Transmission Project Worth ` 50K crore Would be up for Bidding in FY'17 Transmission projects worth more than Rs 50,000 crore would be up for bidding during the current fiscal to increase power evacuation capacity in the country, Power Secretary P K Pujari said. Transmission projects worth Rs 50,000 crore would be auctioned. It could be even more than this during this fiscal," Pujari told reporters at a CII conference. He further said, "Last year (2015-16), we bid out transmission projects worth over Rs 1 lakh crore out of which Power GridCorp Ltd. got projects of Rs 56,000 crore and Rs 35,000 crore were awarded to private sector (on tariff based competitive bidding).” There has been healthy growth of the transmission sector during the 12th Plan (2012-17). After April 2012, India has added 90,000 circuit kilometres of transmission lines and 2.72 lakh MVA of transmission capacity. The auctioning of transmission projects assumes significance in view of govt.’s ambitious ||www.electricalmirror.co.in||

target of adding 175 GW of renewable power capacity by 2022. The share of renewables in energy mix, which is 6 % at present, will go up to 40 % by 2030. That will throw a huge challenge in the area ofpower system operation. It has technical implication for the grid. The Power System Development Fund scheme (PSDF) scheme was sanctioned for 2fiscalyears till March 31, 2017, to revive stranded as well as other domestic power plants running at sub optimal levels. The PSDF provides subsidy to power plants for buying imported gas, the govt. is weighing various options and is yet to take a call. "At present, we are looking at various options of policy for gas-based power plants of about 25,000 MW of capacities. Whether we will do (continue) PSDF or not, that is not very clear but we are looking

at options where we can provide assured gas supply to these plants without PSDF support at reasonable price," Pujari told reporters. He also said that for bidding conditions (requirement under PSDF), the Plant Load Factor (PLF) is 30% minimum. But this time it may be increased to 60%. That means the plants getting gas supplies to run their plants at 60% of their generation capacities would be eligible to participate in the scheme. On the GST impact on power sector, he said: "There is uncertainty about GST. We have set up a committee. Ministry of Finance has asked ministries to set up a group to look at the likely impact of GST on their sectors. We have told the group to get the feedback of all the players so that when actual formulation of GST takes place, we should be able to present our case."

Govt. Draws Contingency Plan for Coal Based Power Plants at Anpara, Rihand, Singrauli & Vindhyachal

There has been excessive rainfall in the Northern Coal Field (NCL) area during last few days. This unforeseen natural calamity has damaged roads, railway tracks and there is water logging in the open cast NCL mines. This has affected coal supply to Anpara, Singrauli, Rihand and Vindhyachal Thermal Power Stations. Contingency plan has already been implemented to ensure that the power supply due to this is not affected. If required, States can get the supply from alternate sources and power exchanges. The Sub Group Monitoring Committee reviewed the coal supply situation which was affected due to excessive rains and has issued a contingency plan to overcome the hurdles in coal supply to the Thermal Power Plants receiving coal from Northern Coalfields Limited (NCL). It has directed to the concerned agencies to put 6 numbers of BOBR rakes in circuit for coal supply to Anpara and Singrauli Thermal Power Station(TPS) till the MGR supplies to these plants are resumed. In addition to it, 2 Box ‘N’ railway rakes per day each from BCCL, CCL and ECL subsidiaries of CIL are

being sent to the Rihand and Vindhayachal units of NTPC as the coal for these units is diverted to the Anpara and Singrauli TPS. The imported coal stock lying at the port is also being moved to the Vindhayachal NTPC units. These pithead plants are designed to receive coal through MGR and therefore were facing difficulty in unloading coal through railway rakes. The coal supply is expected

An analysis by Greenpeace India finds that the country is heading towards an excess of coal power plants, more than needed to match the power demand projected for 2022, and will result in about ` 3,00,000 Crore of wasted investment into coal power plants. The analysis takes into account the growth rate of power demand, the capacity of coal power plants under construction and that are being proposed, India’s commitment to add 175 GW of renewable energy capacity by 2022 along with the upcoming capacity additions from other sources. The PLF which measures the capacity utilization of power plants has reached a historic low at an average of 62 percent in 2015. Despite this, 65 GW of new plants are still being built and over 170 GW are being proposed. Assuming the 65 GW of under construction coal comes online by 2022, 95% of these will be lying idle. The 61.7 GW of idle plants represents a stranded capital of approximately 3,20,000 Crore rupees (49 billion USD).

Distributed Energy Production - New Focus of Power Sector : Goyal

BHEL Commissions Another 660 MW Supercritical Thermal Unit in UP

Shri Piyush Goyal, Union Minister of State (IC) for Power, Coal, New & Renewable Energy and Mines said that it is very unfortunate that India continue to import coal from other countries inspite of the fact that we are a coal surplus nation today. While addressing a media event, Shri Goyal said, “this is because our power plants have been designed not to function on indigenous coal”. Speaking on the occasion, Shri Piyush Goyal informed that Coal India has set a target to replace about 15 million tones of imported coal with indigenous coal in the next six months. The Minister urged everyone to come up with new ideas for finding a sustainable solution for this challenge. Talking about power decentralization initiatives, the Minister said that apart from shifting to renewable energy, we are focusing upon distributed energy production, where consumers themselves can start generating power. In fact, the rooftop solar power programme will be expanded to 300 MW today to the 40000 MW in the next six years. It will not only provide energy security but will also give support to the thousands of people living in areas inaccessible to grid based power supply, he added. Discussing the problem of climate change, Shri Goyal reiterated that India believes that fighting climate change is a global responsibility. But having said that, it is imperative that the world strives towards sustainable lifestyle. wasteful usage of energy is a big concern today. He said, “we are very concerned to see how the developed world is going to respond to this challenge in terms of demand side management of their consumption.”

Bharat Heavy Electricals Limited (BHEL) has commissioned yet another 660 MW coal based supercritical thermal power plant in Uttar Pradesh. Notably, in the past 15 months, BHEL has added 4,300 MW of power generation capacity in the state of Uttar Pradesh. The commissioning of the unit will result in significant improvement of electricity availability in the state of Uttar Pradesh. The unit has been commissioned at the 3x660 MW Prayagraj Super Thermal Power Project, located in Bara tehsil in Allahabad district of Uttar Pradesh. The project is owned by Prayagraj Power Generation Company Limited (PPGCL), a subsidiary company of Jaiprakash Power Ventures Limited. This is the second unit of the project to be commissioned. The first unit was commissioned earlier by BHEL in December, 2015 and the third unit of the project is also in an advanced stage of construction. BHEL’s scope in the project consisted of design, engineering, manufacture, supply, erection and commissioning of the Boiler and Turbine-Generator (BTG) package.

ABB Unveils Innovative Traction Transformer Reducing Energy Losses by up to 50 percent

ABB unveiled its next-generation traction transformer designed to reduce the weight of on-board components and ensure more energyefficient rail networks, two of the rail industry’s priority objectives. Named Effilight®, the product was unveiled as a ‘world premiere’ at InnoTrans, the leading global rail industry symposium, being held in Berlin, Germany, from Sept 20 to 23, 2016. Effilight can potentially reduce the total weight of a train’s traction component by up to 20 percent, equivalent to the weight of around 20 passengers. This weight optimization can help train carriages attain the maximum load per wheel set and reduce wear. Traction transformers feed power at safe voltages to essential train functions like traction, lighting, heating and ventilation, passenger information, brakes, signaling and communication. They are a critical element in the traction chain, affecting train

performance and operator services. Traditionally made of iron and copper, these transformers are among the heavier components on a train. They use oil for insulation and cooling, for its excellent electrical insulating properties and high reliability, but this also contributes to a significant proportion of the transformer’s total weight. ABB’s Effilight transformer uses a unique and patented high-technology cell design that reduces

Tulsi Tanti Flags Huge Growth of Renewable in Australia Tulsi Tanti, the founder, chairman and managing director of Suzlon Group, one of the leading renewable energy solutions providers in the world, has flagged the huge potential of wind power in Australia in a keynote address on “Climate Change, Clean Energy and Australia India trade” at the Annual Australia India address 2016 organized by the Australia India Business Council (AIBC) in Melbourne. Mr Tanti said there would be a US$5.86 trillion investment in renewable energy globally between 2014 and 2035 with wind expected to be the single largest source of investment representing 21 per cent of the total. “Australia is ideally situated to benefit from this investment with the demand for electricity in this country expected to increase by two per cent each year over the next two decades,” he said. Speaking at the event held at the Melbourne Cricket Ground, Mr Tanti said renewable energy had made the transition from alternate to mainstream on the global stage and the opportunities for Australia were enormous. “Wind and solar energy are growing at a rapid rate due to their cost competitiveness and the fact that they lower the carbon footprint,” he said. “There are also the advantages of eliminating the price uncertainty associated with fossil fuels and the modular, scalable and low gestation period of renewable energy infrastructure.” 20

A champion for affordable and sustainable energy, Mr Tanti has been named a 'Hero of the Environment' by TIME magazine for his contribution to raising awareness and initiating action on global climate change. He said Suzlon Group was committed to helping Australia make the transition to a low carbon economy and fulfilling its COP21 (Paris Agreement on climate change) commitment. With over AUD$2 billion Indo-Australia trade contributed by Suzlon so far, Mr Tanti also reiterated the company’s commitment to further strengthening IndiaAustralia bilateral trade relations, specifically in capital goods and the renewable energy sector. The Australian Government has set a renewable energy target (RET) of 33,000 GWh by 2020 meaning about 23.5 per cent of the nation’s electricity generation will be from renewable sources by 2020. All state governments have also announced renewable energy targets.

