insulation cannot be repaired or replaced easily like other transformer parts and components, it limits the transformer service lifetime. Therefore, the solid insulation lifetime is the lifetime of a transformer.

Trends in Power Transformers Dry formers Recently, HV cross-linked polyethylene (XLPE) cables are used in these transformers. Dry former is an oil free HV transformer based on cable technology used in Power former.

Forced-air cooled, it has innovative windings made from XLPE cables with circular conductors. The absence of oil means that there is no risk of ground or water pollution in the event of damage and a less risk of fire or explosion. Therefore, Dry former can be sited closer to the consumer, for example below ground and in urban or ecologically sensitive locations.

As the electric field is fully contained within the XLPE cable and the cable surface is at ground potential, Dry former offers unique opportunities for optimising power transformer design. By using the state-of-the-art of cable technology, XLPE cable can have electric field strengths up to 15kV/mm.

From a manufacturing perspective, the Dry former has the considerable advantage of having the insulation system built up at the cable factory.

Gas-insulated transformers (GITs) In GITs, SF6 gas is used as insulation media with relatively low gas pressure. The principal solid insulation material for the GIT winding is polyethylene terephtalate (PET) and polyphenylene sulphide (PPS) films which are defined as class E insulating material with a temperature limit of 120 C. It has been initially specified to operate GITs, especially the gas-natural air-natural (GNAN) distribution GIT, with top gas temperature limit of 110 C instead of the maximum conventional 95 C top oil temperature for oil-immersed transformers. There have been a number of such interface problems for those heavily loaded GIT caused by gas temperatures higher than 100 C. Corresponding counter measures, such as oversizing the first section of LV bus bar, adoption of higher temperature class bushing material, and modifying clamping design to absorb higher temperature fluctuation have to be introduced. GIT have the following advantageous: Non-inflammable and non explosive, hence they are usable for multi-storeyed buildings, underground markets and other overpopulated places.

Moisture resistant and dust resistant, therefore, they are unaffected by open air moisture, dust and other ambient conditions since the windings and core of these transformers are fully enclosed in mild steel box and sealed with SF6 gas. ||www.electricalmirror.net||

In addition, they have easy maintenance and check because these transformers are hermetic sealed with an inert SF6 gas and materials are scarcely deteriorated.

Clean as there are no contaminations to surroundings since these transformers are sealed with non-poisonous, odourless SF6 gas, even if the SF6 gas leaks unlike mineral oil-immersed transformers.

Higher reliability with simple internal structure.

Better compatibility with gas-insulated switchgear (GIS).

GIT with on load tap changer (OLTC) used to be the most vulnerable part of any power transformer from electrical and mechanical points of view. In line with the use of SF6 gas as insulation media, vacuum switch type OLTC is installed for transmission GIT at 30 MVA and above. These vacuum switches housed inside the gas chamber are used as diverter switches and no arcing product can be possibly produced. Such OLTC is basically maintenance free. In the extreme case when OLTC malfunction due to mechanical defect or connection problem, the damage will be minimal. GIT turn out to be cheaper than oil immersed transformers when maintenance costs are considered. Power-distribution transformers have a high recycling value because they can be easily disassembled and their chief constituents, which are high-purity steel, aluminium and copper, can be recycled indefinitely. GIT are far more easily recycled than oil-immersed types.

Distribution Transformers Distribution transformers are units of electric power systems, in which electricity is transformed from the voltage level 1 – 50 kV to the voltage level 120 V + 1 kV, in dependence

ELECTRICAL MIR ROR

on consumer’s needs. Energy efficiency of distribution transformers is very high, typically ranging between 96 per cent and 99 per cent. However, due to a large number of distribution transformers in electric power system and their long lifetime (30 – 40 years), even small improvement in the efficiency of these units could result in significant energy savings. These issues are important both from economic and ecological viewpoints. Increase of energy efficiency of distribution transformers could be obtained reducing three types of transformer losses: No-load loss (iron or core loss) can be reduced by improvement in design and assembling processes or in magnetic properties of material core, Load loss (copper loss) can be reduced increasing the crosssection of the windings, Cooling loss can be reduced by decrease of other types of transformer losses.

Further increase in transformer efficiency is possible to reach by replacement silicon steel cores with new types of magnetic core materials, e.g. amorphous ribbons. These materials are produced by rapid solidification of a liquid alloy, what gives specific magnetic properties, especially very low energy loss.

However, these materials have quite low saturation induction and they are thermal unstable.

Experiment to address new grid management challenges Drawing attention on the changing scenario, Pedro Puente, R&D Director at Prolec GE, said, “After all the research, development and thorough testing, the new flexible transformer technology has begun a field validation to authenticate its performance and demonstrate how this technology could lead to a major grid management change. It is exciting for us to participate in the transformation of the nation’s electric grid, identifying the challenges and the opportunities that led us to create one of the next-generation technologies for the efficient, resilient, and reliable delivery of electricity. The innovative flexible impedance technology has been successfully patented.”

The timely action As Ndiaye pointed out, the introduction of new transformer technologies is coming at a pivotal time for the (US) nation’s grid infrastructure. Today, more than 70% of the U.S installed large transformer base (>60MVA) is 25-years or older, with around 15% exceeding the average life expectancy of 40 years. Gradual replacement of the existing fleet with more flexible power transformer solutions would greatly expand the grid capacity and accommodate more renewable resources and highly variable loads.

India are looking forward to making their setups as manufacturing base for supplying to other countries Fibre metal laminates (FMLs), as a class of hybrid material taking advantages of both metals and composites, have shown great promise as lightweight structural materials in the transportation industry. Accordingly, manufacturing technologies of FMLs are attracting increasing research interests. This review emphasises the developing technologies of forming FML components, with other aspects related to FML materials being briefly introduced. First, we provide an overall review of the historical background and recent developments of FMLs, their classifications, sheet fabrication processes, and their advantages and disadvantages.

Inadequate supply of prime quality CRGO steel is the biggest challenge in the country. CRGO req. is completely met through imports; it is in fact challenging to assess true quality of the material that is used by the

T/R manufacturers. India needs 2.5 lakh T of CRGO every year & an appalling 70% of this is scrap grade material.

