However, all is not so well within the sector especially in the power distribution front. It has been reported that the India’s average plant load factor (PLF) has dropped to a 15-year low of 65.1 per cent. Poor health of state electricity boards (SEBs) and lack of coordination between states-centre authorities are the major contributors for such debacle. If we need to address the issues like downfall of PLF, the government has to bring total reforms within the power sector.

Solar power capacity target raised 5 fold to 100 GW The Union Cabinet, chaired by the Prime Minister Narendra Modi, gave its approval for stepping up of India’s solar power capacity target under the Jawaharlal Nehru National Solar Mission (JNNSM) by five times, reaching 1,00,000 MW by 2022.

and reduce dependence on fossil fuels that put a strain on foreign reserves and the ecology as well. The solar manufacturing sector will get a boost with this long-term trajectory of solar capacity addition.

This will help in creation of technology hubs for manufacturing. The increased manufacturing capacity and installation are expected to pave way for direct and indirect employment opportunities in both the skilled and unskilled sector.

The target will principally comprise of 40 GW Rooftop and 60 GW through large and medium scale grid connected solar power projects.

With this ambitious target, India will become one of the largest Green Energy producers in the world, surpassing several developed countries.

“The new solar target of 100 GW is expected to abate over 170 million tonnes of CO2 over its life cycle. This Solar Scale-up Plan has a target of 40 GW through decentralised solar power generation in the form of grid connected rooftop projects. While decentralised generation will stabilise the grid, it will minimise investment on power evacuation,” the statement said.

The target will require an investment of around ` 6,00,000 crore. In the first phase, the government will provide ` 15,050 crore as capital subsidy which would be utilised to develop rooftop solar projects, viability gap funding (VGF) based projects, and decentralised generation through small solar projects. The Ministry of New and Renewable Energy (MNRE) intends to achieve the target of 1,00,000 MW with targets under the three schemes of 19,200 MW.

ACME opens 100 MW solar power plant in Rajasthan

In addition, solar power projects with investment of about ` 90,000 crore would be developed using bundling mechanism with thermal power.

“Further investment will come from large Public Sector Undertakings (PSUs) and Independent Power Producers (IPPs). State governments have also come out with State specific solar policies to promote solar capacity addition,” an official statement said.

“The government may also approach bilateral and international donors as also the Green Climate Fund for achieving this target,” the statement adds.

Solar power can contribute to the long-term energy security of India,

Solar power producer ACME announced the commissioning of 100 MW solar power plant in Rajasthan.

The company has invested ` 800 crore for five projects form the cumulative projects of 100 MW.

SC upholds applicability of RPO on captive power plants The Supreme Court ruled that renewable purchase (RPO) obligations applicable to captive power consumers are justified. The order came in the case between Hindustan Zinc and Rajasthan Electricity Regulatory Commission.

The SC has ruled that RPO on captive consumer is justified and interpreted it in the context of Article 51A (g) of the Constitution of India that cast a fundamental duty on the citizen to protect and improve the natural environment, and the mandate of Article 21 that guarantee right to live with healthy life.

The Section 86 (1) (e) of the Electricity Act (EA) 2003 provides for RPO on consumption of energy and the RPOs are determined by respective State Electricity Regulatory Commissions. The applicability of RPOs is on the Distribution Companies (Discoms) Captive Power Plants (CPP) and also on Open Access (OA) consumers.

In August 2012, the Rajasthan High Court had dismissed an appeal

by Hindustan Zinc Ltd., Ambuja Cements Ltd., Grasim Industries Ltd., and 14 other companies that challenged RPO regulations enacted by the Rajasthan Electricity Regulatory Commission (RERC) for put RPOs on Captive Power Plants. The key Captive Power Plants and Open Access users had contested that RERC did not have the authority to pass the order of RPO and impose surcharge (penalty) as CPP and OA were completely de-licensed activities under the Electricity Act 2003.

Further that EA 2003 only allows RPO on the ‘total consumption in the area of the distribution licensee’ and therefore intends to apply RPO on distribution licensees only. The Hindustan Zinc had appealed in the Supreme Court against the High Court.

“The Supreme Court order is a positive development and will help in enhancing RPO compliance and further contribute to renewable energy growth in the country,” the Ministry of New and Renewable Energy said issuing a statement referring to the court’s order which came on May 13.

Hindustan Powerprojects Achieves COD of Unit-I of its Anuppur Thermal Power Plant The COD of unit-I (600 MW) of the first phase of 2,520 MW Anuppur thermal power project in Madhya Pradesh project has been commissioned at a total project cost of ` 8,000 crore. This project will play key role in addressing power sufficiency to UP and MP. The total capacity of this thermal plant is 2,520 MW to be developed in two phases of 1,200 MW (2 x 600 MW) 1,320 MW (2 x 660 MW).

Raghav Trivedi, President Thermal, said, “The company has pursued an inclusive agenda by reaching out to communities and adhering to the strictest environmental norms. The benefits of investing about ` 400 crore towards environment-friendly technology like ESP and planting over 81,000 trees will be reaped by the communities during the lifetime of the project. We thank the local authorities, community leaders and the people in the surrounding communities for their support. The commissioning is an evidence of the success of the PPP model.”

Sterlite commissions 765 kV transmission Adani to develop 10,000 MW solar park project in Rajasthan Sterlite Power Grid Ventures Limited (Sterlite Grid), a subsidiary of Pune-based Sterlite Technologies Limited, completed commissioning of all eight elements of Bhopal Dhule Transmission project. The project implemented by the special purpose vehicle Bhopal Dhule Transmission Company Limited (BDTCL) involves six transmission lines of about 1,000 circuit kilometres and the two 1,500 MVA substations at Dhule and Bhopal.

Adani Group has signed a joint venture agreement with the government of Rajasthan to set up a 10,000 MW solar park, which would emerge as the largest such integrated facility in India.

Sterlite Grid is the first private developer to commission 765 kV project in India under the ‘Build, Own, Operate and Maintain’ model. The project traversing through the states of Madhya Pradesh, Maharashtra and Gujarat will attract annual tariff of close to ` 250 crore. The fully commissioned project will contribute significantly to the cash flow of Sterlite Grid that will operate and maintain this project for 35 years. The project will benefit close to a million households in these states.

The proposed park is expected to attract investments over `60,000 crore and it will include generation projects and a massive manufacturing unit for solar module, parts and equipment. Adani itself plans to generate 5,000 MW in this solar park.

BDTCL project is part of the system strengthening scheme of the Western Region to facilitate the transfer of up to 5,000 MW of electricity from the coal belt in the East, to the energy deficient regions of western and northern India. It involves 765 kV Single Circuit Lines; Vadodara-Dhule-Aurangabad and Indore-Bhopal-Jabalpur, two 400 kV Double Circuit transmission lines and two 765/400 kV substations at Bhopal and Dhule to strengthen the transmission system in the states of Madhya Pradesh, Maharashtra and Gujarat.