Cover Story 1 Introduction Since proposed by F. C. Schweppe in 1970, state estimation (SE) has become one of the key functions in power system monitoring and control. It supports the state monitoring and many important functions like optimal power flow, voltage control and so on in the energy management system (EMS). At present, SE has been extensively deployed in transmission systems, while the implementing in distribution systems just gets its start. As a growing number of distributed renewable energy such as wind and solar integrated into distribution systems, stochastic changing characteristics of these sources may cause sudden changes in the system and affect its stable operation; Application of next-generation digital devices such as phasor measurement unit (PMU) and intelligence electronic device (IED) enÂŹriches the monitoring tools of distribution systems on one hand, while taking full advantage of the new type data could be a problem on the other hand. Future distribution systems will be active distribution systems with high penetration of distributed energy and new type monitoring devices. Certain scholars begin to take the transformation into consideration and some clues can be found in their works of recent years, but more in-depth research need to be done. Other than transmission system, distribution system has its own characteristics: radial topology; three phase unbalanced system; high resistance to reactance ratio; very limited number of real-time measurements. All of these features make distribution system state estimation more challenging and transmission system SE techniques cannot be applied directly to DSSE. In order to meet the new challenges and provide reference for future study, this paper reviews the research status of distribution system state estimation on algorithm structure design, insufficiency of real time measurements and meter placement. The difficulties and challenges of the future active distribution system with high penetration of distributed energy and new type monitoring devices are also presented at the end of the paper. 2 Algorithm structure design of DSSE In the early work of DSSE, in common one phase model was replaced by the unbalanced three phase model and pseudo measurements were proposed when come to the problem of real time measurements insufficiency. But the whole algorithm structure of state estimation was still the conditional centralized weighted least squares method Because of the newly emerged features such as data tsunami in the active distribution

system control center, the centralized way will come up with much pressure of communication and computation. Several researchers throw some light on the algorithm structure design of the DSSE in the last years. The status of the distribution system in the chain of the whole power system is rising gradually with the rapid development of smart grid. In the work of a multilevel state estimation paradigm for smart grid is proposed (see Fig. 1). This paradigm resolves the whole system into tree levels namely local SE, transmission level SE and regional multi-TSO SE from the bottom up and the local SE can be subdivided into feeders SE and substations SE. Each level only handles the outcome of information processing from the lower level in the paradigm whose idea indicates the implementation path of SE in the power system and in line with the trend of the development of future power networks. The factorized WLS method is adopted which resolves nonlinear problems into a couple of easier subproblems and suites the hierarchical and distributed SE. Although the method in meets the need of practical operation, the arithmetic result is still suboptimal solution. Benchmarked against the SE of centralized WLS, a closed form expression is developed that predicts the expected error in the factored estimate for a given system operating point. For the problem of distribution system substation SE, literature develops a agent-based method in which

the role of the primary substation is to periodically initialize a token and pass it forward to the closest neighboring substation. Through the passing of the

Fig. 1: A multilevel state estimation paradigm for smart grid. (LSE: local SE; TSE: transmissionlevel SE; RSE: regional multi-TSO SE.) token, tasks such as topology analysis, observation analysis and bad data detection are completed and the agent in the secondary substations does the SE utilizing the information of local control center, statistical calculation and neighbors. But the main concentration of the agent-based method is on the design of concept, more detail techniques need to be further researched. On the basis of, literature proposes a two-level SE technique for the substation SE with the idea of multi-area SE. In the first stage the overall SE is decomposed into f+sWLS sub-problems (f and s being the total number of feeders and substations, respectively), which are then solved in a decoupled manner. The second stage, involving a linear WLS problem, ||www.electricalmirror.co.in||

consists of coordinating the solution provided by each subsystem. A fully distributed DSSE is developed utilizing the Super Calibrator (SC) in. In the scheme voltages in the substation are captured by the adequate measurements like SCADA, IED and PMU, while those in the neighbors modeled as pseudo measurements. The advantages of this scheme are noticeable namely high precision, stable and without debugging. But the need of installing PMU in every substation is difficult to achieve in the short term. From the above it can be observed that, for future active distribution systems of complex structure and massive data, the hierarchical and distributed way is avenue for future research of DSSE. Multi agent and multi area SE method are worthy of reference with regard to algorithm of distributed SE. In the sceneries of high penetration of DG, the distributed way can alleviate the pressure of communication and computation while SE algorithm with high precision is expecting more indepth study. In addition, the affection of network and the new type intelligent equipments must be the factors taken into consideration. 3 Insufficiency of measurements of DSSE Other than transmission systems, distribution systems have much more buses in number, more complicated structure and the real time measurements are woefully inadequate. The insufficiency of measurements leads to the unobservability of the system that makes it a ||www.electricalmirror.co.in||

serious problem of DSSE. Scholars do a lot of research to insure the observability of the system and redundancy of measureÂŹments. Most of the work are molding pseudo measurements and can be clarified as: 1) Given distribution coefficient and factor of power. On the basis of the probability state estimation, papermakes full use of information such as the typical profiles of loads, power measurement probability and bill of electricity, putting forward a real-time load modeling technology. This paper describes the load behavior as some relevant variables function of relevant variables typically like season, time and temperature, and the essence is to obtain certain types of daily load profiles. Analogous method is a relatively common practice in the early research. 2) Fuzzy mathematics. Literature using the fuzzy state estimation technology in the load configuration makes use of triangular fuzzy number to model the unknown or uncertain measurement; Literature considering the uncertainty of estimated input, comprehensive fuzzy state estimation method is put forward. The authors use historical data, the fuzzy influence of them and the real-time measureÂŹments to initialize the fuzzy load current, meanwhile utilize correction by fuzzy estimation to reduce the uncertainty of the load current. 3) Auto-regressive Moving Average (ARMA). The multi-variable ARMA model of load is established in, and the order of the model is set by adaptive multi-mode segment filter. Although only the daily total electricity is studied, the method still suits the research of the daily load profile modeling. 4) Gaussian mixture model (GMM). In order to use the WLS algorithm, load values tend to be considered as pseudo measurement of normal distribution with certain expectation and variance, but this assumption does not reflect the real situation. For the load of distribution system is highly fragmented and of various types, literature put forward the gaussian mixture model to represent the probability density function of the loads. Its advantage is that GMM model suitable for different kinds of loads, and they can be represented as several convex combination of normal distribution which applicable to the WLS. 5) Artificial neural network (ANN). Paper models the injected power of DSSE as pseudo measurements using artificial neural network

method. ANN training is achieved through the load profiles and a small amount of power measurements, then the difference between ANN and the load profiles being modeling by the GMM. By retraining the ANN, the problems of the load growth of distribution system and topology changes could be easily solved, so the robustness of this method is distinct. But ANN retraining and the GMM modeling of errors need to spend some time. Except for the factor graph method to depict the distribution system, the majority of above methods are based on historical data to predict the unknown load profiles, thus limiting the accuracy of calculation. As population of the advanced measuring system (AMI) in the power system, measurement data sources of distribution system state estimation become more rich, providing more possibilities of the supplement for the measurements as well. Literature models the pseudo measurements through joint usage of automatic meter readings and the historical load data; Literature compares the SE outcome between introducing historical load data as the pseudo measurements and the same to the AMI data, then find the errors of the latter are smaller; Literature treating AMI nodes as the boundary nodes, proposes a hierarchial distribution system state estimation method specially for radial topology of the network. Recent years, some interesting scenarios are studied by a few scholars. All measurements data are from smart meters in and the issue of nonsynchronization is investigated. With a bit of resemblance, the work of casts DSSE with only a few micro-PMUs using compressing sensing technic and 11 regularization. Besides, In addition to the measurements data, the electric power enterprise's operational data and the rich external data of distribution system may result into the problem of the processing of big data' 1. Big data analysis technology will offers a new approach for load modeling of pseudo measurements. 4 Measurement configurations The measurement configuration of power system is to deÂŹtermine the distribution locations, types and quantity of the configuration in the system. The quality of the measurement configuration not only directly depends on the observability of the system, but also has an impact on the result of the power system state estimation. Nowadays, there has been a lot of research on the measurement configuration of the power transmission network, which can be classified into two categories according to the configuration goals' 1: the first type is to improve the observability of the system, and the second type is to make the state estimation error as small as

possible. However, there is a big difference between the power distribution system and the power transÂŹmission network on the measurement redundancy and the topology, leading to the difference on the measurement configuration. Since the algebraic observability of the distribution system can be ensured by pseudo measurements, it is more concerned about the promotion of estimation quality and the reduction of configuration cost with respect to the measurement configuration. Moreover, in distribution system real-time measurements and pseudo measurements complement each other and jointly meet the requirements of state estimation of measurement redundancy. First identifies the required data in the real-time monitoring of the distribution system, and then proposes a rules-based Feeder measurement configuration method according to various importance of the monitoring variables in distribution system, which is a trade-off between the accuracy and the calculation load. Literature takes into account the issue of voltage measurements placement of the distribution system with DGs, and proposes a heuristic method to reduce the estimated standard derivation of voltage amplitude on buses without measurement and to ensure the output of DG will not violate the limits. Paper considers the measurement configuration of distribution system as a multi-step decision making problem and emÂŹploy the dynamic programming algorithm to accomplish the distribution of measurements. 32

measurement. This reference also considers to minimize the measurement configuration cost while meet the accuracy requirement under the topology change. In addition, the application of smart meter data and PMU data is taken into account in the process of state estimation. Different from the above work which cast meter placement only for single configuration distribution systems, develops a robust approach for all possible configurations of the system, in which submodular saturation algorithm is proposed and outperforms the greedy algorithm and the genetic algorithm in most cases. As observed in above reviews, the methods used to solve the problem of measurement configuration, such as dynamic programming, sequence optimization, genetic algorithm, and so on, generally adopt a stepwise strategy to gain the solution according to specific indicators. Subject to the problem of cost and scale, measurement configuration of distribution system does not regard the estimation accuracy as the only standard. Additionally, the history of applying smart metering system and PMU in distribution system is not long and the relevant measurement configuration problem is worthy to be explored further. Meanwhile, the cost is saved by fusing multiple measurements of a same bus and Monte Carlo approach is utilized to address the uncertainty of measurement equipment and line parameters. Reference adopts a Monte Carlo simulation based probabilistic method to reduce the relative error for all bus voltage and phase angle estimation. The meter placement is completed by continually improving the binary probability index relevant to the error. Particularly, the problem of meter placement is transÂŹformed into a probability border reduction problem by using the Chebyshev inequality in both sides and then solved by using the error ellipse. As an improvement on reference, reference accurately calculates the probability of error limit violation and transforms the problem into a stochastic problem solved by utilizing sequence optimization (00), as a result, obtains the same threshold boundary as reference withless measurement. Literature investigates the problem of PMU distribution in distribution system by regarding the phase angle of node voltage as state variable, and proposes a hybrid algorithm which uses Nelder-Mead Simplex Method for local search and ant colony algorithm for global search. Paper for the first time studies the distribution issues of PMUs, smart meters and other mixed measurement equipments, and adopt genetic algorithm to achieve the optimal balancing of measurement substation, pseudo-measurement, phase angle measurement and intelligent measurement equipment