Failure rate of T/Rs – High failure rate of DTs, is a big concern for the T/R industry in India. Avg. operational life of a T/R is b/w 25-30 years; Yet, T/Rs are known to be recalled for repair in as early as 3 years. Failure rate of DTs in India is est. at 10-15%. This is due to the low entry barriers in the DTs market leading to unorganized players entering the market, & competing on the price factor. SEBs historically follows L1 vendor selection criteria, which has led to proliferation of many small players that compromise on quality of T/Rs manufactured. Poor financial Condition of SEBs has restricted pvt. invest. in the power T&D sector, thereby reducing the quality of service from SEBs. Which, in turn, is affecting the capacity building program & transmission of power? The growth in testing infra. has not kept pace with that of production, both, quantitatively & qualitatively.

Testing infra. available at India's premier agency, the CPRI is proving short of demand. Manufacturers of large power T/ Rs at times need to send their equip. for testing to overseas facilities like KERI & KEMA which is expensive. Apart from this, huge logistical costs & lead times are also involved.

Development, Physical properties & Application of CRGO & CRNGO In recent years, as an aspect of global trend towards energy consumption & preservation of the environment, reduction of electrical consumption has become an extremely essential affair. Due to such global movement of environmental protection, energy saving & noise reduction have been req. for T/Rs, leading to a demand for lower core loss & lower magnetostriction material. Si steel is a soft magnetic material mainly used for T/R cores. It is a material of prime importance in the electrical industry & is been consumed in hundreds of thousands of tons every year. Pure iron has exceptional magnetic properties. One of the properties is its very high saturation magnetization. Pure Iron is, yet not used for electrical applications, instead electrical steels are used in many engineering applications. Electrical steels are also absolutely needed for the electrical power industry, as there are no obvious cost-effective alternative materials available.

Most electrical steels are Fe alloys with characteristic alloying additions. Most important alloying elements are Si & Al. Both are strong ferrite-stabilizing elements & their addition may limit the austenite phase stability to the extent that is not present during heat treatment.

Currently, India consumes about 2.5 lakh MT PA of CRGO

ELECTRICAL MIR ROR

|| February 2022 ||

electrical steel & with the growth in demand of transformation capacity the consumption is est. to be 11.5 &13.5 Lakh MT resp. during the XIIth & XIIIth plan period. Against this demand, only SAIL-RSP & Raymond steel has CRGO Production facilities. SAIL produced a small quantity in early 1990s&thereafter discontinued CRGO production. Only 5 global steel makers have the tech. to produce such steel, which India imports around USD 2 bn annually. Plan to produce CRGO has been with steel ministry for quite some time. NML & Tata Steel's proposal for development of CRGO steel in the country through a pilot plant setup at a cost of Rs 500 Cr. is set to take off soon. NML & Tata Steel would set up a pilot plant having a capacity of 3-5 T in Jamshedpur.

The 2 will give Rs 170 Cr. each to the project & balance is likely to be funded by the Steel Ministry for procuring plant equip. The Working Group on Steel Industry for XIIth FYP in its report had recommended inclusion of development of CRGO steel as a high value project of national importance.

It had also suggested a budgetary allocation of Rs 150 Cr. for research on CRGO development during the XIIth FYP period. There are a couple of public sector CoS including JSW Steel, that have already announced plans to produce CRGO through JV mode, but production from them will take some time to start. Public sector units – SAIL & RINL - have also evinced interest to venture into the area. Yet, Steel Ministry's Empowered Committee (EC) for R&D, said the JVs undertaken by Indian steel firms cannot ensure total tech. transfer. Even if they do, it will cover only normal grades.

Steel firms having the tech. to develop CRGO are very reluctant to transfer that to India. Hence, felt that dev of the tech. through indigenous sources through a pilot plant was a necessity. According to CEA, T/R industry of the country has grown to a manufacturing capacity of 800-1000 GVA. Given these daunting req’s, the need for higher capacity T/ Rs is imminent. India's CRGO steel consumption thus would sig. increase from the current level of $ 2 bn.

In 2010, around 400 MTs of electric steel were produced globally, making around 29% of total steel production.

The share is close to about 50% in Europe & to some extent even sig. higher in North America, Africa, India & the Near East. In total production of GO steel, % of high grade GO steel, HI-B is still around 20%, which is a very small when compared to the benefits of HI-B. This is due to many metallurgical problems observed in production of HI-B such as high slab reheating temp (>1300 OC) for the formation of Austenite phase in desired %, restriction in ||www.electricalmirror.net||

non-oriented Electrical steel, which is used extensively where a low-cost, low-loss material is needed, particularly in rotating equip. Mention should also be made of the relay steels, used widely in relays, armatures & solenoids. Relay steels contain 1.25-2.5% Si, & are used in DC applications because of better permeability, lower coercive force and freedom from aging. Resistivity, which is quite low in iron, increases markedly with addition of Si. Higher resistivity lessens the core loss by reducing the eddy current component. Raising Si content will lower magnetostriction, but processing becomes more difficult. High Curie temp. of iron will be lowered by alloying elements, but decrease is of little importance to user of CRGO Electrical steels. Magnetization process is influenced by impurities, grain orientation, grain size, strain, strip thickness & surface smoothness. One most important ways to improve soft magnetic materials is to remove impurities, which interfere with domain-wall movement; they are least harmful if present in solid solution. Compared with other commercial steels, Electrical steel is exceptionally pure.

Because carbon, an interstitial impurity, can harm low induction permeability, it must be removed before the steel is annealed to develop the final texture. Mechanism for the growth of grains with cube-on-edge orientation during the final anneal is not completely understood. Process involves secondary recrystallization, which, by def, is characterized by accelerated growth of one set of grains in an already recrystallized matrix. For secondary recrystallization, normal grain growth must be inhibited in some manner. As temp. is raised, certain grains break loose from inhibiting forces &

increment of Si % & restriction in decreasing the gauge of product. But new developments are also taking place like acquired inhibitor method, in which N2 gas is injected by using NH3 gas after decarburization. This method decreases reheating temp. of slab & hence ensures better performance of electrical machines. Such inferior material causes T/Rs to fail faster debilitating the country's power distribution infra. Thus, CRGO is going to play an imp. role in sustaining India’s economic development. Hence, focus should be given in R&Ds of high grade GO in India.