BDTCL is considered as a critical part of national grid as it facilitates the evacuation of power from Odisha & Chhattisgarh to load centers.

This network will also provide energy stability to Indore, Dewas and Aurangabad among the other industrial pocket of the route.

The JV will be known as Adani Renewable Energy Park Rajasthan Ltd, will have a 50-50 equity partnership between the Rajasthan government and Adani Renewable Energy Park Ltd, a subsidiary of Adani Enterprises Ltd.

OPEN FORUM SC upholds applicability of RPO on captive power plants. What is your comment?

Positive impact is imminent What is clear is that the government has a clear intent to support the RPO and we’re seeing that in the various matters that are being adjudicated either at the regulatory level or at the court. I’m glad to see that this is happening. I think RPO is a very important construct of the growth of renewable in India. So I do believe that any verdict that supports the sanctity of RPO is definitely going to have an impact.

- Pashupathy Gopalan, President, SunEdison – Asia Pacific

A positive development The ruling will act as a major boost for the sector and will aid in casting the net wide to bring in mandatory consumption of renewable power by industries with captive power plants. Vikram Solar welcomes the apex court’s ruling as a positive development that will help all state electricity regulators implement RPO obligations more effectively.

A landmark judgment Presently, any obligated entity can comply with RPO either by setting up RE-based plants or purchasing RECs from the market. Not all obligated entities set up RE-based projects since it demands capital, land and grid infrastructure. There are very few cases of setting up of such projects under RPO obligations. Now, if we look at the trade volume of RECs being traded, those are just around 4 – 5 per cent and there is still huge difference between supplied RECs and their cleared volumes due to less demand for RECs. The basic reason behind this scenario is no penalties imposed on obligated entities so far on non-compliance with RPO percentages.

This was also one of the reasons why RPO after its introduction in the Electricity Act 2003 could not be the instrumental factor in promoting renewable energy in India. Hence, the judgment given by the Supreme Court has significance in context with the actual implementation of RPO and overall growth of RE sector.

- Gaurav Sood, Managing Director, Solairedirect Energy India

Much needed boost for RE sector The SC order provides clarity on applicability of RPO on captive entities that they have to procure green power or RECs becomes certain. The SERCs can now impose stricter RPO compliance measures as per their regulations.

With the reduction in the floor prices of the solar RECs and the huge availability of non-solar RECs that can sustain the market price to remain at floor price value for a considerable length of time, the obligated entities should have no more reasons to refrain from quarterly RPO compliance and participation in REC trading sessions.

Powering India Kshitija Kolhapure outlines the performance and future growth plans of Coal India power utilities of the country during 2014-15 surged ahead to 384.18 million tonnes, up by 30.35 million tonnes, from that of 353.83 million tonnes achieved in 2013-14 registering 8.5 per cent growth. Coal India has set an ambitious target of producing 550 million tonnes of coal during 2015-16.

Meeting India’s need In India, coal as an irreplaceable dominant energy fuel meets more than 50 per cent of primary commercial needs. Coal India alone meets around 40 per cent of the primary commercial requirements of the country. The gap between demand and supply is increasing annually. The country’s coal demand is racing ahead of the indigenous coal production. During 201415, while the country’s coal demand has been 787 million tonnes, the actual all India coal production was around 611 million tonnes (Provisional). For the year 2015-16, the country’s coal demand is projected at 910 million tonnes whereas the production is expected to be around 700 million tonnes.

Coal India was formed in 1975, after coal mine were nationalised with effect from 1st May 1973. Today, it is the world’s largest coal producer, with seven wholly owned coal producing subsidiaries and 1 mine planning and consultancy company spread over 8 states of India. Not only this, it also owns ‘Coal India Africana Limitada’, which is a mining company in Mozambique. In addition, it also owns 26 technical and management training institutes and 102 vocational training institutes.

Enhanced performance At its inception, Coal India started with a modest production of seventy-nine million tonnes. Now it produces over 400 million tonnes of coal annually. And dominates 74 per cent of the Indian coal market. In spite of facing challenges such as: land acquisition and greener clearance, Coal India in the FY 2014-15, improved its performance by 7 per cent. Coal India has put up a commendable performance in FY ending 2015 producing 494.23 million tonnes of coal registering 7 per cent growth. The production increase in absolute terms has been nearly 32 million tonnes compared to the previous fiscal which is highest ever incremental increase in a single financial year since the inception of the company.

In an aim to meet the ever increasing demand, Coal India is striving to increase its production capacity. The company has identified certain major issues, which would help enhance production. Seeing the timely completion of three major railway lines is priority short-term strategy, which would unlock large coal reserves in the states of Jharkhand, Chattisgarh and Odisha for evacuation. Another short-term measure is pursuing MDO (Mine Development Operators) process which would supplement coal production.

Technology nurturing To increase the production and meet the supply demand, in future, Coal India’s strategies would include productivity improvement in mines through Technology upgradation in opencast mines with induction of high capacity equipment and in underground mines with continuous miner technology in large scale, long wall technology at selected mines, man riding system in major mines and use of telemonitoring techniques. Other system improvements include e-procurement of equipment and spares, e-tender of works and services etc.

Ultimately Coal India’s aim is to meet the targets diligently.

Inefficient coal-based power plants are the major threats for our environment. This article highlights the Indian scenario and suggests how we can reduce emissions from such plants Huge air emissions from a stack of an Indian coal based plant Credit: Green rating Project, CSE, New Delhi

How to reduce emissions in coal-based power plants Of the total pollution from the industrial sector, the coal-based power sector currently accounts for approximately 60 per cent of particulate emissions, 45-50 per cent of sulphur dioxide (SO2) emissions, 30 per cent of nitrogen oxide (NOx) emissions and more than 80 per cent of mercury emissions.

Earlier this year, CSE had released its environmental rating of the coal-based thermal power sector, under its Green Rating Project. 47 plants – adding up to 55 per cent of the nation’s capacity – were rated ‘poor’ on all the parameters.

Kyoto Protocol ‘episode’ Over 100 developing countries, including China and India, were exempted from the Kyoto Protocol. So the question is: Did exemption from Kyoto Protocol backfired India in reducing the CO2 emissions?

According to Kishor Kumar Bhardwaj, Head – EHS, Hindustan Power Projects Pvt Ltd, “India and China both have ratified the Kyoto Protocol. However, India and China are in the list of developing countries. And countries in this list have no target assigned for GHGs reductions.

