Dear Friends,

Exploring the power potential in the North-Eastern Region of India has always been a challenging affair. If the resources available are properly developed, the region will not only be able to export power, but, over time, will also end up attracting investments in the kind of manufacturing in which uninterrupted electricity supply is essential. The estimated hydropower generation potential of the Northeast is huge, but capacity development is woefully short of the potential. The Total hydro-power potential in the region including Sikkim is 63,257MW, while presently; only 3% of the assessed potential has been developed in N.E. Region. This issue of IEEMA Journal takes a deep dive into the N.E. Region

power and development agenda. In consonance, coming April IEEMA is privileged to organise the 5th Eastern Region Summit - Konnect North East & Beyond at Guwahati, where we will focus on Capacity Building for Power Sector in NE India in terms of the seminar, besides an interactive exhibition spread over 20,000 sq. ft.

In the same month, the Metering India seminar will be hosted by IEEMA at New Delhi which will focus upon - last mile connectivity and consumer participation and initiatives like Demand Side Management, Renewable Energy Integration, ToD Tariff implementation, Consumer home energy management and Revenue protection for the utility. The seminar is envisaged to strengthen the technological choices and offer the options to empower and utilize existing infrastructure for a result oriented future. In partnership with all stake holders, let us add a Smart Indian Dimension to our future and endeavour to lead the global trend!

With immense contentment I hereby announce the dates for the next ELECRAMA to be held in Bangalore from February 13 to 17, 2016. Going ahead from just discussing Transmission and Distribution, ELECRAMA-2016 will focus on much broader agendas conforming to core infrastructure sectors of oil & gas, cement, renewables, nuclear to SMEs. You will be hearing more from the ELECRAMA-2016 Organising Committee Chairman on this.

All our activities, re-assures us that the IEEMA brand lives and sustains its promise Your link to Electricity.

Best wishes.

Dear Members,

Let me take this opportunity to express my best wishes to everyone on the Founders Day of IEEMA on 25th February.

Sitting in the Mumbai office on the Sixty Eighth Foundation day, I reminisce the past while looking at a challenging future. Sixty eight years have witnessed IEEMA building itself block by block and many of you have been a part of the growth story.

Last year saw a number of new initiatives bear fruit. IEEMA reached out to its members one-on-one . Interaction with key Utilities have been undertaken. Intelect saw its birth. Engagement with the Government has increased considerably. The need now is to ensure that the efforts are sustained and incrementally shored up. Continued support and guidance from everyone has helped the Association steer through challenges with elan and achieve new heights.

It is now time to set our sights higher and channelise combined and synchronous efforts towards achieving new targets. Some of the thrust areas would be as follows:

a) Further strengthening IEEMA brand.

b) Evolve Elecrama-2016 witn enhanced international colour making it a true Global event.

c) Redefining value creation for IEEMA members.

d) Renewed thrust on joint ventures and strategic partnerships to be able to provide a launch pad for our members

India is truly at the cusp of change. The positive atmosphere is suitable for pursuing our members interests. Support from our elected representatives during continued interactions is an indication that we are treading the correct path. IEEMAs four point agenda submitted to the Government of India, that was mentioned in the last edition is being actively pursued and we expect to see a couple of welcome policy changes in tender procedures, vendor development and pricing. Our Association is committed to furthering member interests and make IEEMA a valuable partner in progress.

Looking forward to a challenging year ahead.

Dear Friends,

Today across geographies, Electricity and communication remains the common denominator for growth and development. Traditional means of establishing connectivity and providing sustainable energy remains a challenge, which is being met by a multi model approach thereby rapidly changing the dynamics.

The world is moving leaps and bounds in leveraging technology in all facets of electricity. Interestingly, India happens to be in the epicenter of this threshold change, given her phenomenal electricity infrastructure ramp up through traditional generation, transmission as well as alternate modes using renewables linked to micro & nano grids.