Grain oriented Electrical Steel CRGO is undoubtedly most imp. soft magnetic material in use today. Whether in small T/R, DT or in large T/R& generator, CRGO is a must for the production of energy saving electrical machines. Grain oriented Electrical Steels are iron-Si alloys that provide low core loss & high permeability needed for more efficient & economical electrical T/Rs. CRGO Grain oriented grades of electrical steel are typically used for T/R cores & large generators. Non-oriented Electrical steel CRNGO fully processed steels are iron-Si alloys with varying Si contents & have similar magnetic properties in all directions in plan of the sheet. Non-oriented Electrical steel are principally used for motors, generators, alternators, ballasts, small T/Rs & a variety of other electromagnetic applications. The earliest soft magnetic material was iron, which contained many impurities. Research found that the addition of Si increased resistivity, decreased hysteresis loss, increased permeability & virtually eliminated aging. Substantial quantities of CRGO are used, mainly in power & DTs. Yet, it has not supplanted

grow extensively at the expense of their neighbors. Producers know that, on a practical basis, appropriate cold rolling & recrystallization sequences must be carefully followed to obtain the desired secondary recrystallization nuclei & the correct texture.

Imports of CRGO steel increased in double-digits for the years 2014 & 2015. On a YoY basis, it grew by 29.9% to USD 433 mn in 2014 & by 18.2% to USD 511.6 mn in 2015. Following this, the imports declined by 5.5% to USD 483.5 mn in 2016. The imports of CRGO steel are mainly made from Japan. Of the total imports (in value terms) of CRGO steel made by India in 2016, 25.6% of the imports were from Japan followed by22.9% from Russian Federation, 14% from Republic of Korea, 10.7% from China, 6.7% from USA. GoI gave nod for policy that provides preference to domestically produced steel to be procured by govt. for its projects. Import duty cut on input products for CRGO steel will reduce cost of its manufacturing. Such move will encourage domestic producers to produce CRGO steel that is otherwise imported, which in turn would mean reduced costs for electrical & power T/R& lamination CoS. What is T/R Lamination You may be wondering as to how the primary & secondary

ELECTRICAL MIR ROR

windings are wound around these laminated iron/ steel cores for T/R constructions. The coils are firstly wound on a former which has a cylindrical, rectangular/ oval type cross section to suit the construction of the laminated core.

In both the shell & core type T/R constructions, in order to mount the coil windings, the individual laminations are stamped/ punched out from larger steel sheets & formed into strips of thin steel resembling the letters E’s, L’s, U’s & I’s. These lamination stampings when connected together form the req. core shape. For e.g., two E stampings plus 2 enclosing I stampings to give an E-I core forming one element of a standard shell-type T/R core. These individual laminations are tightly butted together during the T/Rs construction to reduce the reluctance of the air gap at the joints producing a highly saturated magnetic flux density.

T/R core laminations are usually stacked alternately to each other to produce an overlapping joint with more lamination pairs being added to make up the correct core thickness.

Such alternate stacking of laminations also gives T/R the advantage of reduced flux leakage & iron losses. E-I core laminated T/R construction is mostly used in isolation T/Rs, step-up & step-down T/Rs as well as auto T/Rs. Insulation used to prevent the conductors shorting together in a T/R

is usually a thin layer of varnish/ enamel in air cooled T/Rs. This thin varnish/ enamel paint is painted onto the wire before it is wound around the core. In larger power & DTs conductors are insulated from each other using oil impregnated paper/ cloth. Whole core & windings is immersed & sealed in a protective tank containing T/R oil. T/R oil acts as an insulator & also as a coolant.

Eddy current losses within a T/R core cannot be eliminated completely, but they can be greatly reduced & controlled by reducing the thickness of the steel core. Instead of having one big solid iron core as the magnetic core material of the T/R/ coil, the magnetic path is split up into many thin pressed steel shapes called “laminations”. The laminations used in a T/R construction are very thin strips of insulated metal joined together to produce a solid but laminated core. These laminations are insulated from each other by a coat of varnish/ paper to increase effective resistivity of core hence increasing overall resistance to limit flow of eddy currents. The result of all this insulation is that unwanted induced eddy current power-loss in the core is greatly reduced, & it is for this reason why the magnetic iron circuit of every T/R & other electro-magnetic machines are all laminated. Using laminations in a T/R reduces eddy current losses. Losses of energy, which appears as heat due both to hysteresis & to eddy currents in the magnetic path, is known commonly as T/R core losses.

Since these losses occur in all magnetic materials as a result of alternating magnetic fields. T/R core losses are always present in a T/R whenever primary is energized, even if no load is connected to secondary winding. Also, these hysteresis & eddy current losses are sometimes referred to as T/R iron losses, since the magnetic flux causing these losses is constant at all loads.

Bottlenecks Long overdue demand of T/R Industry to govt. is to pursue CoS like SAIL/ Tata to set up manufacturing plant in India which would save considerable FOREX outflow. Indian power T/R market is set to grow at a CAGR of 14% b/w 2013-18. Yet, challenges are many.

Indian steel producers should be forced to set up CRGO plant to meet the demand. India is known to be an active supplier of T/Rs globally. India has always been an exporter of T/Rs & this avenue is set to become even more lucrative in the coming years. Exports from India are diverse including PTs, DTs & even special purpose T/Rs. It is est. that around 15% of India’s production

ELECTRICAL MIR ROR

|| February 2022 ||

of PTs is destined for int’l markets. With India proving its technological edge by producing even 1200kV T/Rs, surpassing global standards, the country has a very bright future. It is not only developing African & Central Asian economies that are importing from India; India-made T/Rs are even finding their way in developed markets like USA, UK, Canada, South Africa etc. India has been net exporter of T/Rs till now. Several of int’l players who already have base in India are looking forward to making their Indian setups as manufacturing base for supplying to other countries. Indian T/R industry is gradually gaining prominence in developed markets on the basis of its quality & pricing. Domestic T/R industry has potential of becoming manufacturing/ sourcing hub for supply of T/Rs in foreign markets. This market is highly fragmented with a large no. of small & medium enterprises involved in manufacturing processes, & is dominated by organized players. Domestic manufacturing industry is fairly well established with manufacturers having capabilities to develop all type of T/Rs up to the 800 kV & 1,200 kV levels. The industry also exports to several countries including the US, South Africa, Cyprus, Syria & Iraq, apart from Europe.

