The commercial application history of transformers dates back to the end of the 19th century. The world’s first full AC power system, built by William Stanley, was demonstrated using step-up and step-down transformers in 1886. The transformer played a critical role in the outcome of the so-called war of currents, tilting the balance in favor of Tesla’s AC vision. These transformers can be found wherever electricity is generated, transported and consumed – in power plants and substations, industrial complexes, skyscrapers and shopping malls, ships and oil platforms, locomotives and railway lines, wind parks, solar fields and water treatment plants. Their most important function is to transform or adapt voltage levels, stepping them up for long-distance high-voltage transmission from the power plant, and stepping them down for distribution to consumers. Key growth drivers in this sector include, Investments planned in power sector, Orders based on targeted power generation capacity addition, Orders based on capex from PGCIL & State T&D utilities, Orders based on total investment planned in T&D sector in 12th FYP, Exports and replacement demand, Development of inter-regional capacity, Export potential. The power and distribution transformers market in India is projected to grow at a CAGR of over 10% till 2020. The transformer market in India can be pegged at more than Rs. 12,000 Crores. PT contribute (45%) of the total market and DT (55%). Over the last 2 years, the market has grown at a very moderate rate at less than 4%, due to the slowdown of power generation capacity addition & T&D infrastructure expansion. Anticipating the huge domestic & overseas demand, the transformer industry in India has more than doubled its manufacturing capacity over the last 5 years. Transformer manufacturing capacity in India stands at ~370 GVA with capacity utilization rates hovering around 60-70% on an average over the last 5 years. Transformer overcapacity in the Indian market has led to immense pricing pressure scenario severely impacting the profitability of the market players. Overall the reforms in the power sector are expected to significantly affect demand for transformers over the next 4-5 years. On the other hand this month issue focused on selection of test & measurement equipment. The taking of measurements has been necessary since human beings first began trading with their neighbors. People make measurements for many reasons: to make sure an item will fit, to determine the correct price to pay for something, or to check that a manufactured item is within specification. In all cases, a measurement is only useful if it is suitable for the intended purpose. In this area we have answered to the most common questions that arise while selecting the test and measurement equipment. We hope you enjoy reading this Review special report.

ADB Releases $48 Million to Improve Assam Power Sector

Power Sector Growth may Get Pulled Down Due to Lower Demand

Asian Development Bank (ADB), the Manila-based lending agency, has approved a $48 million loan to boost Assam power distribution sector. The bank and the GoI on 7 November 2016 signed the loan agreement which would help Assam continue its drive to improve access to efficient & reliable power. For the Assam Power Sector Investment Program (APSIP), this is the second tranche loan of the $300 million multi tranche financing facility that was approved by the ADB Board in July 2014. The project will help Assam to enhance capacity & efficiency of its power distribution system to improve electricity service to end users. The first tranche loan of $50 million was signed in Feb 2015. This loan will help strengthen the state’s distribution system, improve energy efficiency and reduce AT&C losses. The project, which is expected to be completed by Dec 2019, will help APDCL which is Assam Power Distribution Company Limited to add an additional substation capacity, expand and improve medium voltage network, reduce system losses by 3% & enhance energy efficiency through renovation & modernisation of existing 33/11 kV substations. Part of the loan will be used to strengthen institutional capacity of APDCL through setting up independent meter testing laboratories, load dispatch centres and installing centralised uniform billing system to 1.2 million customers. With the Govt. of Assam providing counterpart finance of $12 million, the loan of $48 million from ADB’s ordinary capital resources makes up to 80% of the total project cost of almost $60 million. The loan has a 25-year term, including a 5-year grace period with an annual interest rate determined in accordance with ADB's Libor-based lending facility.

The growth of the power sector during the July-September quarter might be muted due to poor demand from discoms. This has resulted in decline in PLF of coal-based power plants to 54.7% in the Q2 while it stood at 59%, year-to-date. The demand for discoms is likely to be pushed back further with Ujwal Discom Assurance Yojana (UDAY) likely facing implementation delays. Analysts at the Religare expect NTPC to report flattish growth in thermal output and lower PLF. With a 27% fall in thermal power generation in Q2, JSW is likely to be hit by rising cost of imported coal & rupee depreciation. As far as the transmission sector is concerned, Religare expects PGCIL to report revenue growth of 26% and profit after tax growth of 27%, Y-o-Y, led by strong commissioning in 2016. JM Financial says NTPC’s earnings growth is expected to be in line with its regulated equity growth, but core return on equity would be impacted by lower PLF. JSW will be impacted by low PLF at its most profitable merchant plants. However, hydro-plant earnings will cushion this impact partially. According to Ashok Khurana, director-general of Association of Power Producers, “The progressive decrease in average PLF, from 69.93% in 2013-14 to 65.67% in 2014-15 and currently at 64%, along with lack of fresh long-term PPA opportunities, is a matter of great concern for genco’s. The problem is compounded further by the inordinate delay in announcing the coal allocation and usage framework as the earlier framework ended in Mar 2015. Looking at the surplus position of coal, the new coal allocation and usage policy framework should remove the restrictions imposed on coal usage, facilitate medium-term PPAs and allocate coal linkages for all PPA holders coterminous with their PPAs. The easing of coal usage restrictions will alleviate the stress to some extent.”

GoI to Launch up to $2 billion Clean Energy Equity

The govt. and 3 state-run firms will jointly set up an equity fund of up to $2 billion for renewable energy companies to tap into to help New Delhi meet its clean energy goals. Private and public companies will be able to dip into an initial amount of more than $1 billion starting next fiscal year. India's govt. hopes the Clean Energy Equity Fund (CEEF) will attract pension and insurance funds from Canada & Europe. Around $600 million of the initial pool will come from the National Investment & Infrastructure Fund, under the Fin. ministry, and the rest from state entities NTPC Ltd, REC Ltd. and the IREDA. PM Narendra Modi has set a target of raising renewable energy target to 175 gigawatts by 2022, more than 5 times current usage, as part of the fight against climate change by the world's third-biggest greenhouse gas emitter and to supply power to all of the country's 1.3 billion people. The programme will depend on getting as much as $175 billion in funding with 70% of that likely in bank loans and the rest as equity, sources said. The govt. reckons loans are not a problem but providing equity to investors may be difficult due to uncertainties over returns. "As we expand our clean energy capacity, there may be a shortage of equity next year," said the source.

Private equity is seen as risky in India but if the govt. itself creates a fund, that gives a lot of confidence. India's clean energy push was set back earlier this year when US solar company SunEdison filed for bankruptcy. The company is now looking to secure partners to see thru its planned India projects.

Lack of Reforms Created Huge NPAs in Infra, Power Sectors : FM Speaking at the BRICKS Economic Forum, Finance Minister Arun Jaitley today blamed the successive governments' inability to bring in reforms in the infrastructure and power sectors for the rising non-performing assets in the core segments. He said there are a number of sectors which have been impacted by the global slowdown, but some of these were hit more because of the absence of reforms. He noted that “there are at least 2 sectors (infrastructure & power) where we can't blame external factors. Our own inability to bring in reforms adequately in these sectors, I think, caused the difficulty in banks books". Elaborating further, the Union Minister said that in the infrastructure sector the key problem is the inability to adequately and quickly settle the disputes. While accepting that absence of reforms in state discom led to a stress in the power sector, Jaitley said, "I think the only silver lining is that the causes of the stress in power sector have been analysed quickly and correctly, and now we are addressing those problems." He said bringing reforms in the country has become more easier now than it was some years back. "I think there is a lot of maturity, which has come into the country's political system and this is noticed from the fact that reforming in India today is no longer as challenging as it used to be say 10/20 years ago," he said. It can be noted that most of the over Rs 8.5 trillion of dud loans of banks, a large chunk are their exposure to infra and power sectors. 14

Nevertheless, companies are still keen to invest in clean energy. Japan's Softbank Corp, Taiwan's Foxconn and Bharti Enterprises have pledged to invest about $20 billion in India's renewable sector. Global solar giants like First Solar Inc, Trina Solar Ltd and Fortum are also expanding their presence.

Power Sector Debt at High Risk : Crisil Ratings agency Crisil says “nearly Rs 1.34 lakh crore worth of debt on underconstruction & operational power projects are at risk”. As per Crisil estimates, around 17,000 MW of operational power projects with a debt of Rs 70,000 crore and additional 24,000 MW under-construction projects with a debt exposure of around Rs 64,000 crore are at high risk. These operational projects are those, which are facing the consequences of aggressive bidding for coal supplies or facing huge cost overruns, and those with gas-supply issues", Crisil Senior Director Sudip Sural said in a press conference. He said over the period, the credit growth to the sector will moderate to 5% over the next three years as compared to an average of 18% witnessed in the last 5 years. This is primarily because the discoms debt which has been the key components of this exposure, is going to go out of the banking system over a period of time and move to the fold of the state govt. because of the UDAY scheme. Also, fresh investments in the thermal generation will remain muted, while on the other hand capacity addition in the renewable space will give some fillip to the credit growth, he said. As far as delinquencies are concerned, Crisil noted, that while the gross NPAs in the sector have increased from 1.3% to 4.4% in financial year 2015-16, the stressed assets as measured by gross NPAs and restructured standard assets continue to remain steady at 14%. Crisil further observed that in the discoms space banking sector debt is expected to come down significantly over the next 3 years with UDAY scheme making increasing impact. What we will see is that state govt.’s will take over the principal financiers to discom. As per our estimates as of March 2019, of the roughly Rs 4.6 lakh crore exposure to discoms Rs 3.4 lakh crore would be coming in from state govt.’s, says Crisil. ||www.electricalmirror.co.in||

MNRE amends Grid Connected Rooftop & Small Solar Power Plants Program

The MNRE has issued the 2nd amendment to the guidelines for grid connected rooftop & small solar power plants program. In its earlier notification released in the month of March excluded commercial & industrial establishments in the private sector from claiming central financial assistance. In order to provide further clarity in this regard, the current amendment defines that the ‘Private commercial and industrial sector‘ shall include: • Companies registered under the Company Act 1956/2013 other than registered under Section 25/8; • Company/firms registered with central/state government authority (SIDC, DIC); • Company registered under Limited Liability Partnership (LLPs) Act 2008; • Partnership firm registered under Partnership Act 1932; • Shops and establishment Act;

CIL's Coal Supply to Power Sector Dips 3% in AprilSeptember

State run CIL's coal supply to power sector declined by 2.9% to 184.9 MT in the first 6 months of the current fiscal even as demand for the fossil fuel has started picking up. According to govt. Data the dispatch of dry fuel by CIL in the corresponding period of 2016 was at 190.6 MT. In Sep, CIL's coal supply declined by 11.4% 27.1 MT as against 30.6 MT in the same month last fiscal, the data said. Coal supply by Singareni Collieries Company (SCCL) during April-Sep period declined by 3.4% to 22.2 MT compared to 23 MT in the corresponding period of previous fiscal, according to the data. SCCL is a government coal mining company jointly owned by Telangana and the Centre on a 51:49 equity basis. Coal Secretary Anil Swarup had said last month there were no plans to cut down output because the demand has already picked up now. In Oct, the demand has started picking up for both coal and power sectors, the secretary had said. CIL, which accounts for over 80% of the domestic coal production, is eyeing 598 MT production in 2016-17. CIL has a target to produce one billion tonnes of fossil fuel by 2020. 16

deleted in the Institutional and Social Sector and organizations/ institutions registered under the Societies Registration Act 1860 and the Indian Trust Act 1882 has also been included for CFA subsidy as per the new amendment. Earlier, only not-for-profit registered organizations in the institutional and social sectors were eligible for claiming central financial assistance. This restricted a no. of institutions including health institutions, educational institutions, community centers, trusts, etc. from availing subsidy benefits thereby impacting promotion of solar rooftop sector. Hence, the current move to remove the ‘Non-for-profit’ barrier is expected to promote the adoption of solar rooftop at a large scale in the coming future.