5 Difficulties And Challenges of Active DSSE On the issue of SE, the active distribution system with high penetration of distributed energy and new type monitoring devices has its own characteristics different from the traditional distribution system and the transmission system, while they have some in common. It would be of great significance to take the features of the active distribution system into consideration, and draw lessons from the research results on similar problems of the Miters at the same time. In addition, the application of the power electronic equipments such as FACTS, the growth of the electric power enterprise data and the introduction of the network factors will brings new difficulties and challenges to the distribution system state estimation. 1) Diversity of the monitoring objects & complexity of dynamic characteristics : Different from the traditional distribution system, there are power generation units, such as renewable energy and power generation and consumption units, such as battery energy storage system and plug-in hybrids in the active distribution system in addition to the traditional power loads. SE needs to clarify the relationship between these objects and important degree, and look for the right pseudo measurement modeling technologies. Besides, the net-source-load multi modal of micro-grids, random access of plug-in hybrids and application of DFACTS ||www.electricalmirror.co.in||

increasing the dynamic complexity of the distribution network, puts forward a new challenge to estimate the real-time state of distribution network. 2) Diversity and magnanimity of data: In addition to the traditional SCADA data, the application of more and more intelligent devices and PMUs will be the trend of the development of active distribution system. The types and accuracy of measurements are usually different, so it is urgent to consider the configuration problem of the distribution network mixed measurements. PMU measurements sampling frequency is much higher than SCADA measurements, greatly increasing the need to deal with the amount of data. From the perspective of relieving the communication and computation burden, event-triggered method can be considered. At the same time, the electric power enterprise operational data and external data contain abundant information and it is need to study big data mining technology on cloud computing platforms of the power system. 3) Network factors : With the development of the active distribution system and the improvement of power distribution automation, the traditional centralized system based on RTU and a large number of control protection device, will gradually be replaced by the networked control systems of multi-functional IEDs. After the introduction of network factors in measuring system, the resulting network induced delays and packet losses will cause the sanity of the measurement information. How to do SE in the case of incomplete information and ensuring the robustness of SE under the networked environment will be the future problems. 6 Conclusion There have been decades since the power system

||www.electricalmirror.co.in||

state estimation has been proposed for the first time and it enables EMS to perform various important control and planning tasks. Motivated by the deploy of advanced measurements and penetration of distributed generation, DSSE would play an increasing role in the future grid. These paper overviews DSSE from the respects of algorithm structure design, inÂŹsufficiency of real time measurements and measurement configuration, and some recent work of scholars involve new revolution of distribution system. According to the features that have already or will emerge in the future of active distribution system, the author put forward new difficulties and challenges of active DSSE at the end of the paper.

Market opportunity India presents a reliable, fast growing, well-diversified, and profitable market opportunity for renewable energy. The imperative to add substantial new generation capacity to meet social and economic needs is helping India reshape its energy mix towards renewables quicker than other regions. Power utilities and retail consumers alike are contracting with large-scale renewable energy suppliers to meet their basic energy needs. India’s per capita energy consumption is very low, in fact, it is about onethird of the world’s average and below other comparable developing countries. The growth picked up in recent years rising from 612 kWh to 1,010 kWh over last decade 2005- 2015, a growth of 5.1% pa. Rural electrification and provision of 24x7 power supply is a key priority for the government. Based on available statistics 19,706 villages lack access in 2015, and a large proportion 33% of households do not own an electricity connection (2010 Census). In most states rural power supply is intermittent and of poor quality. New generation capacity must be built, and given the affordability and concerns of marginal consumers, renewables with minimal cost inflation suit it best. Urban centres, too, have grown rapidly and India, which is relatively less urbanised with only 31% of population in cities, is moving in the direction of other developing nations such as Brazil (87%) and China (50% urban population). Urban areas are

significantly more energy intensive and constitute a key driver of demand growth. The govt.’s drive to build 175 GW of renewable energy by 2022 will help achieve energy security and reform energy mix. The policy proposes to use RPO and RGO targets to develop this, and regulators are seen to take steps to improve enforcement. The gotv. has set in place a robust procurement model in the form of auctions and standard bidding documents vis. RFQ, RFP, PPA to facilitate a quick, harmonised, and transparent bidding process for solar power development. Solar energy potential estimated by the National Institute of Solar Energy is about 749 GW. This is spread across a wider number of states, viz. Rajasthan (142 GW), Jammu and Kashmir (111 GW), Maharashtra (64 GW), Madhya Pradesh (61 GW), Andhra Pradesh (38 GW) and Gujarat (35 GW).

capacity has grown to 23 GW last year. Also, total commissioned plus pipeline PV capacity, has grown to 23 GW, +70% over last yearand split nearly 40:60 between central govt. and state govt. policy projects. • Despite growing market, project development space is getting more concentrated wherein top 15 developers have gained nearly 50 per cent market share. Most players have 2-4x more capacity under development than their commissioned capacity and their ability to scale up will be critically tested in the upcoming year.

PV Business grew to 2-4x in 2015 According to a report published by BRIDGE TO INDIA,shows that India’s total installed solar capacity has grown by over 80% in the year ending June 2016 to reach 8.1 GW. Out of the 3.6 GW capacity added in this period, 75% has come from four southern states. Tamil Nadu now ranks number 1 for commissioned capacity. An additional 14,842 MW of projects are under development where auctions have already been completed. Almost 56% of this pipeline is concentrated in the 3 southern states of Karnataka, Andhra Pradesh and Telangana. Total commissioned plus pipeline PV

Canadian Solar, Trina and First Solar take the first three spots. 7 out of top 10 module suppliers in India are now from China as against just 4 out of top 10 in the previous year. Big change is a significant pick up in market share by new Chinese suppliers including JA Solar, GCL Poly, BYD, Talesun and Risen. These companies had a very marginal presence in the market previously but now have a combined market share of 22 per cent. ABB continues to dominate the PV inverter market with a commanding 35 per cent market share. Japanese players, notably TMEIC and Hitachi, have also gained a significant market share. It is worth noting that all the THREE companies are assembling their products within India. Chinese inverter suppliers such as TBEA, Sungrow and Huawei are also in the top TEN and becoming more aggressive in the market, says the report. Rooftop PV gathering speed Rooftop solar photovoltaic market in India is expected to add new capacity of 700 MW in 2016, 15 per centof total solar capacity addition this year, crossing 1 GW cumulative capacity by September and growing at a sizzling 300 per cent over last year. Significant rooftop PV capacity is expected to be added in the commercial and industrial segment as commissioning before the end of this month will allow investors to claim 80 per cent accelerated depreciation (AD). The MoF has reduced depreciation rate under the AD policy to 40 per cent from April 2017 but more importantly, it is not yet clear if the AD

benefit will be available for solar PV projects after this date. Critics notes that rooftop solar in India has maintained a 10–12 per cent share of the total solar capacity addition, which is much lower than other peer markets. Private sector, primarily commercial and industrial customers, are leading the demand growth but govt. sector is also looking very promising. India’s govt. wants to improve the rooftop PV share to 40%. MNRE and various state renewable agencies are finally beginning to address key market challenges helping to unlock the market potential. Historically, rooftop solar has maintained a 10-12% share of overall solar capacity addition in India. This is much lower than other key markets such as Australia (97%), Germany (73%), U.S. (46%), China (18%). The Indian govt. wants to improve this share to 40% or 40 GW by 2022. Solar Energy Corporation of India Limited announces a scheme for allocating 1,000 MW of rooftop solar on govt. buildings. Several govt. dept.’s have carried out an assessment & recently provided commitments to install 1.5GW of rooftop solar capacity. It is believed that the high growth phase of India’s rooftop solar market has only just begun i.e. this market has got a great potential and it is very encouraging to see the govt. addressing some of the key challenges. But !....the next hurdles ? While some see residential rooftop solar as an economically attractive no-brainer, others are more skeptical. Manufacturing challenges can be solved by more govt. funding, others argue.