Way Forward India is on the verge of becoming an emerging power nation among developing economies. Availability of electricity is directly linked to the GDP growth of developing economies, India being no exception. Growth of Indian electrical industry & its invests appeal primarily depends on govt. policies. Timely capacity additions to electricity generation, T&D are necessary to improve & sustain GDP growth & reduce demand-supply gap. Indian PT & DT markets are highly dependent on invest’s planned by the GoI for T&D segment &reform programs like RAPDRP & RGGVY. These programs, when fully implemented as scheduled, are expected to drive demand for both PTs & DTs. GoI currently plans to strengthen transmission lines & create a National Grid interconnecting the 5 regions (NR, SR, ER, WR,NER) through creation of Transmission Super Highways & is expected to drive demand for higher-rated PTs. With T&D CoS actively striving to reduce AT&C losses, demand for energy-efficient T/Rs would get a boost. With huge invest’s proposed across sectors such as power, infra., T/Rs market in India is slated for strong growth. Excess capacity in T/R industry in India & entry of new players will increase market competitiveness.

Market consolidation over next few years is inevitable. RM ||www.electricalmirror.net||

Future challenges & growth of automation in India The current automation scenario in the manufacturing sector, islands of automation have created several challenges, as the lack of integration has impacted on operational improvements.

While developed countries have already started to focus on integration, the Indian manufacturing sector is still in the early stages of adoption of manufacturing solutions. As “India has the second largest pool of scientist and engineers in the world”, it seems that the lack of adoption is due to a gap in the suitability of existing technology to implement or adapt. In India, around 1% of manufacturing GDP comes from automation, whereas in developed economies the percentage is closer to 5%. India needs to “go Global” and that is possible only with enhanced investment in automation. With the government announcing and supporting various schemes, India is already on the right path towards globalisation.

The growth of a Country depends upon the certain basic pillar of infrastructure and one of such basic infrastructures is availability of quality and reliable power in the country. The country needs 24x7 uninterrupted power supplies to all the consumers along with transparency in the operation of sector and consumer participation. Power system automation

||www.electricalmirror.net||

included monitoring, evaluation, analysis, and control of processes associated with generation, transmission and distribution of electric energy from power stations to customers. Three main processes are included namely data acquisition, power system supervision and control, all working in a coordinated automatic fashion. Data acquisition refers to collect data in the form of measured analog current or voltages values or the status of devices (open or closed). Power system supervision is carried out through the acquired data either at a remote site or locally at the device site. Control refers to sending command messages to operate power system devices such as circuit breakers.

Automation plays a major role in the success of effective decision making at the utility level. Real Integration of automation not only helps to fulfil that promise, but enhances the opportunities to add more value and effectiveness to the energy value chain and also paves the way for moving forward towards the “SMARTER GRID”.Technological advancements and innovations driven by rapid electrification of segments like transport, expansion of renewable and digitalization of the grid are transforming the power sector. With decentralization, de-carbonisation and

deregulation, the entire business model of utilities is evolving rapidly and state-of-art technologies are making those changes possible that were beyond the imagination a few years back. These technologies are gradually making inroads in the Indian power sector as well.The requirement for making coal fired stations intelligent arises from the bead for highly efficient plant operation and asset management on one hand and wide scale penetration of renewable energy into the grid which results in rapid cycling of the thermal plants, on the other hand.

It is expected that several operational challenges will arise due to this interconnection and additionally due to the sustained increase in the generation coming from renewable energy, contributing at present more than 20% of the produced energy. Traditionally the main issues related with the operation of an electric system have been those concerned with the control of the frequency and voltage for reaching stability of these variables. Power generation plants have systems that control the injected active and reactive power to the network. However, the growth of this electrical system is leading to more requirements in data acquisition, data processing and control systems. Automation in the management of renewable energies is required considering that due to the variability in the available power, they introduce new uncertainties and parameters’ variations into the power grid, so that automation systems are required to connect these generation systems to the network and inject the corresponding energy in a coordinated way.

India’s power transmission segment is also growing at an unprecedented pace mainly due to the thrust provided by the recent policy and regulatory development as well as the government’s initiatives. The pace of expansion is expected to continue in the future to help meet the government’s 175 GW renewable energy power. While most of the future investment will be for the expansion of physical grid infrastructure, utilities are expected to invest significant sums in new technologies to make grids more reliable, resilient, secure and smart.

In the power sector, automation will help in monitoring and predictive maintenance of a wide variety of assets in its value chain. The equipment’s are monitored continuously and the collected data is passed on to cloud. On the basis of the collected data, a conclusion can be drawn on the health and impending failure of the assets by using Artificial Intelligence, and determine the optimal time to perform maintenance. The proactive predictive nature will enable

ELECTRICAL MIR ROR

|| February 2022 ||

the utilities to schedule the maintenance in advance and also avoid major shut downs and down time. That also means considerable savings in time and cost.

Need of Automation in Power Sector Power generated at voltage levels of 11to 33KV, has to be stepped up to high/extra-high voltagesand then again reduced instages to lowest distribution voltage level of240/415 volts. For maintaining these voltage levels and forproviding stability, a number of transformationand switching stations have to be created inbetween generating station and consumer ends. These grid sub-stations are requiredto be developed to achieve reduction in systemmalfunctions as well as reduction in themeantime to repair. Consequently, human interference and outage times also need to be reduced leading to a significant decreasein the energy losses.

The electricity grid has grown and changedimmensely since its origins, when energy systemswere small and localized.

With the passing oftime, rising electricity consumption, new powerplants and increasingly decentralised generation (DG) of electricity from renewable energiesrequire grid expansion. However, simplyexpanding the grid, as it is constructed now would be highly inefficient. The wildly fluctuatingpower feed-in from renewable energies (solar, wind) into the entire power grid occasionallyleads to unforeseeable power flows, which canaffect grid stability.

Furthermore, theliberalisation of the electricity market in Indiahas led to an increase in electricity trading.Short-term trading activities and the associatedtransmission of electricity over long distancesrepresent an additional challenge for the grid.

Due to numerous small-scalegenerating plants, upsurge in dependencyon electricity and increasing demand ofelectricity, power system has become intricateand is becoming complex day by day. Limitationsof space for electrical installations, rights of wayconstraints for new line routes, environmentalconcerns; all demand newer and more advancedalternatives to more effectively manages thepower supply system. Due to the nature of the changes, the grid needsto be partially reinvented and automated.

