India is facing possible energy supply problems in the coming months due to coal shortages and a post-pandemic surge in demand, the power minister. China and European countries face energy crises that are disrupting global supply chains and sending prices soaring. "Demand is not going to go away; it's going to increase... added 28.2 million consumers. Most of them are lower-middle class and poor, so they are buying fans, lights, televisions sets," he said. India's coal-fired power stations had on average four days' stock at the end of September, the lowest in years. More than half the plants are on alert for outages and the government is mulling bringing idled power stations back into operation. Coal accounts for nearly 70 percent of India's electricity generation and around three-quarters of the fossil fuel is mined domestically. This pushed up prices sharply for coal buyers, including power stations. Buying coal abroad is expensive because international prices have also soared. Until supplies stabilise completely, we are likely to see power outages in some pockets, while customers elsewhere may be asked to pay more for power.

Human activities emit 51 billion tons of greenhouse gases each year. At this pace, by 2050, the global temperature will rise by more than 2 degrees, consequences of which are going to be catastrophic. Rapid rise in global temperature due to greenhouse effect has caused natural calamities like forest fires in Australia, melting of glaciers in Antarctica, cyclones in coastal areas, frequent & violent weather events, droughts in Maharashtra etc. It is of utmost importance to take action now, to aim for Net-Zero Emissions. Reducing emissions and sucking carbon from the atmosphere are the two major approaches to ensure Net-Zero by 2050, the human race must achieve net-zero emissions to avoid disastrous climatic catastrophes. Recently, Lowsoot (www.lowsoot.com), India’s leading environmental startup company has teamed with eBikeGo, India's leading electric two-wheeler mobility platform to address this gap and find solutions to reduce carbon emissions in the country. Lowsoot was selected by eBikeGo to set up a climate fund and an environment challenge organized as part of this endeavour. All startups focusing on environmental issues and electric mobility were invited to participate in this competition. Lowsoot got selected and considered for the incubation out of a total of 1540 applications received by eBikeGo. Lowsoot helps individuals track and erase their daily carbon footprint. In its endeavour to accelerate the world towards net-zero eBikeGo is supporting Lowsoot.

Power generation industry has travelled a long way from its first articulate level Even as the power ministry looks to focus on providing power supply to all, besides ensuring generation of surplus power, the number of diesel power generator sets in the country may be on a rise. None of the government agencies publicly share any data related to the number of operating diesel generator sets (gensets) in India. However, data sourced through industry sources shows that diesel power generator sets capacities have risen at a rate of around 5,000 megawatts (MW) per annum in the last two years in the country. According to data sourced through its internal research, private power producer Tata Power said capacity of diesel gensets is estimated to stand at 90,000 MW as on 2016-end, from 80,000 MW in 2014. Increase in capacity is rather surprising as the past three years have seen the government focusing on increasing power supply in the country, besides witnessing a surplus condition in some scenarios.

On Friday, Power Minister Piyush Goyal took to social media platform Twitter and said that around 4,396 megawatts of power was available at rate of Rs. 2.59 per unit for states. Industry experts attribute the rise in diesel gensets to the largely erratic and uneven power supply in the country, besides issues faced at the transmission and distribution level. "Diesel generator sets are operated only for a short period of time during the day and are used as a back-up power supply," said Ashok Sethi, chief operating officer and executive director for Tata Power. "The rise is not surprising as generator sets are a solution for erratic power. Unless, the country moves towards reliable power supply and solves the transmission and distribution related issues, this trend will continue," said an industry official who did not wish to be identified. Power demand deficit peaked at 0.8% or 1,197 MW in April due to erratic power supply in the country. Another industry consultant added that

shaving purpose. Geographical Outlook The high-volume adoption of 5 kVA–75 kVA gensets in commercial applications, including telecom towers, retail outlets, offices, malls, and hotels, is projected to drive their usage. Domestic and cross-border investments, along with the digitization projects undertaken by the government and revival in the commercial real estate sector, are expected to result in the establishment of single- and multi-tenant data centers, thereby propelling the installation of 5 kVA–75 kVA diesel generator (DG) sets. The market in the country is projected to witness a negative impact of the COVID-19 pandemic, on account of the shutting down of commercial and industrial establishments, in order to curtail the spread of the disease. Furthermore, this has temporarily put the production of diesel gensets on hold. There has been a slump in the demand for diesel gensets from the first quarter of 2020, due to the locking down of various commercial establishments, including retail stores, offices, telecom towers, hotels, and airports, which account for a major share in the India diesel genset market. However, with the lifting of the government-imposed lockdown and allowance of air and rail travel, the industry is likely to witness slow recovery in the near future. In 2019, Tamil Nadu, Andhra Pradesh, Karnataka,

in India diesel gensets market. Power generation industry in India is largely split into conventional & non-conventional ways of generating electrical power. Historically, in India, prominent sources of generating electrical power are, hydel (water based), thermal (coal based), nuclear (atomic based) along with these sources diesel engine based electrical power generation has been popular. Indian diesel generator set market (only based on high speed diesel) has been witnessing growth owing to infrastructure expansion, establishment of new industries & changing business environment in the country. Strong economic growth coupled with power deficits in many parts of the country would foster the demand for diesel generator sets. Also, growing number of telecom towers in the country are expected to boost the diesel generator set market. Diesel engine-based power generation has been growing during this decade, in applications such as prime power or continuous duty as well as in backup or standby. It is worthwhile to understand the significance of start-ups in this industry in the context of challenges & opportunities. ‘Power generation’ is a casually used term but when it comes to receiving end of usage, power generated gets transmitted through transmission network which is then followed by local distribution using distribution network.

day or night, any human being needs electrical energy. Presently, in India, the electrical power need is fulfilled using conventional & non-conventional sources of energy. Basic electrical need across the nation gets catered using boiler (coal fired) or turbine (steam or nuclear or hydel operated) & diesel generator set. Day-by-day, with the influence of ‘Make in India’ initiative, infrastructure segment in India & other industries across India have started peaking up the electrical power demand. In the year 2015, IBEF has done extensive survey on ‘Electrical Machinery’ potential mapping in the Indian market, till year 2022. They have covered power generation machinery, distribution machinery & transmission machinery under ‘Electrical Machinery. Study indicates that electrical power generation machinery installed capacity is expected to grow from 267 GW to 350 GW from year 2015 to year 2022 which is CAGR of 3.9% whereas power demand is expected to have growth at CAGR of 17%. This clearly indicates that there is high probability of having peak demand for electrical power across country. During the same research, IBEF, in reference with a report published by Ministry of Heavy Industries, GoI, indicated to have CAGR of 27.2% for backup power generation units. Generators are expected to have 5-fold growth till 2022. Boilers are contributing to 63% of total generator industry followed by turbines with 27% & remaining approximate 10% is catered by Diesel engine driven power generator. High Speed Diesel is the one which is famous ‘Diesel’

||www.electricalmirror.net||

utilized to power automobiles or generator sets. Presently, in the Indian market, High Speed Diesel engine-based power generation is enjoying 72% of market share against other sources. IBEF report indicates that the electrical machinery market has been opened for 100% FDI starting 2013 end, which is in line with the Central Pollution Control norms implementation strategy by the GoI. Even though there are government efforts to make India free from power-cuts & generate surplus power with continuity in supply & better quality of power, still there are gaps in present establishments & hence the option like UPS or Diesel engine-based power generation is becoming a popular source of back-up electrical supply. With this change in pollution level norms on diesel enginebased power generation, various multinational generator set manufacturers have invested in India & have started challenging the established domestic giants. In the recent past, government has assigned various regional SEZ’s which are attracting these multinational giants to set up plants or factories & become competitive in global market as well. Some of them are directly investing or some of them are coming in via joint venture route. One of the well-known research organizations in this field, RNCOS, have indicated in their report ‘India Diesel Market Outlook-2018’ that generator set market in India is on a growth path primarily due to peak demand in electrical power & also due to lack of continuous availability of power with better quality. Also,

||www.electricalmirror.net||

the ‘back-up’ power availability has started playing a crucial role in Indian industries such as engineering, infrastructure, realty, hospitality & many more. This report indicates that the generator market has seen a growth of 9.5% in the year 2013 over its previous calendar year. It further indicated that it would have similar growth in next 5 years to come. The Indian diesel generator market is expected to grow at 11% CAGR in the product range of below 100 KVA & higher rating product ranges are expected to grow at CAGR of 7.8% till the year 2018.Power generation industry has been through various phases of evolution. Generator manufacturers have started understanding the need of market or customers from their product than merely selling the generator sets. One of the critical evolution phases was sustaining in the change of pollution norms laid down by the GoI. First norms were laid down 10 years ago (CPCB-1) & the second were laid down in the year 2014 (known as CPCB-2). These have compelled the industry players to work on the structured or well organised sales process. The reason to change norms was purely based on environment protection & bringing in technical advancement in product, buying options for the buyers including the imported & domestic products. This has resulted in introduction of full-time availability of imported generator sets in India. Imported generator-set manufacturers have increased their capacities in India helping in boosting the Indian economy. To start with, the boost in economy looks