So, I don’t think exemption to reduce

GHGs emissions under Kyoto Protocol backfire India in reducing CO2 emissions.”

but with the improvement in combustion technologies, emissions can be reduced.

Sharing his comments on the same topic, Sanjeev K. Kanchan, Deputy Programme Manager, Sustainable IndustrialisationGRP, Centre for Science and Environment said, “As a developing country, India did not need to commit itself to any national emission reduction targets under the Kyoto Protocol. Per capita CO2 emission in India is 1.8 tonnes, far below of OECD (10.61 tonnes) and world average (4.39 tonnes). Even by 2031, it would remain below today’s world average. Therefore, India’s voluntary commitment to reduce the emissions intensity of its GDP by 20 – 25 per cent by 2020 (comparison to the 2005 level) is an important contribution to the global effort to mitigate climate change.”

Compared to the CO2 emission rate in an advance power plant (ultra-super critical) at 0.67tCO2/MWh power generation, average CO2 emission by an Indian plant is nearly double. The reason is our fleet of coal–based power plant which has major proportion of smaller, outdated and inefficient plants. A less efficient plant consumes more fuel for power generation which in-turn generates more CO2. Around 95 per cent of coal-based power generation capacity in India still operates on inefficient subcritical technology.

India and adoption of advanced technologies India still is lagging back when it comes to modernising thermal power plants and reduce the coal usage per unit of electricity generation (kg/kWh). Modernisation with reduction in coal usage (kg/kWh) will help in reducing the national emissions.

Quality of Indian coal will remain same

CCS in India is still not out from laboratory scale and there is no concrete success has made in this direction.

Sanjeev K. Kanchan, Deputy Programme Manager, Sustainable Industrialisation-GRP, Centre for Science and Environment

Electrical & Power Review

Feature For example, Japan started running advanced ultra-supercritical plants 15 years back, which led it to be the country with one of the highest efficient power sector, above 40 per cent efficiency, in the world plant. Even after 15 years, India doesn’t have any ultra-supercritical plant till, and therefore, the efficiency of Indian plant is one of the lowest, around 33 per cent.

Therefore, India needs to bring in the advanced power plant (ultra-super critical) to reduce the CO2 emission. Mr Kanchan thinks, “It indicates, we have the biggest opportunity to control over GHG emission through improvement in this sector. What we are supposed to do is to phase out the in-efficient plants and modernise those which have scope of improvements. Where the older plants need to improve, the new and upcoming ones need to be ensured for having efficient and clean technologies.”

Thus, if India adopts the advanced power plants, have huge scope of improvement in energy efficiency, therefore in CO2 emission reduction as well. One can imagine the scope of improvement with the fact that, if we improve the efficiency by 3.5 per cent, our CO2 emission can reduce by 9 per cent. Even if a 300 MW plant improves its efficiency by 1 per cent, it can save 1 million tonnes CO2 over its life of 25 years.

Carbon capture, use and storage Carbon capture and storage (CCS) involves capturing carbon dioxide from the flue gas of fossil power plants and

long-term sequestration/storage. CCS is being considered worldwide as the key options for climate change response. Now the question arises: Is near-zero emissions from coal with carbon capture, use and storage (CCUS) possible?

Research (IGCAR) for enhanced efficiency of thermal generation. The objective of the scheme is to achieve higher efficiency, reduce carbon-dioxide emissions and reduce coal consumption for coal based power plants.

According to Mr Bhardwaj, “CCS has been identified by the IPCC as one of the key technologies in global efforts to stabilise CO2 concentrations at 450 or 550 ppm.

Widespread adoption of CCS has the potential of reducing fossil fuel emissions by 85 per cent or more by 2050.”

Regulatory push With the aim of tightening pollution norms for coal-based power plants in the country, the environment ministry has proposed a fresh standard for old and new units seeking them to substantially cut down release of dangerous particulate matter (PM).

To see on the other side, capturing the emitted CO2 and storing it has been observed in some countries but not widely. And as far as use of captured CO2 is concerned, it is still in the research and development phase. Even the carbon capture and storage CCS is very costly and has significant drawbacks like uncertainty over potential storage capacity, possibilities for leakage, increased public resistance and energy costs etc. Adding to it, CCS impacts hard on energy efficiency of the plant, reduces efficiency by 7-13 percent, therefore the power generation required to compliment that much power in-turn will emit additional CO2.

Mr Kanchan, said, “CCS in India is still not out from laboratory scale and there is no concrete success has made in this direction.”

Available technologies India needs high efficiency combustion technologies such as super critical and ultra-super-critical plants equipped with advance pollution control equipment.

Efficient combustion technology not only reduces CO2 emission, it also helps to reduce emission of nitrogen oxides, generated during in-efficient combustion process, which has significant impact on climate change. High-end technology also allows installation of better pollution control measures.

Off late, an Advanced Ultra Super Critical Technology R&D Project has been approved by the Indian government at a cost of `1,500 crore involving BHEL, NTPC and Indira Gandhi Centre for Atomic

India currently has no standards for SO2, NOx and mercury emissions from this sector. As the impact of pollution from coal-based power generation is known to be disproportionately high, the environment ministry proposed to tighten norms for emissions of PM, SO2, NOx and mercury and cut water use by coal-based thermal power plants.

However, there are currently no standards to curb emissions of SO2, NOx and mercury. The only standards that exist are for PM, which are quite lax compared with the global norms.

This fact was highlighted by finance minister Arun Jaitley in his budget speech in support of an additional cess of ` 100 per tonne on coal that will be used to invest in clean generation.

Proposed standards The new standards will be expected to cut particulate emissions from new plants by 25 per cent; SO2 emissions by 90 per cent; NOx emissions by 70 per cent and mercury emissions by 75 per cent compared with the existing stateof-the-art plants. Those plants that were established after 2003 will need to meet slightly lower standards, while plants older than 2003 will be required to meet more relaxed norms. “We believe these lower standards are acceptable given technical and economic limitations in installing pollution control equipment in older units,” said Priyavrat Bhati, CSE’s Director for Green Ratings Project. july 2015

Industry Analysis

An analysis on whether India will become a super power in the nuclear power domain and how it will cope with the challenges

India: An emerging power in nuclear Nuclear power plant is a much spoken topic at this moment. Many controversies and debates are going around in consideration with nuclear projects, and its hazard to the environment. There’s a huge question mark, whether, will India be a successful country to meet its energy target from nuclear power plants, or will it turn out to be like Chernobyl or Fukushima?

However, experts believe, in the coming years nuclear will be the main source of electricity generation. According to the data published by Power Reactor Information System of International Atomic Energy Agency in 2014, India ranked 13th in terms of generation.