All topics relevant to global electricity have found resonance in the Indian context, right from UHV 1200kV to rural micro grids to intelligent electricity. India is truly the microcosmic representative of the diversity of challenges and solutions that exists in the global electricity sector. By the way, India today is the worlds third largest producer of electricity, a reminder of the growing clout of India in the global power equation.

ELECRAMA through the years has evolved along the contours of the sectoral landscape to reflect these dynamic changes in the ecosystem and today is poised to take a leadership position of a truly global platform for technology, product and knowledge

MESSAGE Aaditya R Dhoot Chairman - Organising Committee ELECRAMA-2016

sharing amongst all key stakeholders of the electricity ecosystem earning itself the status of a WORLD ELECTRICITY FORUM

The coming edition will witness the tectonic shift to that of a truly global platform where the global leaders, movers and makers of the power fraternity will come together to find answers to the rapidly evolving scenario in that of sustainable electricity transmission, distribution, consumption and conservation.

Operationally, the shift would be towards keeping an agile, technology led approach, starting with an online space booking system, exhibitor and visitor engagement portal. In addition, the experience quotient will definitely be accentuated and a host of business opportunities are in the offing. More global participation is guaranteed in all aspects of ELECRAMA.

Please feel free to contact me with your inputs and suggestions, which we assure, would be considered while working towards this global phenomenon.

A superlative event experience for all stakeholders is definitely on the cards!

Afterall, its ELECRAMA time, where power meets power!

Best regards,

(Aaditya R Dhoot)

Continuing with Prime Minister Narendra Modis focus on development of north-eastern region, as he said, We want development through energy sector and northeast Indias unemployment problems would be solved through this sector. Japan and Germany have also promised to help northeast India in various means.

The government has already identified 21 such key projects worth over ` 1 lakh crore for ensuring faster clearances to them. Out of these 21 projects at least 11 are power projects including 3097 MW Etalin Hydro Electric Project on Dri River and Tangon River in Dibang Valley in Arunachal Pradesh worth over ` 24,200 crores, 1800 MW Kamala Hydro Electric Project worth ` 20,141 crores and 2000 MW Hydro project on Subansiri River in Assam worth ` 11000 crore are some of the big projects for NE.

The power sector provides immense potential for the northeastern region. If the resources available are properly developed, the region will not only be able to export power, but, over time, will also end up attracting investments in the kind of manufacturing in which uninterrupted electricity supply is essential. The estimated hydropower generation potential of the Northeast is huge, but capacity development is woefully short of potential.

With the initiation of the North East Industrial and Investment Promotion Policy, the Central government practically made the entire Northeast a special economic zone in 2007, providing major incentives to investors, including 100 per cent tax exemptions and duty cuts, capital subsidies of up to 30 per cent and even insurance reimbursements. Private

investment has so far been elusive, mainly due to the lack of quality infrastructure.

Meghalaya Energy Corporation LtdTo get a better view of the situation IEEMA Journal spoke to Mr K N WAR, DIRECTOR (HRD), Meghalaya Energy Corporation Ltd. Mr K N WAR spoke about the prospects of Hydro power in Meghalaya, he says, The hydro power potential of the State of Meghalaya is 3000 MW which is about 3% of the total hydro potential of the country. Presently, the installed capacity 314.70 MW and about 64.0 MW capacity is under construction.

Sharing a comprehensive scheme for strengthening of Transmission & Distribution he says, The North East Region Power System Improvement Project (NERPSIP) is a comprehensive scheme to be funded by World Bank and Government of India. The scheme comprises of development of Transmission, Sub-Transmission/ Distribution system up to 33 kV. The work covered under Tranche I, for Meghalaya Power Transmission Corporation Limited (MePTCL), are broadly highlighted in the following table.