to be negligible but the plans for next five years would attract investment of approximately USD 10 Bn. In the era of CPCB-1, India power generation segment has seen most dominating domestic players like Cummins India Ltd., Kirloskar Oil Engine, Greaves, Ashok Leyland & to some extent Mahindra & Mahindra. As compared to presence of only 4 major domestic players in the past, there are 8 major players now, essentially adding 4 giants from global market (Caterpillar, Perkins, MTU & Mitsubishi). Over the years, since 2013, market potential for diesel generator sets has gone up from 75,000 units per year to 100,000 units per year, making it to approximate increase of turnover in value terms as INR 3000 crore annually. This estimates out to 25% growth in potential & doubling the number of players. Power generation industry evolution Power generation industry has travelled a long way from its first articulate level of ‘chaotic or chaos’ to present days ‘reportable’ stage. In one of the recent articles by ‘Markets & Markets, on generator set industry growth prospects worldwide (till year 2020), growth indicated to be around US $ 20 Bn USD from present level of US $13 Bn (2015) which means at CGAR of 5.4%. Primary reasons for this growth are indicated to be growing need of continuous power supply & increasing power outages. The report also segments the diesel generator market on the basis of end-user, which includes industrial (power generation/ utilities, oil, gas & others), commercial (IT & telecom, healthcare, & others) and residential. The industrial segment is one of largest users of diesel generators and occupies more than 50% of the total market share in the end-user segment of the diesel generators market. This market is expected to grow at the highest CAGR during the forecast period, owing to chronic power outages & rapid growth of industries, infrastructure, IT & tele-communication industry across the world. Growing industrialization & frequent power outages are driving the demand for diesel generators in this region. The diesel generator market in India is expected to grow at the highest CAGR, owing to growing IT, data centre, telecom, & ongoing infrastructure development programmes in the country. Start-ups are essentially of two kinds. The first one starts ground up or the one which no one has thought about. In last two to three years, many such start-ups came in & vanished on their own. This type of start-up is difficult to create but once created often sees unprecedented growth. The second type is primarily the ones that do not want to

reinvent the wheel. They are interested to adding old sauce in a new dish with little value addition, either superficial, or in actual, to create something new &innovative. Both these major types of start-ups are seen in all industries. Whatever may be the kind of start-up, Indian start-ups face their own set of challenges & some stellar opportunities. With India power-starved, the millions of diesel generator (DG) sets working to meet the shortage in industrial and commercial units now add up to a cumulative capacity of 90,000 MW. That figure is nearly equal to what was India’s total installed power generation capacity just over a decade ago (March 2002) and about 36 per cent of the current installed generation capacity. As per more figures compiled by the country’s power regulator, the DG capacity is growing at a rate of 5,000 MW to 8,000 MW every year. That is higher than the cumulative nuclear and solar capacities being added year-on-year in the country. Besides, the estimate, presented by the Central Electricity Regulatory Commission (CERC) at a recent meeting of its Central Advisory Commission here, is largely restricted to just the big DG sets of over 100 kvA (kilo volt ampere) used by industrial and commercial units as a back-up to the unreliable and insufficient power supply to non-domestic consumers across nearly all states. Taking into account domestic loadrunning on gensets would take this figure to beyond 90,000 MW. Apart from the fact that they spew tonnes of carbon-dioxide, the gensets run on subsidised diesel. The cost of generation from a mid-sized DG set is over Rs 14-15 per unit. Currently, thermal generation capacity of over 48,000 MW

||www.electricalmirror.net||

is stranded in the country in the absence of coal linkages and non-closure of power purchase agreements (pacts with buyers of electricity), or due to the lack of flexibility in diversion of coal. Aggravating matters is the fact that despite a cumulative installed generation capacity (as on August 31, 2014) of 2,50,257 MW, demand up to only 1,40,000 MW is met, primarily due to transmission infrastructure failing to keep pace with generation capacity. Interestingly, as per the Central Electricity Authority’s latest estimate, the country’s diesel-fuelled power capacity is just 1,199 MW. This means that the massive capacity of 90,000 MW from DG sets is completely outside the realm of policymaking and official statistics. While the break-up of this DG capacity was not available, officials involved in the exercise said the data was largely collated from manufacturers of DG sets. At the consumer level, the spread of DG sets is increasing with every passing year, considering that practically all commercial establishments, mid-to-large sized factories and apartment complexes are equipped with back-up power that runs on diesel. The specific suggestion put up before the CERC at the May 16 advisory commission meeting was that state electricity regulators (SERCs, which are the equivalent of CERC) be asked to impose “restrictions” on use of diesel gensets in order to mitigate the risk of energy security and for the protection of environment. A CII representative countered this saying that industry, by and large, does not run DG sets out of choice, but as a matter of compulsion. In the absence of reliable and quality power supply from distribution utilities, most of which are

||www.electricalmirror.net||

state-owned electricity boards, industry is forced to rely on back supply, despite the prohibitive costs. This also involves bribing fuel pump owners to ensure a regular supply of diesel, the representative said. A July 2014 report prepared by research and consulting firm GlobalData, focusing on energy and healthcare industries, also notes that while the US, China and India are currently the top markets for diesel gensets, their market share will improve only in China and India by the end of the forecast period of 2020. According to Siddhartha Raina, Senior Analyst for GlobalData: “China and India each face a considerable gap between their power supply and demand, creating attractive markets for diesel genset manufacturers. High power deficits, coupled with significant economic growth potential, are expected to be the strongest drivers behind these markets’ expansion.” Conclusion Expanding activity across all segments in the manufacturing sector, construction and infra sectors, and standby power from the residential segment, all add up to generating a robust demand for gensets in India, across all types and capacities. A trend boosting market growth for gensets is technological advances. Improved fuel economy continues to be the most significant advancement in diesel engine technology. Though many end-users prefer gasoline-powered equipment, the diesel engine segment has a solid end-user base in data centers as it is an economical option - an important parameter considered for owning power backup equipment. Over the years, several initiatives and changes have been implemented to improve the overall efficiency of engines in a diesel genset. Most of the modifications involve igniting of power within the engine itself, derived from a combination of oxygen and fuel. According to the report, a key growth driver is frequent power outages. Power outages form one of the common problems faced by developing countries such as India. India, being one of the fastest developing nations in the world, depends largely on electricity for its industrial, commercial, infrastructure, transport, and other sectors. India is the third largest electricity producer and consumer in the world after the US and China. However, an estimated 27% of the energy generated in India gets lost during transmission or is stolen. Peak supply falls short of 9%, and frequent power outages last for an average of 10 hours in many regions of the country. EM || October 2021 ||

Thermal imaging camera systems play a pivotal role To limit the spread of the highly contagious COVID-19 virus, many businesses across the globe have deployed social distancing requirements, stringent cleaning protocols and capacity limitations as part of their plan to safely reopen. Even with these measures in place, retailers, office complexes and educational facilities are recognizing that technology will also play a critical role to help identify individuals who may have the virus even before that person enters the premises. This is where thermal imaging camera systems play a pivotal role, with casinos, retailers and manufacturing facilities among the first to invest in and deploy this solution to help them to proactively detect an elevated temperature in visitors or employees prior to entry. Many more businesses are expected to follow suit in the coming weeks and months, as they look for additional measures to reduce the spread of the virus and to safely reopen in a COVID-19 world. Thermal surveillance has been part of the traditional physical security and outdoor perimeter detection portfolio for years. This surveillance systems work by picking up heat emitted by an object or a person and can detect vehicles or individuals in a predetermined area. It is especially useful in the dark, when a traditional surveillance system might be limited in its detection capabilities due to limited light sources. With the spread of COVID-19, the security industry quickly began to look at how security solutions, and specifically thermal imaging cameras systems, could be leveraged as part

||www.electricalmirror.net||

of the reopening plan for businesses and schools. Thermal imaging camera systems with a blackbody temperature calibration device offer a more accurate solution that also provides a higher throughput of people for scanning, as well as the ability to locally and remotely monitor and manage alerts. They also integrate with other technologies, such as a turnstiles, physical access control systems and intrusion devices. The combination makes this type of solution ideal for facilities that require a first line of defense in high traffic areas or when rapid people flow is essential - commercial office buildings during morning rush hour, transit stations or manufacturing plants during shift changes. Systems that incorporate a blackbody device typically employ a dual sensor camera, which has a visual sensor and a thermal sensor built into the camera, along with a separate blackbody device. The blackbody device is an integral part of thermal imaging as it relates to detecting elevated skin temperature scanning as it provides the ongoing calibration of the infrared temperature sensor for a higher degree of accuracy. It also helps maintain thermal equilibrium through its management of radiation while providing a near-perfect temperature source, preventing the temperature readings from being influenced by a common issue of thermal sensors called drift. Throughput is also an important consideration for businesses to take into account. Achieving effective throughput, through a turnstile or