Rise in Imported Coal Prices may Hit Power Sector : Report The rise in imported coal prices is likely to have a negative impact on the power sector value chain as higher rates create "volume and profitability pressures" on discoms that are not able to pass on fuel cost increase to end-consumers due to "political intervention". According to Ind-Ra (India Ratings & Research), historically, the ability of the discoms to pass on fuel cost increases to the end-consumers has been limited and delayed due to the political intervention in the tariffs. The discoms, IPPs with non-escalable fuel cost, merchant IPPs and ports relying on imported coal for the bulk of their volumes will face volume and profitability pressures, it said in a statement. The 60% rise in imported coal prices between April-Oct 2016 is likely to negatively impact the power sector value chain. The increase in imported coal prices was more pronounced in Oct 2016, wherein prices rose by 25% to around USD 85/t (tonne) from USD 68/t in September 2016," it said. The regulatory commissions can allow a pass-through of such costs by way of power purchase and fuel cost adjustment (PPFCA) since power purchase cost is an uncontrollable expense for the discoms, it added. However, anecdotal evidence suggests

that most state regulatory commissions have not allowed for such PPFCA adjustments on an actual and timely basis, which has led to an escalation in the power purchase cost of discoms, without a commensurate increase in revenues, the rating agency says in its latest report.. "Ind-Ra expects merchant IPPs which sell power through the merchant route to be impacted significantly since the prices on the exchanges/ bilateral trades have not moved up at the same rate - as the rise in variable cost of generation (25%) in Oct 2016, on account of the imported coal price increases. Thus leading to a significant compression in their gross margins, which have fallen to zero in Oct 2016. Hence the viability of merchant IPPs on imported coal is doubtful in the current price scenario," the report says. ||www.electricalmirror.co.in||

3,700 crore Lossin State Power Sector Assam state power sector is in a difficult situation, accumulated loss of the 3 public sector power utilities of the State stood with a staggering amount of around Rs 3,700 crore. The share of APDCL is around Rs 3,090 crore, while the share of AEGCL in this amount is around Rs 442 crore and that of the APGCL is around Rs 173 crore. This amount has been calculated since the splitting of the Assam State Electricity Board (ASEB) in 2004, when the power utilities started with a clean sheet. The splitting process of the ASEB, also described as the reform process, completed in 2007. But these utilities still continue to incur loss. Sources enumerate the non-remunerative tariff, higher T&D losses, lack of transparency in metering & billing activities of the APDCL, lack of accountability and wasteful expenditure as the major reasons for this. Also elaborating, sources said, the tariff awarded to

the power utilities by the AERC is non-remunerative. They are granted a low tariff compared to the cost of power they supply to the consumers. The T&D loss in the State’s power sector is also high. It is 26% at present. But the fact remains that the AERC has been fixing the T&D loss target to the APDCL and the AEGCL. Only the loss approved by the AERC can be passed on to the consumers. The rest of the loss must be absorbed by the APDCL and the AEFCL. For example, the AERC approved the AEGCL a transmission loss level at 3.64% for the financial year of 2015-16.The APDCL meter reading has a lot of flaws. It is one of the areas which need to be looked into seriously by the authorities. Moreover, accountability is not fixed in most of the cases by the power utilities. There is also pressing need to bring an end to the tendency of indulging in wasteful expenditure among many officers of the power sector.

Power Demand to Rise in Future : NTPC CMD Exuding confidence that Centre's UDAY scheme will help revive debt stressed discoms, NTPC CMD Gurdeep Singh said,electricity demand is going to increase in future. The central govt. had launched UDAY scheme to help discoms reduce debt & improve their financial position which ultimately helps them buy power required for their customers. They were unable to buy power from generating firms despite having demand from their consumers. Singh was addressing employees on 41st raising day of the company today at Engineering Office Complex at Noida. He also spoke about efforts of NTPC's to bring down energy charges by stopping import of coal, ensuring better quality coal through third party sampling and coal rationalisation. Speaking about Environment Management, he said NTPC has to ensure minimum impact on the environment from its

power stations and carry forward the slogan "Low cost Low emission" to maintain its position as a leader in the sector. NTPC is creating additional carbon sinks by planting one crore saplings during this financial year and the upcoming Telangana Thermal Power Project shall be most modern complying with the latest environment norms, he said. Inclusion of safety as a Core Values is to ensure safe practices in all areas of Company's operations, he added. Singh lauded Team NTPC's efforts for achieving highest generation on 9-Sep-2016, performance of Koldam Hydro project, start of work at Pakhri Barwadih coal mine, for being the first company to issue Masala bonds, Consultancy Wing for providing services to nearly 18000 MW projects in the country and construction of toilets for Swachh Bharat campaign under CSR. ||www.electricalmirror.co.in||

She said the decision-making with respect to allotment & execution of power projects should be time-bound to ensure that the state gets the dividends of increased power generation. "JKSPDC is presently looking after 23 hydropower projects with a total installed capacity of 1211.96 MWs besides four IPPs of 42.5 MWs. 4 projects are under implementation in the state sector with a capacity of 103.5 MWs and 3 major projects with an expected generation capacity of 3176 MWs are in the pipeline," JKSPDC Managing Director Shah Faesal says. "What we will see is that state govt.’s will take over the principal financiers to discom. As per our estimates as of Mar 2019, of the roughly Rs 4.6 lakh crore exposure to discoms Rs 3.4 lakh crore would be coming in from state govt.’s ," he noted.

Commissioner Secretary, Power Development Department, Dheeraj Gupta, briefed the Board regarding various ambitious projects in state sector like 1850 MW Sawalakote HEP, 390 MW Kirthai-I and 930 MW Kirthai-II which are at an advanced stage of appraisal with CEA. In a key decision taken in the meeting, the long pending contract allotment issue of the 93 MW New Ganderbal Hydropower Project will be referred to the State Cabinet, an official spokesman said. He said the Board approved the constitution of Management and Finance Sub-Committee under the Chairmanship of Deputy CM Nirmal Singh and Audit & Compliance Subcommittee under Chief Secretary B R Sharma for better oversight of the organizational matters pertaining to JKSPDC. It was also decided that besides PFC, other traders would also be explored by PDC for selling of 60%

power from Baglihar Hydroelectric Project Phase-II to get a competitive tariff, the spokesman said. He said it was also decided to approach Union Ministry of Power for allocation of power quotas from BHEP-2 to the neighboring states for guaranteed flow of revenue for servicing of the loan. Keeping in view the importance of JKSPDC for the state economy and to keep the tariff competitive, the Board agreed to refer the matter regarding the exemption of Water Usage Charges to the Finance Department for further examination, the spokesman said. He said the board approved the award of consultancy services for checking of design & construction supervision of 1500M long tunnel on access road to Sawalakote & 178 M long steel bridge over river Chenab to M/S Rodic Consultants who have been selected through a two stage competitive bidding process. A road tunnel from Power House to Baglihar Dam was approved to be executed through M/S JAL at an estimated cost of Rs 6.54 crore. This tunnel will facilitate better access to the dam in view of the challenging geology of the region, the spokesman said. He said the Board also ratified the equity contribution of Rs 460 crore released to Chenab Valley Power Projects Ltd. (a Joint Venture company of the JKSPDC).

Wind Power to Supply up to 20% of Global Electricity by 2030 The Global Wind Energy Council (GWEC) released its biennial Global Wind Energy Outlook, outlining scenarios where wind could supply 20% of global electricity by 2030. The report looks at four scenarios exploring the future of the wind industry out to 2020, 2030 & 2050. According to the report - By 2030 wind power could reach 2,110 GW, and supply up to 20% of global electricity, creating 2.4 million new jobs and reducing CO2 emissions by more than 3.3 billion tonnes per year, and attract annual investment of about €200 billion. And with dramatic price decreases in recent years for wind, solar and other renewables, a decarbonized power sector is not only technically feasible, but is economically competitive as well. New markets are developing rapidly across Africa, Asia and Latin America, supplying clean energy to support sustainable development. The report’s lead analyst Dr. Sven Teske says “Decarbonising the global energy system includes the transport sector as a major emitter of carbon. The market for electric mobility, both in regard to electric vehicles as well as public transport, will continue to grow significantly and with this electricity demand for the transport sector. Wind power is in a pole position to supply this future power demand making the 20

wind industry one of the key industries of the energy sector”. The new report examines the International Energy Agency’s central scenario from its World Energy Outlook, the New Policies Scenario, and is compared with the IEA’s 450 Scenario, the GWEC Moderate Scenario and the GWEC Advanced Scenario. The results show how the global wind industry will

deliver in terms of global electricity supply, CO2 emissions savings, employment, cost reductions, and investment. These 4 supply-side scenarios are then compared with 2 different scenarios for the development of electricity demand. Global wind energy installations totalled 433 GW as of the end of 2016, and the industry is set to grow by another 60 GW in 2016, the new report noted. ||www.electricalmirror.co.in||

To Attract Indian Investors Bangladesh Eases Its Business Rules

In a bid to attract more Indian investors across sectors, the Bangladesh govt. will towards easing rules of doing business, said Kazi M Aminul Islam, chairman of Bangladesh Investment Development Authority (BIDA) while addressing a group of delegates from the Confederation of Indian Industry (CII). BIDA is a high-powered govt. department in the Prime Minister’s Office in Dhaka. The neighbouring country is trying to improve its ease of doing business ranking by entering into the double digit league over a period of five years. A 17-member delegation led by Arun Misra, who is the chairman of CII’s eastern region investment taskforce, was making a three-day visit to the neighbouring country that began on November 8 and concluded on November 10. The meeting was attended by several leading businessmen of Bangladesh. “There is a huge scope to invest in the power sector of Bangladesh which is looking at improved technology

in distribution,” the FBCCI president, Abdul Matlub Ahmad told the CII delegation. Currently, Bangladesh imports around 600 MW of power from India. A few private Indian companies are also investing in Bangladesh's power sector. Matlub Ahmad, chairman of one of the Nitol-Niloy Group of Companies, said “local entrepreneurs were not only keen to work with Indian businesses, but were also ready to extend all possible support

Solar Energy to Power Agriculture Sector: Maharashtra Maharashtra govt. has drawn up a scheme to ensure power supply to the agriculture sector for 12 hours a day through feeder-based solar energy, said CM Devendra Fadnavis. So far10,000 solar agricultural pumps have been set up across the state, he said, adding 16 renowned CoS dealing in these instruments from across the world have approached the govt. to facilitate their installation. He was addressing a gathering of farmers, agriculture scientists and representatives of allied business groups after inaugurating the 8th edition of “Agro Vision” at the sprawling Reshimbagh Ground here. “Agro Vision” is a combination of exhibition, workshops and conference which provides an excellent platform for farmers and the agriculture sector to explore various opportunities. The event lastsfrom Nov 11 to 14. It was conceptualised to help farmers from Vidarbha, where a large no. of agriculturists have committed suicide due to debt burden & crop failure. Union Minister Nitin Gadkari, chief promoter of the annual farm fair, presided over the function. Giving statistics, Fadnavis said 94,303 pumps were cleared for installation in the last two years in Vidarbha followed by Marathwada (66,790), Western Maharashtra (48,000) and North Maharashtra (18,000). Under the scheme, farmers can use feederbased solar pumps instead of individually buying pumps. Fadnavis called on farmers to reduce input cost and enhance production and said agriculture is 22

now treated as a part of science and scientific farming is need of the hour. Productivity must be increased to make agriculture sustainable, he said. The govt. has decided to set up integrated textile units in 11 cottonproducing districts as part of its ‘cotton to fashion’ push, said the CM. Recalling the twin occurrences of drought and excess rainfall in the past, Fadnavis said due to various initiatives like ‘Jalyukt Shivar’, a water conservation scheme, farmers have succeeded in minimising the impact of scarcity. Situation on the agriculture front is improving since the last two years when the sector recorded a negative growth of 16% (2014-15). This year, the Government is hopeful of achieving positive growth of 5-10%, he said. Speaking on the occasion, Gadkari lauded the efforts of Maharashtra govt. in the farm sector and stressed on better use of drip irrigation. He said farmers opting for drip irrigation should get interest subsidy on crop loans. This year the yield of cotton and soya had been much better and farmers should earn good money.

While Misra, leading the Indian delegation, said “the commonalities between India and Bangladesh could be translated into creating bigger business engagements” “Bilateral trade has significantly risen in the past few years, but given the potential, it is low. We at CII look forward to working more closely with Bangladesh and create win-win situations for all,” Misra added. Indrajit Ghosh, director of Panorama Display Technologies Pvt Ltd, said his company was exploring opportunities to invest in digital display in Bangladesh. While Pradipta Mohanty, chairman of the Odisha-based Surendra Mining Industries Ltd, expressed interests in investing in the thermal and solar power sector, apart from collaborating in in mining operations.Except for some restricted sectors, Bangladesh allows for a 100% FDI.