Gridintelligence and communication is required forgrid operation to meet the requirements of thetransforming energy sector. Nevertheless, datameasurements from various places and variouslevels in the grid are necessary to enable theutilities to monitor everything that happens on areal time basis (or to start with, on a daily, hourlyor quarterly basis).

A supervisory and control system that aims to deliver not only operability, reliability and maintainability, but also cost-effectiveness, while at the same time enabling labour savings in operation and maintenance. The new system has been applied to a state-of-the-art coal based thermal power station and combined-cycle power station. Through enhanced interlock, expanded automation, on-site supervisory robots and other technological innovations, the system has enabled integrated operation from the central control room and labour savings. In addition, implementation of protective functions by printed circuit board, software configured alarm system and common sensor system, the system is not only highly reliable and easy to maintain, but also economical.

On-site start up operations and commercial operations results has confirmed the effectiveness of these features.

SCADA is a centralized system used to supervise a complete plant and basically consists of data accessing features and controlling processes remotely. It will help to improve the overall performance and efficiency of power station and enhance useful life.

In the generation segment, automation is mainly carried out for improving power plant efficiency, reducing operations and maintenance costs, lowering unplanned outages and extending the operational life of assets. While generation utilities have been deploying control and monitoring systems, network communication, etc., for the past few years, new digital technologies such as IoT, cloud-based platforms, advanced analysis, predictive data analysis, asset performance management software and intelligent forecasting solutions are gradually growing in the segment. Also, with the growth of digital technologies in the generation segment, the complete remote operation of power plant has become a reality.

Automation in Transmission: Digitalisation and automation solutions have been steadily growing in the transmission segment too. In recent years, substation automation has emerged as a key growing technology among transmission utilities. In Transmission segment, there is continuous advancement of transmission equipments with the application of digitlization and automation and make it suitable for smart grid operation and that is more compact, reliable, environment friendly || February 2022 ||

effectively and swiftly,improving the energy services.

Digital devices are at the core of smart power distribution.

They give facility and maintenance personnel visibility into the electrical network by measuring and collecting data, as well as providing control functions. Smart meters, intelligent electronic devices, IoT sensors, and control and automation software are critical components of digital solutions. Intelligent substations and smart transformers that can be controlled in real time are key emerging digital solutions. These solutions deploy intelligent switchgear, which can connect with the internet and provide comprehensive monitoring and protection as well as measure all electrical parameters in real time to ensure remote monitoring.

Operations and maintenance teams need to respond to risks as quickly as possible to avoid the possibility of facility downtime or damage to equipment. Intelligent devices and digitization deliver the data and alarm notifications they need to stay on top of conditions, as well as remote control capabilities to help them act faster when a potential problem arises. In addition, monitoring environmental conditions can help predict operating performance and, in turn, better optimize maintenance schedules and extend the lifespan of the power distribution equipment.

Rapid network expansion has rendered the management of grid operations much more complex. In the future, electric power systems will be characterised by bidirectional flows as the world adopts more renewable sources of energy and microgrid or nanogrid models. In such a scenario, automation of substations has gained significance because utilities want to be able to remotely monitor, operate and control their assets to improve system stability, efficiency, security and control. Substation automation involves the integration of the protection, control and data acquisition functions into a minimum number of platforms by eliminating redundant equipment and databases, thereby reducing capital and operational costs, and panel and control room space requirements.

Automation in Generation: Automation is a key emerging trend in the power sector that is picking up pace in a big way. Digital technologies allow devices across the grid to communicate and provide useful data for the management and operation of generation, transmission and distribution systems. Smart meters, internet of things (IoT) based sensors, network remote control and automation systems, and digital platforms help in real-time operation of the network and its connected resources.

and requires minimum installation and commissioning time.

Moreover, as the pace of renewable energy integration increases and there is widespread adoption of smart grid technologies, utilities would be required to increase the deployment of intelligent equipments or to undertake modifications to transform the existing modules into smart equipments as the availability of real-time data is critical in the context of both developments. In times to come, space challenges in transmission are also bound to get more acute. Hence, going ahead, equipment manufacturers need to undertake innovations and more towards smaller but smarter equipments. As a result, there is a need for more sophisticated operation and control to keep pace with the increase in supervisory and operational control in the segment of power generation, transmission, distribution.

Power Grid has emerged as a leader in technology adoption in substation automation, with state utilities following suit. Powergrid is undertaking remote operation of several sub-stations from its National Transmission Asset Management Centre in Manesar, Haryana, which was commissioned in April’ 2015. Powergrid is also implementing the wide area measurement system technology across India under its flagship Unified Real Time Dynamic State

ELECTRICAL MIR ROR

|| February 2022 ||

Measurement project. Digital substations, centred on the IEC 61850 protocol, are the next step in substation modernization.

Digital sub-stations comprise smart primary devices and intelligent electronic devices to achieve information sharing and interoperability. Powergrid has implemented pilot digital substation projects at Bhiwandi and Neemrana. Based on the experience from these pilots, the company plans to launch similar new projects.

Other emerging technologies include Flexible AC Transmission System (FACTS), which incorporate power electronics based static controller to enhance control and power transferability of the system. Powergrid is installing FACTS devices such as static VAR compensators (SVCs) and static synchronous condensers (STATCOMs) in the interstate transmission system grid. It has already commissioned one SVC in Jammu & Kashmir and four STATCOMs. Further, 11 STATCOMs are at various stages of implementation.

Automation in distribution: Automation and digitization helps discoms in the judicious utilization of funds. There are certain spare capacities in the distribution network and maintaining these entails additional expenses, which are eventually passed on to consumers. Digitalisation provides tools that help in ||www.electricalmirror.net||

managing these spare capacities by optimizing network design and performance. Further, through digitization, thefts can be pinpointed accurately, thereby assisting the discom in controlling electricity losses due to theft.

One of there as on for high AT&C losses of discom has been the low level of billing and collection efficiency, which translate into lower revenues and thus broader loss margins. Low collection efficiency can be attributed to limited collection facilities, delayed delivery of bills, limited payment avenues and lack of trained manpower etc. Factors such as defective meters, unmetered connections, rampant electricity theft, overload transformers and inaccuracies in billing software contribute to the low billing efficiency of discoms. To mitigate these issues, the discoms have been encouraging digital payments such by launching mobile applications or web portal for billing purpose.