a busy main entry door with card reader, requires a single person at a time to be able to walk through without stopping. To ensure a high level of accuracy and to maintain proper resolutions with a thermal imaging camera system, an interval of two to four seconds between each person is required. Depending on how many people need to be processed, elevated skin detection cameras can be deployed at multiple lanes to accommodate anticipated traffic – between 15 and a maximum of 30 individuals per minute can be processed by a camera-black body pair while achieving medical grade accuracy in line with IEC 80601-2-59:2017 standards when using compliant devices and proper installation. Systems that provide a variety of alerting capabilities can provide a high level of flexibility for organizations incorporating elevated skin temperature into their new health and safety operations. While a vast majority of users will deploy a thermal solution with local monitoring, alerting and response, some systems also feature integrations with video management systems for remote monitoring and management. VMS integration can also prove a valuable tool for automated contagion reporting for contact tracing, controlling access through the VMS and PACS integration and activating an organization’s event response protocols. For local monitoring and response, some thermal imaging cameras may include a built-in speaker for configurable audible alerts. These alerts can be customized in response to detecting a temperature variation beyond the norm. The audible alert can announce or alert that a temperature alert has been detected and instruct an individual to proceed to a second scanning area or to stay in place while the appropriate person responds. Installing thermal imaging cameras for scanning elevated skin temperatures will soon become the new normal as more and more companies migrate back to the workplace. Businesses should follow best practices with the installation, deployment and usage following standards of these devices, to achieve the optimal success and the best possible accuracy in elevated skin temperature scanning. Thermal imaging cameras are devices that translate thermal energy (heat) into visible light in order to analyze a particular object or scene. The image produced is known as a thermogram and is analyzed through a process called thermography. Thermal imaging cameras are sophisticated devices that process the captured image and display it on a screen. These images can be used for immediate diagnosis or processed through specialized software for further evaluation, accuracy and report output. Thermal imaging cameras take measuring temperature to the next level; instead of getting a number for the temperature you get a picture showing the temperature differences of a surface. What Do Thermal Imaging Cameras See? Visible light is what we see around us every day. It is the only part of the electromagnetic spectrum that we can see. Visible light only takes up a small area in the electromagnetic spectrum and infrared radiation (IR) represents a larger percentage. If we want to see what’s going on in other parts of the spectrum we need specialized equipment. All objects absorb, reflect and sometimes transmit energy at different

levels. Different materials will give off heat or cold energy at different rates. It’s this energy that can be detected by infrared equipment and displayed as images. Thermal Imaging Camera Applications and Uses Originally developed for military use during the Korean War, thermal imaging cameras have migrated into other fields and have found many uses. Firefighters use them to see through smoke, find people and localize hotspots of fires. Law enforcement uses the technology to manage surveillance activities, locate and apprehend suspects, investigate crime scenes and conduct search and rescue operations. Power line maintenance technicians locate overheating joints and parts to eliminate potential failures. Where thermal insulation becomes faulty, building construction technicians can see heat leaks to improve the efficiencies of cooling or heating. Physiological activities, such as fever, in human beings and other warm-blooded animals can also be monitored with thermo graphic imaging. They are also common tools used by home inspectors. Thermal Imaging Camera Features Thermal imaging cameras can be purchased with the bare minimum of features that only read the temperature of the fixed center crosshairs on the display or with multiple features that allow the user to select multiple moveable crosshairs and draw comparisons between them to show the high, low and average temperatures on the display. Thermal imaging cameras have user-selectable multiple color palettes, such as black/white, iron or rainbow. The iron palette is most commonly used by home inspectors. The black/white palette helps identify details on an image, and the rainbow palette has the best thermal sensitivity for displaying the differences in temperature. See sample images below of some color palettes. What to Look for in a Thermal Imaging Camera? There are a number of components that contribute to both the quality and the cost of a thermal imaging camera. The two most important factors are the detector resolution and the thermal sensitivity. The detector resolution describes the number of pixels. The most common resolutions are 160 x 120, 320 x 240 and 640 x 480 pixels. A 320 x 240 detector produces an image composed of 76,800 pixels. Since each pixel has a temperature associated with it that is 76,800 temperature data points. Higher resolutions also produce visibly clearer images. Thermal sensitivity is the smallest temperature difference the camera can detect. A sensitivity of 0.05° means the camera can distinguish between two surfaces with only a five-hundredths of a degree temperature difference. Another important factor to consider is the thermal imaging camera’s temperature range. The range tells what the minimum and maximum temperatures are that the camera can measure (-4°F to 2200°F is typical). To obtain the best thermal image to analyze, there are four adjustments that can be made to most cameras: focus, emissivity setting changes, reflective temperature setting changes and thermal tuning. Each of these adjustments must be considered when selecting a thermal imaging camera.

Just like a standard camera, the lens of the thermal imaging camera needs to be focused to enhance the clarity of the image. Most cameras can be focused by twisting the lens. More sophisticated cameras have a push-button focus. Emissivity is the amount of radiation emitted from an object compared to that of a perfect emitter of radiation when both are at the same temperature. Adjusting the emissivity is important when taking temperature measurements or when comparing the temperatures of two different objects. Not all cameras allow the user to input reflective temperature. The reflective temperature setting allows the user to compensate for surrounding objects’ temperature reflecting on an object. Just like emissivity, reflective temperature is important when taking temperature measurements or comparing two objects’ temperatures. Not all cameras allow the user to input reflective temperature. Thermal tuning the camera involves adjusting the span or temperature range that the camera sees while in manual viewing mode. Manual mode allows the user to adjust the span to a desired range, and the camera will always display this temperature range. Using the manual mode is best when used to bring out temperature differences of the object being viewed. Thermal Imaging Camera Limitations Because thermal energy can be reflected off shiny surfaces, thermal imaging cameras cannot see through glass. Thermal imaging cameras can be used to gather information about the inside of a wall, but they cannot see through walls. It is also important to know that thermal imaging cameras should not be used as the only deciding factor that a problem exists. Using other instruments should always be used to confirm the problem. The History of Thermal Imaging Cameras Thermal imaging goes all the manner back to 1800 once infrared was discovered as a type of radiation on the far side red lightweight. Whereas infrared technology has several uses its most notable for thermal imaging cameras. A typical camera captures the sunshine we will see with our eyes, however a thermal camera captures “invisible” infrared emission, creating technology like vision spectacles attainable. The first thermal camera is nearly a hundred years previous, and it spent a lot of its youth utilized in the wars of the 20th century. But today, they’re home items. Anyone can purchase a camera with a thermal imaging sensing element for simply some hundred greenbacks and use it as a hobby or recreation. Thermal Cameras Thermal imaging may be a methodology of raising the visibility of objects during a dark atmosphere by detection the objects' infrared and making a picture supported that data. Thermal imaging, near-infrared illumination, low-light imaging and are the 3 most ordinarily used visual sense technologies. In contrast to the opposite 2 strategies, thermal imaging works in environments with none close light-weight. Like near-infrared illumination, thermal imaging will penetrate obscurants like smoke, fog and haze. Here's a quick rationalization of however thermal imaging works: All objects emit infrared energy (heat) as an operator of their

temperature. The infrared energy emitted by Associate in nursing object is understood as its heat signature. In general, the warmer Associate the nursing object is the additional radiation it emits. A thermal imager (also referred to as a thermal camera) is actually a heat sensing element that's capable of detection little variations in temperature. The device collects the infrared from objects within the scene Associate in Nursing creates a picture supported data regarding the temperature variations. As a result of objects are seldom exactly constant temperature as alternative objects around them, a thermal camera will notice them and that they can seem as distinct during a thermal image. 11 options to seem for in thermal imaging software package Robust desktop and itinerant software package is a vital side of infrared scrutiny workflows. The software package will facilitate enhance and clarify pictures, add analysis and share professional-looking reports in applications spanning mechanical, electrical, equipment and building medicine and additional. It’s necessary to notice that analyzing thermo graphic mental imagery accurately needs special coaching to require under consideration emissivity of objects and alternative factors which will influence temperature measurements by infrared cameras. Just as skilled photographers use a software package to show pictures into beautiful works appropriate for a business enterprise or widespread sharing, thermographers use software package as a tool to investigate so enhance and fine-tune thermal pictures that the data will be shared with manager’s and others.

ADVANTAGES Thermal cameras let individuals see what their eyes can’t: invisible heat radiation emitted or mirrored by all objects, no matter lighting conditions. A number of the best advantages of thermal imaging are available in the domain of security. Security cameras became a staple of protection for several (if not all) major businesses across the country, and in such a landscape, the necessity to supply quality pictures is vital to supply constant protection against potential intruders. Thermal cameras provide superior protection in difficult conditions. 1. Low-Light Situations 2. resistant to Visual Limitations 3. Camouflaging Foliage 4.

Railways scraps thermal cameras tender after firms allege advantage China The railways has scrapped a tender for thermal cameras meant for ‘Covid surveillance’ after Indian firms alleged that the tender specifications favoured a Chinese company. In June, Railtel, the railways’ telecom arm, had issued a tender for thermal temperature screening AI-based surveillance cameras for assistance in Covid-19 surveillance. The government company has decided to issue a fresh tender after the controversy. “EOI for selection of partner for thermal temperature screening solution to RCIL’s customers’ stands cancelled with immediate effect. Fresh EOI will be published soon,” a notice by the PSU said. This comes at a time when the Indian government has banned 59 apps, mostly having Chinese links, saying they were “engaged in activities prejudicial to sovereignty and integrity of India”. India and China are involved in a tense border stand-off along the Line of Actual Control in Ladakh. A brutal brawl in Galwan Valley on June 15 led to 20 Indian and an unspecified number of Chinese soldiers dead. In a letter written to Railtel, one of the vendors said the pre-qualification criteria laid down for the OEM & bidder has some anomalies and ambiguities. Hindustan Times has seen a copy. “Even after the release of the latest corrigendum (on June 23) the