In 5-yearsIndia to get Electricity from Offshore Wind Energy India will get electricity generated by wind-propelled plants installed in Gujarat & Tamil Nadu in about 5 years as part of the country's green energy development programs, an energy expert, said Mathias Steck, Executive Vice President and Regional Manager at DNV GL, an international renewable energy groupwhich has a 30-consultant team in India and made its entry into the Indian market in 1989. "It would take 3-5 years that we see commercial offshore winds projects in India. We are preparing India for offshore wind (and) providing MNRE a road map for offshore wind for Gujarat and Tamil Nadu," he said. A 100-megawatt pilot project will likely be installed in ocean off Gujarat in about 3 years, he said on the sidelines of the Singapore International Energy Week held last week. It is to kick start a new power

generating sector under the Facilitating Offshore Wind in Industry (FOWIND) programme funded by the European Union. A FOWIND consortium has done a series of report on wind conditions for wind-generated electricity and its integration into a grid along the coastlines of Gujarat and Tamil

Govt Plans to Boost Biomass Energy Minister of New and Renewable Energy Piyush Goyal held a meeting of top officials to consider increasing incentives to boost this segment. “We are thinking of a scheme to encourage setting up of biomass plants using agricultural waste, but I cannot say anything more at the moment,” said Santosh Vaidya, joint secretary at the Ministry of New and Renewable Energy (MNRE), told. The govt. already provides financial assistance of Rs 20 lakh per MW for setting up biomass power plants, and Rs 15 lakh per MW for co-generation projects by sugar mills (using sugarcane waste left over after juice extraction). Such plants cost around Rs 4.5-6 cr per MW, while generation expense is around Rs 3.25-4.00 per kWh. They are also entitled to concessional import and excise duties while acquiring equipment, as well as a tax holiday for 10 years. But unlike sun & wind energy, this segment has been languishing in India. At the end of 2015-16, the country’s total biomass power installed capacity along with co-generation units was 4831.33 MW, with another 1150 MW under construction. Capacity addition has in fact slowed in the past 3 years, from 465.6 MW in 2012-13 to 412.5 MW in 2013-14, 405 MW in 2014-15 and 400MW in 2015-16. Barring Tamil Nadu, Uttarakhand,Karnataka, Maharashtra, & Uttar Pradesh, no state added any biomass power or co-generation capacity in the last fiscal year. Rather, leading players like Orient Green Powerhave been trying hard to sell off their biomass power assets, as they are not profitable. ||www.electricalmirror.co.in||

Punjab has an biomass power and co-generation installed capacity of 155.5 MW, of which around 62.5 MW are in operation. In Haryana, the capacity is 45.3 MW. “The Environmental Pollution (Prevention and Control) Authority (EPCA) has been urging the Punjab and Haryana governments to set up biomass power plants since 2008 as one of the solutions to Delhi’s pollution crisis,” said Polash Mukherjee, researcher at the Centre for Science and Environment. “A target of 600 MW of installed capacity was set for Punjab years ago, but without any timeline. It has since been revised to 500 MW by 2020.” SIX more biogas power plants are under construction in Punjab which on completion will raise effective the capacity to 110 MW from 62.5 MW. “But even after these are completed, they will use up only around 1 million tonne of agricultural waste, which is just 5% of the 20 MT Punjab produces,” said Mukherjee. Haryana has not added a single MW of biomass power for the past 3 years. The main reason for biomass power's stagnation is that for many years the feed-in tariff offered by the states for biomass power was too low. Thus banks & financial institutions were wary of lending for biomass projects. Another big hurdle has been the absence of a regular supply chain, since agricultural waste is readily available only during the 2-3 post-harvest months after which it becomes increasingly expensive. The fragmented nature of farming in India also makes collection of waste difficult.

Nadu. FOWIND is supported by Euro 4 million grant from the Indo-European Cooperation on Renewable Energy programme and Euro 500,000 contribution through the Gujarat Power Corp Ltd (GPCL). The consortium, Global Wind Energy Council (GWEC), comprises GPCL, DNV GL, the Centre for Study of Science, Technology and Policy (CSTEP), and the World Institute of Sustainable Energy (WISE). The project is being implemented in close cooperation with Ministry of New and Renewable Energy (MNRE) and National Institute of Wind Energy. "Over the time DNV GL has been in India, we have looked over 50-gigawatt of onshore wind projects," he said, adding "this is a market leading position" as DNV GL works for a large number of clients in renewable energy projects. DNV GL is also looking at prospects in solar and tidal wave energies in India, Steck added.

Telangana Generates 3,800 MW Solar Power According to sources, Telangana has so far commissioned 3,800 MW of solar power and 100 MW of wind power, an official said here on Friday. The State has so far commissioned 3,800 MW of solar power. The solar policy of the State has been widely received and there was tremendous response to the tenders floated for 2,500 MW solar power. So far, 100 MW wind power has been commissioned and nine more locations have been identified to take up wind power projects," Arvind Kumar, Principal Secretary (Industries, Commerce and Energy), of Telangana said in an interaction with NITI Ayog Advisor Anil Jain. The NITI Ayog official met Kumar to discuss the integration of renewable energy into electricity grid by promoting coordination between the Centre and States. They also discussed interventions required to promote India as a renewable energy investment destination for achieving national renewable energy targets. NITI Aayog has been assigned the task of promoting India as a renewable energy investment destination, so that its target of achieving 175 GW can be met by 2022, it said. Kumar said the State govt. is planning to actively encourage renewable energy and go for Hybrid (wind and solar) generation in the Hyderabad Pharma City and NIMZ. The installed capacity in thermal power sector, which was around 8,000 MW now, would go up by another 9,000 MW by 2018 with the commissioning of Damarcherla (4000MW), Manuguru (1080MW) and NTPC Ramagundam (4000MW) plants, he said. Kumar asked the NITI Aayog to look into infrastructure constraints and suggest models which would encourage renewable energy and serve as a sustainable model for discoms (distribution companies).

India Japan Civil Nuclear Deal : What's in it for India? India & Japan signed a landmark civil nuclear cooperation deal, upgrading MoU on the issue signed at the last annual Summit here, a move that will boost bilateral economic and energy ties and facilitate US nuclear major Westinghouse plant in Andhra Pradesh. The two countries had reached a broad agreement for cooperation in civil nuclear energy sector during Japanese counterpart Shinzo Abe’s visit to India in Dec last year, but the deal was yet to be signed as some critical issues were yet to be worked out.The agreement would enable Japan to export nuclear power plant technology as well as provide finance for nuclear power plants. Japan's Toshiba has majority stakes in US nuclear firm Westinghouse that is building a set of 6 reactors in Andhra Pradesh and could provide technical assistance for the same. Hitachi also from Japan has stakes in GE which is also 30

proposed to set reactors in India. It is no secret that Japan does not want nuclear technology transferred to India to be used for military purposes. The pact could include a clause to halt Japanese cooperation with India if New Delhi conducts a nuclear test. Japan is the only country in the world to have suffered nuclear bombing. Plutonium made by reprocessing spent fuel in a nuclear power plant can be used to make nuclear weapons. It is understood Japan will permit India to reprocess spent fuel at designated facilities on the condition India accepts comprehensive inspections by the IAEA. Such “advanced consent” will be withdrawn, however, if threats to national security or issues regarding the protection of nuclear materials arise. Following agreement, the Japanese govt. will seek approval from the Diet to promote Japanese corporate

participation in building nuclear power plants in India. The deal inked after Modi-Shinzo Abe annual Summit made Tokyo first non-NPT signatory to have such a deal with Tokyo. It would also cement the bilateral economic and security ties as the two countries amid an assertive China. There was political resistance in Japan, the only country to suffer atomic bombings during World War-II, against a nuclear deal with India, particularly after the disaster at the Fukushima Nuclear Power Plant in 2011. Other nations who have signed civil nuclear deal with India include the US, Russia, South Korea, Mangolia, France, Namibia, UK, Argentina, Canada, Kazakhstan and Australia. Meanwhile among other issues the two sides signed MoU for infrastructure promotion in India besides strengthening anti-terror & maritime security partnership amid China's aggression in the region. ||www.electricalmirror.co.in||

transformer is a device that transfers electrical energy from one circuit to another circuit, operating on the principle of electromagnetic induction. In other words, Transformers are devices used to step-up or step-down voltage levels in power transmission and power distribution networks. A power transformer is installed at all substations, starting from the power generation plant to the last substation in the transmission network, before power distribution starts. The figure below illustrates specific points where power transformers are installed in a grid network. A basic transformer consists of a core that creates a path for magnetic flux, a primary coil that receives current from an AC source, a secondary coil that receives current from the primary winding and transfers it to the load, and finally, an enclosure that protects the transformers from dirt, moisture, and other damage. Transformers are basically of two types: power and distribution transformers. Power transformers are used for stepping up or stepping ||www.electricalmirror.co.in||

down the electric current voltage from generators. Distribution transformers are used for changing electric current voltage at various transmission stations and sub-stations. Analysts forecast the Transformer market in India to grow at a CAGR of 13.29% over the period 2014-19. The transformer industry is projected to post a healthy growth rate over 2016-17 to 2018-19, as the government targets 24/7 access to power. The rise will be on account of higher ordering from Power Grid Corporation of India and renewed demand from state distribution companies. The Transformer market in India can be segmented into 2 product segments: Distribution Transformer (DT), & Power Transformer (PT). The Transformer market in India is also segmented into three categories based on voltage levels i.e. 11kV-220kV, 220kV-400kV, and 400 kV and Above. Indian Transformer (T/R) Industry As discussed above a T/R is a voltage changer - used to either step down or step up power depending on

its installation base. There are largely 2 categories of T/Râ&#x20AC;&#x2122;s based on function (power & distribution transformers). Other special transformers that are differentiated on usage include welding, furnace, traction etc. Many players have the capability to manufacture up to 400kV, however with ultra mega power plants (UMPPs) coming up, need for higher rating T/Râ&#x20AC;&#x2122;s is required (765 kV rating transformers). A power transformer (PT) is installed at the generation site right up to the last substation just before distribution activities commence. This T/R is used to either step up/down power to match the voltage requirements. They are oil filled transformers with its range spanning from 11kV to 765kV. PTs would account for about 65-68% of the total value of the transformer industry. On the other hand, a distribution transformer (DT) is used to transfer power from a substation to the final point of consumption. The basic purpose of a DT is to provide end users with low-voltage power. DT could ELECTRICAL MIR ROR || NOVEMBER 2016 33

Cover Story

either be oil filled or dry type by nature, with range spanning from 1.1 to 11kV. Distribution transformers would account for the remaining 32-35% of the total value of the transformer industry. Also, a dry type transformer is used where there is space constraint & higher chances occurrences of fire. These are mostly used by industrial & corporate clients at hotels, software parks, high rise buildings, hospitals etc. These transformers are categorized as distribution transformers due to their nature of operation. (i.e. at end users locations) In India many players belong to the unorganized segment of the industry and cater to the smaller ratings DT demand. This is due to lack of infrastructure, testing facilities and technical skill sets available with them. However over a period of time many of these smaller players moved up the value chain and graduated to the higher rating transformers. Despite this the number of players qualified for the larger variants of T/R’s is still small to serve upcoming demand expected over the forthcoming years. The Indian transmission sector consists of three levels: interstate transmission, sub transmission and primary transmission. These three segments are classified based on their voltage class; interstate transmission level ranges from 220 to 765 kV, sub transmission level ranges from 33 to 220kV & below 33kV represents primary transmission. State Electricity Boards (SEBs) act as nodal points for execution of government projects as they are authorized to float tenders and allot contracts depending on the bidders compliance with various parameters. SEBs in the past accounted for 75-80% of the total transformer demand, followed by industrial (15%) & export demand (5-10%). Private segment demand has been from various power consuming industries viz steel, aluminium, cement, oil and gas, automobiles, engineering, mining and minerals, paper pulp, chemical and petrochemicals etc. Most of the transformer manufacturers cater to demand from SEBs, which forms about 70-75% of their revenues and balance is contributed from the industrial side. However, the case is reverse for Voltamp, which derives 95% of its revenues from industrial segment and the balance 5% from SEBs. Orders from SEBs are all tender based and the lowest bidder(s) (L1 only or L1, L2 and L3 bidders) bags it. Many SEBs had price preference clause in place for companies present in their region. However, now with the scenario becoming more competitive and many players entering the industry, SEBs are forced to be more price sensitive. Hence they are subscribing to competitive bidding route. Most of the projects are funded either by WB/ADB/JBIC. These tenders have an inbuilt price variation clause (PVC), which protects the bidders margins from vagaries in raw material costs. In the event of declining raw material prices, 34