Utilities have taken several efforts on the digitization of metering front in order to mitigate the problems of high AT&C losses and power theft. A range of electronic and digital meters are being deployed by utilities to replace old manual meters. Further, the utilities are installing smart meters to identify and reduce instances of energy theft more efficiently. The growth of net metering policies across ||www.electricalmirror.net||

states has given an opportunity to consumers to become prosumers by feeding electricity generated from roof top solar photovoltaic panels installed on their premises back to the grid. With this, the distribution grid has become more active as power is flowing in both directions and utilities need technologies to monitor and manage the flow of electricity in real time. In addition, advanced load forecasting technologies are required to deal with the changing load profile as customers become less dependent on central generation to meet their electricity demand.

Smart Grid Technology A smart grid is an electrical grid which includes a variety of operational and energy measures including smart meters, smart appliances, renewable energy resources, and energy efficient resources. Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid. To ensure a seamless transition from existing approach to Smart Grid scenario, focus of any utility must be structured around four key priorities. These are Empower Customers to better manage and control their electricity use, Improve Reliability, Maintain Privacy and Security and Support Renewable integration and economic development. The government has taken a number of steps towards making the grid smarter. In the distribution segment, technology initiatives are being taken under the ministry of power approved pilot projects as well as National Smart Grid Mission. The functionalities being tested in these pilots include advanced metering infrastructure, outage management system, peak load management, power quality management and distributed generation.

In order to address the above-mentioned priorities, Smart Grid technologies need to be implemented in conjunction with the existing application/technology. Smart grid generally refers to a class of technology that is being considered to bring paradigm shift in power distribution utility’s performance.

The Smart Grid represents an unprecedented opportunity to move the energy industry into a new era of reliability, availability, and efficiency that will contribute to economic and environmental health. The benefits associated with the Smart Grid are more efficient transmission of electricity, quicker restoration of electricity after power disturbances, reduced operations and management costs for utilities, and ultimately lower power costs for consumers, reduced peak demand, which will also help lower electricity rates, increased integration of large-scale renewable energy systems and Improved security || February 2022 ||

Intelligent Automation In Substation Automation System, the various quantities (e.g., voltage,current, switch status, temperature, and oil level)of various equipment are recorded, using a dataacquisition device called Intelligence ElectronicDevices (IED). IED can establish communicationbetween remote sensors and controllers and thecommunications network.

Asingle IED can control several different aspects of a pieceof equipment so that the entire piece ofequipment works in harmony with the rest of theneeds of the system and within establisheddesign parameters.

Automation is based on the principle of converting all inputs and outputs into digital forms. The automation system can be designed anddeveloped using information technology/embedded systems and integrating the sameinto the existing grid substation.Components such as computers, Remote TerminalUnits (RTUs), actuator control of motorizedvalves, breakers, switched capacitor banks,on-load tap changing transformers, load break/make switches, auto re-closures, sectionalizes, and communication systems can be integratedinto the automation system. Integration withAutomated Mapping and Geographical Information System (GIS) Software packages iswidely used at present.

IEDs receive datafrom sensors and power equipment, and canissue control commands, such as tripping circuitbreakers if they sense voltage, current, orfrequency anomalies, or raise/ lower voltagelevels in order to maintain the desired level.

These systemquantities are transmitted on-line to the remotecontrol room through a variety of communicationmedia. The measured field data are processed inthe control room for display of any operatorselected system quantity through Graphic UserInterface. Any control action (for opening orclosing of the switch or circuit breaker) is initiatedby the operator and transmitted from the remote-control room through the communication channelto the RTU associated with the correspondingswitch or circuit breaker.

The desired switchingaction then takes place and the action isacknowledged back to operator for information. Substation Automation is dedicated to the monitoring andprotection of the critical equipment of asubstation and its associated lines or feeders andalso generates MIS data, reports and graphs etcfrom remote control centre.

Key Benefits of Automation Automation provides tools that help in optimizing network design and performance. Further, through automation, thefts can be pinpointed accurately, thereby assisting the

ELECTRICAL MIR ROR

|| February 2022 ||

utilities in controlling losses due to theft. Automation and digitalization also extend to associated services as well these include inventory management, asset management, maintenance strategies and monitoring of asset health.

The implementation of enterprise resource planning (ERP) solutions has helped in effectively managing its inventory with better measurement and control of the inventory. It provides significant information about various consumer parameters to the utility which could be used to provide other services.

Substation automation involves the integration of operationsrelated activities like system protection, control and data acquisition into a unified control system. The objective of automating substations is to reduce overall costs and eliminate redundant equipment and database by minimising human intervention. A unified control system in an automated substation includes control of substation systems from one place, comprehensive protection management, compact system designs, decentralized system structure, no conventional mimic board, numerical protection and control, self-interlocking and supervision, modern man-machine interface, operator guidance and maintenance support.

Substation automation also refers to using data from intelligent electronic devices control &automation capabilities within the substation and control commands from remote users to control power system devices.Substation automation makes a smarter and morereliable power grid.

There are many other benefits associated with an automated substation. These include less use of hardware and panels, reduced operating & maintenance cost, minimum outages, integration of third-party equipment, lower cabling and installation costs, reduced testing and commissioning costs, less space and civil works requirement, easy customization and use, operational efficiency with minimum errors, lower risk, and better power quality.

Challenges: Developed countries have already automatedtheir complete power supply system and theirgrids are remotely controlled.

On the other hand, even after having edge in IT skill, India is waybehind in automation. What to talk of existinggrid network automation, even the new grids (especially, by states) are being constructed withold and outdated technology without anyintervention of automation. Centre Government’sinitiative of providing funds for automation &improvement under schemes are eitherunutilized or are invested haphazardly in IT thatresulted in issues such as: ||www.electricalmirror.net||

• Stand-alone systems-Coverage to limited geographical areas • Inadequate interface and integration withother applications • Absence of a standard architecture • High cost of maintenance • Basic operations are still manual withoutinbuilt controls

These issues have adversely affected thereturns from IT investments. Incoherenttechnology strategy leads to situations whereincompatible options are selected and large sumsof money are wasted in attempts to integratethem. The bottom line is that the businessperformance has not improved.