The National Solar Mission earmarking 40 GW of its 100 GW 2022 installation target for rooftop solar, is a sector that needs more vocal, and optimistic, support. Rooftop solar in India is - a no-brainer, and presented a series of compelling cost analyses. With the Indian rooftop market projected to reach 1 GW by the end of the year, there is momentum building. And that momentum, can generate good returns for private adopters of solar. The average cost of a residential rooftop system is INR 5.74/kWh, while O&M is 3 per cent of the required INR 7,00,000 upfront investment. That is a pricey assumption for an average Indian household, but the returns make attractive reading. With the govt.’s 30% capital subsidy scheme, one can calculate that this discounted payback is just 5.2 years, with an IRR of 17 per cent and a total annual electricity bill saving of INR 134,000, and yes – “Rooftop solar in India is a no-brainer”. While those numbers may make sense for a handful of middle-class Indians, the majority either lack the appropriate funds, rooftop (80% of housing stock in India has flat rooftops because they do not have to deal with snowload) or space (many rooftops are partially shaded) to make investment in residential PV currently worthwhile. An official from SECI who attended Renewable Energy India (REI) expo held at Noida early this month said – “The govt. could have perhaps already done

three times what we have done so far for rooftop solar, but stressed that there have been many conflicting stakeholder interests. However, we have created a platform to escalate rooftop solar quickly over the next few months. The 40 GW is a target for the next 5 years, and to meet those requirements then the MNRE and sister organizations will place a huge thrust on solar installs. SECI itself has bought a 500 MW tender specifically for rooftop solar, and has earmarked 100 MW of that specifically for residential. The 500 MW have been finalized and the winning bids will be announced soon. They are mostly SME clients, but also public sector buildings that are eligible for subsidy. The reason the C&I rooftop sector has no subsidy support is because the govt. feels that the sector can add capacity independently, and then economies of scale will follow”. Tata’s head of business development group Kaushik Sanyal added– “Financing for rooftop solar PV systems is yet another currently scarce, and comes only from the banking sector via a typical home loan. Financing for the domestic sector needs to be addressed. There needs to be more awareness about long-term payback. Consumers will only look at the upfront cost, and then only the projected reduction in their bills. We need systematic awareness campaigning from govt., bankers, developers, everybody in the industry needs to do their bit to develop a more collaborative approach for residential growth”. State-by-state, some areas offer net or

gross metering, while in other regions there are concerns over grid-connection. It is also important for Discoms to map a network for this expected growth. Existing grids need expanding, but who pays? Regulators need to enter the picture and plan and pay for this anticipated growth in solar. If we build it, will they come ? India’s solar manufacturing landscape will be key to sustaining future growth, believe many observers. The country cannot be reliant on low-cost, imported Chinese solar components for ever, but at the moment the incentive to invest in domestic manufacturing capacity is suppressed by China’s infiltration of the market. However, machines have begun to whirr, and plans and confidence are building for more growth. Anyhow they are seeing more trust on module manufacturing in India. Economies of scale have to be there to be competitive with the Chinese. We also need to see technology as a consideration, along with scale. Scale alone cannot sustain the industry because it’s hard to compete with China. But if we have technology differentiation, and presence across the entire value chain from ingot to module, having that control means we are less dependent on the vagaries of the market. The market will be shaken up by deep-pocket players, as govt. has to take a step back and allow manufacturing in India to stand on its own two feet i.e. where adoption of technology and scale go hand in hand the govt. can only act as facilitator, make a clear policy, and time bound the subsidy payments. Delays do not work. Anyhow, the govt. has expanded the business

opportunity, now it is up to companies to take the lead. On the other hand only around 40% of India’s solar module manufacturing capacity is being utilized, and the situation is even worse for cell suppliers also developing polysilicon production facilities, had been tentative. Indian manufacturing is in a bad state. We need an urgent funding mechanism from govt. because banks are not going to fund these companies. Govt. backing, however, will boost skills and jobs. Lets believe that in the next year or two the smarter producers will look to integrate upstream. We don’t necessarily have to do the whole supply chain, but at least be integrated in order to control not only costs but also quality. It is important to have stable power and a low price. Low price labor here already, so we can see a very competitive potential here. These components make a winning combination. Solargize India is one company planning such vertical integration through its proposed 3 GW polysilicon production plant in Andhra Pradesh, to augment the firm’s 500 MW cell & 500 MW module production facility being built in Bangalore. The company expects to be producing polysilicon within 24 months. Post WTO decision…? The expected decision last Friday by the World Trade Organization (WTO) to reject India’s appeal against a U.S. complaint that its Domestic Content R e q u i r e m e n t s (DCR) for solar cells and modules was against regulations could well prompt the Indian govt. to develop more creative ways to

Made-in-India policy for panel manufacturing. Currently, cheap Chinese modules more than meet demand in India, with Bloomberg New Energy Finance data showing that in the first half of this year the country imported close to 3 GW of solar cells and modules from China. India’s path towards self-sufficiency could be aided by manufacturing power-storage solutions, particularly once prices fall closer to INR 1/kWh. It will take 3 more years when storage will reach the affordability that India needs. Also the govt. policies encouraging local production could help propel India’s storage market to the top table globally. support its manufacturing base. The initial impact of the ruling is likely to be minimal, and only the few manufacturers in India overly dependent on the DCR market are likely to be unduly affected. During the trade dispute, U.S. solar PV imports into India fell by more than 90% since the introduction of the DCR. However, the DCR played a very minor role in this contraction. Rather, India has been flooded by the world’s cheapest solar modules from China, retailing at or below an average price of Rs. 26/ watt. This is India’s larger concern, with domestic manufacturers – who generally produce panels at prices some 10-20% higher for DCR projects – struggling to compete. With the WTO ruling that the DCR contravenes global trade rules, India must now explore other, more creative and proactive ways, to protect and subsidize its manufacturing sector. The DCR only ever benefited a handful of developers anyway, because DCR projects are a small part of the solar capacity auctioned. Now, at least, manufacturers can have more clarity and adjust their strategy accordingly in order to offer competitive bids. The current DCR pipeline to be auctioned during the National Solar Mission’s Phase II batch 2, Batch 3, Batch 4, NTPC projects and SECI/Coal India Limited projects is 925 MW, which is less than the 1,167 MW of DCR projects awarded in previous rounds last year. The next step for MNRE is to develop feasible ways to nurture more local and competitive manufacturing without contravening WTO rules. Japan’s SoftBank Group Corp. has told Bloomberg that it is mulling a manufacturing joint venture in India to produce solar panels under a new partnership. The firm last year created a JV with Bharti Enterprises and Foxconn Technology Group to generate 20 GW of solar power. To build largescale manufacturing efficiency matching Chinese economies of scale will require govt. support. Indian support policies are in an evolution stage. It can be suggested that SoftBank’s SB Energy could move on a JV in India once the government puts in place a ||www.electricalmirror.co.in||

Case Study of The Month

Various Case Studies on Operation and Control Schemes for Grid Sub-Station Contd. ...

Er P. K. Pattanaik, is presently working with OPTCL as Asst. General Manager (Elect) in E & MR Division, BhubaneswarOdisha and associated with the Protection and Control schemes of Electrical systems. He is having 24 years of technical experience in Designing, Testing and Commissioning of Protection Control and operational Schemes, project Implementation, co-ordination, operations & maintenance of Electrical Equipments at various LT/ HT/ EHT level Grid Sub- Stations. He has also published around 70 technical papers in different national/international seminars/journals. ele.pkpattanaik@optcl.co.in

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. Operation of Power transformer with lower IR value : One of the 40 MVA transformer, Y-y connected 132/33 KV was in operation and taken shut down for condition monitoring. The results were found on IR measurement for HT-Body being 1 Mohm with abnormal value of the tan delta value also. Investigation and Analysis : The test results were reviewed and found with normal value for other terminals (HT-LV, LV-body). But it was observed with approximate equal value for HT-LV, LV-body. So from this observation it was confirmed that the HT neutral path either have been connected to the body or maintained with very less clearance to body. So the oil was drained for physical verification 42

of the HT neutral lead and found with no such abnormality. Now the tap changer system was suspected as because of this path is associated with the HT winding. The diverter switch was lifted and found with debris and sludge on the lugs. The tap position connecting rod was also deposition of foreign materials. The same was cleaned and rinsed thoroughly with transformer oil with overhauling of the total diverter switch portion. Then the results were taken and found with normal value. The transformer was charged and loaded successfully. Note : So it can be noted here that for the case of abnormal IR value between HT-Body for any transformer, the common system i.e TAP CHANGER portion has to be overhauled before concluding the problem in the transformer. 2.2. 33 KV VCB with lower IR value : During annual maintenance of a 132/33 KV grid sub-station, one of the charged 33 VCB was tested for obtaining its IR value and found with the following results. Upper Limb- Lower Limb = 5 Mohm (VCB Open) Upper â&#x20AC;&#x201C; Body = 500 Mohm Lower- Body = 475 Mohm. Investigation and Analysis : During the measurement of IR value between Upper and lower limb, the path it takes as 1. The VCB chamber with gap between male and female contact 2. The external path through insulation stack.

So considering the leakage current tracking on the external path, the insulator portion was cleaned with dry cloth before taking the reading. So it can be suspected for the gap inside the VCB chamber. But with this lower value, the VCB can withstand to 33KV supply voltage as because of both male and female contact get close during charging condition. On opening condition the obtained value of 5 Mohm is also enough for arresting the leakage current flow from one contact to other. However it was advised for the change of the limb, such lower value may be due to the problem on the VCB chamber with moisture inside. Note : So it can be noted here that for the case of abnormal IR value between Upper- Lower terminal of 33 KV VCB, the gap inside may be lower or contacts might be burred or problem in the vacuum chamber. The limb should be replaced. 2.3. Abnormal actuation of DP relay : At a 220/132 KV Grid Sub-Station a DP relay (ABB make RAZFE type) on a 132 KV feeder was actuating abnormally with of no fault in the system. Investigation and Analysis : The feeder was taken shutdown for detail checking of the relay and observed with the followings. 1. On reach test, continuous actuation of the relay for the injection to RS and RST fault. 2. Non-actuation of the relay for T phase associated fault testing i.e TN, ST, TR. 3. So the T phase associated CT circuit from Line ||www.electricalmirror.co.in||