Speaking on the positive note, the country has set a goal, to double the nuclear power generation capacity to more than 10 GW over the next five years. In addition, to have adequate

26

nuclear fuel supply to the stations, India has entered into Inter-Governmental Agreements (IGA) with France, Russia, Kazakhastan, Uzbekistan and Canada.

In the near future, the nuclear power projects will be based on indigenous technologies with global cooperation.

There are four native nuclear power reactors are under construction which is to be completed by 2019. Two more indigenous 700 MW reactors are also expected to be completed by 2024.

The dark cloud over the nuclear power projects has not yet gone. In India, there is fierce opposition towards nuclear projects development: one of them is Jaitapur Nuclear Power Project (JNPP). In spite of facing oppositions, protestors and anti-nuclear activist, the government continued its effort to boost the nuclear projects in India.

Recently, signing Agreement took place on 10th April 2015 for JNPP. If build, it would be the largest nuclear power generating station in the world by net electrical power rating.

However, the question remains: Is nuclear power a boon to India? Let us

India impressively developed indigenous core competence in the nuclear power sector.

David Durham, Senior Vice President, COO, GE Hitachi Nuclear Energy

Electrical & Power Review

Industry Analysis have a glance on what our industry expert have to say about the surge of the nuclear power in India.

Nuclear or renewable?

In December 2014, an open letter signed by 75 leading conservation scientists called for the environmental community to accept nuclear power as a key part of the global energy mix. It observed that the practice of generating energy out of nuclear power plant is in active process in many countries. Experts have expressed after a thorough study, that the nuclear power can offer reliable production for 24/7 and it will have lesser effect on the environment as it does not release harmful gases such as CO2 and methane.

The scientists also noticed that there is a very strong direct correlation between Human Development Index (HDI) and per capita electricity consumption. As nations, India included, endeavour to raise the standard of living, and will increase electricity generation. At the same time, climate change concerns demand that there is need to move towards cleaner forms of energy. Also, it is necessary to mention that electricity demand is increasing twice as fast as overall energy use and is likely to rise by more than two-thirds between 2011 and 2035.

Giving his expert opinion Shah Nawaz Ahmad, Senior Adviser India, Middle East and South-East Asia, World Nuclear Association, says, “Given the present scenario and severe need for electricity,

The Indian nuclear power track record, both of DAE/ NPCIL and the industry, bodes well for the success of this assimilation but it remains a challenge nevertheless.

in the near and intermediate term, most countries will need to have a power mix, which will need to include fossil fuels, renewables and nuclear. In the long term, fossil fuels will need to be eased out and greater share has to be taken by renewables and nuclear. India is also following this route, the debate is how much of which.”

It is very true that no country will generate energy from one source, it is essential to have various sources. In that case it is important to follow pragmatic route of power mix where one will see that renewables and nuclear stand on the same side of the carbon divide. Just like renewable, nuclear power is low carbon-generation source of power.

The biggest advantage from the nuclear power plant is that, it can deliver its performance in spite of harsh weather conditions. Parikh Shamik, General Manager, Marketing and Strategy, AREVA India, explains merits of nuclear energy over renewable by commenting, “The challenge with renewables is they are difficult to integrate on to a grid and also it is tough to forecast their output.

Nuclear energy can be produced from nuclear power plants, even in the cases of rough weather conditions unlike wind and solar plants. They can produce power 24/7 with high reliability, at very high efficiency, with low running costs, low fuel cost. The best part is that this energy has a continuous supply.”

David Durham, Senior Vice President, COO, GE Hitachi Nuclear Energy agrees upon the views expressed by Mr Parikh, saying, “Nuclear power produces more clean energy than all other sources combined. It is the only source that can produce large amounts of electricity around the clock and is not subject to changing weather or climate conditions.”

Talking about the cost advantages of nuclear power Mr Durham says, “As fuel accounts for just 31 per cent of a nuclear facility’s production costs compared to 80 or 90 per cent for coal or natural gas plants, nuclear power offers exceptional

price stability. In contrast, electricity from fossil-fuel plants is highly susceptible to fluctuations in coal and gas prices.

Looked at another way, one nuclear fuel pellet that weighs approximately seven grams provides as much energy as one ton of coal, 17,000 cubic feet of natural gas or 149 gallons of oil.”

Experts agree that, the nuclear energy is most efficient and reliable and 24/7 available. It can offer stable and reliable production. It seems that nuclear energy is receiving great support and will soon fix its position as one of the essential energy source. Sharing his experience of Finland, Pasi Tuohimaa, Head of Communications, Corporate Relations, Teollisuuden Voima Oyj, says, “Renewable energy sources depend on sunshine and wind. It does not shine at night and the wind does not always blow. Where do you get the energy from when renewables are out? At the moment renewable energy is much more expensive than nuclear energy and it needs a lot of taxpayers’ money.

Nuclear, not at least in Finland, needs no money from the taxpayers. I would say that nuclear energy together with renewables is a good combination for CO2 free world.”

Future of nuclear power in India There seems to be a steady way and support from the government to carry the nuclear deals, projects in spite of blockages. The nuclear capacity is poised to have steady growth of 12-14 per cent CAGR till 2030. India targets to reach 10 GW by 2019. The Indian nuclear bodies such as DAE and NPCIL are taking steps to develop the global bonds in terms of standards, ideas, new technology.

“The Manmohan-Bush deal opened the way for international nuclear commerce.

In addition to the Russian reactors, India proposes to build nuclear power plants with the cooperation of France and USA. The intention is that these additional plants will increase nuclear power manifold, helping India to meet its climate commitments to a certain degree, while providing much needed july 2015

electricity,” says Mr Ahmad. “The Indian nuclear power track record, both of DAE/ NPCIL and the industry, bodes well for the success of this assimilation but it remains a challenge nevertheless.”

Welcoming the initiatives taken by the government Mr Parikh says, “The current government is giving lot of focus to ensure improvement in all the areas of fuel supply, indigenous reactor technology, foreign collaboration as well as local supply chain development. So we will surely see a steady increase of nuclear power in India’s overall energy mix.”

Mr Durham believes that bringing the best technology to the country, advanced and passive safety-based reactors such as the GE Hitachi (GEH) ESBWR (Economic Simplified Boiling Water Reactor), would enable highly-skilled Indian engineers to become familiar with the technology.

He also adds that, “The U.S. Nuclear Regulatory Commission certified the ESBWR design last year and we expect to complete an early works agreement with NPCIL soon as we continue our collaboration on the site they have identified in the Kovvada region in Andhra Pradesh for multiple ESBWRs.” India post nuclear non-proliferation treaty India was out of nuclear nonproliferation treaty due to its weapon program for 34 years. Ironically, the years of isolation gave an impact on the collaboration and joint research that India could have done with other

countries. As a growing nation, though India faced this severe problem, it fought back the situation with determinations and got back on its feet. Mr Parikh says, “India has developed the sophisticated nuclear technology for PHWR, FBR and also AWR type reactors which clearly shows that these years of isolation have been used judiciously. India has also developed its own nuclear technology for military use making it one of the select nuclear-armed states.”