Evidently, fundamental changes are requiredin the working of the power sector entities.Information Technology (IT) would become thekey enabler in the initiatives under the reformprocess initiated by Government of India. Thiswill enable substantial improvement in theoverall health of the utilities.

Cyber security is also one of the key threats of automation and digitization. Apart from this, ensuring consumer privacy is extremely important. Consumer data needs to be protected not only from economic point of view, but also from the security point of view. A household’s electricity consumption data can be used to determine how many people are living in the house at a particular point of time. If this data become publicly available, it can pose a serious security

ELECTRICAL MIR ROR

|| February 2022 ||

risk to the consumer.

Another critical issue with the automation is the inability to efficiently extract the required information from the system, owing to the large quantity of data originating from IEDs. Different devices store data in different formats, such as waveform samples or event reports, which are not easy to compare. Communication networks comprise lower-level data links, as well as physical layer and multiple application layer protocols.

Conclusion: Automation involves reskilling existing workers, redeploying others to new tasks and retooling potential workers who are students in university. Furthermore, the concept of “smart” work and demand for specific skills will encourage universities to redesign higher education and training and finally facilitate job-market transition. It is important to differentiate between automation potential and automation adoption. While a high number of tasks might be technically automatable, the adoption of particular technologies will depend on a complex interplay of factors including the cost of labour, levels of education and skilling, legal frameworks for innovation, labour protection policies, availability of supporting infrastructure and social and cultural norms that shape attitudes towards technological change and innovation.

With the government announcing various schemes and incentives, “Make in India” concept will definitely take India to a higher platform. RM

||www.electricalmirror.net||

The hydro power segment has long been facing challenges that have hampered its growth Hydro power projects are generally categorized in two segments i.e. small and large hydro. In India, hydro projects up to 25 MW station capacities have been categorized as Small Hydro Power (SHP) projects. While Ministry of Power, Government of India is responsible for large hydro projects, the mandate for the small hydro power (up to 25 MW) is given to Ministry of New and Renewable Energy.

Over the years, there has been a significant improvement in the load balancing and peak load management ability of the power system, with the integration of the regional grids and the streamlining of network frequencies. However the country has inadequate peaking capacity with quick response characteristics. This is critical in the context of large-scale renewable energy capacity coming in the next few years. Hydropower projects with quick start and zero load operation capabilities are ideal for meeting peak load and balancing needs.

The country’s total installed hydropower capacity stood at 45400 MW as of January’ 2021, representing only 30 per cent of the estimated potential (around 150 GW) and only 13 per cent of the total installed power generation capacity. Further, projects aggregating 11 GW are currently under execution. Beside, being a clean source of energy, hydro power is one of the preferred technologies for managing variability in the grid with its easy and quick start-up capability. Now, with the increasing share

||www.electricalmirror.net||

of renewable in the power generation mix, there is an even greater need for hydro capacity. The government is already taking steps to fast-track growth in the segment, including bringing out a new hydropower policy, reassessing the hydro potential and identifying cheaper sources of finance.

Out of hydropower installed capacity as on January’ 2021, the state sector accounts for the majority share of 67 percent, followed by the central and private sectors at 26 per cent and 7 per cent respectively. About 59 percent of the capacity is in the form of storage-based plants and 22 per cent lies in run-of-the-river plants. The remaining capacity is installed as run-of-the-river with pondage. Over the last five years, the installed hydropower capacity has grown at a compounded annual growth rate of only 3 percent. The highest year-on-year growth was witnessed in 2020-21 as the capacity increased by almost 4 per cent.

However, the share of hydro power in the total installed capacity has been declining consistently, from 17.7 per cent in March’ 2021 to 13.50 percent in March’ 2019. This is because of significantly low capacity addition in the segment as compared to the growth in the country’s total installed capacity during this period. For the past many years, the capacity addition has not been in line with the targets. While actual capacity addition in FY2016-17 was 37.5 per cent less than the target, it was underachieved by only 1.1 percent in 2020-21. The capacity addition has also

missed the overall target for the Twelfth five year plan period ended March’ 2017. Against the targeted addition of 10.9 GW during 2016-21, the actual achievement was around 5.5 GW. Small Hydro Power Small Hydro Power (SHP) plants have many advantages over large scale hydropower generation. SHP has been identified as a good alternative to conventional electricity generation for many developing countries around the world. Run-of-the river type SHP plants contain considerable economic advantages. However these are affected by various technical and economic challenges. An estimated potential of about 20,000 MW of small hydro power projects exists in India. Ministry of New and Renewable Energy has created a database of potential sites of small hydro and 6,474 potential sites with an aggregate capacity of 19,750 MW for projects up to 25 MW capacity have been identified.

Ministry of New and Renewable Energy has been vested with the responsibility of developing Small Hydro Power (SHP) projects up to 25 MW station capacities. The estimated potential for power generation in the country from such plants is about 20,000 MW. Most of the potential is in Himalayan States as river-based projects and in other States on irrigation canals. The SHP programme is now essentially private investment driven. Projects are normally economically viable and private sector is showing lot of interest in investing in SHP projects. The viability of these projects improves with increase in the project capacity. The government aim to harness at least 50 of the potential in the country in the next 10 years. The focus of the small hydro project programme is to lower the cost of equipment, increase its reliability and set up projects in areas which give the maximum advantage in terms of capacity utilization.

Pump Storage Project: Pump storage hydropower is one of the most developed and reliable energy storage technologies globally. With an increase in the country’s intermittent renewable energy capacity, pumped storage plants have assumed further importance as they enable energy storage through their large reservoirs. These plants help

ELECTRICAL MIR ROR

|| February 2022 ||

in load balancing by pumping water to the upper reservoir during times of surplus power in the grid and running in generating mode during times of deficit power. Apart from offering critical ancillary grid services such as voltage support and grid stability, they help in improving the capacity utilization of thermal, solar and wind stations.