Ct secondary terminal to the relay point was checked a. The CT secondary circuit up to Auxiliary CT was found OK. b. But on removal of the relay cover to the access of the Relay auxiliary CT checking, it was found with dis-connection of 8 Nos of wires may be due to RAT biting. c. So these wires after circuit checking were connected as per the wiring 4. After connection, the testing was done again. This time it was observed with the followings a. Results for RN, SN, RS were obtained satisfactory. b. Results for RST came as 2 Ph fault indication i.e RS only c. Similar non-actuation of relay resulted with TN, ST and TR 5. So it was concluded with the problem on the internal auxiliary CT circuit of the relay. 6. So this auxiliary CT was replaced and detail internal PCB was checked by the service engineer. Finally after rectification of the problem, the relay was taken into the circuit and functioning satisfactorily till date. 2.4. Abnormal tripping of Transformer on Differential Relay : At one 220/132 KV Grid sub-station, one of the 100MVA Transformer with EE make DTH 31 type , differential relay was tripping abnormally during initial charging of the transformer. The relay setting of 2nd harmonics restraint of was 18%. Investigation and Analysis : Because of this behavior

||www.electricalmirror.co.in||

of the transformer, the testing of the relay was done for second harmonic feature. On testing it was with R Phase = 31%, Y Phase = 29% and B Phase= 15%. Hence it was confirmed from the values that B phase result is below the setting value. Hence on charging this phase was issuing the tripping command and for per phase actuation logic, all the three phase was tripping. Rectification : The relay was replaced by a new one and taken into service. 2.4. Abnormal tripping of Transformer on Differential Relay : At a 132/33 KV Grid sub-station, one of the 63MVA Transformer with Siemens make 7UT51 type , differential relay was tripping abnormally during initial charging of the transformer. The relay setting of 2nd harmonics restraint of was 15%. Investigation and Analysis : After tripping, the parameter values were collected from DR of the relay for detail analysis and found with calculation of total % 2nd harmonics as 44% and on average it is of 44/3 = 14.67 % Rectification : The relay setting of the relay was changed to 12 % and taken into the service. This type of setting and logic is called Average restraint tripping. So while selecting the restraint, the type of transformer and its magnetic behaviour has to be studied. 2.5. Burning of Closing Coil of 132 KV breaker : At 132/33 KV Grid sub-station, the closing coil was burnt during closing of the 132 KV breaker. Investigation and Analysis : The detail closing circuit of the breaker was checked and found with the followings.

i. The closing coil resistance was measured and found with OPEN condition. ii. The ANTI-HUNTING circuit was checked and found with problem in the operating coil and was not actuating for the condition of continuous extension of the closing command. iii. The remote TNC switch (Breaker Control Trip-Normal â&#x20AC;&#x201C; Close Switch) was found with continuous extension of Close command. Because of continuous extension of closing command to the coil and due to non-actuation of ANTI-HUNTING circuit, the closing coil got the continuous supply, for which the coil got burnt. Rectification : The Closing coil, ANTI-HUNTING coil and faulty TNC switch was replaced by good ones. The circuit was tested and found in order. 2.6. Abnormal PI value of transformer : During pre-commissioning period while taking the PI value of the transformer it was found with PI (Polarization Index) value more than 4.5. Investigation and Analysis : i. The factory test report of the transformer was compared and found with lesser value as compared to the field testing value. ii. The temperature conversion for IR value was done and found with similar trend. iii. Such higher value indicates regarding the condition of insulated paper. For the condition if paper insulation does not get proper impregnation, then due to dried nature the PI value may come high. iv. Some practice engineers do not prefer to energise the transformer, apprehending of catching fire on the volatile natured paper for

the case of sparking in the transformer. Rectification : This transformer was allowed with circulation of forced oil through the insulations by putting all the oil pumps ON for continuous way for two days. Then it was allowed to settle for 12 hrs. The forced oil circulation was done for the next continuous 24 Hrs for proper impregnation of oil into paper insulation. Then the PI was taken; now the value was obtained as 3.2 less than obtained value of 4.5. The transformer was enersiged and loaded with currents. It was advised to settle the transformer by keeping OFF, after loading the same for 2 days. The PI value was taken and found with normal value of 2.5-3.0. Then the transformer was allowed to take into service for usual loading of the system. 2.6. Reading on Neutral for metering scheme : For a 3 Phase 4 wire metering system, with no load condition and for the use of capacitor on R phase and Inductor on Y phase, reading was observed on neutral path. Note: - Capacitor and Inductor was used for control of Power factor in the system.

Analysis : i. The result as obtained on the snap shot is as follows.

ii. Ia= 12 (-330 degree), Ib= 9.2 (-138 degree), Ic= 3.2 (-180 degree). iii. The angle measurement in degree are based on the reference of zero degree, that could be

expressed with its own reference as Ia (lead to Va by 30 degree), Ib (lag by 18 degree to Vb) and Ic value showing -180 degree. iv. The use of capacitor on R phase to Earth and inductor on Y phase to Earth, results the leading and lagging of the current to corresponding phase voltage. But due to improper value of the capacitor and inductor, the magnitude of current is becoming different and not canceling each other. But the flow of certain current on B phase is resulting the current on neutral to zero. Now the resultant current of these values is becoming to flow on the neutral and magnitude is becoming as Ia= 12 (-330 degree) + Ib= 9.2 (-138 degree) + Ic= 3.2 (-180 degree)= 0.385 (-23.9 degree).

Visionary who Introduced BHEL into Steel Sector

Modernisation & Revamping of Hot Strip Mill, Rourkela Steel Plant. Visionary who Introduced BHEL into Steel Sector

Rourkela Steel Plant (RSP) established in 1955, was the first integrated Steel Works in India. As a part of this Steel complex, the Hot Strip Mill was commissioned in Feb’1961, to cater the country’s demand of Steel sheets, GI sheets etc. In the year 1976, RSP mooted out a proposal for diversification by setting facilities for Cold Rolled sheets with specific properties required for manufacture of Transformers, Motors, Dynamos etc. In order to meet the stringent requirements of the Cold Rolled sheet, it was necessary to revamp, upgrade & Modernize the existing Hot Strip Mill (HSM) (Fig.1 also, to meet the following new technological requirements. a) Rolling of Hot – Rolled Strips of Closer Tolerance. b) Rolling of Thinner gauges. c) Better metallurgical Control on the cooling & Finishing Temperature. d) Better Coiling facilities. e) An increase in Productivity with minimum alteration, that is the existing productivity of 193 Tons/Hr to be increased to 225 Tons/Hr. f) With the spurt in demand for consumer products such as Cars, Refrigerators, Washing Machines & so on, the domestic consumption of 46

Steel had also picked up substantially thereby boosting the demand for Flat products with high tolerance. g) In short, the Modernization & Revamping of Hot Strip Mill involved replacement of all

age-old Mercury Arc Rectifiers with Thyristor Converters for all the Six nos. Main Stand drives each of Capacity 3700KW DC Motors, Auxiliary drives ranging from 2.8 KW to 317 KW DC motors, 2 Nos. 1119 KW AC Motors, introduction of Hydraulic Automatic Gauge Control for controlling the thickness of the rolled Strip, provision of Load Cells, Width Gauge, Zoom Rolling Control etc.etc. The original Electrical suppliers for this mill were M/s Siemens & AEG, West Germany. Despite BHEL were in Power industry, they had not ventured into catering the more sophisticated requirements of the Steel Industry. Naturally, M/s RSP had no other alternative except to import the total Electrics & Automation Equipments from abroad. When RSP approached these German suppliers, they expressed that the total Revamping & Modernization period required was around Six / Seven months of shutdown of the Hot Strip Mill (HSM). Since HSM at Rourkela was the only plant meeting the Sheet steel requirements of our country, shutting down the Mill for such a long time would mean importing the material from abroad & the requirement of Foreign exchange which our country could not afford. Mr. V. Krishnamurthy, who was then the Chairman & CEO of BHEL (1972-77) was posted as Secretary to the Govt. of India in the Ministry of Industry (1977-80). (Fig.2). He knew very well that the country could not afford such a long period of shut

down of the HSM & wanted to encourage BHEL to take up this project & enter the totally new sphere of Steel Sector. A total shut down period of 45 days was allotted to complete the revamping & Modernization works. But BHEL had no experience / expertise in designing the sophisticated controls, automation etc. required for a Hot Strip Rolling Mill. BHEL had very good design personnel who could handle projects in Power Sector but Steel sector was totally a new arena. A new division called Industrial Systems Group (ISG) was formed in Bangalore and many of the employees from various divisions of BHEL were posted to handle the above project. Applications were also invited from persons having Steel Plant project back ground specifically to handle the Project execution works at Rourkela site. The selection committee had distributed a hand out giving the complete details of the HSM project & wanted the candidates to explain in writing, how they will plan to complete the project successfully, with in a span of 45 days shut down. The Project envisaged replacement of all the age-old Multi Anode Mercury Arc Rectifiers (MAR) feeding DC