purchasing party will stand to benefit as price of finished product will move in line with that of raw material prices. Bidders price their products as per the IEEMA price index, which is widely accepted by the industry. The IEEMA index has been successful in capturing any variation in prices of key raw materials. The bidding process takes about 8 months. First the bids are placed in the newspaper or website. Interested parties who are pre qualified will place their quotations along with the required technical specifications. This process takes about four months. After the bids are placed L1, L2 and L3 bidders are segregated from the lot. They undergo technical screening in order to check their compliance with the technical specifications. The tender will be awarded to the lowest bidder and also scores high on technical grounds. This process takes another four months. Order execution would depend on the type of order placed, i.e. power or distribution transformer. Usually the delivery period of DT’s is 1.5 - 2 months, medium sized transformer is 2 -3 months and PT’s would be 6 - 8 months. Key growth drivers Investments planned in power sector: India is expected to add 278 GW of generation capacity in the next seven years till FY22 including conventional and non-conventional energy sources. A total investment of Rs.13.73 lakh crore is planned for the power sector for 12th FYP, which is likely to fuel the demand for transformers. CARE has calculated the expected order inflow for T/R’s for FY16 and FY17 through below three methods: Orders based on targeted power generation capacity addition: Orders for transformers are based on requirement of 7 MVA T/R’s for 1 MW of power generation capacity. Considering the realizations of leading T/R manufacturers in the industry for different KV class transformers, orders of around Rs.13,070 crore are expected to materialize in FY16 - FY17 each. Orders based on capex from PGCIL & State T&D utilities : PGCIL has an annual investment plan of Rs. 22,500 crore and the share of transformers is expected at 7%, as per CARE estimates. Further, the aggregate annual capex plans of the discoms and transcos is expected to be around Rs.76,348 crore each during FY16 - FY17, if the same remains in line with FY15. However, considering the capex materialization rate of 11th FYP and track record of share of transformers in total orders, orders

of around Rs.14,794 crore from discoms & transcos are expected to materialize in FY16 - FY17 each. Orders based on total investment planned in T&D sector in 12th FYP: GoI has planned an investment of Rs.1.80 lakh crore for transmission and Rs.3.06 lakh crore for distribution sectors in the 12th FYP. Considering the capex materialization rate of 11th FYP and track record of share of T/R’s in total orders, orders of around Rs.14,024 crore for distribution & transmission sectors is expected to materialize in FY16-FY17 each. Exports and replacement demand: Exports for FY16 and FY17 are expected to be in line with FY15. Further, the transformers installed during 1985-90 are expected to be replaced during 12th FYP, considering average transformer’s life of 25 years. Method description

28 GW at the end of 11th FYP to 66 GW at the end of 12th FYP. India’s cross-border electricity transmission interconnection with Bangladesh, Nepal, Bhutan and Sri-Lanka is also being expanded, which is likely to boost the demand for transformers. Further, according to the Indian Energy Exchange, congestion between western and southern region transmission corridor restricted the transfer of electricity in southern region in March 2015. Thus, the integration of southern grid to national grid is expected to open up opportunities for equipment suppliers in T&D sector including transformers. Export potential : Export of transformers is expected at around 20% of FY15 aggregate turnover of Indian transformer industry. The global annual transformer orders are expected to be in the range of Rs. 1.86 to Rs. 1.90 lakh crore over the next few years. Indian transformer manufacturers have a nominal share of around 1.61% in the global demand and thus exhibit a good export potential, mainly in the lower kV segment. Indian transformer manufacturers witnessed improvement in financial performance in FY15, with

moderation in raw material prices and revival in order inflows. Amidst a few early signs of revival in performance and expected pick-up in demand, the outlook is expected to be stable in near to medium term. CARE believes that planned investments in power sector, replacement demand, export potential and development of inter-regional capacity is likely to sustain the demand of transformers in near to medium term. In light of the foregoing, the income of transformer manufacturers is likely to sustain in near to medium term. Further, moderation in inflation and expected reduction in interest rates has the potential to improve the profitability due to high working capital borrowings. It is believed that no incremental long-term debt would be raised considering the present surplus manufacturing capacity. However, extent of working capital borrowings would depend on timeliness of payments from state power utilities and private players. Going forward, enhanced share of private sector participation would be crucial to boost execution in power generation sector that leads to faster roll out of T/R orders. Overall, credit quality of Indian T/R manufacturers is expected to remain stable in near to medium term with a stable outlook on industry. Indian Transformer Market Size & Challenges The T/R market in India can be pegged at more than Rs. 12,000 Crores. PT contribute (45%) of the total market and DT (55%). Over the last 2 years, the market has grown at a very moderate rate at less than 4%, due to the slowdown of power generation capacity addition & T&D infrastructure expansion. Anticipating the huge domestic & overseas demand, the transformer industry in India has more than doubled its manufacturing capacity over the last 5 years.

Transformer manufacturing capacity in India stands at ~370 GVA with capacity utilization rates hovering around 60-70% on an average over the last 5 years. Transformer overcapacity in the Indian market has led to immense pricing pressure scenario severely impacting the profitability of the market players. India’s huge power shortage, need to ramp up power T&D infrastructure, economic slowdown of developed markets like Europe & North America and excess transformer manufacturing capacity in China has resulted in India being an attractive destination for transformer companies globally to tap the Indian market opportunity. Anticipating this, many foreign players are already in the process of setting up base in India. Over the last 18-30 months, new players have entered the market either through acquisitions or through setting up of facilities within India. A few notable examples (Canadian company, Hammond Power Solutions Inc. had acquired 70% equity stake in the Hyderabad based transformer supplier Pan-Electro Technic Enterprises Pvt. Ltd in Feb’ 2012. Chinese manufacturer, TBEA has set up transformer manufacturing unit in Gujarat in order to qualify for the bids from PGCIL). Power Generation Capacity augmentation and Power T&D infrastructure expansion to be in-line with Power generation capacity addition. According to the 12th plan, INR 1200K-1300K Crores likely to be invested in the power sector. This spending on the power sector is expected to be equally distributed between generation and T&D. Spending on Power T&D infrastructure is expected to boost demand for transformers Rajiv Gandhi Grameen Vidyutikaran Yojna (RGGVY) scheme to improve rural electricity infrastructure and rural household electrification. The electrification drive is expected to provide impetus to demand for distribution transformers. Increasing focus on Rural Electrification Accelerated Power Development and Reform Program (APDRP 1-2) in order to minimize Aggregate Technical and Commercial (AT&C) losses at the distribution level and improve the financial health of the State Electricity Boards (SEBs). Industrial sector growth, Replacement of ageing equipment. These reforms are expected to significantly affect demand for transformers over the next 4 to 5 years. • Inadequate supply of prime quality Cold Rolled ELECTRICAL MIR ROR || NOVEMBER 2016 35

Grain Oriented steel is the biggest challenge faced by T/R manufacturers in the country. CRGO requirement is completely met through imports; it is in fact challenging to assess the true quality of the material that is used by the transformer manufacturers in India. India needs 2.5 lakh tons of CRGO every year and an appalling 70% of this is scrap grade material. • On the other hand high failure rate of distribution transformers, is a big concern for the transformer industry in India. The average operational life of a transformer is between 25 to 30 years; however, transformers are known to be recalled for repair in as early as 3 years. The failure rate of DT’s in India is estimated at 10-15%. This is due to the low entry barriers in the DT market leading to unorganized players entering the market, and competing on the price factor. SEBs historically follow a L1 vendor selection criteria, which has led to proliferation of many small players, that compromise on the quality of transformers manufactured. • Financial Condition of SEBs - SEBs have been facing losses due to the supply of subsidized power to agricultural farmers, theft of power, and inefficient T&D infrastructure. This has restricted private investment in the power T&D sector, thereby reducing the quality of service from SEBs. This, in turn, is affecting the capacity building program and transmission of power. • Lack of testing facilities – The growth in testing infrastructure has not kept pace with that of production, both, quantitatively and qualitatively. Testing infrastructure available at India's premier agency, the Central Power Research Institute (CPRI) is proving short of demand. Manufacturers of large power transformers at times need to send their equipment for testing to overseas facilities like Korea Electro technology Research Institute (KERI) and KEMA which is expensive. Apart from this, huge logistical costs and lead times are also involved. Conclusion The Indian power & distribution T/R markets are highly dependent on investments planned by the GoI for the T&D segment and reform programmes like the R-APDRP Program, RGGVY and UDAY. These programmes, when fully implemented as scheduled, are expected to drive the demand for both power and distribution transformers. The Government of India currently plans to strengthen transmission lines and create a National Grid interconnecting the 5 regions (northern, southern, eastern, western and northeastern) through the creation of 'Transmission Super Highways;' this is expected to drive the demand for higher-rated power transformers. With T&D ||www.electricalmirror.co.in||

companies actively striving to reduce AT&C losses, the demand for energy-efficient transformers would get a boost. With huge investments proposed across sectors such as power, infrastructure, etc., the transformers market in India is slated for strong growth. The excess capacity in the Transformer industry in India, and entry of new players is further expected to increase market competitiveness. Market consolidation over the next few years is inevitable. According to "India Power & Distribution Transformers Market Forecast & Opportunities, 2020", by techsciresearch, the power and distribution transformers market in India is projected to grow at a CAGR of over 10% till 2020. Power transformers

contribute a major portion in overall market revenues due to their higher price points. Under the 12th 5YP (2012-2017), Indian government allocated US$ 200 billion for strengthening the country's power generation, transmission and distribution sector. One of the major developments underway includes the country's shift from 765 kV to 1200 kV power transmission. This, in turn, is fueling the demand for EHV and UHV class power transformer installations throughout the country. India is also focusing on use of alternative energy resources like nuclear and solar energy for power generation, which is expected to further boost transformer deployments in the country in the coming years.

Testing & Measurement Equipment

Selection of Measuring Instruments : The taking of measurements has been necessary since human beings first began trading with their neighbours. In addition to trading, early societies also needed to be able to measure to perform many other tasks. When people turned from leading a nomadic life to settling in one place, other measurements such as measurement of land and building materials became important. Our knowledge about early measurement comes from historians and archaeologists, leading us to realize that although the roots of many of the early units of measurement were the same, actual values and their application differed from country to country. Over time, the quality of measurements has improved because of the need for higher accuracy in many fields, as society has become increasingly technologyoriented. Length and mass were the earliest measurements made by mankind. According to some historians, the oldest standard of measurement of mass that can be traced is the bega, a unit of mass used in Egypt in 7000 to 8000 B.C. it is believed that the weights were probably seeds, beans or grains, which were used in conjunction with a rudimentary balance for trading. An example of this is the carat. This was the seed of the coral tree and was called Quirat in Arabic. It has now been standardized as 0.2 grams (g) and the word Quirat has been corrupted to the present day carat. The early length measurements were usually based on parts of the body of the king (the pharaoh). The measurement of length known as a cubit was probably conceived between 2800 and 2300 B.C. in Egypt. The word came from the Latin cubitum, meaning elbow, because the unit represented the length of a man’s forearm from his elbow to the tip of his outstretched middle finger. The cubit was later standardized in a royal master cubit made of black marble (about 52 centimeters (cm) long). This standard cubit was divided into 28 digits (roughly a finger width), which could be further divided into fractional parts, the smallest of these being only just over a millimeter (mm). For volume measurement, containers made out of gourds or clay were filled with seeds of plants. These seeds were then counted to measure the volume. The ancient Egyptians had a variety of volume measures. The most important of these was called the hen, which was about 477 cm3. The Syrians, Phoenicians, Babylonians and Persians also had their own units for volume measure. In the years following the early days of measurement, the Romans introduced measurements called the uncia and the mille. The uncia was the width of a thumb and the mille was the distance a roman soldier covered by walking 1,000 steps. The measuring instrument is the most important part of the measurement process and the selection of the instrument therefore has to be done carefully. If the selection is not correct, the result of the measurement may give a wrong indication, thereby leading to an incorrect decision. The selection of measuring instruments depends on the measurement to be performed. Generally, three characteristics are considered; these are: The range and magnitude of the parameter to be measured and the accuracy of the measurement. The resolution of the measuring instrument should be smaller than the minimum unit of measurement of the parameter. Lastly, and most importantly, the accuracy or uncertainty of the measuring instrument should comply with the accuracy requirement of the parameter to be measured. 38