Currently, the country has nine pump storage plant with a total installed capacity of 4,786 MW, which is almost 11 percent of the cumulative installed hydropower capacity. The first pump storage plant was the 706 MW Nagarjuna plant, which was commissioned during the period 1980-85. It is, however, currently not operating in pumping mode since the tail pool dam is not functional. Out of the nine projects, only five plants with an aggregate capacity of 2600 MW are working in pumping mode. These plants are 400 MW Kadamparai, 150MW Bhira, 900 MW Srisailam left bank power house, 250 MW Ghatgar and 900 MW Purulia. The 240 MW Kadana Stage I and Stage II plant in Gujarat is facing vibration issues, while the 40 MW Panchet Hill plant has been facing land acquisition concerns in the lower reservoir. It is a similar case with the 1200 MW Sardar Sarovar project in Gujarat, where the tail pool dam is under construction.

The Central Electricity Authority has identified a potential of 96,524 MW across 63 sites for pumped-hydro schemes on main rivers and their tributaries. As per the estimation, the western region has the highest potential for the development of pump storage plants with Maharashtra alone having a probable installed capacity of 27,094 MW. The southern and north-eastern regions, with a potential of 17,750 MW and 16,900 MW respectively, hold enormous opportunities for hydropower development. Meanwhile, the pump storage plant potential of the northern region stands at 13,065 MW and that of the eastern region at 9,126 MW. Two pump storage plants aggregating 1080 MW are under construction in Tehri, Uttrakhand 1000 MW and Koyna Left Bank, Maharashtra 80 MW. Both these projects are expected to be commissioned by end of 2019. Several other projects aggregating over 9,430 MW are at pre-development stages. ||www.electricalmirror.net||

||www.electricalmirror.net||

State specific issues Hydro potential rich states such as Arunachal Pradesh and Sikkim have not been able to effectively harness their hydropower potential. In Arunachal Pradesh, this has been primarily because of the anti-dam protests by environmentalists and locals, rehabilitation issues, and interstate and cross border disputes regarding water sharing. Recently, the Siang Indigenous Farmers’ Forum opposed the construction of a 10, 000 MW hydropower project over thy river, citing displacement of the tribal communities in the area. In Sikkim, the main issues being faced in the development of hydropower projects are delays in land acquisition and environmental and forest clearances.

Further, since the state lies in a severe seismic intensity zone, it is prone to earthquakes and natural calamities, which have led to damage of Hydropower projects construction sites in the past.

Geological surprises have impacted the construction of hydropower projects in the Uttarakhand, Himachal Pradesh and Jammu Kashmir as well. In Uttarakhand, the Supreme Court had revoked clearances of 24 out of 70 projects planned in the AlaknandaBhagirathi river basins after the 2013 floods, citing direct and indirect impact of the projects on the river flow. Meanwhile, in Jammu and Kashmir, adverse law and order conditions hamper project activities. Thus, intervention from the state government is required to ensure security in order to attract investors and fast track the development of the projects. Besides, the water sharing dispute amoung states is a key challenge. Since water is categorized as a state subject, consent from all states affected by the hydropower project is required. Projects that have been facing delays on account of water sharing disputes include the 975 MW In champalli hydropower project in Andhra Pradesh, the 60 MW Karbi Langpi hydropower project in Assam, 480 MW Cauvery hydropower project in Tamil Nadu, the 150 MW Bhavani hydro power project in Kerla, and the 320 MW Sindol hydropower project in Odisha. In view of the increasing power demand and need for a viable energy storage technologies, the state governments need to fast-track their stalled hydropower projects and work in association with all stakeholders to effectively harness hydropower.

Conclusion: Slowdown in capacity addition has been a major challenge for the segment. Hydro power capacity addition in the past five years, much lower than thermal and other renewable addition.

This has also resulted in a decline in the hydro-thermal ratio of 40:60 from the system availability and reliability point of view. The current hydro-thermal ratio stands at about 17:83, indicating the lack of flexible generation required to meet the peak demand. Flexible hydropower generation assumes even greater importance now with the increasing share of intermittent renewable generation. Over the past five years, the hydropower segment has recorded limited growth. With adequate policy and regulatory support, hydropower projects can go a long way in reducing the regional disparities in power supply and alleviating the sector distress. RM || February 2022 ||

w w w. e l e c t r i c a l m i r r o r. n e t

Certain regulatory challenges such as the lack of a separate peak pricing regulation have hampered the development of pump storage plants in the past. Since these projects use energy for pumping operation, the pricing of the energy produced by pump storage plants during peak hours needs to be justified on commercial principles. The regulatory framework for pump storage plants needs to take into account the benefits of energy storage, grid balancing and voltage support provided by these projects.

Issues and challenges: The hydro power segment has long been facing challenges that have hampered its growth in the country. These include environmental issues pertaining to delays in forest and wildlife clearances, public hearing processes and land acquisition, rehabilitation and resettlement, and stringent environmental norms. Infrastructural issues such as the inaccessibility, law and order issues, interstate water sharing disputes, and technical issues such as lack of competent contractors and skilled manpower.

Further, limited finances are available for hydro projects due to low returns, high capital costs and the long gestation period involved in the development of hydro power projects. These issues results in considerable cost and time overruns for hydropower projects which in turn result in higher tariffs, making these projects financially unviable.

Delay in project execution Delays have become commonplace in the hydropower sector due to land acquisition challenges, long gestation periods and R&R issues. However, the biggest impediment to project commissioning remains the multitude of clearances and approvals required.

In addition, weather fluctuations often slow down the pace of work thereby aggravating the problem. Further, rehabilitation concerns amongst local communities and subsequent agitations continue to act as roadblocks in the commissioning of hydropower projects. In addition, most new hydropower sites are located in remote hilly areas with little or no infrastructure facilities such as roads, thus making the transport of men and machinery difficult. Apart from these, issues pertaining to water sharing between states, geological factors and delays in the award of contracts have been responsible for commissioning delays, which have exceeded 5 to 10 years in some cases.

Due to the cost-intensive nature of hydropower projects and unanticipated contingencies, the cost overrun of these projects is also significant. Since hydropower projects are financed by a huge amount of debt, project delays lead to significant cost escalation on account of the interest component of the loan.

The interest during construction is calculated till the time the project gets commissioned and starts generating revenue. The process of obtaining clearances from several authorities and various geological factors such as floods and landslides lead to delays in project commissioning, thereby increases the duration for which interest is calculated and the overall project cost.

Most hydropower projects under construction have experienced cost overruns with an average breach of about Rs. 18.5 billion.