Power to the Six nos. Mill Stands ( Each stand driven by 3700KW capacity DC motor) with Thyristor Controls. One technical hitch about the HSM project was that Rourkela Steel plant wanted to increase the speed of Mill production from 193 T/Hr to 225 T/hr. This called for increasing the speed of all the Six DC mill motors to get this increased output. Mill Stand numbers 1 to 5 had enough cushion to achieve this increased speed by suitably adjusting their Armature Voltage & weakening of the Motor’s Field Current. But in the case of Mill Stand No. 6, there was no margin left for increasing the speed. At the same time RSP had insisted that they did not like to order a new Mill motor with increased speed. In view of the above technical (Speed) limitation on Stand No.6, we had to remove this Mill drive (6th.Stand) & introduce an intermediate Speed increasing Gear Box between the DC Motor & the Mill, & re-erect the DC motor on a newly elevated Foundation (Fig.3 ). During this period, only Stand no. 6 would be taken out of operation, but the hot Strip Mill can still continue its productivity with the remaining five Mill stands, however producing steel sheets of slightly higher thickness. When I heard about the details of the above project, I was then working at M/s Visveswaraya Iron & Steel Limited, Bhadravathi, where we had a Combined Bar & Rod Mill having Fourteen numbers of DC Motor driven mill stands fed by Mercury Arc Rectifiers which had also become outdated. I was interested to work for BHEL on their challenging HSM project, & gain experience & come back to carry out similar replacement of Mercury Arc Rectifiers with Thyristors at Bhadravathi. I attended the above interview at BHEL. When the selection committee asked me that in the event I was posted (Fig. 3)

at Rourkela site to handle this highly time bound project, how confident I was, about the feasibility of the project in 45 days of shut down, I said, it should be possible, with a very good planning of all the activities. In fact during the interview I was informed that apart from BHEL, there were many more contractors working in other areas like Re-heating Furnace Modification, Civil Engg. Construction works etc.etc. connected with this HSM project. RSP had made BHEL totally responsible to act as the prime Co-ordinator for keeping up the total 45 days of shut down. My suggestion to the committee was that we need to divide the entire project into three phases, namely, ‘Phase A’, ‘Phase B’, & ‘Phase C’. During ‘Phase A’, we need to identify vacant areas along the length of the HSM & construct buildings & install all the new Thyristor Control & Automation panels and inter connect them with cables by planning new cable routes etc without disturbing the operation of the existing mill. The object was to maximize all the new installations during ‘Phase A’ without affecting the productivity of HSM. During ‘Phase B’, only the Mill Stand No. 6 will be shut down & the HSM will continue its productivity with the remaining Five stands. The 3700 KW DC motor of Stand No.6, will be dismantled, a new gear box would be installed & Motor would be re-erected on a newly laid elevated foundation. During this period, all the new cabling required from Thyristor panels & other automation panels for Stand No. 6 would also be laid & connected. Stand No. 6 would be commissioned with all its modernized controls. During ‘ Phase C’, the entire HSM would be shut down & balance Revamping & Modernization works of the remaining Five mill stands to be taken up & the entire mill to be commissioned within the 45 days. I had the unique opportunity of working on this project, posted at Rourkela site. Dr. V. Krishnamurthy from Delhi was periodically in touch with BHEL officials to ensure that things were moving in the right direction. In the light of BHEL entering into the arena of Steel Sector, certain new divisions had to be created for handling this. BHEL started a new division, Control Equipments Division (CED) in Bangalore to import Thyristor modules & other Automation controls from Siemens required for this project, Build panels & test them. Under the collaboration agreement with Siemens Germany, BHEL deputed a group of its own designers to Siemens Germany, & these engineers would design the modern controls required for the HSM project under the supervision & guidance of Siemens Engineers & get the designs wetted by them. Other than the equipments produced by BHEL in India, the rest required for this project ELECTRICAL MIR ROR

would be imported from Siemens. The most critical responsibility on BHEL was to ensure proper & timely co-ordination of activities during the 45 days shut down & ensure that no agency misses its targeted Schedule. It was almost 8000 activities to be monitored during the ‘Phase C’, which was humanly impossible. We needed the assistance an Industrial Engineer who can develop a PERT Network (Program Evaluation & Review Technique) covering 8000 activities as well as monitor the same on day to day basis during the shutdown period. Mr. B. P. Rao, an young Mechanical Engineer with PG in Industrial Engineering joined our group in 1978, exclusively for planning & monitoring of this Project. Incidentally Mr. B.P. Rao, after about 35 years of his valuable services at BHEL, served as the Chairman & Managing Director, of BHEL during 2009 - 2015. For day to day review of the PERT network, BHEL took the assistance of the IBM Computer

at Bangalore. In those days (Year 1979/80), no internet or Fax facility was available for transfer of data. We had to depend upon only the, then available, Telex system. Since BHEL had taken up the role of the Prime Project Co-ordinator, & the entire activities to be completed within 45 days of shut down, following methodology was adopted. Each morning, BHEL would hold meeting with all the contractors working on the project & based on the Computerized PERT network analyses, a days schedule of how much percentage of work to be completed on that particular day, by each contractor, would be distributed & again in the evening each contractor will submit a progress report giving the percentage of work actually completed for the day. This data received from the contractors would then be sent to IBM computers in Bangalore which would work out the new schedule to be completed by each contractor for the next day in order that the total completion of work is completed in 45

days. Mr. B.P.Rao stationed in Bangalore was coordinating this activity between IBM & our Project site. But for this kind of computerized PERT network monitoring system, completion of such a mammoth project with a fixed dead line of 45 days, involving so many agencies working at site would have been impossible The project was successfully commissioned by BHEL . With Mr. V.Krishnamurthy’s forethought & vision, & BHEL successfully completing its maiden Steel Plant project on schedule, (Fig.4 Finished Coils) its entry into Steel Sector became very smooth. As of now, BHEL ( Industrial systems Group) has successfully completed over 300 major projects in Iron & Steel sector alone, upto end March’2014. Thanks to the vision of Mr. V.Krishnamurthy.

Opening session of the 17th RPR; Gadkari Stresses the Importance of Having a Synergy Between Energy & Agriculture Sector The Independent Power Producers Association of India, today, inaugurated the 17th Regulators and Policymakers Retreat (RPR 2016) at The Lalit Golf and Spa Resort in Goa in the presence of the Shri Nitin Gadkari, Hon’ble Minister of Road Transport and Highways of India. The theme for this year is “India – Meeting the Aspirations?” The event looks at the aspirations of young Indians keeping in mind the ways of improving their living standards by benchmarking it to the western narrative of development. The ‘haves and have nots debate’ now has infected the entire population, thanks to the ever-increasing awareness amongst young India courtesy the information revolution. The retreat will go to the roots and examine the relevance, efficacy and practicability of the western developmental model in the Indian context. Mr. Nitin Gadkari while addressing the theme of the conference – “India- Meeting the Aspirations?” said: “We need to start an agricultural revolution in India using cheap electricity for farmers from pit-head power plants and urea produced using domestically available Coal Bed Methane (CBM) or coal gasification. Expensive urea imports from China would not be required.” “Innovation in water management including de-silting of rivers, using innovative check dams for micro irrigation rather than big hydro projects are required. “Referring to the viability of the power sector, he said: “how can coal prices vary without power prices correspondingly varying? The power sector would not survive.” “In the past, state governments have given too much importance on increasing the generation capacity without giving due importance to transmission and distributions segments in the power sector. With the advancements of new technology and innovations, significant growth is expected in the Indian Power Sector and the agriculture sector will be one of the beneficiaries of such growth.” “The government needs to focus on the agriculture sector and provide 24/7 electricity to rural areas at low prices. He also expressed confidence in the government’s plan to revolutionize the agriculture and irrigation sector in India.” He also said that some laws regarding environment and forests actually create hindrance in economic development. Further, Mr Gadkari, stressed the need for a transport revolution in India through development of Multi||www.electricalmirror.co.in||

modal transport using Inland Waterways 20p/km; Rail Re1/km; Road Re1.50/km, in that order of priority to radically bring down transport costs in the Indian economy. He said that there is also a “Need to develop India into innovation hotbed just like USA”. Union Railways Minister Mr. Suresh Prabhu, on a video conference, explained how the country is undergoing massive transformations in the Indian power sector through a pro-active approach and better policies and regulations. He said: “Rickshaw, Taxi & Train to be integrated in scheme for multi modal transport.” Mr. Piyush Goyal, the Minister of State with Independent Charge for Power, Coal, New and Renewable Energy, in a pre-recorded message, said that the UDAY scheme is the most significant step ever taken to remove the financial constraints in the distribution segment and will bring efficiency in the workings of the state electricity distribution companies.” Supported by the Ministry of Power, Ministry of Coal, Ministry of New and Renewable Energy and Punjab State Electricity Regulatory Commission, RPR 2016 aims to trigger out-of-the-box thinking by interspersing the intellectual and the esoteric with the day-to-day issues of the power sector to provoke thoughts and bring out creativity in the minds of policymakers and regulators. The RPR is a platform for engaging with cerebral persons in the industry and across sectors. It has won for itself a position of distinction and has been recognized as a confluence of innovative and informative flow of ideas and knowledge. The event spanning 3.5 days will include 10 sessions, 75 + speakers, 1 masterclass, 300 + participants, and 25 + awards. Key topics of debates and deliberations include: Meeting the aspirations – Infinite desires and finite resources; coal and power surplus – what stops Indian consumers from getting 24x7 power?; transmission challenges and the way forward; smart India – smart energy, smart water, smart transportation, smart security; civil nuclear liability – impact on fresh investments, development and mainstreaming of nuclear power; the roadmap and the challenges for solar and wind; and environment: India to meet the energy demands of 1.25 billion people through a low carbon trajectory/strategy?

Phase Verification in Power Networks

Incorrect phasing in power networks can have devastating and even deadly consequences. Yet phasing has, until now, been surprisingly hard to verify. This has changed with the introduction of an innovative phase verification system that makes use of the ultra-precise time-base provided by the signals from GPS satellites.