More on instrument selection Selection criteria, as mentioned above, should generally be followed when procuring new instruments. However, in many cases the measuring instruments are already available. In such situations, action as described below should be taken. a. First, the parameter being measured should be examined to check whether the tolerance and the accuracy have been stated. Next, the measuring instrument should be checked to see whether the range and the resolution are appropriate for the measurement. Lastly, the accuracy of the instrument should be checked to see whether it satisfies the specified requirement. In cases where the accuracy of the measurement isnot specified, the instrument’s accuracy should be examined to see if it is better than one third of the tolerance. If it is, then the instrument selection was appropriate. b. If, however, the measuring instrument’s accuracy is more than one third of the tolerance of the parameter, then either of the following actions should be taken: • Replace the instrument with an appropriate one, if the present system of measurement is affecting the quality of the product resulting in rejection or rework at the subsequent stage of production; • Review the specified tolerance if the existing measurement system does not affect the product quality. This means that perhaps the close tolerance specified is not needed and hence the tolerance could be increased to accommodate the accuracy of the instrument. Calibration of Measuring Instruments : Calibration is the set of operations that establish, under specified conditions, the relationship between values indicated by a measuring instrument, a measuring system or values represented by a material measure, and the corresponding known values of a measurand. Measurement is vital in science, industry and commerce. Measurement is also performed extensively in our daily life. Examples are - Measurements for health care, such as measuring body temperature with a clinical thermometer, checking blood pressure and many other tests (Checking the time of day; Buying cloth for dresses; Purchase of vegetables and other groceries; Billing of power consumption through an energy meter). Accuracy and reliability of all such measurements would be doubtful if the instruments used were not calibrated. Calibration ensures that a measuring instrument displays an accurate and reliable value of the quantity being measured. Thus, calibration is an essential activity in any measurement process. Calibration fulfils two objectives: • It determines accuracy of the measured data ||www.electricalmirror.co.in||

• It provides traceability to the measurement Hence calibration is essentially the comparison, under specified conditions, with a higher standard, which is traceable to a national or international standard, or an acceptable alternative. Reliability of Measurement : Whenever measurements are made, it is with the objective of generating data. The data is then analyzed and compared with requirements so that an appropriate decision can be taken, such as to accept, rework or reject the product. However, unless the measurement data is reliable, decisions based on such data cannot be reliable either. Consequently, these actions contribute enormously to the cost of quality a manufacturer has to bear. For measurement data to be reliable, measurement should be: (1) Accurate (2) Precise (3) Reproducible. Variation in the measurement process: Even when all the factors in a measurement process are controlled, repeated observations made during precision measurement of any parameter, even under the same conditions, are rarely found to be identical. This is because of the inherent variation in any measurement process due to the following five basic metrology elements are picturized below.

Also estimating the measurement uncertainty needs: (1) A thorough knowledge about the measurement process and its sources of variation. (2) The accuracy and precision of the measurements performed (3) Integrity of the persons involved in the measurements and calculations. The measurement uncertainty in a calibration situation should be one third or less than the accuracy of the instrument under calibration. In a test situation, where compliance to specification is required to be given, the measured value expanded by the estimated measurement uncertainty should not exceed the limit of specification. Another method of estimating the variation in the measurement process is to analyze the measurement system and calculate the gauge repeatability and reproducibility. This involves designing an experiment in which three or four appraisers (operators) perform measurements on three or more samples using the same measuring instrument. Three sources of variation are thus identified and quantified. These are – (1) Gauge (instrument) variation (repeatability) (2) Appraiser (operator) variation (reproducibility) (3) Process variation (part-to-part variation).The variation in the results ||www.electricalmirror.co.in||

of each type of measuring and test equipment system is then analyzed. The objective is to find out whether the variation in the measured data is the result of variation in the product or the measurement system. Base SI units and Derived SI units: SI Quantity

Handling, Storage and Maintenance of Instruments : Handling and storage of measuring instruments is very important for the measurement process. If handling and storage of such instruments is not appropriate, even a robust one may malfunction or may give erroneous output. To ensure proper handling and storage, a system approach is the most suitable. A system for managing instruments comprises not only handling and storage but other elements as well, such as unique identification, safeguarding against adjustments and training. It is common sense to say that all measuring instruments should be handled carefully. However,

because of the varied nature of their shape, size, robustness, accuracy and method of operation, handling of instruments needs to be paid special attention. Normally, an instrument should be handled in the manner specified by the manufacturer. Sometimes, operational instructions contain steps on how an instrument should be handled. A measuring instrument should be handled in such a way that the instrument – (1) is not damaged through improper holding or slippage and fall during usage (2) Does not lose its accuracy and fitness for use (3) Does not become dirty and need frequent thorough cleaning. Sometimes, improper handling of an instrument is a source of risk and hazard to the operator of the instrument. In such cases, additional precautions should be taken for handling the instrument. One of the ways proper handling of instruments can be ensured is to appropriately train all the operators of the instrument. While handling is important, storage and preservation of a measuring instrument is equally important for it to continue to give reliable readings. Whenever an instrument is not in use, it must be stored in such a manner that there is no doubt about its accuracy and fitness when used the next time. For this, it is necessary to ensure that during storage, the instrument does not suffer any physical damage. Nor should environmental conditions be allowed to affect it during storage. The following aspects should be considered while deciding on storage of a measuring instrument – (1) The manufacturer’s instructions on storage and preservation (2) Prevention of mechanical shock and vibration (3) Locking of movable parts of the instrument, where possible (4) Covering of inlets and other holes to prevent ingress of dust (5) Using anti-static covers for the instrument (6) Use of moisture absorbent materials such as silica gel in the storage case or container of the instrument. All the above activities for maintaining a system of storage and handling of measuring instruments require documents as support. Procedures may be developed for performing some of the activities. Formats may be necessary to record observations. Examples of documents and records needed for maintaining the system include – (1) Records of unique identification of measuring instruments (2) The manufacturer’s booklet of instructions on handling, storage and operation (3) Procedures for handling and storage of specific instruments (4) Safety instructions for operators of instruments (5) Training notes for operators (6) Calibration reports (7) Records of breakdown, repair and maintenance of instruments. There could be other records and documents as well. These documents and records should be maintained appropriately so that they can be easily retrieved as and when needed. These records form valuable sources of information ELECTRICAL MIR ROR || NOVEMBER 2016 39

Testing & Measurement Instrument

for taking decisions regarding the utilization of measuring instruments. And since it is people who are going to store and handle the measuring instruments, the individuals involved should be provided with suitable training. This training should be in line with the following elements – (1) Training should be given to all newly recruited personnel in a laboratory (2) Training should be given on all the above elements of the system (3) Trainers could be the senior laboratory personnel, professional trainers or experts from the instrument manufacturers or suppliers (4) Such training should not be a one-time affair but should be conducted periodically. Measurement in practice (Precision, accuracy and uncertainty) : People make measurements for many reasons: to make sure an item will fit, to determine the correct price to pay for something, or to check that a manufactured item is within specification. In all cases, a measurement is only useful if it is suitable for the intended purpose. Consider the following questions : • Do you know how accurate your measurement result is? • Is this accurate enough? • How strongly do you trust the result? These questions relate to the quality of a measurement. 40

NOVEMBER 2016 || ELECTRICAL MIR ROR

When talking about measurement quality, it is important to understand the following concepts. Precision is about how close measurements are to one another. Accuracy is about how close measurements are to the ‘true value’. In reality, it is not possible to know the ‘true value’ and so we introduce the concept of uncertainty to help quantify how wrong our value might be. The difference between accuracy and precision is illustrated here. The idea is that firing an arrow at a target is like making a measurement. Accuracy is a qualitative measure of how close a measurement is to the center of the target – the ‘true value’. Precision is represented by a cluster of consistent measurements, but there is no guarantee that these are accurate. Accuracy is a qualitative term that describes how close a set of measurements are to the actual (true) value. Precision describes the spread of these measurements when repeated - a measurement that has high precision has good repeatability. Q: I need the best test equipment possible within my budget: What are my options ? A: This question comes up sooner or later, both for established companies and start-ups. The main options are to buy new, buy used, rent, or lease. Special programs are available to rent or lease with an option to purchase. However, if you look a bit closer and ask around, you will find that if you’re nimble, creative, and conscientious about

your expenses, your sweet spot may end up being a hybrid model, employing two, three, or more of these options. In fact, it turns out that a recent study by Frost and Sullivan shows that facilities, schools, colleges, and, of course, designers and test engineers are rethinking how best to meet their test and measurement equipment needs. While most still purchase their equipment, 25% rent or lease, and that number is growing by 3% per year. Q: Why should I rent or lease instead of just buying what I need? A: The fact that you’re reading this means you’re likely on a tight budget, solet’s get right to that: The primary reason to rent or lease instead of buying outright is budgeting and tax flexibility. If you buy a piece of equipment, it counts as an investment and falls under equity, so it does have benefits if you have the cash available. However, by renting or leasing, you avoid dedicating potentially large portions of your budget to one piece of equipment when you need to spread that cash around, especially if you’re starting out and setting up your first test bench. Also consider the balance sheet and tax implications: Purchases go under capital expenditures (CAPEX) while rentals and leases can benefit you through tax deductions under operating expenses (OPEX). Suggestion: Talk ||www.electricalmirror.co.in||

with your accounting department about this. Of course, there are other reasons to rent/lease. It helps you address short-term or specialized needs and with the market changing quickly, you get access to the latest technology. Also, you get free calibration and maintenance, so you avoid the expenses, headaches, and wasted resources that should be focused on your design, or production. Q: When should I buy, and should I go the new or used route? A: Buying is a good idea if you’re sure of having ||www.electricalmirror.co.in||

a longer-term need and will be using the equipment frequently. The last thing you want is a piece of equipment that was used a few times, and then gathers dust in the corner of the bench or lab. If you buy new, you get the warranties, of course, and fewer potential headaches down the road. It’s also a good investment with tax advantages, and it counts toward equity in your company; Taking the used-equipment route frees up cash for more equipment when first setting up a facility. It can provide good value as long as a well-known manufacturer made the

equipment. If you purchase from a well-known rental company or supplier, the equipment should come fully calibrated. Q: What’s the difference between renting and leasing, and are there different types of leases? A: While both are agreements to let you use a piece of equipment for a specific period of time, typically renting is usually for shorter periods (although long periods are available) and leases tend to be for one year or longer. There are also different types of leases: operating and capital. Again, talk with your accounting department about this, but note that a reputable rental/ leasing company will be able to steer you in the right direction. Q: If I rent or lease, who handles maintenance and can I be sure it always has the latest firmware? A: Yes, calibration, maintenance, and firmware updates are handled on all rentals and leases. However, it’s important to note that in the case of leases, when the manufacturer’s warranty expires, no additional maintenance is covered. Q: What criteria should I use to evaluate a rental or leasing company? A: Look for a company with a good variety of equipment and suppliers that have good technical support and educational resources, and offers try-before buy options.

Q: A:

they have been in business: are they established, experienced, and reliable? Do they have local account support for on-site demos, equipment pickup, and equipment delivery? Also, a good company will advise on financing options and help you decide on buy versus rent/ lease based on your long- and short-term needs, and offer sound financing counsel to get you what you need. I have lots of older equipment: Can I use that to help finance my next piece of equipment? Yes, all of the major rental companies offer a trade-in program. However, this is not necessarily true for leasing, since a lot of banks offer leases and they’re not interested in older equipment since they can’t market it. What about buying off-rent used/refurbished equipment online? The most important difference between buying used or reconditioned gear off the web versus working with a rental company with which you

Case Study of The Month

Various Case Studies on Operation and Control Schemes for Grid Sub-Station Contd.... 1. Introduction : For the last few months, the response of the readers to the case studies on various incidents is overwhelming. Hence this month we are again choosing the write up on similar kind of studies for developing the synchronisation 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 Immediate Tripping 100 MVA Auto Transformer on Initial Charging: - In one of the 220/132 KV Grid Sub-Station, while initial charging of 100 MVA Auto Transformer, the unit tripped after 5 minutes on Buch-holtz and differential operation. Observation: 1. After review of the test reports, the transformer was charged. 2. After 5 minutes, it got tripped on Buch-holtz and differential relay with certain abnormal inside sound. 3. The transformer was taken shut down for detail 44

testing. 4. On testing it was observed with no variation on LT supply test (Turn Ratio, Magnetic Balance, SC and OC test etc..) 5. From the IR and PI value measurement, except Tertiary (LT) to Body, other results were satisfactory. The IR value of this was OK but PI value was observed less than one. The Tandelta value was also found approximately of 1.28. Analysis:2.2. Difficulties for injection of current from Primary Kit: While injecting the current from primary side of CT, secondary being connected to an electrical circuit, it was observed with less injection of current, though the rating of the KIT was above the allowable value. Checking:1. The detail of the secondary electrical circuit was thoroughly checked and found OK. 2. The tightness of the total circuit at every connecting point was done. 3. After doing such also, the amount of current injection raised but not to the limit of requirement. 4. The kit specification was checked and found with kit burden of very less value. 5. The suitable rating of KIT was changed and injection done and found in order.