Over the years, India developed its own nuclear expertise and gained regards within the international fraternity.

Today, India has a long-standing, comprehensive and robust nuclear programme, which covers all aspects of the nuclear energy.

Currently, it is building several 700 MWe PHWRs and one 500 MWe FBR. This is an indigenous programme where Indian authorities have designed and constructed the reactors and operate the same. This programme is well under way.

According to Mr Durham, “India impressively developed indigenous core competence in the nuclear power sector.

This included the infrastructure to support servicing, refuelling, upgrading and regulating its reactor fleet. This infrastructure will help build, maintain and service the new reactors that are being planned.”

Nuclear safety issues Nuclear power is a critical solution to the global climate change challenge.

Reducing carbon emissions will require a diverse energy portfolio. Without clean, safe nuclear power, reaching carbon goals is all but impossible.

However, following the Fukushima nuclear accident of 11 March 2011, the authorities across the world got shaken up. The devastating accident caused by a 15-metre tsunami raised serious questions over the safety of nuclear power plants. Sharing his views Mr Parikh says, “Fukushima accident raised legitimate concerns and the nuclear

industry has responded to ensure that all the lessons in nuclear safety are learned from it. Post-Fukushima the international safety standards have been revised to ensure utmost safety even in extreme situations.”

However, despite Fukushima, the fundamentals of the nuclear market remain the same. “Fukushima accident does not call into question the growth of nuclear energy. The challenges remain the same: energy independence, growing demand for electricity, and climate change,” Mr Parikh adds.

Explaining the ever-increasing confidence in nuclear power Mr Ahmad shares, “Globally, before Fukushima accident, there were 434 reactors in operation, 72 under construction and 173 were planned. As of March 2015, 437 reactors are in operation, 65 are under construction, and another 165 reactors are planned. Nuclear continues to generate 11 per cent of the world’s electricity as before. Even in Japan, nuclear restarts are now being authorised.”

“From a technological standpoint, the industry has continued to evolve with each new generation of reactor bringing enhanced safety and efficiency. Today, this evolution culminates with GEH’s ESBWR,” Mr Durham explains. “With its advanced passive safety systems, the ESBWR is the world’s safest nuclear reactor design on the market today, based on the industry standard of core damage frequency. Additionally, the

At the moment renewable energy is much more expensive than nuclear energy and it needs a lot of taxpayers’ money.

reactor can cool itself for more than seven days with no on-site or offsite AC power or operator action in a station blackout situation. The ESBWR is unique among reactors in this capability.”

Recently, a 12-day long survey was carried out by International Regulatory Review Service (IRRS) Mission of International Atomic Energy Agency (IAEA) to review the Indian’s regulatory framework for nuclear safety. The Mission looked at the regulatory framework of AERB for nuclear power plants and projects.

The team identified a few areas of the Indian nuclear safety regulatory framework in need of improvement, including the following: • Promulgation of the established policies and strategy for safety and the strategies for radioactive waste management as statements of the government’s intent • Embedding in law the regulatory independence of AERB • Review of implementation of policy and arrangements to ensure maintenance of independence in the performance of regulatory functions • Enhancing then frequency of routine on-site inspections at NPPs to allow for additional independent verification • Development and implementation of its own internal emergency arrangements including detailed procedures to fulfil its roles related to emergency response.

“When we talk of waste, we need to talk both about the volume of waste, our ability to handle it and the ill effects of coming into contact with this waste,” Mr Ahmad said. The quantity of fuel needed to generate a certain amount of power depends on its calorific value and obviously if a lot of fuel is put, a lot of waste will be generated.

Typically, a 1000 MWe plant needs 2,000,000 tonnes of coal, or 1,960,000,000 gallons of oil, or 27 tonnes of uranium. A coal plant will generate, on an average 400,000 tonnes of ash, as well as considerable amounts of particulate matter and injurious elements such as As, Hg, Cr, Cd. In addition it will produce around 5,000,000 tonnes of CO2 per year.

Whereas a typical 1000 MWe light water reactor will generate 200-350 m3 low- and intermediate-level waste per year. It will also discharge about 20 m3 (27 tonnes) of used fuel per year which corresponds to a 75 m3 disposal volume following encapsulation if it is treated as waste. Where that used fuel is reprocessed, only 3 m3 of vitrified waste (glass) is produced, which is equivalent to a 28 m3 disposal volume following placement in a disposal canister. Safe and secure storage of these much smaller quantities, over a long period of time is now considered feasible and practical. “India has adopted the reprocessing route so the lower volumes will govern in the country,” Mr Ahmad adds.

Mr Passi says, “All the used fuel we have made during the last 35 years is stored temporary in three small water pools. In Finland we also have the solution for the final depository of used fuel.”

What stopping the countries go fully nuclear?

Even though globally, the acceptance of nuclear energy remains high, in India the nuclear power projects are facing bottlenecks almost in every step. The latest addition is proposed 9,600 MWe power project in Kovvada, Andhra Pradesh. The State government reported to have asked the NPCIL to deposit ` 500 crore towards land acquisition cost and rehabilitation activities.

Commenting on what stopping the country to go fully for nuclear power, Mr Passi said, “I think our politicians are a little scared of public opinion. That can only be fixed with very open, quick and transparent communications. The rule is that the less you know, more scared you are. Truth is also that building a new reactor has become a huge investment.”

He suggests, “We need to get the industry going again with these new and much secure regulations. That would also lower the costs of building a new plant.”

However, Mr Parikh believes, one needs to look at each country in their own perspective. According to Mr Durham, “While several factors influence a nation’s policy toward nuclear energy, the fact is that many nations recognise the need for clean air, base load sources of electricity and want the type of long-term, stable priced electricity that nuclear generates.

Reducing carbon emissions will require a portfolio of technologies and nuclear energy must be part of the mix.”

Conclusion India’s struggle towards the nuclear power generation is slowly proving successful.

If observed, even after facing problems, India is making progress towards being one of the topmost players in the nuclear power generation. R.K. Sinha, Chairman, Atomic Energy Commission once said, “Nuclear energy is the clean and green source of energy and it is a good option for energy if per capita consumption of power in India has to be increased. This way we can leave a clean planet for the generation to come and fight the challenge of global warming.”