ELECTRICAL MIR ROR

department has some ambiguities too in technical specifications. Specifications issued are biased to Chinese OEM i.e. Hikvision, Specs clearly mentioned DeepinMind technology which is a proprietary feature of Hikvision NVRs,” the letter said. Indian firms have alleged that artificial intelligence technology DeepInMind - which is specified in the tender is a proprietary feature of Chinese firm Hikvision, a company partly owned by the Chinese government. According to Hikvision’s technology, Network Video Recorder (NVR) has a “mind” of its own and can analyse and classify human and vehicle targets from video streams. Under the specifications mentioned in the tender for temperature screening with facial recognition and mask detection, Railtel mentioned “Special interface in DeepinMind NVR.” The specifications for the cameras include temperature screening with facial recognition and mask detection, simultaneous temperature screening for multiple persons, detecting whether people wear masks and giving timely alarms on people without masks. While the initial tender for these cameras issued on June 9 excluded a crucial specification called “black body” temperature - the ability of the cameras to accurately measure temperatures emitted by a person to say whether a person has fever or not - and the DeepinMind technology specification, they were included in the revised tender issued on June 23. Railtel had floated the tender to purchase around 800 such camera systems. Hindustan Times had on November 10 last year reported the national carrier is planning a complete overhaul of security at railway stations through the use of facial recognition technology backed by artificial intelligence. It also planned to link the facial recognition system (FRS) with existing databases such as the Crime and Criminal Tracking Network & Systems (CCTNS) to identify criminals prowling railway stations. Thermal Imaging Systems and COVID-19 • When used correctly, thermal imaging systems generally have been shown to accurately measure someone’s surface skin

||www.electricalmirror.net||

temperature without being physically close to the person being evaluated. Thermal imaging systems offer certain benefits in that other methods need a closer proximity or contact to measure temperature (for example, non-contact infrared thermometers or oral thermometers). • Temperature-based screening, such as thermal imaging, is not effective at determining if someone definitively has COVID-19 because, among other things, a person with COVID-19 may not have a fever. A diagnostic test must be performed to determine if someone has COVID-19. • Thermal imaging systems have not been shown to be accurate when used to take the temperature of multiple people at the same time. The accuracy of these systems depends on careful set-up and operation, as well as proper preparation of the person being evaluated. • Thermal imaging systems have been used by several countries during epidemics, although information about their effectiveness as part of efforts to reduce the spread of disease has been mixed. • The FDA issued the Enforcement Policy for Telethermographic Systems During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency guidance to help expand the availability of thermal imaging systems and mitigate thermometer shortages during the public health emergency. The guidance sets forth an enforcement policy that is intended to apply to all thermal imaging systems that are intended for medical purposes for the duration of the public health emergency related to COVID-19, and provides recommendations regarding performance and labeling of such systems. Benefits of Thermal Imaging Systems • The person who handles the thermal imaging system is not required to be physically close to the person being evaluated. In fact, the person who handles the thermal imaging system could be in a different area or room. • The thermal imaging system may measure surface skin temperature faster than the typical forehead or oral (mouth) thermometer that requires a close distance or physical contact with the person being evaluated. • Scientific studies show that, when used correctly, thermal imaging systems generally measure surface skin temperature accurately. Limitations of Thermal Imaging Systems • Although these systems may be in use for initial temperature assessment to triage individuals in high throughput areas (for example, airports, businesses and sporting events), the systems have not been shown to be effective when used to take the temperature of multiple people at the same time. They should not be used for "mass fever screening." • These systems measure surface skin temperature, which is usually lower than a temperature measured orally. Thermal imaging systems must be adjusted properly to correct for this difference in measurements. ||www.electricalmirror.net||

These systems work effectively only when all the following are true: 1. The systems are used in the right environment or location. 2. The systems are set up and operated correctly. 3. The person being assessed is prepared according to instructions. 4. The person handling the thermal imaging system is properly trained. Proper Use of Thermal Imaging Systems The person who handles the system should follow all manufacturer instructions to make sure the system is set up properly and located where it can measure surface skin temperature accurately. The person who handles the system should be trained to properly prepare both the location where the system will be used, and the person being evaluated, to increase accuracy. For details, see the standards and scientific papers listed under References below. Preparing the Area where You will Use a Thermal Imaging System • Room temperature should be 68-76 °F (20-24 °C) and relative humidity 10-50 percent. • Try to control other items that could impact the temperature measurement: 1. Avoid reflective backgrounds (for example, glass, mirrors, metallic surfaces) to minimize reflected infrared radiation. 2. Use in a room with no draft (movement of air), out of direct sunlight and away from radiant heat (for example, portable heaters, electrical sources). 3. Avoid strong lighting (for example, incandescent, halogen and quartz tungsten halogen light bulbs). Conclusion Thermal imaging has been successfully used for medical diagnosis of vascular disorders. The temperature in the affected regions of patients with vascular disorders was low in the extremities due to obstructed arteries. However, in some areas it showed 0.7 to 1°C higher temperature than the normal areas due to inflammation and venous flow alteration. In general the thermal image findings were in good agreement with the clinical findings. However, the areas showing higher temperature contrast were noted not to be obvious in the clinical examination. This study demonstrates the usefulness of thermal imaging for medical diagnostics, with high reliability. EM

India has developed super capacitors using indigenous materials Introduction Power factor correction is the method to reduce the lagging power factor in inductive loads by fixing a high value capacitor across the phase and neutral close to the load. When the Voltage and Current are in phase with each other in an AC circuit, the energy from the source is fully converted into another form to drive the load and in this case power factor is in unity. When the power factor drops, the system becomes less efficient. As a rule a drop from unity to 0.9 in the power factor increases the current requirement to 15% or more. A power factor of 0.7% increases the power requirement to around 40%. This is much severe in the case of inductive loads such as Motors, Refrigerators and Inverters etc. In these inductive loads, current “lags” the voltage leading to “lagging power factor”. But opposite condition occurs if current “leads” the voltage. This is called “leading power factor”. Power factor correction is the method to reduce the lagging power factor in inductive loads by fixing a high

||www.electricalmirror.net||

value capacitor across the phase and neutral close to the load. These capacitors have leading power factor so that it will neutralize the lagging power factor of the load. Power factor correction has the following advantages. 1. Load becomes more efficient 2. Prevents wastage of energy though heat 3. Maintains voltage stability Being a cheaper product when compared to other components, and with the increasing need for energy efficiency, the demand for capacitors is rising rapidly. According to an Indian Electrical and Electronics Manufacturers’ Association (IEEMA) report, the Indian capacitor market registered a growth of 17.3 per cent during the first quarter of FY 2018-2019. Despite the wide application of capacitors, the Indian capacitor industry has very few manufacturers in the organised sector. One of the major concerns in the recent past has been the rising cost of materials, coupled with the falling market price

for the finished product. Prices of imported capacitors are lower when compared to what is available in the domestic market. Although the capacitor segment has seen relatively good growth, year on year, the actual volume of capacitors necessary to bring down the transmission and distribution losses is much below the required level. However, manufacturers are always on the lookout for new materials or variants of older materials that can be incorporated into passive components. Here’s a quick look at what’s new in the capacitor industry and the latest trends being followed globally. Current global trends Demand for ultra-capacitors: Experts believe that electrochemical double layered super capacitors (EDLC), also known as ultra-capacitors, will be in demand through the current year. Ultra-capacitors offer a very efficient, high energy solution, with high performance across a wide range of temperatures and a long lifespan with little to no maintenance. “Worldwide, efforts are being made to improve EDLCs for their high energy density. These innovative capacitors are used in transportation, grid scale energy storage, wind turbines, server memory, consumer electronics applications, etc,” shares SK Jain, managing director, Sumitron Exports Pvt Ltd. Higher capacitance value: According to A Bali, vice president, Deki Electronics Ltd, the current trend is towards smaller

ELECTRICAL MIR ROR

|| October 2021 ||

sizes in the high frequency environment along with the use of high capacitance value items. “A large capacitance means that more charge can be stored. Electrolytic capacitors are capable of providing the highest capacitance values of any type of capacitor. There are two types of electrolytic capacitors in common use—aluminium and tantalum,” he adds. Low equivalent series resistance: Moving along with the current trend towards lower voltage and higher current circuits, designers are now specifying capacitors with minimal ESR. Higher levels of functionality in today’s designs mean that despite the fall in voltage levels, circuit power levels should not drop. In simple words, a lower voltage means higher current levels. Thus, there is an increased demand on the power management circuit to deliver energy during periods of high current. Therefore, capacitors or capacitor banks that are used in the power management circuit need to exhibit low ESR characteristics. Multiple SMT electrolytic capacitors: With surface mount technology (SMT) picking up fast, capacitors for surface mount devices (SMD) are used in vast quantities. There are different types of SMD capacitors, ranging from the ceramic variety to the tantalum and electrolytic type. SMT low ESR type electrolytic capacitors are more in demand as they offer a combined solution of high capacitance, to supply energy during high speed load stepping, and low ESR to reduce the output filter ripple (noise) voltage.