NOTE:- It may be noted that while injection of current to the secondary circuit, either burden of the circuit or of the kit has to be measured. 2.3. Drawal of low RMS current during dynamic test of CT : While attempting the short circuit test for 132 KV 800-400-200/1-1-1-1, LIVE TANK CT, it was observed with the drawal of around 33.1 KA RMS current, though the current injection secondary calculation was as per the value of 40 KA for 1 sec. Analysis: 1. The current testing value was 40 KA for 1 sec during the dynamic test. So according to the calculation, the current was injected to the CT. 2. It was observed with current drawal of initial value of approximately of 40.1KA, but reduced thereafter and RMS value became around 33.1KA. But the peak drawal was OK up to 100 KA. 3. On the next attempt, the calculation was raised for injection for the test with tentative initial value of 44 KA and test duration being 1.3 sec. This time the RMS value became approximately of 40.01 KA for 1 sec and test became successful. 4. Reason of such was analyzed and found with the followings a. This CT was of LIVE tank type with 2+2 primary turns. ||www.electricalmirror.co.in||

b. So during current injection the heat such produced would be the obstacle of raising current of required value. c. When the current was injected with certain higher value for slightly more time, then with of 2+2 turns, the current became OK. NOTE: It may be noted that, for the Short circuit dynamic test for LIVE tank CT, with more primary turns (more than 2), the current injection calculation to be done for more value to compensate the heat loss due to more number of turn. 2.3. Problem on slow closing of 132 KV SF6 breaker: It was observed with tightness on the slow closing mechanism during the closing of one 132 KV SF6 breaker. Analysis: Because of mechanical closing problem of 132 KV SF6 breaker, it was attempted for slow closing of the device by the slow closing mechanism. But it was found with tightness of the slow closing mechanism for closure of the breaker. The detail mechanical circuit was checked and found with SPRING MECHANISM IN CHARGED condition. The spring was discharged for attempt to the Slow closing of the breaker and this time it was observed with correct slow closing and slow riding of the latch on the mechanism. Then the problem was solved. NOTE:- It may be noted that while attempting any breaker for SLOW CLOSING through SLOW closing mechanism, the OPERATING SPRING MUST be in DISCHARGED condition. 2.4:- Drawal of more current on 220 KV line with lesser MW flow: It was observed with following current and MW drawal on 220 KV line of 101 Km. (Current 60 Amp, MW 2.5 MW). Analysis: This line was of 101 KM long that offers more line capacitive reactance. The case as described above was equivalent to the ferranti effect condition under the situation of low MW loading on the line. So the charging current (Reactive current component) being more on the line as compared to the active current, the MVAR ( Reactive Power) became more and observed with value of 22.71 MVAR. Actual current measurement on the ammeter records the current drawal due to the MVA power involved in the circuit. Hence due to more MVAR power on the circuit, though the MW was less, but current recorded by the ammeter became more. NOTE: - Current drawal on the actual Transmission Line has to be considered on the basis of MVA power involved on the line not on the basis of MW. 2.5. Tripping of 132/33 KV Transformer on differential Relay: During running condition of a 20 MVA 132/33 KV, two winding Transformer, it was 46

NOVEMBER 2016 || ELECTRICAL MIR ROR

found with abnormal tripping on differential relay. Action Taken: 1. As the tripping was only on differential relay with no mechanical relay actuation, it was confirmed regarding the problem on the electrical circuit. 2. This problem may be on the CT circuitry or DC protection circuitry or due to the problem on the differential relay in the system. 3. The detail circuit was checked, load stability was done, DC tripping circuitry was also checked and found in order. 4. Finally the relay was checked and found with the problem on Static electronics circuit of one unit i.e R phase. 5. This unit was changed with the correct one and transformer was charged and stood OK. NOTE: It may be noted that for any tripping of transformer, only on electrical relays with no any mechanical relay, then the problem may be due to external electrical CT circuit and in the relay circuits. 2.6. Change of sign bit for current ratio error on PS class: While taking the turn’s ratio error for PS class (Special Protection Class) by current injection ratio meter with ZERO burden, the sign bit of the reading becomes reverse as that of the reading obtained by the use of turn’s ratio meter. Analysis: While measuring the % current ratio error by any CURRENT INJECTION RATIO meter, it compares the current on the load (on the burden) to that of the current injected to the primary winding. So the sign bit during comparison does not change due to current direction being same for both injection to CT and current on the load (Refer Fig 2.6). But for the case of non use of burden ( Load) i.e ZERO BURDEN, the current direction on the on the secondary side of CT gets considered and due to its direction being reverse than that of the direction of injection current on the CT, sign bit becomes reverse (refer Fig 2.6).

As shown in fig 2.6, the current direction is same for the use of BURDEN. So for this type of meter while doing the % ratio, the sign bit gets considered same as obtained in the reading display (the use of burden is generally considered for the metering core of CT). But for the case of PS class with no BURDEN on the circuit, while % current ratio error is taken, the current direction as shown on secondary of the CT becomes reverse and accordingly the result is taken as reverse than that of the sign bit obtained in the display. But for the case of TURN’s RATIO meter, the calculation does not take the direction of current and gets considered on the basis of nominal value of current and rated current. Calculation is done as per the formulae below % ration error= (Kn- N) x100/N The value comes on the basis of Kn i.e if this value comes less then % ratio becomes –ve and for the case of Kn being more than that of nominal ratio, it becomes +ve. Note: Confirm the type of meter used for % ratio measurement of CT, accordingly the sign bit has to be considered for the result. 2.7. Difficulty during current injection to CT:- While attempting current from a primary kit, it was not injecting the rated current to the testing CT, though the capacity of the kit was above the limit of the rated current. Attempts taken:- The connection from the KIT was thoroughly checked with tightness of the connecting leads. The resistance of the current carrying path along with testing leads were also measured and found within the limit of < 1 ohm. Then it was attempted for injecting the current with testing leads being in twisted manner. There were in use of 8 nos of testing leads with 4 nos from each of the current injection point as GO and RETURN current from and to the KIT. During this attempt, the current of required rating could be injected from the kit. Analysis:- On the initial attempt, as the testing leads had been taken with all the similar current carrying paths, the mutual flux from the higher current injection was causing the attraction magnetic field ( ref fig 2.7-a) and electromagnetic currents such produced out of it , were becoming hindrance to the actual current flow from the KIT. So the current injection was becoming difficult to attain the rated value of the CT. But while attempted with twisted and

The Potential of Technology to Improve the Performance of Major Projects Despite substantial investments, the construction industry is struggling to gain the full benefits of technologies including advanced data and analytics, mobility, automation and robotics. That’s the key finding from “Building a technology advantage – Global Construction Survey 2016”, the annual state-of-the-industry report from KPMG International. The construction industry’s contribution to the gross domestic product (GDP) in the developing countries like that of in India is about 10%. Under the Make in India scheme, it is expected that $1000 Billion investments for infrastructure sector would be accomplished in the next few years. Today the construction industry is one of the most unpracticed fields in terms of automation. The importance of construction automation has grown rapidly in developed countries. In developing countries like India, the construction industries need automation technologies such as new machineries, electronic devices, automation of road, tunnel, and bridge construction; earthwork, etc. The industry is constantly widening its vision and raising its game. Buildings are getting taller, our search for natural resources is taking us deeper, bridges are spanning longer, and the pace of change is such that technology projects are virtually obsolete as soon as they’re completed. Operating at the forefront of some of the world’s greatest challenges, construction is becoming greener and more sustainable, while continuing to improve social conditions and tackle human and natural disasters. Technology plays an integral part in helping the industry realize these goals by enabling enhanced design, planning and construction. When applied effectively, technology can significantly boost a sector that for many years failed to improve productivity. Yet, despite substantial investments in innovation, the construction industry is struggling to reap the full benefits of advanced data and analytics, drones, automation and robotics. The construction industry being labour intensive requires more numbers of skilled labour, good quality of work, and increase in productivity etc. The problems associated with construction work such as decreasing quality of work, labour shortages, and safety of labour and working condition of projects can be overcome by new innovative technologies such as automation which has the potential to improve the quality, safety, and productivity of the construction industry. Today, it is evident that the level of automation in construction is very low in comparison with current technological advances. That is why we must make new efforts to increase the automation level of this important sector. While technology advances are transforming other industries like retail, media, and auto manufacturing, the majority of construction companies operate much the same way as they did 20 years ago — relying on manual, disaggregated, and redundant processes for project planning and management. By rethinking how the enormous amount of data generated on a complex project is captured and leveraged throughout the project Source, KPMG, Global Construction Survey 2016 lifecycle, construction owners can achieve positive outcomes.

One of the critics highlights the power of “predictive analytics to determine how design issues impact constructability and provide warnings.” While another suggests th at “technology that addresses and pre-empts geotechnical conditions would help address major risks like tunneling.” Yet another talks of the potential for “sensors inside helmets to monitor safety, productivity and personal health.” Automation can overcome many of the delays that unnecessarily hold up projects, like statutory clearances and road permit issuances. But often these benefits seem frustratingly out of reach. One obstacle is the role of the CIO and other technology professionals. Too much of their time is spent on IT infrastructure-related issues, and not enough on exploring the potential of technologies like drones, automation and robotics, and getting involved in key investment decisions for these and other innovations. Many companies show a lack of discernment when purchasing technology solutions — and compound the problem with weak implementation. System platforms are often configured and installed poorly; in effect they’re set up to simply run like the legacy system they’re replacing. Without change management or re-engineering, it’s very hard to get the most out of a new tool. To complete the vicious cycle, the entire initiative is soon labeled a failure, further undermining the adoption of future technology. If owners and engineering and construction companies want to reverse these negative cycles, they need t o establish a clear technology strategy, with defined objectives and decision-making roles and criteria. Roads & Runways construction, Structures, Buildings construction, Ports, Tunnels, Factories and industries are areas of automation in Construction Industry. Some of the key advantages of automation in construction is as follows.

||www.electricalmirror.co.in||

Automation in construction industry may achieve the following advantages: • Uniform quality with higher accuracy than that provided by skilled workers. • Making tasks that are beyond human capabilities easier. • Replacing human operators in tasks that involve hard physical or monotonous work. • Replacing humans in tasks performed in dangerous environments such as those with heights, over a river etc. • Increasing productivity and work efficiency with reduced costs. • Improving work environment as conventional manual work is reduced to a minimum, so the workers are relieved from uncomfortable work positions. • Economic improvement. Automation can serve as the catalyst for improvement in the economies of enterprises or society. For example, the gross national income and standard of living in Germany and Japan improved drastically in the 20th century, due in large part to embracing automation in construction and infrastructure development. Visualization is the future of decision-making in capital projects Rapid adoption of visualization means that virtual ‘tours’ of construction sites will soon become the norm, offering short videos that provide a high-level picture of what’s going on — and indicating where the most urgent action is needed. These visuals are integrated with key project analysis using graphs, data trends and 3D graphics, giving management a single version of the current and projected state. Owners, engineering and construction companies, consultants

and project managers are more frequently using camera-mounted radio-controlled ‘quad’ devices (quad-cams) which can give a 24/7 real- time view, to monitor and survey overall progress of their construction activities. They can identify potential hazards or quality issues and are particularly useful on sites that are large or spread out. Quad-cams are ideal for reviewing and recording the performance of large cranes and associated lifts, as well as materials movement and erection activities. When combined with the right information at the right time, debottlenecking becomes easier and not just about productivity, but overall throughput of the project increases. The analysis can help managers plan out the optimum routes for large shipments, avoiding tight turns or low-voltage crossings and thereby enabling the wider value chain outside of the site to integrate with the wider supply chain. As with all breakthrough technologies, the use of quad-cams will evolve and become mainstream, and should make a huge contribution to project efficiency and ultimate success. Automation and robotics in construction (ARC) has the potential to relieve human workers from repetitive and dangerous tasks, and has been extensively promoted in the literature as a means of improving construction productivity and safety. Compared to the tangible benefits of automation and robotics identified by the manufacturing industry, the construction industry is still exploring feasible and broadly deployable ARC applications. This can be attributed to several commercial and technical challenges. Serious automation and robotics in construction technology continues popping up in pockets of excellence worldwide. Shanghai, Los Angeles, London, Amsterdam, Barcelona, Stuttgart, Rome, just to name a few, are putting forth some marvelous machines that just might redefine