Industry Analysis

Smart metering technology evolving in India Smart meters have come a long way establishing their presence in the utility market to developing advanced technology for better utilisation of energy Smart metering has soon become an emerging market in India with utilities focusing on smart metering to improve grid infrastructure. With technology becoming advanced smart meters help utilities to collect information about energy usage transmitting it via fixed communication to utilities. Smart metering today has improved the quality of energy and help in optimum utilisation of electricity.

Are smart meters really smart Smart as a word when used for any device or individual is supported essentially via its way of working. In case of meters whether it is in case of electricity, water or gas, the term ‘smart’ has a lot of significance associated with it. An electronic energy meter logs past 3 to 6 months of consumption (billing data) along with consumption

pattern (load survey). It also has tamper detection intelligence and provides multiple communication ports for retrieving the data. It provides a neat display for consumer’s and meter reader’s convenience.

JK Agarwal, Joint Managing Director, Genus Power Infrastructures Ltd believes, “The features of measurement of electricity in 2-way communication with central server station for real time meter data monitoring and control of load according to electrical parameters/condition, makes the meters really smart.” A smart meter in addition, has features of an alarm notification in case of severe tampering attacks like high ESD (Electro Static Discharge) and EMP (Electromagnetic Impulse). The smart meter not only logs the data but also generates an alarm to preconfigured mobile numbers or email accounts of utility personnel to gain immediate attention.

This feature not only prevents power theft but also provides valuable evidence against notorious consumers.

In some parts of world, the smart meter architecture even enables utilities to plug any communication module on to a smart meter, giving them flexibility to communicate wirelessly (using LPRF radio modules or GSM/GPRS) or through wired medium (PLC or RS-485). “The best part is smart meters are getting

smarter every day. Now a smart meter can communicate over IPV6 networks (every meter having unique IPV6 address worldwide) giving the consumer and utility, absolute information and control respectively,” says Abhed Misra, System Applications Lead - MCU and LPRF, Texas Instruments India.

Relevance of smart meters in India Adoption of smart meter in India is becoming popular and there is a need to adopt the practice of using smart meters. With public and private utilities realising smart meters as vital components for their infrastructure.

Speaking on relevance of smart meters in India Mr Agarwal feels, “Smart meters

There is reduced vendor dependency, interoperable metering system, integrated system for load measurement, controlling and data communication.

Industry Analysis in the Indian context are very much relevant, where demand for electricity is always greater than availability. Smart meters help utilities to manage/control the load/demand in a better manner.”

Smart meters enable time of use based on tariff to encourage consumer to use electricity in off peak time. Smart meters are good in conditions like brown out (reduced load) facility to avoid complete disconnection of electricity.

Smart meters get disconnected during abnormal electrical conditions, avoiding any hazard. With large geographical region it is always a challenging to give best services, IT enabled meters gives real time information to central server station for better services.

Smart meters give all the information through consumer display units and local displays needed for load analysis. This in conjunction with tariff for peak hours can be used to balance the load distribution along with savings on monetary side for consumers. The consumption pattern allows consumers to distribute their load over the day, like using washing machine being used in cheaper tariff hours and using air conditioners on little higher temperatures thereby conserving power and saving money.

This also allows utilities to purchase power if needed from other states or utilities in off peak hours on cheaper rates. Pre-Payment facility discourages defaulters and ensures cash flow for

utilities making them earning profits instead of incurring heavy losses. “It is very important to know that most of the power utilities in India are losing out due to heavy AT&C (Aggregate Technical and Commercial) losses, which generates an absolute need for Smart Meters,” saya Mr Misra.

Advantages of smart meters A smart meter has number of advantages.

For example, smart meters enable consumer with accuracy in their electrical bills. A smart meter sends information to your energy supplier on how much energy you have used on regular intervals. The most important and significant ones are unique in terms of worldwide access, monitoring and control and future ready from a communication perspective.

India has taken the lead in defining standard of smart meters. In a world of multiple technologies for different application needs, the Central Power Research institute of India and Power Ministry could narrow down to 6LowPAN on abstraction layer, IEEE802.15.4/15.4g on MAC and PHY layer and DLMS on application layer for communication. This enables the entire smart meter installation going forward to be uniquely addressable and accessible worldwide through IPV6 address. Each smart meter with inbuilt load control relay provides control to utilities and consumer as well. “With DLMS as a standard application protocol having pluggable communication capability, smart meters will enable any future communication technology module to be plugged and used readily, feels Mr Misra.

Emerging technology in smart metering For any technology to be understood and accepted, the stages of its evolution need to be looked upon. There are several new technologies which are being worked and looked upon to be used in smart meters or smart grids. Some countries are working on Zigbee protocol standard on Sub 1GHz band and are reusing the maturity of that standard for effectively addressing their certain specific needs. Zigbee also uses IEEE802.15.4, appropriately addressing

all the layers of an OSI model of the communication network.

Commenting on the emerging technologies in smart metering Mr Agarwal says, “There is reduced vendor dependency, interoperable metering system, integrated system for load measurement, controlling and data communication.

Improvement in customer response, real time meter data Information.” There are certain installations of smart meters in which the meters offer smart phone connectivity through BLE/Bluetooth as well. “Texas Instruments with its vast portfolio and offerings of LPRF radio’s completely caters to all the technologies and has certified and proven solutions on both, the hardware and software side,” remarks Mr Misra.

Trends in smart metering Smart meters have been usually considered expensive and unaffordable by the Indian consumers. But with the recent demand for smart meters growing companies are coming out with newer technologies which provide optimum utilisation of energy, security from thefts, capacity to handle fluctuating loads etc.

With an Indian standard specification for smart energy meter in place, it is now almost a mandate for all the power utilities to ensure purchase of smart meters only. Mr Misra opines, “It is understood and accepted by all the stake holders in the power sector that with technologies like IP connectivity, load control, theft/tamper alarm and pre-payment, any further delay in using them is only going to cost more and more money.” Leveraging the smartness of smart meters for various benefits is as of late, trending. ”With initial hickups to accept the emerging technology in the last 2 years utilities are accepting the benefits of advance technology for optimum utilisation of available energy resources. The pilots done in initial stages are now started converting into business, inputs from utility and learning from field experience improvising in product features,” says Mr Agarwal. july 2015

Automation to make operation of small hydro plants smoother An in-depth view of how automation plays a huge role in operation of small hydro power plants in India and renewable energy sources, small hydro represents the ‘highest density’ resource and stands in the first place in generation of electricity. Small hydro power is one of the focus areas of power generation since it requires low investment and is one of the most appropriate renewable energy sources to meet increasing energy demands.”

While answering to a query on whether India is in the right direction in operating small hydro power plants, Pankaj Mishra, Industry Business Segment Head - Water and Waste Water, Schneider Electric India said, “Yes, India is on the right track as we have enough of water resources which can be used to generate power. But still lot of emphasis on standardisation is required on improvement, reliable technology, stock production and control for micro and small hydro plants.”