liquid electrolytic capacitors offer high values of capacitance and low ESR that tends to be lower in cost, solid electrolytic capacitors feature reduced ESR, very high ripple current ratings and reduced size at a higher cost. Miniaturisation of capacitors: Miniaturisation is another new trend that is catching on. Miniaturisation of multi-layer ceramic chip capacitors has not only brought about reductions in product sizes, but also contributes to the efficient use of resources and saves energy in manufacturing, secondary materials, transport and customer processes. It has allowed customers to reduce storage space by about 80 per cent. Multi-layer ceramic capacitors: Increased adoption among design engineers across many industries has pushed multilayer ceramic capacitors into the mainstream in the past few years. Certain variants have even replaced tantalum type of capacitors. Faced with the miniaturisation trend, manufacturers are keen to develop smaller yet more efficient products. Shares Aloysius Ang, field application engineer, Murata Electronics (India) Pvt Ltd, “Multi-layer ceramic capacitors of 0201 size are going to be in the mainstream, led by demand from mobile phones and other portable markets. These capacitors are now being used in netbooks, e-book readers, gaming devices and other touch panel applications.” Global technological innovations Technological advancements are taking place worldwide

to make capacitors more efficient. For the fast supply of electrical energy, SuperCaps are being used. A SuperCap combines the advantage of conventional capacitors as fast suppliers of electricity with that of batteries as notable energy reservoirs. These capacitors take advantage of the charge stored in the electrochemical double layer and provide extremely high capacities of more than 1000 Farads. Explains C Satish, managing director, Filcon Electronics Pvt Ltd, “SuperCap modules are developed as a replacement to conventional batteries in a large number of applications. Their energy density is typically hundreds of times greater than conventional electrolytic capacitors. They also have a much higher power density than batteries or fuel cells.” Harmonics flow to capacitors causes overloading and possibly even premature failure in the production line. There is also a risk of resonance with any of the harmonics present in the system. In such a case, it can damage not only the capacitor but also other equipment in the line. It is, therefore, important to provide properly designed harmonics filters after carrying out an analysis of proper harmonics with different load conditions, eliminating the possibility of resonance, checking transformer fault levels, impedances, etc. Thus, these filters block the harmonics and improve the power factor. Moving ahead in innovation, Deki has been in the forefront of introducing new products into the Indian market. Informs a Bali, “Lighting being the main area of focus, Deki introduced its PES series and patented polyester self-healing (PSH) series. PES is a unique six film design, which helps to achieve better minimum breakdown with similar or smaller sized capacitors. PSH is yet another unique patented design that has an inductive construction with self-healing properties.” A wide variety of materials with dielectric properties that enhance energy density, frequency response, equivalent series resistance (ESR), equivalent series inductance (ESL) and temperature range are registering huge growth. EIA Class 2 dielectrics are being used in various temperatures and tolerance ranges, allowing manufacturers to produce capacitors for particular purposes. Multi-layer ceramic capacitors (MLCC) are an excellent example of such passive components that have enjoyed robust growth, through the use of a wide variety of dielectric materials and by making improvements in device design. There are many engineered dielectric materials that have been used in MLCC devices, which allow an array of devices to be built to meet specific design requirements.

R&D efforts are geared towards improving the electrical characteristics covering capacity density per unit volume, frequency response, DC bias voltage and loss coefficient. Increasing the reliability of capacitors is also a priority, especially among suppliers targeting automotive and industrial applications that demand rigorous operating attributes both in the temperature range and in voltage. Where does India stand? Despite its shortcomings, the Indian capacitor market— unlike the world capacitor market—is expected to grow by 10 to 15 per cent, annually. Domestic manufacturing lags far behind demand, as a result of which India has to import almost 60-65 per cent of its requirements for capacitors from China, who is the world leader in capacitor manufacturing and a small quantity comes from Taiwan, Korea and Japan. While the manufacturing sector in India needs a big fillip, it is important for manufacturers to follow the many new trends that have emerged in the global markets. India needs to attract more investment in this sector. “India needs to adopt a two-prong action plan—one is to increase R&D efforts to match international quality, and the second is to increase production volumes to meet the demand at lower prices,” shares S K Jain. Adding to this, C Satish feels, “For India to compete with the global players, it is essential that domestic manufacturers pay more attention to price and quality. This can only happen by automating production lines and moving ahead with volume production.” A major concern in the recent past has been increasing input material costs coupled with increasing price levels. According to Vikram Desai, managing director, Desai Electronics Pvt Ltd, “Worldwide DC plastic films capacitor market is expected to be flat or may even shrink by 5 per cent over next 5 years, provided the world economy does not shrink further. The demand for plastic film capacitors has now flattened out with deliveries matching the demand. The availability of raw material, especially metallised films, has improved with shortening of delivery times. There is a pressure to increase the prices, in light of the devaluation of the rupee.” There has been an upward trend in the Indian prices due to low volume production and increased manufacturing input costs. Hence, major EMS companies in India are generally procuring capacitors from foreign suppliers through their Indian distributors. However, when it comes to quality, domestic companies are doing far better than various other leading countries. Adds A Bali, “Today, cheap film capacitors are flooding the country but the discerning purchaser knows that buying from a domestic player is a much better option,

even if the price is 10 to 15 per cent more as there is the assurance of quality, flexibility and service.” India not only has the manufacturing capability but it also has global technology available within the country. “But electronics manufacturers are not using the latest capacitors—the capacitor sizes being used in India were in vogue 10 years ago. Indian manufacturers are still commonly using capacitor sizes of 0603, 0805, etc, which are usually more costly. Local manufacturers should speed up the progress to MLCC usage downsizing into 0402 size or smaller,” informs Aloysius Ang. India’s power sector is growing at a healthy rate and with the increase in the megawatts of electricity generated capacitors play a very important role in improving power utilisation. It is well known that India’s transmission and distribution losses are very high. Indian manufacturers must invest in the latest technology to cut these losses and meet the rising demand for capacitors in the country. What’s on offer in India?

materials for strategic use in defence and space sectors as an import substitute and to overcome energy deficiencies in critical equipment, a senior official said. "We have developed super capacitors of different voltage for specific use in defence and space equipment as they store more energy than ordinary capacitors and discharge faster than batteries," Centre for Materials for Electronics Technology (C-MET) director Arun Sachdeva told IANS here. The state-run C-MET, under the department of electronics

||www.electricalmirror.net||

and information technology, (DeitY) has developed the super capacitors under a pilot project at its Thrissur laboratory in Kerala and given them for trials to state-run defence and space agencies in the country as a power source for diverse applications. "Once we complete testing in trials and standardise them for strategic use, we will transfer the technology to the private sector for volume production under our supervision, as

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

they can also be used for industrial and consumer needs," Sachdeva said at electronics’ summit here recently. As super capacitors use electrostatic double-layer capacitance instead of the conventional solid dielectric of ordinary capacitors, they are used in applications that require rapid charge or discharge rather than long-term compact energy storage. "Besides defence equipment like battle tanks, radar-mounted vehicles and artillery guns, super capacitors can be used in space applications like satellites and launchers, as energy supply is critical for their operations," Sachdeva asserted. Super capacitors or ultra capacitors are also used in high-end cars, luxury buses, high-speed trains, heavy-lifting cranes and speedy elevators in tall skyscrapers as regenerative braking, short-term energy storage. As an autonomous scientific society, C-MET is mandated to attain self-sufficiency in electronic materials, components and devices for catering to the country's strategic and industrial applications with indigenous resources. "There is a huge market potential for super capacitors in the country as they can store 10-100 times more energy per unit than electrolytic capacitors and bridge the gap between electrolytic capacitors and rechargeable batteries, Sachdeva noted. The centre, which has two more labs at Hyderabad in Telangana and Pune in Maharashtra, had invested around Rs.2 crore-Rs.5 crore ($295,000-$738,000) to set up the facility for developing super capacitors of different voltage per unit volume or mass. "In the absence of a fab (fabrication plant) to make silicon wafers, we have to import them in the form of chips for making super capacitors, using graphene-based electrodes with raw materials like carbon aerogel," Sachdeva admitted. As storage device with fast charging ability, superior low temperature performance, long service, cycle life and reliability, super capacitors have the potential to replace traditional batteries and capacitors in a wide range of electronic applications for defence, space, automotive and renewable energy. According to a joint market study by the New Delhi-based Electronics Industries Association of India (Elcina) in partnership with the Mumbai-based multi-country market research firm IMRB, the super capacitor market worldwide is estimated to reach $8.3 billion by 2025, growing at 30 percent over the next 10 years.

"Super capacitor technology has not yet been commercialised in India and is not yet common in use due to high costs initially and low-energy density. Only C-MET is working on indigenous production of carbon aerogel-based super capacitors," Elcina president Vikram Desai told IANS on the margins of 'Electronics India Week', a three-day summit held here last week. When super capacitors are developed for use across industrial and consumer verticals and produced in volumes, they will become affordable by its makers and end-users spanning transportation, wind energy, solar energy, consumer electronics and strategic sectors like defence and space. The total addressable market for super capacitors in India is 1.3 billion units by 2020. In defence applications, the market size is projected to be Rs.20 crore-Rs.50 crore over the next four years. Tata Motors has been testing super capacitors for hybrid electrical vehicles, while three private firms - Spel and Chheda Electrical at Pune and Aartech Solonics at Bhopal in Madhya Pradesh are involved in developing them in the private sector.

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. Tripping of SC line on 3 Phase fault: One of the 132KV SC Line (Single Circuit Line) tripped on 3 Phase fault with tripping on both 52

Observations:

1. This line was connected between TWO Grid Sub-Stations, connected with source at both side station. 2. Fault on the line caused the tripping of both end with tripping indications of being 3 Phase faults. a. Fault indication at one end IR= 1.098 Kamp, IY= 1.076Kamp IB= 0.998 Kamp IN= 39 Ampere. With fault distance being recorded as 54.1 Km b. Fault Indication at the other end IR= 5.198 Kamp, IY= 5.098Kamp IB= 5.005 Kamp IN= 113 Ampere. With fault distance being ||www.electricalmirror.net||

c. 3.

b. c.

5. 6.

Technical Analysis:

1. This was of Lightning Effect and fault of 3 phase had been resulted. The detail explanation is explained below. 2. When Lightening does strike to any transmission line/ TOWER, Say here Tower as example, then the LIGHTENING which are of high frequency current tries to dissipate to ground on the possible EARTH connected paths (Earth wires for adjacent towers, own tower structures through Tower footings).