building and home-tech construction much sooner than anticipated. Two have engineered government contracts (Los Angeles and London); some are putting up structures on spec; others are hoping to engage investors in order to go mainstream with commercialized products, and still others are doing it to either refine their machines or out of love for their craft. Maturing quickly, these nascent construction tools, are taking their first baby steps in the direction of building sites worldwide. A bit of consolidation among the varying groups and their technologies, which presently seem more than a bit remote, could certainly hasten a new era of construction. An era that stamps a whole new look to traditional industry bugaboos like frequent cost overruns and low rates of productivity. The benefits are just too startlingly good to ignore - (1) It radically reducing construction costs, (2) Increasing construction speed, (3) Little to no building-site construction waste, (4) Reducing financing costs for builders because the product is ready for market much quicker, (5) Easier and safer work for construction workers, (6) Lower insurance costs for builders (7) Increased sustainability over 50

a building’s lifetime. And there is no question that builders would benefit from robotics. As much as executives in any segment of the economy, they need to cut their costs, boost their productivity and make workplaces safer. Indeed, construction’s need for automation and robotics will become urgent. Someday Building Teams may look back on today’s construction methods and wonder how we ever got along in the dark ages before bricklaying robots and self-assembling buildings. Or maybe that day is today. A look at construction technologies in development suggests a near-term revolution in how we build and operate our facilities. A few of these seemingly futuristic technologies are already commercially available and in use today, including 3D printing, unmanned drone aircraft, and robotic construction systems. One of the most successful areas for applying automation and robotics has been at the building envelope. Some forwardthinking building enclosure designs practically work like animal skin, adjusting their shading and vents to changes in ambient humidity, temperature, and light. Biomimicry is a common influence on these active or dynamic facades, which incorporate moving

NOVEMBER 2016 || ELECTRICAL MIR ROR

parts, sensors, and actuators, often tied to the central building automation system. Properly designed, active facades better regulate interior conditions and reduce energy loads for lighting and HVAC. A handful of real-world examples exist, but experts see broader adoption as unlikely, mainly because of high cost and a strictly long-term proposition for ROI. Overall, the advantages of use of automation in construction industry seem to outweigh the disadvantages. It can be safely said that countries that have embraced automation enjoy a higher standard of living than those that have not. At the same time, a concern is often aired that automating tasks takes jobs from people that used to build things by hand. Regardless of the social implications, there is no doubt that productivity increases with the proper application of automation techniques. The importance of implementing automation technologies is the need of today’s infrastructure project and construction firms in order to increase the productivity and good quality of work. Both small and medium size firms require automation technologies partly or fully to implement in different sectors such as design, planning, on site construction etc. ||www.electricalmirror.co.in||

Water has become a vital resource for economic growth and sustainable development. Southern India is currently engaged in conflicts involving shared water resources. The recent massive agitation witnessed in Bangalore & almost the entire state of Karnataka for sharing of Cauvery waters, that too, during the current Monsoon failure , the fragile water situation in Southern India is once again exposed. The issue has become more complicated and intense due to the displacement of local farmers who depend on the water from the Cauvery River for their livelihood. Crops are withering, and tempers are inflamed. Added to this monsoon failures have aggravated even the basic need of drinking water. Threats of violence have transformed into aggressive protests ending in deaths , property loss, Productivity loss & inconvenience to the people. Yet there is no solution. Since three decades, Karnataka is facing similar dispute over the sharing of the water of the Mahadayi or Mandovi river between the states of Maharashtra, Karnataka and Goa .The KalasaBanduri project aimed to divert 7.56 TMC of water from the Mahadayi to the Malaprabha river in Karnataka to address the drinking water needs in three parched north Karnataka districts of Belagavi, Dharwad and Gadag, was opposed by the BJP government lead by Manohar Parrikar that was in power in Goa at the time.

Can Concentrated Solar Power (CSP) Plant Technology Mitigate the Drinking Water crisis in Karnataka / Tamil Nadu ?

at a negotiated settlement. When all dialogue fails, disputes are referred to legal redressal forums like tribunals & finally to the Supreme court. Unfortunately over years, courts also have also failed to bring an amicable settlement & legal battle still continues. Drinking water is a basic requirement for any state ,which gets aggravated during monsoon failures. Looking at the above two major issues, Cauvery & Mahadayi, the crisis of drinking water which comes up often, can be technically solved to a major extent by setting up Renewable Energy Technology Plants with practically Zero Carbon emission using Concentrated Solar Power (CSP) Plants & Desalination techniques in the states facing the Sea coast. Using CSP plants, you will not only generate Electricity using Solar Energy, but also carry out Desalination of sea water to produce potable water. So how do we accomplish, what was once thought impossible, or at least improbable, by integrating Solar Power and desalination technology?. Use of Solar Energy : Solar Water Heaters We have already mastered the technology of Heating water using roof top Solar water heaters. This does not require explanation. Photovoltaic (Solar Electric) Photovoltaic (PV) devices generate electricity directly from sunlight via an electronic process that occurs naturally in certain types of material, called semiconductors. Electrons in these materials are

freed by solar energy and can be induced to travel through an electrical circuit, powering electrical devices or sending electricity to the grid. In this system Solar Energy is directly converted into usable Electricity. Concentrated Solar Power (CSP) Plants: Pipe carrying Heat transfer Fluid, getting heated from reflected Sun rays.

INCLINOMETER device continuously track the movement of the Sun & accordingly correct the mirror angle to ensure the reflected rays hit the pipe carrying the Heat Transfer Fluid. Sun energy from the parabolic shaped mirror surfacesâ&#x20AC;&#x2122; is directed to the thin pipes. (See Fig. 1) A heat transfer fluid (HTF) runs through the pipe which absorbs the heat energy directed to the pipes and it gets heated up to a temperature of 400 Deg.C. Upon pumping, the Heated fluid reaches ||www.electricalmirror.co.in||

expanded from 200 deg.C. down to 25 deg.C. If we want the exit steam for the purpose of Desalination, we need to cut short the expansion to 70 deg.C instead of 25 deg.C. This steam at 7o deg.C is then condensed in a separate heat exchanger where its heat is used to evaporate Sea water at a temperature just below 70 deg.C. By this we avoid formation of salts during evaporation of sea water & thus able to produce desalinated / potable water. Use of Concentrated Solar energy can result in the following.

Hot molten Salt Storage Tanks For Night Power Generation

At the high heat conditions, water is converted to steam form which rotates the turbines and thus electricity is produced. Here the system works like any conventional Thermal Power plant, except, instead of the Fossil Fuel, we are using sun energy for producing steam. 97% of sun light that falls on the mirrors is reflected to the HTF tube. For maximum utilization of sun’s heat, a devise, Inclinometer, is used to track the physical position of the sun. The troughs change their angular position and face the sun accordingly, like a sun flower. In order to have continuity of power generation during the sun set /Night periods, the heat transfer fluid also pass through heat insulated tanks containing molten (Brine Solution) salt which gets heated & the heat that gets stored in these tanks is later used during sunset period for generation of Electricity.

Reliance Power has also started construction of a 125 MW Power Plant using this technology at Dhursar (Rajasthan) which is going to be operational in the beginning of next year. Even this plant is designed exclusively for power generation & does not envisage Desalination. Using Salt water directly instead of pure water for steam production required for turbines would be a disaster. Once the temperature of water gets to 60 or 70 deg.C salt will start separating from the solution & coat the pipes. If that wasn’t enough of a problem, as evaporation continues, the water gets saturated with Sodium Chloride & massive amount of salt would get deposited around the evaporator pipes affecting the entire power generation. In practice, thermal desalination is co-located with CSP plants, but desalination is done indirectly. Typically a turbine in the power plant the steam is

Benefits of Concentrated Solar Power Plants: • Availability of affordable and clean electricity & would have a significant impact in cutting emissions of CO2. • Unlike Nuclear plants, no danger of radiation or damages to humanity & Property or problems of storing ‘Spent’ Fuel rods etc. The Accidents of Chernobyl & Fukushima Nuclear power plants can never be forgotten. In fact the city of Chernobyl has been fully evacuated after the accident & is totally deserted after stoppage of all the four Nuclear units. This deserted area can be now be used to install these Solar powered plants & generate as much power as all the earlier nuclear powered plants were producing. • The production of drinking water by the desalination of sea water using the waste heat from CSP plants.

Fig.3 shows the requirement of the desert area to feed the entire Europe as well as the entire Power requirement of the World using CSP technology. The map is a good illustration of the potential of solar power and how little space would be needed to power the entire planet. Some of the plants to be located on the border of the desert facing sea will also use desalination facility to provide drinking water to the people in the desert.

Now the mutual flux as developed out of it for each bunch (containing 2 Nos of GO and 2 Nos of RETURN) was becoming subtractive in nature ( ref fig 2.7-b) and not affecting the actual flow on the injection current. So the current injection from the kit became smooth and attained to the rated value of the CT.

Difficulty during current injection to BB scheme:- While attempting current injection from a primary kit to the 2 BUS system ( 2 No feeders had been taken in the circuit with its CTs, isolators and breakers as shown in figure 2.8 ) for stability of the BB scheme, it was not injecting current to the system. 54

the three sides & our requirement of Power can be very well met by this technology, generating clean Electricity without any Carbon emission. Why not Karnataka Govt, & Tamil Nadu Govt, take the assistance of the Central Govt. in developing CSP plants along our coastal Area and generate not only the much needed clean Electricity, but also handle the drinking water requirements of the people. Even after two to three decades have already passed & the Cauvery / Mahadayi river issues have still not found any solution, on the contrary, as the years prolong, with the population increase, the available sources of river water also depleting due to monsoon failures, the river water crisis among states will only aggravate affecting the drinking water requirements also. Hence using the above technology it would be possible to mitigate the water crisis & at the same time produce the much needed Electricity through renewable

technology without Emission.

Attempts taken:- The connection from the KIT was thoroughly checked with tightness of the connecting leads. The resistance of the current carrying path ( Total BUS system containing 2 NOs CTs, Isolators and Breakers) along with testing leads were also measured and found of value more than 5 Ohm. Then the isolator contacts were cleaned, adjusted

Analysis:- The current injection from the primary kit has certain value of burden to which the kit can inject current successfully to the system. During initial condition, the resistance of the circuit was approximately of 5 OHM, which becomes more for which the required current was not getting injected from the kit. However after tightening

with tightening of the bus jumpers till to obtain the value of resistance less than one ohm. After obtaining the required value of resistance, the current was injected from the kit and successfully it was driven to the required level.

and cleaning the surface of the isolator contacts, the required resistance was reduced, for which the required value of current could be injected from the kit.

The Real Life of Transformer can be Better then Today, How ?

ost of us are injected with an incorrect information that life of a good transformer should be 25 years and unfortunately, it is accepted by most users. Shockingly, no electricity board or utility keeps a record of transformers which have failed after 10 years of service. There are transformers which are in service for more than 45 years which have not been appreciated as deserved.

Why can not the life of a transformer be extended to 7080 years ?

Transformers ageing actually start with their dispatch from manufacturers end. It starts well before energizing the same. A close watch is necessary to get maximum life of a transformer, which enables a user to take timely remedial actions. No manufacturer can guarantee a product free of all imperfections, and no two units will experience identical handling and use, so the service life can be only estimated. Recently, we carried-out reconditioning of a 26 MVA transformer at NFL. The transformer was manufactured in 1971 and I am sure that this will give satisfactory service for 15 more years. It is already 45 years old transformer and may work till 56

the age of 60-65 years. This is not the only case. There are several transformers which are in service for more than 50 years.

What makes a transformer to live for a very long period ?