The Indian subcontinent is bestowed with potential to generate hydro power. In India the ministry of new and renewable energy is responsible for developing Small Hydro Power (SHP) projects up to 25 MW station capacities. Most of the potential for hydro power generation lies in the Himalayan states for river based generation and in other states for canal based projects. Currently, India is exploring the limitless opportunities in hydro power generation with setting up of small hydro power plants up to 25-30 MW capacity being the preferred choice as compared to large hydro projects.

India’s focus on small hydro power plants The Ministry of New and Renewable Energy has introduced the Small Hydro Power (SHP) programme to promote power generation from renewable

sources of energy. Small hydro has been identified as a critical source of energy which can help in resolving the crisis of energy which the country currently faces. With small hydro projects being developed by both public and private players the ministry’s aim for SHP’s installed capacity of 7,000 MW by the end of 12th Five-Year Plan doesn’t seem far enough.

Hydro power is the world’s most widely used form of renewable energy. It produces about 20 per cent of the world’s electric power and accounts for almost 90 per cent of electricity generated from renewable sources. It is clean, sustainable and emission-free.

Commenting on potential of hydro power generation in India Ahmad Khan, VP, Power Generation – Automation, ABB says, “Among all the non-conventional

Green Zone Pvt Ltd opines, “In small hydro power plants the automation is only limited to powerhouse. They do not have efficient staff to operate the plants which results in generation loss.”

Experts feel there are many flaws which are hindering growth. According to Nagendra Sharma A, Manager – Proposal Engineering, BFL Hydro, “Still there is huge untapped potential available which is under the licence of influential people who are neither developing nor selling the licence of potential. The power purchase tariff is not changing as per market inflation. The process of approvals and financing is taking long time from concept to completion. All the equipment is designed with higher margins because of old regulations.”

Relevance of automation in small hydro plants With manual systems, the operators need to constantly monitor routine round the clock activities related to plant operation, equipment start-stops, handle disturbances and emergency situations, maintain logs and reports etc. which often lead to fatigue and loss of efficiency resulting in increased human errors. The plant load factor gets affected, leading to poor utilisation of installed capacity.

“To have optimum reliability and availability of the control system we need automation in place so that

man-less operation can be done and increase power generation by efficiently controlling and man monitoring the whole system help us in maintaining the hydropower plant better,” remarks Mr Mishra.

Automation in small hydro plants can drastically enhance operator effectiveness and help take quick actions.

According to Mr Sharma, “Automation can reduce man power and improves accuracy of operation. Preventive and scheduled maintenance will decrease the down time.”

Implementation of an automation system improves the productivity and operational efficiency of a hydro power plant. Automation is the best answer for eliminating the issues encountered in manually controlled units. All relevant information, alarms and events related to the process and control system hardware are made available at one place. Mr Khan says, “Centralised monitoring helps utility owners to effectively monitor the operation of multiple facilities from one place and enables them to take quick, well-informed decisions that have bearing on the overall productivity and profitability.” ABB has delivered the Symphony Plus system at the Ranganadi Hydro Electric plant in Arunachal Pradesh in India, a solution that improves operator efficiency in terms of greater awareness of plant behavior, faster decision and preventive maintenance actions due to the availability of alarm management, trip analysis details, trends etc. on Symphony Plus Operation HMI system.

Difference of automation between large and small hydro power plants There is a lot of difference between the automation used in large hydro plants as compared to small hydro plants. There is a structural difference between small and big hydropower the first is mainly decentralised the later is usually utilised by big structures, which have usually massive environmental impacts.

Speaking on the different ranges of

systems involve in the hydro power plant automation Mr Sharma says, “Large hydro power plants participate the grid regulation and hence governing plays a major role for frequency regulation while, small hydro do not participate in grid regulation only load control and CAM control would be sufficient. Since most of small hydro projects are run off river the turbine required to operate at peak efficiency based on head and flow variation.”

Small hydro plants are mostly located in remote areas with difficult access, in such case the automation system should be easy to operate and maintain by the staff which may not be very skilled. “A simple, rugged and maintenance free Symphony Plus total plant automation system with remote control features will be highly desirable in the case of these small size plants,” assures Mr Khan.

He adds, “In case of large plants, the cost of automation systems could be a small fraction of the total investment, whereas in the case of small hydro plants, this could be significant. Therefore a more economical solution optimally meeting the automation requirement will be necessary. There is also a tendency to club sequencer, governor, and protection and excitation system in a single panel, where as in large hydro plants these are conventionally separate systems.”

The basic difference is when designing small and micro hydropower plant all the production and electrical control are designed within the single UCB and there are not as many panels as compared to larger power plants. “Basically in NCC, in production panels and in panels for auxiliary controls there are metering and other breakup panels for which we have large number of cuticles for that larger power plant but in a micro power plant everything can be controlled within a single panel. In small power plant you may do it with two or three electrical panels,” explains Mr Mishra.

small hydropower plants have seen considerable advancements in the recent years.

for installation of the automation system.

“The control hardware is rugged, reliable and is easy to maintain with online replacement feature. The old hardwired systems have given way to software configurable DCS systems utilising powerful function control blocks and libraries,” says Mr Khan.

Now monitoring of protection relays (IEDs) can be done. The latest numerical protection relays combine multiple functions into a single unit. These relays communicate over IEC 61850 protocols.

The relays support self-calibration and advanced self-diagnostics. Old electromechanical or electronic relays are being now progressively replaced with latest intelligent electrical devices (IED’s) and modular platform hardware which are easily monitored and diagnosed remotely from HMI. When we say Programmable Logic Controller (PLC), we can put the manual control combined into a smart controller so that all the decisions are made by the central CPU and on the backend of it there is a program that can be written and designed as per the required logic so it’s a smart interface that does all the jobs and takes care of all the control points and on front end of the control panel there is SCADA where we can see what is happening on the backend. All operations like turbine and generator control, synchronisation, auxiliary control, gird control, protection and level monitoring all is integrated into single PLC. “We don’t need an additional controller for the individual control which in-turn

helps in reducing the size of UCB and also we can have a multiple user SCADA which can give interface to so many users,” says Mr Mishra. This system is not available in manual system or with PLC in which we can have better control.

Automation products/solutions According to ministry of new and renewable energy there are about 27 equipment manufacturers of small hydro power turbine who fabricate almost the entire range and type of SHP equipment listed in MNRE. Manufacturers’ capacity is estimated at about 400 MW per year.

Schneider Electric produces hydro turbine governors, Programmable Logic Controller (PLC) based automated grid control integrated with level and SCADA based remote monitoring and control for multiple hydro power plants to serve the hydro power sector in India.