3. The earth integration plays the important role and due to its EARTH RESISTANCE/IMPENDANCE the current quickly dissipates without resulting any "BACK FLASH" ( Refer ||www.electricalmirror.net||

Fig 2.1.1) 4. In case of IMPROPER EARTH INTEGRITY, this high current on passing through the earth conducting path results POTENTIAL RISE at different terminals (voltage = L dI/dt). 5. In simper understanding we can say if TFR (TOWER FOOTING RESISTANCE) is high then before this phenomenon of Potential RISE on TOWER STRUCTURE shall be developed. 6. Now this POTENTIAL value say on one of the cross arm (R phase) happened to be 400KV(Example), then Potential Difference across the insulator string shall be (Example 400 - 76 = 324 KV). 7. Now this PD of 324 KV is well above the BIL of that STRING and hence very immediately the surrounding AIR MEDIUM does puncture being ionized resulted with FLASHOVER. This flash over we call " BACK FLASH" because Flashing is occurring from EARTH structure to LIVE CONDUCTOR. 8. Please note during or till to the phenomenon of BACK FLASH event, our RELAY available at Station does not actuate. This phenomenon may long last for maximum few micro-second. "So during LIGHTENING TRANSMISSION LINES NEVER TRIPS" 9. After completion of this BACK FLASH incident, the potential on Tower structure becomes ZERO. 10. Just after BACKFKASH event, the surrounding air medium being in conducting ionized condition shall be resulting of FRONT FLASH due to potential difference being 76 KV= 132KV/ root3. ( Refer Fig 2.1.2) 11. This voltage is of power frequency Value for which current from supply point rushes to the earth point as in case here tower structures. This is the fault current passes through Protection elements like CT, PT/ CVTs and on reflection to the associated relays and as per voltage magnitude, trips mentioning distance and all other parameters. 12. In practice such phenomenon of BACK FLASH and then FRONT FLASH does occur usually to one phase or maximum to second phase simultaneously. But effect on all phases is rare. 13. Now in this SPECIAL SITUATION: The incident had been such, the LIGHTENING effect is of high magnitude and on the way of current dissipation, the total tower had been resulted with POTENTIAL above the BIL of all the insulator stacks. So SIMULTANEOUS BACK FLASH had occurred and just ending of Back flash event and again due to front FLASH, the fault had been resulted. || October 2021 ||

recorded as 23.4 Km. The total distance of line being 75.6 Kms This was SC line with Triangular conductor configuration of R phase conductor on one side and Y and B phase on the other side. So, resulting of 3 phase faults were guessed as follows. Falling of external conducting wires on all the three phase simultaneously, which seems to be difficult as tower top is provided with EARTH wire and conductors are in triangular with on both side of the tower. Wild fire could be the other cause of tripping. But this possibility never occurs with all three phases simultaneous. Kite wire, farmer bird fastening wires, bird fault, tree touching etc.. could also the other cause of such fault. All the causes as described against point no 3 got overruled as this was even test charged after one minutes and charged successfully and loaded with required load causing the power flow from one station to the other. So, the fault is of TRANSIENT FAULT and vanished after certain time. The reason of being LIGTNING EFFECT was confirmed as it was resulting with thunderstorm and lightning during the period of fault occurrence. But 3 Phase Lightning Fault was not getting convinced as the conductors were displaced in triangular shape on available on both side of the tower.

C As e Stud y of the month

Case Study

The currents as per the source effect had been shared with one end being 1 Kamp and other being 5 Kamp with distance measurement being 54 Km and 23 Km respectively. 14. After one minute, all have subsided maintaining of Normal condition. So recharging and current drawl becomes normal as if nothing had happened.

Conclusion:

So for SC line TRINGULAR CONFIGURED conductors if such peculiar phenomenon does occur then cause could be " LIGHTENING EFFECT".

Recommendations:

The TOWER FOOTING RESISTANCE (TFR) should be maintained as low as possible to quick dissipation of lightning current. 2.2. Charging of 33Kv feeders on LOW IR value: One of the newly installed 33Kv feeder was planned for energization.

Actions Taken:

1. Statutory inspections were done regarding the installations, used instruments and electrical equipment in the system. 2. The protection schemes were checked and coordinated as per protection philosophy. 3. Pre-commissioning tests for all the equipment in the system were checked and all found in order. 4. The control circuits were also checked and found in order. 5. The testing/checking of the line on the day of charging was planned to be done. 6. Interesting observations were found on the megger value of the feeder just prior charging of the line. 7. The IR values were found very minimum with some Kohm against the values to come in Mohm or GOhm. (Refer Table 2.2.1) Table no 2.2.1 IR value of the 33KV LIne

2. The climatic condition was of cloudy and rain had been resulted before days. 3. The meggering had been taken during that cloudy day, though rain had stopped completely and day was with morning sun at around 9.30 AM. 4. The reason of obtaining the LOW IR value is due to the measurement of 15 KM overhead line during the morning time without allowing sufficient time for drying the line. The charging of the line was committed at around 10 AM, due to energization of the important area. 5. The decision was taken from the concept of the following a. Constant application of applied voltage of 5KV DC b. No fluctuation of this applied voltage of 5 KV c. The IR value in RISING TREND, indicating that the line does not have objectionable earth leakage path. 6. So, considering the values in rising point, allowed for charging. 7. The line was charged successfully and loaded accordingly as per load requirement.

Recommendations:

For IR measurement of Transmission line especially voltage upto 33 kV, the Voltage application and maintaining with constant value with IR value being RISING trend for few minutes irrespective of IR value, the decision of charging could be taken. 2.3. Abnormal Tan Delta Value of new AUTO TRANSFORMER: One of the new AUTO TRANSFORMER of rating 160 MVA, 220/132KV after release from the factory and after receipt at site, the TANDELTA VALUE as obtained were of very abnormal.

Observations

1. On receipt of the AUTO TRANSFORMER, assembly was done at site. 2. The oil filtration and other commissioning works were also done. 3. The LV tests like Voltage ratio, magnetic Balance, Excitation current and Loading stability tests were done and found in order. 4. The winding resistance, Turn’s ratio tests etc.. were also done at site and results were found in order. 5. But while doing TAN-DELTA TESTS, the results became irregular and abnormal. 6. So, suspecting problems in the testing kit, other test kits were brought for comparison of the test results and found with similar kind of irregular and abnormal value. 7. The results obtained by different kits are shown in the table no 2.3.1 below. ||www.electricalmirror.net||

8. The results as obtained conclude about some issue in the transformer, not in the KITs. 9. But some problems in the transformers are not being accepted as no other test results are supporting to this TAN DELTA abnormal value. 10. So experts were referred about such abnormality. 11. On visit the site and in the presence of experts and engineers from OEM, the test results were also taken for the TAN DELTA KIT. This time also the results were obtained of similar value as before. 12. This time it was suspected on the earthing of the transformers and especially on the CORE-BODY-YOKE connections. 13. The commissioning team was asked to produce the CORE-BODY-YOKE IR measurement value that has been taken during pre-installation condition. 14. The team explained that this value had not been taken during installation time. 15. The same has not even been asked by the testing team or the OEM requirement. 16. Now, the TOP COVER BOX was opened for the access of this LINK connection between CORE-BODY-YOKE. 17. It was found with looseness of the all the links on this box. 18. The required links were tightened properly and then the tandelta measurement was taken and found with the following results as mentioned in table 2.3.3. ||www.electricalmirror.net||

1. Due to looseness of the links between the CORE-BODY-YOKE, during the application of the HV AC supply of 10 KV to the specimen, it was found with contribution of Earthing for the measurement got changed. 2. The mode selected as GAR, GND and UST are not being properly maintained during the testing methods, so results as supposed to be obtained in the TAN Delta value are not normal as obtained before the measurement practices. 3. But after tightening the required modes got satisfied of producing the correct value as obtained in table 2.3.3.

Recommendations:

This is always recommended for keeping practice for measurement of CORE-BODY-YOKE, IR value before taking any installation of Transformer at site. The value should be above minimum of 25 Mohm. This value changes and kept as reference for different type of manufacturers EM

Automation provides tools that help in optimizing network design and performance 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 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 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. 62

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). The utilities then can takeactions more accurately, 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 ||www.electricalmirror.net||

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. Power plant operation involving intelligencefeatures through IT applications involvesautomation of manual operations, control ofsystems, data acquisition and logging ofinformation to fulfil requirements of versatility,user friendliness and cost competitive. 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 ||www.electricalmirror.net||

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 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 || October 2021 ||

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 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 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 ||www.electricalmirror.net||

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 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. ||www.electricalmirror.net||

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 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).

They are the most common type of UPS used for personal computers. The systems are considered as best value for personal workstations, however, for other applications, line interactive and online are better. For backup applications where low cost is critical, it doesn’t matter if the load loses power briefly and backup times are short, an offline solution is adequate, although it will not provide adequate protection against spikes or sags from the grid. • Line Interactive segment is growing significantly with a healthy CAGR during the forecast period. For typical applications where power often needs conditioning but is usually available and very short transfer times from grid to backup power are acceptable and daily energy consumption is a concern, Line Interactive is the preferred solution.