To understand above, we must first understand that what kills a transformer? If we forget accidental failures and discuss only about age-related failures, the main two killers are moisture and abnormal temperature rise. Moisture content of > 3% in a transformer (in liquid and solid insulation) by dry weight of insulation can put the transformer in high danger zone and can be responsible for pre-mature death of a transformer. And transformers manufactured with A class ( IS 2026) insulation with mineral oil filled can safely be operated at 88 degree C when the ambient temperature is 45 degree C, to get unity life from it, for which it was designed. Each 6 degree C extra rise of temperature reduces its life by half. Over heating is the result of poor design, poor cooling system and actually putting more loading on transformer than defined. Transformer ageing is related with the condition of the insulation system, which is typically based

on organic products, which degrade with time. Age of liquid insulation can be reversed but this is not applicable to solid insulation. However, the ageing rate can be reduced to a large extent. Here are few steps which GEW Trafotech has taken to extend the life of a transformer to >50 years: • Ensure that life of transformer parts used does not exceed their rated life and timely replacement is done. • Use of different class of insulation which is non-hygroscopic. Why is it necessary to manufacture transformers with A class hygroscopic insulation only and first allow them to gain moisture and then extracting it by using incorrect methods? • For A class insulation liquid filled transformers, a sealed breathing system (patented by author of this article) is provided along-with an oil purifier mounted on transformer which works without use of electric power. This keeps the transformer dry to an acceptable level. • The mineral oil conforming to IS 335 does not have good capacity to store large amount of moisture. After a limit, it stops storing moisture and this gets entry to solid insulation of transformer, causing fall in DP value of paper. We ||www.electricalmirror.co.in||

Event

INTERSOLAR INDIA 2016 Comes to a Successful Close 12,000 visitors, 800 conference attendees and 240 exhibitors: October 21 marked the end of the hugely successful eighth Intersolar India, India’s largest exhibition and conference for the solar industry, which was held at the Bombay Exhibition Centre in Mumbai. The number of visitors was 10% higher than at the previous year’s event, and the number of exhibitors increased by an impressive 20%. The positive development of the Indian solar market was noticeable at the exhibition. Businesses and investors made the most of the opportunity to network, and numerous agreements and collaborations were initiated. The organizers also reported positively on the conference, where around 800 attendees discussed India's solar industry with 122 speakers. Since Indian Prime Minister Narendra Modi declared energy a top priority, the Indian market has been showing great momentum. By 2022 the country aims to achieve an installed photovoltaic capacity of 100 gigawatts (GW). At the conference session titled India’s Emerging Domestic Market – A Reality Check, Priyadarshini Sanjay of Mercom Communications stated that the capacity is currently at 8.6 GW. According to the consultancy firm Bridge to India it is at 23 GW when projects currently under construction are included. So the country has ambitious goals, and the atmosphere in India is one of radical change. This year Intersolar India gave the industry a significant boost and offered the perfect opportunity to discuss upcoming steps, opportunities and challenges. Intersolar India was officially opened by Dr.

Robert Habeck, Minister of Energy, Agriculture, the Environment and Rural Areas for the German state of Schleswig-Holstein. He praised the development of India’s renewable energy industry and emphasized that exhibitions like Intersolar India help to achieve ambitious goals, as they act as an industry platform and bring together all of the key stakeholders. Smart renewable energy, which refers to the combination of energy generation, storage, grid integration and energy management, was a very popular topic at the exhibition and sparked animated debate at the exhibition forum in particular. At the session Smart Renewable Energy: Microgrids – Serving Unconnected Remote Village Communities to Grid Connected City Consumers, experts shared their experiences of bringing electricity to small villages through microgrids. The latest developments in the industry were presented at the session Smart Renewable Energy: Electrical Energy Storage (ees) – What are India’s Drivers for ees Solutions ? Shared Booth HUSUM Wind India This year also marked a first for Intersolar India – the debut of a cooperation with the internationally renowned exhibition HUSUM Wind, which proved to be a great success with the exhibition guests. The shared booth gave visitors the opportunity to learn

more about wind energy and its implementation in the Indian market. There was a lot of interest, as numerous Indian firms operate in both the solar and the wind power sector. Lively discussions at the Intersolar India Conference The accompanying conference took place in parallel on October 19 and 20. A central topic was private and industrial rooftop systems. In the session Commercial & Industrial Rooftop Systems – Field Experience in India, Dr. Nalin Shinghal, Chairman and Managing Director of Central Electronics Ltd., explained that rooftop systems will achieve grid parity in the near future. This is an important step, since although India plans to install 40 GW of solar capacity on private rooftop systems, its current capacity is just 800 megawatts. Sukesh Kumar Jain, Power Secretary for the Government of the National Capital Territory of Delhi, told the session titled Residential Rooftop Systems – System Design and Field Experience in India that the city will play a central, pioneering role. By 2020, he said, 1 GW of private rooftop systems should be installed there, with a further GW installed by 2025. There was also discussion around the challenges facing the expansion of private rooftop systems. Arvind Karandikar, Managing Director at Nexus Energytech Pvt. Ltd., mentioned that the financing of these systems must be structured more simply and that business models in this area need better support. ees India In 2016 ees (electrical energy storage) India again took place in parallel to Intersolar India. At the companies’ booths, numerous visitors learned more about the energy storage sector. This event complements the exhibition perfectly, because batteries are essential for India’s journey to a renewable future. Intersolar India 2017 takes place from December 5-7, 2017 at the Bombay Exhibition Centre in Mumbai. Further information is available at www.intersolar.in

Multi-function Testing for Transformers Comes to Power with the New TRAX by Megger By Peter FagerstrĂśm - Business Unit Manager instruments already owned, why spend extra on a multifunction tester that will duplicate at least some of the functionality of the existing instruments? The answer is investment for the future. Buy a multifunction tester and it will probably be unnecessary to replace the singlefunction instruments as they come to the end of their lives.

It is still common practice in substation testing to use separate instruments for each type of test. This situation, however, is about to change. There are, in fact, many compelling reasons to move away from separate instruments in favour of a multifunction test set, including :

1. Users of multifunction instruments always have all of the test facilities they need readily at hand; there is never a need to go back to the van or, worse, back to base to fetch another instrument for the next test. Plus, a single multifunction tester is much easier to transport than several individual instruments. 2. Multifunction test sets cost less than the individual instruments that would be needed to cover the same range of testing requirements. 66

NOVEMBER 2016 || ELECTRICAL MIR ROR

Four single-function test instruments = four displays, four user interface systems, four enclosures, etc = higher total cost than one multifunction instrument with one display, one user interface system, one enclosure, etc. 3. Multifunction test sets provide on-going savings by reducing testing time. There is only one instrument to unpack, power up and configure; the same cable set is used for a whole range of measurements, so the connections only need to be made once; and, when carrying out a range of tests, users of multifunction instruments move quickly and easily from app to app, rather than having to go from instrument to instrument. 4. Less operator training is required; users of separate instruments need to familiarise themselves with the quirks of each, whereas users of well designed multifunction testers enjoy a consistent user interface across all functions, which means that the learning process is simplified. This begs the question that if multifunction instruments have so much to offer, why are they not used more frequently for substation testing? The reasons are interesting : 1. Inertia. Separate instruments have always been used in the past and have delivered satisfactory results, so why change? The simple answer is that changing brings the benefits that have already been described. 2. Cost. If an additional single-function instrument is all thatâ&#x20AC;&#x2122;s needed to complement

3. Specification. Until recently, few, if any, adequately specified multifunction instruments were available. This is not particularly surprising, as designing and manufacturing a versatile, convenient, dependable and easy-to-use multifunction tester for use in substations presents many challenges. A multifunction test instrument design that can lead a migration from single-function instruments must: Be capable of generating high currents and voltages yet remain easy to transport. For users with interests that cover a wide geographical area, it is highly desirable for the instrument to weigh less than the international maximum shipping weight of 32 kg for check-in luggage on passenger flights. Alleviate the potential conflict between versatility and ease of use. Thereâ&#x20AC;&#x2122;s little point in producing a multifunction instrument that can perform a wide range of tests if many of the tests are difficult to access and set up. This only leads to user frustration and ultimately dissatisfaction with the product, however impressive its claimed abilities may be. Fortunately, recent advances in instrument design and technology have made it possible to produce multifunction testers for substation and other power applications that address both of these issues, making them truly attractive to users. An excellent example is a recently released integrated transformer and substation test system. ||www.electricalmirror.co.in||

Product Info

This compact unit, the main section of which weighs just 32 kg in its transport case, provides comprehensive facilities for testing power transformers, current transformers, potential transformers, circuit breakers, rotating machines and many other items of substation equipment. The base unit can generate AC current up to 800 A, DC current up to 100 A, AC voltage up to 2.2 kV and DC voltage up to 300 V. With optional accessories, the AC capabilities can readily be extended to 2,000 A and 12 kV. The voltages and currents generated by the instrument can be controlled and measured with a high degree of precision, allowing it to be used for an exceptionally wide range of applications that includes, for example, turns ratio, winding resistance and excitation current measurements in transformers; contact resistance,

impedance and tan delta/power factor testing; main and resistor contact timing in circuit breakers; and primary injection testing in LV, MV and HV equipment of almost any type. Other key features include exceptional interference suppression to secure accurate readings even in switchyards where high levels of electrical noise are present, a wide operating frequency range of 5 to 500 Hz (1 to 500 Hz for tan delta measurements), and individual temperature correction of tan delta measurements using patented technology. The challenge of delivering a simple user interface to complement this vast range of capabilities has been met by making use of the latest colour touch-screen technology and by designing the user interface so that it presents functions in the form of apps (“virtual instruments”). When the user has decided what to measure and has selected the app/instrument to work with from the start screen, the display shows

only those elements that are appropriate to the chosen function. For example, if the winding resistance instrument is selected, the screen simply shows the output current, the output voltage and the measured resistance. The user selects a test current and starts measuring. Users who prefer test guidance from the instrument simply enter the configuration and the unit provides connection diagrams and a table showing the sequence of measurements. Provision is also made for full manual testing with a generic instrument app that allows the user to freely select outputs, measurement inputs and the way in which the measured data should be processed. This remarkable new multifunction substation test set – the Megger TRAX – conveniently and cost effectively replaces a whole battery of conventional single-function instruments. Let the migration begin!

Product Info

Reliable Flow Measurement..... Positive Displacement Meters Offers More.....

Wherever Liquid, vaporous and gaseous media need to be reliably metered, controlled and regulated, that’s where our company’s products are used. Flow measurement plays a critical role in the petroleum industry for producers of both crude oil and natural gas and in the chemical petrochemical Industry. After crude oil is removed from the ground, it passes a number of custody transfer points before reaching a refinery. Oil is measured in the refinery, and refined products are measured as they leave the refinery. With a product so valuable, it is important to know how much is being transferred at many points along the way. Flow meters also play an important role in this market. These include turbine, positive displacement (PD), and differential pressure (DP). Traditional flow meters have been in the market for more than 70 years. Some of these meters, such as turbine, differential pressure and positive displacement. Trend towards newer technology has been in the works for more than 15 years. This newer flow sensor technology is not only experiencing the most promising growth rates, but taking considerable market share away from the older, more traditional flow sensors.

The Flow Transmitter Technology Positive displacement flow meters operate by capturing the fluid in small compartments whose size is exactly known. The meter counts how many times this capturing occurs. This value is then converted into a flow rate, sometimes by the use of a flow computer. The history of PD meters goes back to the early 1800s. Fluid flow initiates rotation of the almost frictionless gears and the measuring chambers that are constituted by the space between the gear teeth and the housing, define a known discrete volume of liquid that pass through the meters. The rotation of the gear wheels is such that exactly one tooth pitch defines that volume. This rotation is detected by a system of two non-contacting magnetic field coils that are offset by a quarter of a tooth pitch. This phase shift in gear rotation recognizes the flow direction as well as provides for doubling or quadrupling of impulses that lends the meter an excellent capability for resolution of the generated flow signals. Positive displacement flow meters are widely used in liquid hydrocarbon measurement for custody transfer and chemical process applications. They are used to measure the transfer of liquid hydrocarbons to and from trucks, rail cars, and airplanes. Oval Wheel Meter

WATER METER The operation of the water flow metering in a simple User friendly way to enable to operate easily. The Water flow meter is a impeller multi jet type flow meter with the measuring inserts are made up of engineering plastics. The water meter has a provision for fixing of external digital pulse sensors suitable for remote and digital pulse transmissions for monitoring through BMS systems and batching purposes with PLC and etc.. These flow meters used to measure the water consumption of apartment flats, IT park area, hospitals and malls. FEATURES: • For cold (50oc) and hot water (130oc) • Removable / interchangeable element • Sealed register water proof (IP 67) • Corrosion free powder coated body • EEC pattern approval • Unaffected by external magnetic fields • Pulsers coated body fitted without breaking the seal for remote flow totalisation and flow rate indication. 70