Phasing is often far from readily apparent. Sometimes there is no phase identification available, phase identification can be incorrect due to line transposition, crossover in joints or there could just be incorrect labelling of conductors or terminations. This can open the door to misunderstandings amongst staff, and dangerous phasing errors when adding new equipment, connecting or re-connecting a network. The consequences of incorrect phasing can be catastrophic. If a link is inadvertently made between two wrongly phased supplies in a power network, the instantaneous currents that flow are likely to be enormous. In a properly designed system the protection will operate very quickly, but in the very short time before this happens or if the protection fails, the energy produced by the fault current could damage or destroy equipment, and possibly even cause an explosion. It’s worth noting that phasing mistakes can lie dormant for months or years. Often open ring distribution networks incorporate switches. One of these switches can remain open in normal circumstances, but could be closed to reconfigure the network if there a need for planned maintenance or correcting a fault. Closure of such a switch will temporarily connect two supply sources that normally operate as two radial feeds into a closed ring. If the phasing is incorrect – possibly because of changes that have been made to the network since it was originally commissioned – the results can be dire. The solution to all of these problems is to use a dependable method of phase verification. Before discussing this, however, it’s important to emphasise one key point: phase verification is NOT the same as checking phase rotation. It’s perfectly possible to have two supplies that are phase displaced with respect to each other, yet have the same phase rotation. Phase rotation testing is no substitute for phase verification; for safe network operation, it is essential to be able to determine the ABSOLUTE phasing at every point in the network. Absolute phasing can only be determined when 50

- By Damon Mount - Power Sales Manager, Megger UK measurements are made with respect to a known reference phase. Unless the system is very small, this means that a two-part instrument is needed to make the measurement – one part to act as the base station that provides the reference information, and the other to perform the measurement at the point in the network where it is required to measure the absolute phase. This is the concept used in a novel phase verification system that is now available. It comprises two identical devices. One is configured as the base station and is connected to a low-voltage reference phase while the other is configured as the phase-measuring device, which, for convenience, can be referred to as the mobile device, as it will normally be used at a location remote from the base station. An ultra-precise timebase for synchronisation of the devices is established using signals from the GPS satellites that are more usually associated with satellite navigation systems. Synchronisation data is passed between the devices via the mobile phone network using a GSM module that can operate in standard data mode (circuit switched data, or ‘CSD’) as well as in GPRS mode. If the voltage for the mobile device is up to 400 V, you can connect directly to the phase that you need to identify. You can use the same connections when capacitive measuring taps on switchgear are available. For higher voltages, you could use a high-voltage sensor with wireless data transmission to the measuring device with an insulated pole approved for use at the appropriate voltage. If the base station is not connected to L1 as the reference phase, the corresponding correction angle of +120º or -120º must be entered into the mobile device. Also, depending on the application, there may be transformers with the same or different vector groups between the base station and the measuring device. These vector group shifts, which will lead to a particular phase shift, can then be entered into the mobile device in order to obtain the correct absolute phase indication. To cater for the widest possible range of applications scenarios, this innovative phase verification system offers four operating modes. NET mode NET mode is applicable when a low-voltage supply, such as a mains socket, is available at the location where the phase measurement is to be performed. In this case, the mobile device is connected to the low-voltage supply and a one-time synchronisation process is carried out with the base station. The mobile device determines the phasing of the low-voltage supply and uses this the local reference phase for all measurements carried out at this location. The low-voltage source must remain connected to the mobile device throughout the entire measurement

process. The major advantage of this operating mode is that GPS and GSM reception are only needed for a short period while the one-time synchronisation process is carried out. After that, all measurements are carried out with respect to the local reference phase, which means that the measurements can be performed very quickly. NO NET mode Where no local low-voltage supply is available – for example, when carrying out measurements on overhead lines – the mobile device operates from its internal rechargeable battery. If immediate phase display during measurement is needed in such cases, the mobile device must be continuously synchronised with the base unit via GSM, and GPS reception must be available. NO NET/NO GSM mode There are a few locations where no local low-voltage supply is available and there is also no GSM reception. To make measurements in these locations, NO NET/NO GSM mode is used. In this mode, when the measurement is being made, the mobile device stores only the GPS time signals and the voltage zero crossings. When the mobile device is subsequently moved to a location where GSM reception is available, post-synchronisation is performed – the absolute phase identifiers are determined and stored in a measurement file for later analysis. Post-synchronisation can be performed at any time up to 10 days after the measurement data is recorded. LOCAL mode In this mode, only the mobile device is used. It is connected to a local supply with a known reference phase, and all measurements are made with respect to local reference phase. No synchronisation with the base station is needed. The novel phase verification system described in this article allows safe, fast, and accurate phase identification at all voltage levels. The range of operating modes available makes the system convenient and easy to operate in virtually every application. The use of this system helps to eliminate the serious safety hazards associated with incorrect phasing in a network, as well as ensuring that documentation and any future additions will be correct. The ultimate benefits are, therefore, significant overall improvements in network reliability, efficiency and safety.

Inspecting Roof Mounted Solar Panels with Thermal Imaging

The sales of solar panels are soaring, which helps to reduce CO2 emissions at electricity plants. Over time solar panels may develop defects which can be easily fixed if detected on time, but can cause a severe drop in energy production and in some cases even start a fire if left unchecked. That is why more and more solar panel installers cooperate with experienced thermographers that offer regular thermal imaging inspections to ensure the safety and effective deployment of solar systems. As their temperatures rise solar panels become less efficient, producing less electricity. Some defects can cause them to break down or even produce a reverse current, which might damage the entire solar plant. Thermal imaging cameras can be used to detect hot spots in the panels from a distance, which makes it a lot easier to find defects before they become devastating breakdowns. The Italian solar panel installation company ELEM srl is one of the companies that is working together with Thermographic S.A.S. di Ermoni Alberto e C., an experienced thermographic inspection agency to offer thermal imaging inspections to their clients. This Melzo, Italy, based thermography agency offers thermographers with several decades of experience with thermography. One of these inspectors is Alberto Ermoni, a Level II certified thermographer. “Thermal imaging cameras from FLIR Systems are the ideal tool for the inspection of solar panels”, says Ermoni. “This inspection method is non-destructive and non-invasive. You can use thermal imaging to inspect the solar panels under load, so no shutdown is required. When used properly, thermal imaging cameras will show accurate temperature differences between cells or within a single cell that allow you to identify faults in an early stage.” Inspect the entire system These inspections are also not limited to the solar panels alone. “You can use thermal imaging to inspect the entire system, from the solar panels themselves to connections, inverters, fuses and all other electrical components in the system”, explains Ermoni. “If any part of the systems starts to wear down or develops a higher resistance for some other reason, the corresponding increase in temperature can be detected very easily with a thermal imaging camera, so you can fix the problem before the system fails.” The thermal imaging camera Ermoni uses for these inspections is the FLIR T640bx. “This camera combines top notch image quality with advanced features like wireless WiFi connectivity with a 52

Tablet PC and a wireless Bluetooth connection to selected Extech test & measurement tools with the MeterLink feature, such as the Extech EX845 clamp meter. These wireless connections really make a huge difference. Another feature that I use often is the Picture-in-Picture feature. This overlay of a thermal image over the visual image allows me to better localize the hot spots.” Wireless connection with Tablet PC or smartphone The FLIR T640bx thermal imaging camera contains a microbolometer detector that produces thermal images with a resolution of 640x480 pixelsandat

athermalsensitivity of 35 mK (0.035 °C). The ergonomic design allows the thermographer to look at objects from all possible angles. With its bright LCD screen and viewfinder it operates well, even in the sunny conditions that are ideal for solar panel inspections. The wireless WiFi connection between the FLIR T640bx thermal imaging camera and a Tablet PC or smartphone that is running the FLIR Viewer App makes it easy to show inspection results to clients on site and allows the inspector to produce reports on location, reducing the amount of time spent behind a desk.

This combination of several thermal images stitched together shows the entire photovoltaic installation.

The FLIR T640bx thermal imaging camera is the perfect tool for solar panel inspections.

This thermal image shows some defective cells within a solar panel. Overheating cells impede the performance of the entire photovoltaic system.

These solar modules show no defects, as their temperatures are within the maximum temperature specified by the solar panel producer as normal for operation in sunny conditions. The MeterLink connection over Bluetooth allows the FLIR thermal imaging camera to automatically embed measurements from selected Extech measurement devices with the MeterLink feature, making writing down the measurements on a piece of paper redundant. This not only speeds up inspections, it also reduces the risk of human errors. Interchangeable lenses One other very important factor in Ermoni’s choice ||www.electricalmirror.co.in||

for the FLIR T640bx thermal imaging camera is the fact that it has interchangeable lenses. “In some cases you are standing on a raised platform inspecting solar panels from a distance of 10 meters, but in another situation you might be inspecting the back end of panels from less than one meter distance. In these different situations you need different optics, a telephoto lens for the inspection from a distance and a wide angle lens for the short distance inspections. Many other thermal imaging camera models do not feature this flexibility in optics.”

Good solar panel inspections require more than just a good thermal imaging panel alone, however, Ermoni stresses. “Performing solar panel inspections properly can be quite a challenge. When you inspect the front of the panels you need to know how to choose the right vantage point and viewing angle to prevent reflections, , but you also need to know about emissivity and reflected temperature, if you want to get accurate temperature readings".

at the FLIR Infrared Training Center (ITC). “You really need this type of training to be able to deliver accurate reports”, says Ermoni. After becoming a Level II certified thermographer, Ermoni even became ITC instructor himself. “Having seen the importance of proper training in the field I am eager to share the knowledge I have gained with other thermographers.” To Ermoni the choice for a FLIR thermal imaging This Picture-in-Picture image and corresponding camera was an obvious one. “FLIR offers the whole package : very high quality cameras with advanced graph shows two line-analysis strings. The temperature measurements along these lines are features and excellent image quality, good software, similar and remain below the maximum limit. This very good after sales service and training courses to indicates that these fuses are functioning properly. match.”

Interview "Jo dikhta hai vo bikhta hai. Your logo is the face of your brand, it speaks trillions of things about your brand right from companies values, style, vision, mission, quality, growth, trust values, systems and many more things." Ms. BARKHA DATTANI || MD & CEO || BARKHAâ&#x20AC;&#x2122;s BRAND CLINIC

In todayâ&#x20AC;&#x2122;s World, for Any Sector competition is a part of Business. Do you feel which are the initiatives should be undertaken by Indian Industries to sustain in the competition ?