India UPS Market: Competitive Dynamics The India UPS Market is dominated by a number of players, amongst them, the major players are Consul Neowatt Power Solutions Pvt. Ltd, Delta Power Solutions (India) Pvt. Ltd, Eaton Power Quality Pvt. Ltd, Emerson Network Power (India) Pvt. Ltd, Hitachi HI-REL Power Electronics Pvt. Ltd, Microtek International Pvt. Ltd, Novateur Electrical & Digital Systems Pvt. Ltd, Schneider Electric IT Business India Pvt. Ltd, Socomec Innovative Power Solutions, Unlined Energy Systems Pvt. Ltd. Companies in this industry are following different strategies to strengthen their market position. A summary of 10 key UPS trends continues here with a discussion of new options related to compact designs and batteries, and a look at cooling requirements.

THIS IS NOT YOUR FATHER’S N+1 REDUNDANT UPS SYSTEM Traditional N+1 configurations required separate modules and a parallel cabinet with extensive field wiring between boxes. Now you can get from about 6kW up to 1.6MW in one UPS factory assembly or in one lineup and in a much smaller overall footprint. The new, compact arrangement has many advantages, but one drawback is you cannot always change out a problematic redundant component without risk or shutdown of the entire system. That’s because you’re essentially dealing with one assembly. All of the key components may not be internally redundant as they are with traditional N+ 1 configuration, such as individual module inputs and dedicated battery strings per module. But if the cost and size of an N UPS is almost the same as that of an internally redundant N+1 UPS, the N+1 system is often the better choice. This is particularly true if the initial load will almost always be such that you can take advantage of the internal redundancy. As an example, if an N UPS is rated at 90kW (one 90kW module) and an N+1 UPS is rated at 90kW (three 30kW modules), and your load will likely be less than 60kW, then the N+1 configuration will be the better choice. But if your load will likely be above 60kW, then the N configuration will be the better choice as it will include fewer failure points. N+ 1 system include many common failure points, especially when considering input and output switchgear, automatic transfer switches, etc. These common or single failure points can be largely designed out with 2N designs or variations of 2N or multi-bus designs. ||www.electricalmirror.net||

Multi-bus configurations (especially those with redundant components in separate rooms) provide the highest reliability and allow for easier and lower-risk end-of-life replacement. It is very difficult to replace a single bus UPS system without a planned shutdown or risk of an unplanned shutdown.

are often changed several times during the life of the UPS equipment. Therefore, when designing the space for UPS and battery equipment today with plans to add more UPS or more battery runtime in the future, you may not need to design and protect as much space for the future batteries.

Using internally redundant UPS systems allows for application of two systems to achieve 2(N+1) redundancy at a lower cost and size than most traditional N+1 configurations. If you’re up for the load balancing challenge, you can further reduce the amount of stranded capacity to achieve a high level of redundancy with three-to-make-two configurations, also known as 3N/2.

UPS COOLING REQUIREMENTS ARE BECOMING DYNAMIC

PREPARE TODAY FOR TOMORROW’S UPS BATTERIES Cabinet zed VRLA (valve-regulated lead acid) batteries remain the mainstay and account for roughly 30 percent of the UPS total cost. Look out, however, for the impending lithium-ion revolution. You’re already carrying around lithium-ion batteries in your laptop and mobile phone. Your car may be propelled by an electric motor and lithium-ion batteries. And if lithium-ion doesn’t begin to take significant UPS market share soon, some other emerging battery technology may well do so. Lithium-ion or other battery technology will likely require less space for the same runtime. Recharging time should be much faster and a common UPS failure mode — known as coup de fouet, or whiplash effect, which can result in UPS failure at the worst possible time, where the battery voltage drops deeply then recovers — should diminish, which may allow for shorter runtime requirements. All of this should not only further bring down the cost and space requirements for new UPS equipment and further improve reliability, but may also affect replacement batteries for existing UPS systems. On larger UPS systems, batteries

UPS systems, whether located inside the data center or (preferably) outside it, require reliable and often redundant cooling. UPS cooling has traditionally been sized based on a summation of worst-case conditions. These include full load and very low efficiency. But over-cooling UPS equipment is an increasing problem. UPS equipment that can experience large load changes or that can be operated in full online or in eco-modes (typically user-selectable) requires cooling that is much more dynamic than in the past. The UPS room cooling may need to reliably and automatically scale down from a worst-case 100 percent cooling function to as low as 5 percent. This dynamic cooling requirement means a simple, fully sized unit that is either 100 percent on or off probably won’t work. Today’s data centres depend on uninterruptible power supplies (UPS) to provide clean, continuous power throughout the facility’s entire operational life. While the mains supply is available, the UPS protects the data centre’s sensitive information and communication technology (ICT) equipment from electrical noise and any other power aberrations that may appear on the incoming power feed. If the supply fails, then the UPS battery must take over instantly and use its stored energy to support the load until either the mains is restored, or a generator can be started, or the data centre systems can be shut down safely. A UPS battery’s ability to store energy reliably and efficiently during normal operation, making it immediately available to the load during a mains failure, is critical to data centre

security. Accordingly, in this article, Mark Coughlin, Applications Manager for Reserve Power at EnerSys reviews the key battery technologies currently available, to inform commercial and technical specifiers responsible for battery selection.

The evolving data centre landscape

UP S & B a t t e r ie s

Data centres today experience a rising incidence of power outages and grid fluctuations caused by increased urbanisation and demand. Meanwhile, their workload is expanding, with a move to multi-user hosting services and larger data storage capacity requirements. These factors increase pressure for ‘best in class’ technologies and reliable power. UPS batteries are also directly impacted by reduced autonomy times, now typically between 30 seconds and 5 minutes, compared with historical averages of around 15 minutes. This is because of the shorter times needed to start up generators and switch loads. Fast recharge times are also desirable, allowing batteries to be recharged quickly in order to be able to support further power outages. Energy efficiency has become an overarching concern for all data centres, not just because of the financial impact of large-scale operation and rising energy costs, but also due to pressure from stakeholders – and legislation – to pursue effective carbon footprint reduction policies. Concerns about energy costs and grid power availability are driving growing interest in using UPS battery assets for energy storage applications, as a way to generate further revenue. In Firm Frequency Response applications, for example, UK-based data centres could provide battery energy back to the National Grid on demand. Alternatively, the batteries could be used for peak shaving, reducing data centre energy costs by supporting loads when electricity cost is high and then recharge the battery when low-cost electricity supply is available. Such strategies can bring significant cost savings, and generate money when supplying energy back to the grid. However, they demand longer battery autonomies than the five minutes typically needed for UPS backup. Currently, there are relatively few active sites deploying this strategy. Nevertheless, manufacturers such as EnerSys have conducted trials with batteries that can support these applications.

benefits and high visibility through its use in electric vehicles. Li-ion is attracting interest through being attributed with performance features superior to traditional Lead-Acid VRLA batteries, which are typically either gel or absorbent glass mat (AGM) designs. Compared to traditional VRLA equivalents, Li-ion offers a high cycle life, together with a significant size and weight reduction. Li-ion batteries also have high charge efficiency, with excellent partial state of charge tolerance – in fact, partial charge is preferred for long cycle life and operation in float conditions at full state of charge is avoided. The self-discharge rate of Li-ion is also low, which results in prolonged shelf life when in storage. Finally, it has well high and low temperature performance, and no gas emissions. However, Li-ion’s comparison with traditional VRLA reveals some challenges along with its benefits. Accordingly, we show how TPPL technology, as an advanced form of Lead-Acid chemistry, offers a number of advantages over traditional VRLA batteries. Despite historical cost reductions, Li-ion pricing remains a barrier for many users. With pricing depending on many factors including purchase volumes and the exact chemistry used, Li-ion is currently significantly more expensive than Lead-Acid. Furthermore, although space-saving may be important within data centres, weight reduction, which Li-ion batteries offer, is seldom critical. Similarly, the high cycling capability of Li-ion isn’t a driving factor for selection within UPS applications, where batteries are mostly floating at near full state of charge. While considered a safe technology, any Li-ion solution, unlike Lead-Acid, must include a battery management system (BMS) to ensure safe charging and discharging. This increases complexity, and requires users to have a thorough understanding of Li-ion technology. However, the BMS provides built-in diagnostics, which identify most problems and allow minimal maintenance. Additionally, consideration must be given to the MTBF (Mean Time Before Failure) of the electronic components factored into

Battery technologies and trends Battery chemistries currently available for UPS backup include Lead-Acid, Lithium-ion (Li-ion) and Nickel-Cadmium. There are also non-battery technologies like flywheels and Super-Capacitors. However, this article focuses on the two types that currently dominate the data centre industry: Lead-Acid, which represent over 90 per cent of the UPS market share, and Li-ion, which is attracting increasing interest due to its purported performance 80

Li-ion calendar lifetime calculations. Lifetimes of 15 years are claimed, but service life is not proven in the field. By comparison, advanced TPPL, with 12+ years design life, provides eight to 10 years’ service life, while traditional VRLA 10-year design life batteries typically provide five to six years’ service life.

centre vulnerability to multiple mains blackouts, through very short recharge times and time to repeat duty. For example, with 0.4C10 A charging current using fast charge methodology, TPPL can be fully recharged, following a one-minute discharge to 1.6 Vpc, in 2½ hours, and ready to repeat duty in 22 minutes.

Charging is another important consideration. Firstly, to fast-charge Li-ion, higher charging capacity, with increased cost, may be required. Also, in many cases the charging architecture would need to be replaced or changed to support different Li-ion battery charger voltages, so two different UPS rectifier types would be required across a data centre attempting to deploy both Li-ion and Lead-Acid batteries.