While ABB’s product portfolio covers the entire automation needs of a hydro power plant, including control, instrumentation and electrical systems solutions. ABB’s latest and state-of-the art Symphony Plus Control System is a rugged, low maintenance automation system with extensive features specifically for Hydro solutions. Profibus, HART, IEC61850, IEC-60870-5 and Modbus TCP communication protocol.

Case Study

Not just a tool for fabricators and drawing offices Structural engineering has united with the rest of the design industry by taking the leap into 3D Structural Building Information Modelling, a subset of the commonly used concept Building Information Modelling (BIM)

What is BIM? BIM is a collaborative, model-based way of working and is one of the key elements in the building process where the majority of structural information is created. Open BIM interfaces make it possible for all design information to be produced and managed within a single 3D product model. Such open interfaces are crucial in order to tie different design applications and disciplines together.

Tekla Structures is the first BIM software solution to fully integrate the entire structural design process from conceptual design to detailing, fabrication and erection. The comprehensive 3D model keeps all components current providing a faster, higher quality and richer design process. Tekla Structures can be used to collaborate with other existing applications, or solely as a platform to develop a customisable internal solution.

About Canham Consulting Ltd. Canham Consulting Limited is an independent company, based in Norwich and highly regarded for its expertise, approachability and practical solutions to engineering problems in the residential, commercial, industrial and retail sectors. The company recently moved into new offices and has taken the opportunity to become fully networked with an ADSL connected server, subsequently allowing Canham to upgrade its software systems as well.

Chris Dewick joined the company just over 4 years ago and his primary roles are those of drawing office manager and senior draughtsman. “We were sort of coerced into phasing out our 2D draughting technology. A client’s request for a 3D detailed model was the basis to seek out a new solution. Tekla Structures allowed us to produce a realistic view of proposals, giving our client the facility to see the project via a virtual reality walkthrough model.�

Electrical & Power Review

Chris goes on to say, “Canham have used Tekla Structures for over a year. We expect our annual turnover to increase now that we have the means to take on more challenging projects. We have just finished modelling a new Construction College (120 tonnes main steelwork only). Tekla Structures minimised overlapping work phases and errors, which translated into shorter project lead times and significant cost savings. Tekla Structures collaboration capabilities allowed us to issue files directly to the steelwork contractor, putting us a good 2-3 months ahead of schedule. We were also able to clash check against other disciplines. In addition, our website was constantly updated to reflect the changes made to the model. Anyone can access and view the model with Tekla’s free web viewer.”

About Arup Arup was founded in 1946 as part of an international firm of engineers and consultants providing design, project management and consultancy services to a wide crosssection of public and private sector clients. The company works primarily in the built environment providing services for every stage of a project lifecycle.

Ray Young is CAD Leader in the London office and has worked with Tekla Structures for the past 7 years. “The decision to move forward with CAD was reasonably straightforward. We needed to work in a 3D objectmodelling environment. Tekla Xsteel was already proven to be the best steelwork package on the market.”

Ray continues, “With the introduction of Tekla Structures we can now model in both steel, concrete or any other material. The fact that Tekla Structures is a multi-material modelling system helps the structural geometry stay consistent. The exceptionally smooth collaboration and information management application make the overall process controllable. The same model can be utilised for producing analysis & design results and reports. Our general arrangement drawings and documentation are 100 per cent accurate and always reflect the current status of the project. We get more from the 3D model in the way of views and details. The Tekla Structures visualisation capacity provides us with superior image quality.”

Conclusion Canham Consulting is currently using Tekla Structures mainly for their steelwork requirements. However, the company has plans to fully utilise the multimaterial modelling and collaboration functions that Tekla Structures has to offer. It looks forward to getting the added benefits that Arup already sees with steel, concrete and structural design professionals working with the same shared, always up-to-date model throughout every stage of a building project.

Sharplex auto backwash filter Operation The water to be filtered enters into the filter and flows through the slotted tube elements from inside to outside. Impurities or sediments particles are retained on the smooth inner side of the filter elements. The particular design and shape of filter element guarantee an even flow resulting in a low pressure drop and equal loading of the filter area. As the loading of the filter area increases steadily during the filtration process,

the differential pressure between the contaminated and the clean sides of the filter element also increases.

When the differential pressure reaches its pre-set values, the back-flushing process starts automatically. During back-flushing a geared motor rotates the flushing arm under each filter element in succession and the backflushing valve opens briefly. Due to a pressure differential between the filtrate side (clean water) and to open back-flushing line, a small volume of the filtrate is flushed back through the filter elements. The impurities or sediments which may collected on side of the filter elements is loosened and flushed out of the filter via the flushing arm. When all elements in the filter have been cleaned, the backflushing cycle is complete. When one filter element is under back-flushing other elements continue the filtration and therefore filtration process do not stop and it is continuous.

Megger introduces unique cable testing and diagnosis system information about the quality and the condition of their cables. This is made possible thanks to the brand-new 50 Hz Slope Technology. For the first time, it has become possible to immediately locate faults in underground cables during the actual PD measurement.

Megger’s revolutionary new TDS NT is a unique, all-in-one cable testing and diagnosis system. It offers two well-proven wave forms – Very Low Frequency Cosine Rectangular (VLF CR) for withstand testing and Damped AC voltage (DAC) for nondestructive Partial Discharge diagnosis.

These can be used to test cables to international standards such as the IEEE 400.3 and IEC 60502-2. The TDS can also be used for DC tests and sheath tests to the IEC 60229 standard. When paired with a step voltage sensor, it can even be used for precise pinpointing of sheath faults.

Network operators can now get faster and significantly more reliable Electrical & Power Review

With the 50 Hz Slope Technology for the first time worldwide a withstand test with VLF cosine-rectangular voltage (VLF CR) and PD diagnosis with damped alternating voltage (DAC) is combined in one unit.

This allows an efficient and integrated solution for precise inventory of the network infrastructure. The important fact here is that the PD measurement data, gained with the VLF CR or with the DAC test voltage, can be compared directly with the 50 / 60 Hz network voltage.

TDS NT consists of a multifunctional, compact voltage source and a PD detector. It can be used to test cables

according to the international standards (e.g. IEC 60502-2 and IEEE 400.2) with VLF-CR. In addition, a PD diagnosis using the new 50 Hz Slope Technology can be performed simultaneously with the help of the PD detector.

Alternatively, the TDS NT can also be used for PD diagnosis with the proven damped AC voltage (DAC). In practice, the PD diagnosis has been established nationally and internationally as an effective method of measurement. It is especially useful for commissioning testing, as it is the only way to check to reliably check the quality of workmanship of the accessories.