Today in India since 1900 the entry of International brands has impacted the approach of India brands in a big way, the standardization set by Govt. like ISO mark and likes has brought in uniformity in the quality of the products and services in India like ever before. The benchmark set by such competition from international arena has awaken the Indian brands to up gradation in every aspect of business. Because of which the importance of Brand, Logo, Packaging, Advertising has shifted the paradigm to presentation in a big way. The logical reason being the uniformity in products and services makes a clutter of generalization, so as to stand out of the clutter the look and feel, packaging, branding and logo started taking front seat in the annul budgeting of Indian companies. So, for companies to stand out, they need to keenly observe the need gap in the market as to what and how a niche can be created. 56

Secondly, they need to focus on how to position their brands in the market that would make them look different then others. Also the vision of the director - the captain of the ship show be crystal clear as to how to keep up with the pace by expanding, diversifying, innovating, upgrading technologically and likes. Its also importance to understand when and how to enter and exist markets, you see right timing is everything. Finally keep being focused on deliverance and understanding the changing mindsets of the target group.

What is a meaning and importance of MAKING OF BRAND engineering? What is a significance of eye-catchy, attractive and memorable Logos for the Industries and Other Sectors ?

A brand is basically nothing but understanding the mindset of your target audience and accordingly modifying your product and service as per the changing taste and preferences of your TG. Today brand and branding is everything, its said "Jo dikhta hai vo bikhta hai" (what you keep seeing is what you finally buy.) So building a brand is a day to day activity, everyday in everyway your brand is building.

Right from how your operator picks the phone and says "Hello Mr. Mehta how are you doing today, to the billboards put up on highways to how your office stationery is, how your Logo is designed everything and more is all impacting your brand image. Your logo is the face of your brand, it speaks trillions of things about your brand right from companies values, style, vision, mission, quality, growth, trust values, systems and many more things. As per Harvard University the impact of Logo on the sales volume is around 33.36%. So if your logo is good and designed with commercial viability angel that along with the overall importance of presentation, style and design then it does help the brand in the long run. i would take step ahead to say Logos has the power to make brands may it be any industry logo has the power and magic to impact revenues, may it be B2B, B2C, FMCG or any market. Logo has tremendous power in the journey of building brands and sustaining it forever.

What is your opinion, views on utility of Logos for Indian industries of any sector? Do you feel that implementing quality, attractive, attentive logos will help India Industries to compete globally ? ||www.electricalmirror.co.in||

Yes, positively good logo has immense power to building Great brands Logo when used rightly it has huge impact. Human minds register things mainly through vision effect, the memory of human being has maximum recall value when it stores things visually. So the power and strength of logos is huge not just in building brands but also in profits and revenue models specially in the era of Globalization a nice, attractive, impact full, quality and meaningful logo is essential.

Did you have interest of making of Logos and Brand Promotions Logos even before you went to college ?

I was impressed towards the business and moreover, I had the inclination since childhood. I started holding at the age of 16 and side by side, I also did B.Com. After that, I also did my MBA in Marketing from Wigan and Leigh College of London and some amount of business was also going on simultaneously. As soon as I finished my MBA, I full-fledged entered into

business.

Your father has a construction business. Normally, people enter into their own family business because they know from their childhood what they have to do. But in your case, it is slightly diďŹ&#x20AC;erent. How you derived and which was your first assignment ?

My father had always given me the freedom to do whatever I was passionate about or interested in doing. I always felt that the construction line was manly and I disliked roaming around in the sun and my father advised me to do what I enjoyed doing and I moved forward from there. My very first assignment that I got when I started this company was from a client in London and seven people together had given me a contract for seven logos. I got a very good boost that having just started the company, I got an offer that too from London for seven logos. That really gave a boost to my confidence. They were very happy with my work and they are still my clients and keep giving me business. So I started from there and it picked up. We always try to see that year after year, we

perform better and better. My main competition is with only myself to do better and better.

What is the scope in this field of "Designing and making of Logos" ?

It is unbounded; there is no limit to this. I see tremendous opportunities in this field. We have about nine offices all over India. It is the only company in the world for logos to have nine offices. I know in India, we are the only company. Very soon, we are going to enter Gujarat and tap the Gujarat market, even the remotest of the villages. We are going to tap Gujarat strongly. We are going to start our offices in every city of Gujarat. This is our mission at the moment. We are getting a lot of demand from there and it is an upcoming market. Lot of companies are establishing themselves there. Many people from Gujarat come to meet me here. Our work is going on full-fledged. Internationally also, we are planning to extend our brands to Dubai. We get a lot of work from Nigeria, UK and USA. We are planning to shortly open our office in Dubai as well. We get a lot of franchise offers as well. Lot of companies are interesting in having franchisee tie-ups with our company. We are in talks with lot of such

Interview companies. There is high potential. This is just the tip of the iceberg. This is just the beginning for us.

PR is a different concept and advertising is a different concept. According to you, what is the difference between advertising creativity and logo creativity? What is the difference and how it will be of help to your brand promotion and your advertising ?

In advertisement, the basic difference between both is that advertising is basically going to sell and resell your product through again and again coming in front of the people. But in our field, if I talk from an angle of logo designer, then lot of understanding of the mindset of the consumer is required. Lot of understanding and research work is required in understanding the taste, the colours, the fonts, the symbols which has a perception value to the client that they are going to position their product to. The difference between advertising and logo would be that we do intense research in terms of the fashion, in terms of the colour, in terms of local, how you are going to sell on day to day basis, how you are going to impact the heart and soul of the consumer. That needs to be understood and according to that, you need to differentiate and then you work. I would not hesitate in saying that advertising and all these things will sell your products once but it is only your product and products that resells itself.

What is the trend, practices in the Brand Promotionary Logos ?

It is picking up. The importance of brand is becoming immense today. In every industry, before starting the company, they come to us saying that they have to have a logo in the first place, then they have to decide their packaging. Now all these things are in

their budget. That is now a compulsory need to show the presentation. Before coming into the market, before they launch their product, they are well aware of the image of their brand. That is very important to them. That is very strongly focused in every industry irrespective of whether it is the film industry, pharmaceutical industry, clothing and so on. Today, even individual personalities come to us to design their individual logos when they go to Cannes Film Festival or wherever they go because their card is going to speak a lot about themselves. They give their card to showcase that they are somebody. That is becoming a strong trend today.

Now the Government of India is also using the Logos for brand image promotions which you have prepared. Tell us something about that!

We have done logo design for Mr. Narendra Modi for Water Integrated Watershed Management Programme. He gave lot of emphasis to logos. He thinks that half the work is done if the logo is good. He believes that. We have done their logo and they properly understand and respect the research work that went behind it. We have a huge research also going on which is very rare these days. We have

around 50 people who do the research for logos before it goes to the client like understanding colours, fonts, symbols. All these detailed meticulous planning is done before it goes to the client. Mr. Modi understands and respects all these things and then he only selected the logo. I was invited in the Indian Citizen Engagement Platform by the honorable Prime Minister Mr. Narendra Modi, to be held on 6th Aug 2016, in New Delhi for participating in the Indian Citizen Engagement Platform by the honorable Prime Minister Mr. Narendra Modi. Logo designed by us was awarded by Government of India, Ministry of Rural Development. We feel proud and honored to get invitation from Prime Minister Narendra Modi to be a part of Indian Citizen Engagement Platform. We are also happy for making and designing logo for Honorable Prime Minister Mr. Narendra Modi of the program “Integrated Watershed Management Program” by Government of India, Ministry of Rural Development, Department of Land Resources. Said Barkha Dattani. It will be very motivating to attend multiple panel discussion and first ever “Townhall” which is to be addressed by Honorable Prime Minister Mr. Narendra Modi. Further said Barkha Dattani.

Quick and Easy Three - Phase Testing of Power Transformers

New test system TESTRANO 600 : Compact, powerful, unique. With TESTRANO 600, OMICRON has developed the world’s first portable, three-phase test system, which supports all common electrical tests on power transformers. Weighing just 20 kg/44 lbs, it is ideal for routine and diagnostic testing on-site and during factory acceptance tests (FAT). In addition, its innovative design significantly reduces wiring efforts, cutting down testing time to one third compared to conventional single-phase testing. One system– multiple tests With TESTRANO 600, operators need just one common setup to perform multiple tests, such as transformer turns ratio, exciting current, DC winding resistance, dynamic resistance, short-circuit impedance / leakage reactance as well as frequency response of stray losses (FRSL). By combining it with the accessory CP TD1, it can also test power/ dissipation factor and capacitance up to 12 kV. The magic number “3” In order to work with TESTRANO 600, just three cables have to be connected: One to the

high-voltage side, one to the low-voltage side and one to the tap changer. Three integrated sources ensure measurements with high accuracy and make TESTRANO 600 a powerful test system (3x 33 A DC and 400 V AC). Compared to conventional singlephase test sets, a true three-phase test system offers several advantages, such as shorter testing times when energizing all three phases at once, and a fully automated control of the tap changer during testing. Flexible and smart operation In order to fulfill individual customer requirements, TESTRANO 600 offers a flexible operat-ing design. It can be operated via the smart TESTRANO Touch Control on the integrated touch display or by using the established Primary Test ManagerTM software on the laptop. Active discharge & quick demagnetization The controlled discharging function (patent pending) of TESTRANO 600 automatically dis-charges the

demagnetized core reduces the risk of high inrush currents and avoids the influence of a magnetized core on subsequent tests, such as excitation current tests or sweep frequency response analysis. Safety first TESTRANO 600 follows the “safety first” principles and is equipped with an emergency stop button as well as safety and warning lights. The unique connector plugs and the simple wiring concept with labelled connection leads leave an extremely narrow margin for wiring errors. Compact & rugged for on-site testing With all its accessories, TESTRANO 600 comes in a portable case and is easy to transport. Its rugged design makes it ideal for on-site testing even in rough operating conditions. All in all, TESTRANO 600 brings on-site and factory acceptance testing of power transformers to a new level – it has never been so quick and easy.

The integrated three sources and the simple wiring concept speed up and simplify power transformer testing.

winding within seconds, for example, after resistance tests have been per-formed. This increases efficiency and safety during testing. Operators can also quickly demagnetize the power transformer’s core before and after testing using TESTRANO 600. Demagnetization is recommended after DC has been applied on a power transformer, for example,during winding resistance tests. A