Battery replacement costs are also reduced through low internal corrosion rates, yielding a service life 25 per cent longer than for traditional VRLA. Additionally, storage life is increased from six to 24 months due to low self-discharge rates.

Above, we have seen why Li-ion, while attracting increasing attention, has been slow to penetrate to data centre market. On-going development driven by the powerful automotive sector may change this, but advanced TPPL technology offers data centre managers the best of both chemistries. As a Lead-Acid based battery technology, TPPL is reliable, well-proven, and easy to transport, handle and recycle. Crucially, advanced TPPL technology significantly improves energy efficiency, by providing up to 43 per cent energy reduction compared with traditional VRLA batteries through reducing float current requirements. Further energy savings accrue as it can operate, within warranty, at elevated temperatures, reducing air-conditioning requirements. Meanwhile, advanced TPPL battery technology reduces data

What of the future? Lead-Acid technology is expected to dominate the market for at least the next few years, although enquiries and niche projects suitable for Li-ion will continue to grow. In particular, applications requiring high cycling will be seeking advanced TPPL or Li-ion solutions. Depending on the application, Li-ion could be the preferred battery type. Nevertheless, before opting for Li-ion as the technology for a particular application, a full consideration of the requirements should be undertaken. The assessment should reflect the Total Cost of Ownership, with the benefits and challenges of Li-ion compared against other available technologies, including TPPL. Irrespective of the technology chosen, battery monitoring systems will become increasingly popular, due to the battery condition visibility and opportunities for predictive maintenance that they provide. This will also bring UPS applications into the increasingly pervasive Internet of Things (IoT) environment, making them visible as components of the larger data centre infrastructure.

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

Other factors, while not immediately specific to the data centre environment, should also be considered when selecting a battery technology. During transportation, Li-ion faces legislative shipping restrictions, while Lead-Acid batteries, including AGM and TPPL, are classified as non-hazardous for all transportation modes. Then, at end-of-life, Lead-Acid has an inherent value, and is about 95 per cent recyclable by a very well-established network of smelters; this possibility, however, is not mature for Li-ion.

Advanced TPPL technology is used today in many demanding critical applications. Data centre users can access TPPL through DataSafe XE batteries, which are specifically designed for UPS applications. They support autonomies of under five minutes, while offering all the above TPPL features.

Conclusion When selecting UPS modules to power critical loads in a facility, one key decision to make is whether to use a UPS with or without input and/or output transformers. See Figures 2 and 3 for notional diagrams depicting a transformer-based and a transformer less UPS module, respectively. Over the last decade, transformer less UPS systems have grown rapidly in popularity, eclipsing transformer-based designs. This transition is not surprising, as transformer less modules offer many advantages over a UPS with transformers. The largest advantage is efficiency. A UPS without transformers can see efficiency advantages of 5% or greater, as compared with those with transformers. Not only does this mean lower electricity bills, but it also represents lower heat loads in the room housing the UPS, resulting in reduced HVAC requirements. EM

Application of Marconite as a Good Ground Enhancement Material than Bentonite in Transmission Linesa Case Study. Abstract : The earthing system has an important role in safe operation of Transmission lines. In the hilly terrains generally the soil resistivity is very high and such areas are lightning prone. Lightning over voltage causes flashovers and subsequent tripping in transmission lines Reduction of grounding resistance is one of the efficient ways to prevent occurrence of such flashovers. The primary object of safe earthing design of a transmission line is to provide low resistance path to lightning current. 400 kV transmission lines of NETC traverses through areas having high soil resistivity (10–10,000 Ωm) and high isokeraunic levels, Soil is very acidic in nature in addition to other severe environmental conditions of North Eastern Region.

A. Major challenges in operation and maintenance of D) Bentonite transmission line in north eastern region:E) Marconite

E a r t h in g

The Operation and maintenance of transmission line in North Eastern Region is a big challenge due to following major constraints i) Dense forest, Hilly terrain, fast growing vegetation, Agricultural Cultivation fire (Jhoom Burning), pockets of open coal mines. ii) Frequent land sliding & road blockage due to heavy rainfall. The rain fall in NER is about 7-10 times more than all India average rainfall. iii) The acute ROW issues and theft prone area in some part of Assam,River scoring. iv) Severe lightning in some portion of line v) Land slide prone area.

Bentonite and Marconite are used as ground enhancement materials (GEM) to reduce earth resistance. NETC considered Bentonite due to its water absorbing feature over Marconite for improvement of lightning performance of Transmission line.

F) TYPES OF BENTONITE: Two types of Bentonite is commonly available • Sodium Bentonite. • Calcium Bentonite Sodium bentonite is having properties of swelling while calcium bentonite is non swelling in nature. NETC has used the sodium bentonite as it can absorb water up to 5 times of its original weight and swells up to 13 times of its dry volume.

G) BENTONITE CHARACTERISTICS B. To minimize the impact of lightning effect, following Bentonite usually forms from weathering of volcanic ash options were analyzed. with high content of silica. Swelling properties & moisture i) Providing additional earthing of towers through PG clamp with separate earth pit. ii) Providing spike on tower top to capture lightning strikes. iii) Providing one more additional insulator disc to protect against Back flashover. iv) Installation of Transmission Line Arrestors (TLA) in location where TFR value is more than 50 ohms. v) If the value of the soil resistivity more than 1500 ohms meter use of counter poise earthing up to 70 meter. vi) The Use of Morolite (Mixture of Bentonite with 7.5% salt) with 40 mm dia Galvanized pipe type electrode. vii) Addition of Salt & Charcoal with Rod earthing. viii) Carbon earthing. ix) Explored use of chemical earthing bentonite and marconite.

Marconite Characteristic and advantage over the Bentonite. i) NETC has explored the alternate option to Bentonite earthing in some of the locations by using the Conductive concreate earthing (Marconite conductive aggregate + Cement) as the Ground Enhancement Material and obtained better result. ii) The Marconite is Corrosion & Maintenance free product. iii) The life of the Marconite is 50 years as compared to the life of bentonite which is 4 to 5 years. iv) It is very low resistivity dissipate the fault current very fast. v) It did not leach away by ground water as a conductive concreate. vi) Marconite did not require the water / moisture for conduction of the electricity, as bentonite in which requires moisture for conduction of electricity. In Marconite, conduction of electricity is through the movement of the electrons. vii) Its pollution free and green product and is used by NETC as Innovative solution in T/L for first time in India. viii) The soil pollution has been reduced.

Lightning is a massive electrostatic discharge caused by electric charges in the atmosphere and resulting in a strike from cloud to itself. Lightening is a very high frequency signal and high voltage /current, Impedance of the line change, Whenever lightning strikes the top of a transmission tower or earth wire, a lightning current flow towards bottom of the tower and causes voltage rise to a tower which results in back flashover across the insulators of transmission line or causes phase to ground fault. The probability of flashovers can be minimized if the lightning current gets the least resistance path to ground, which can be achieved by reducing TFR. The various power utilities /railways/companies are using Marconite in their substations and proved very effective. C) TYPES OF CHEMICAL EARTHING Following type of Chemical earthing compound is commonly Earth pit does not require water periodically, thus saving of water resources . used for reducing the soil resistivity 84

Three of earthing have been used by NETC for earthing of transmission line i) Pipe earthing and ii) Counter poise earthing implemented in NETC line. iii) Pipe Type Earthing. Bentonite treatment in counter poise earthing of transmission line of NETC While implementing chemical earthing, sodium bentonite was laid at a depth of 900 mm using new galvanized steel stranded wires (10.97mm) with proper compaction by means of ramming of soil after every 400 mm back filling. In each leg approximately 500Kg Sodium bentonite has been used. The length of galvanized steel wire was kept up to 40 meters depending upon soil characteristics.

Length: 30 meters. Depth: 90 cms. Width: 30 cms. by manual means, removal of existing counterpoise earth wire, cleaning and rubbing (if any rusting found) of counterpoise earth wire, application of bituminous paint on the surface of counterpoise earth wire. (anti corrosive paint), setting of form box for putting of counterpoise earth wire and mixture, back filling of the trench with excavated soil (without stone mixed soil) and ramming of soil after every 40 cms back filling.

NETC successfully implemented the Pilot project of the Marconite where the Tower footing value improved. In location where the TFR value not improved the value will be more than 50 ohms the idea of installation of Transmission Line Arrestors (TLA) will be the good option. TLAs are installed on the conductors, electrically in parallel to insulator strings. In the event of lightning, instead of back flash over across insulator string, TLA conducts and provide path to the lightning current towards phase conductors. It not only avoids flashover but prevents tripping in the transmission line. It is worth mentioning that application of TLA nullifies any impact of higher tower footing resistance.

CONCLUSION AND LESSONS LEARNT Based on the above field experience, it can be concluded Performance of transmission line depends on the performance of the earthing. It is essential to reduce the tower footing resistance to minimize the tripping of line during fault condition & lightning stroke on transmission line. This paper mainly

aimed to discuss various measure to improve the Tower Footing Resistance by using Sodium Bentonite as a Ground Enhancement Material (GEM) & Marconite in 400 KV in Transmission lines the tower footing resistance (TFR) However, Marconite is better ground enhancement material than Bentonite, as it is specifically engineered product manufactured for earthing unlike Bentonite which is a natural resource and is obtained from mines. Marconite is environment friendly and is green product and performs for a longer time. In lightning prone areas where reduction of tower footing resistance does not improve performance of transmission line, application of TLA may be better option to reduce the trippings.