Speaking about the status of Reforms he says, The Power Supply Industry in Meghalaya had been under the control of the erstwhile Meghalaya State Electricity Board (MeSEB) from 21st January 1975. The Government of Meghalaya unbundled and restructured MeSEB with effect from 31st March 2010. The Generation, Transmission and Distribution businesses of the erstwhile Meghalaya State Electricity Board were transferred to four successor companies. The State Government issued a Notification The Meghalaya Power Sector Reforms Transfer Scheme 2010 thereby giving effect to the transfer of assets, properties, rights, liabilities, obligations, proceedings and personnel of the erstwhile MeSEB.

On 31st March 2012, Government of Meghalaya issued further amendment to the above mentioned transfer scheme, to transfer Assets and Liabilities including all rights, obligations and contingencies with effect from 1st April, 2012 to namely:

u Generation: Meghalaya Power Generation Corporation Ltd. (MePGCL)

u Transmission: Meghalaya Power Transmission Corporation Ltd. (MePTCL)

u Distribution: Meghalaya Power Distribution Corporation Ltd. (MePDCL)

u Meghalaya Energy Corporation Limited (MeECL), a holding company.

The Total hydro-power potential in the NER including Sikkim is 63,257 MW. While presently, only 3% of the assessed potential has been developed in N.E. Region. There are 143 HE projects with capacity of 57,167 MW identified by CEA/States in NER for implementation and monitoring. Out of these, 79 projects have been allotted in Arunachal Pradesh as on date: 75 projects allotted to private sector with capacity of 29512 MW and four projects for a capacity of 5870 MW are allotted to CPSUs.

Strengthening of the Intra-State Transmission and Distribution System The Union Cabinet chaired by the Prime Minister, Shri Narendra Modi gave its approval for the North Eastern Region Power System Improvement Project (NERPSlP) for six States (Assam, Manipur, Megha laya , M izoram, Tripura and Nagaland) for strengthening of the Intra State Transmission and Distribution System at an estimated cost of ` 5111.33 crore including capacity building expenditure of ` 89 crore. The scheme is to be taken up under a new Central Sector Plan Scheme of Ministry of Power (MoP). The scheme is to be implemented with the

assistance of World Bank loan and the budget of MoP. Presently, all the six NER States are connected to transmission network at 132 KV and below. The 33 KV system is the backbone of power distribution system in the six NER States. In order to reduce the gap between the requirement and availability of the

intra-state transmission and distribution system, it is necessary to provide 132 KV / 220 KV connectivity to all the six NER States for proper voltage management and lower distribution losses. Similarly, the distribution system in all

six NER States which mainly relies on 33 KV network would be strengthened substantially.

The Total hydro-power potential in the NER including Sikkim is 63,257 MW. While presently, only 3% of the assessed potential has been developed in N.E. Region. There are 143 HE projects with capacity of 57,167 MW identified by CEA/States in NER for implementation and monitoring.

North Eastern Regional Power CommitteeMr B Lyngkhoi, Director, North Eastern Regional Power Committee, Speaks to IEEMA Journal and gives an overview of the power sector of North East.

North-East is called as the Power House of India: Can you please share the prospects and problems and also overview of the power sector of North East.North East is termed as future power house of India. According to an estimate of the Central Electricity Authority (CEA) and private power developers, Arunachal Pradesh has the potential to generate over 57,000 MW of hydro power. More than 150 memorandums of understanding (MoU) for Mega dams have been signed in Arunachal Pradesh State alone. Some of the ongoing projects in AR. Pradesh are 2000 MW Lower Subansiri of NHPC, 600 MW Kameng HEP of NEEPCO, 104 MW Pare of HEP which are expected to be completed by 2016-17. The proposed 3000 Dibang HEP project, 1750 MW Lower Demwe HEP and many more will be coming up in future in AR. Pradesh.

The Manipur Government singed MoUs with NEEPCO to undertake 60 MW Irang HEP project at Irang ricer, 190 MW Pabram HEP over Barak River, 67 MW Chakha HEP at Barak River, Tuivai HEP over Tuivai River in Manipur. Policies, such as Manipur Hydro Power Policy, 2012 are also formed to promote mega dams across the North East region.

Apart from above, 726 MW of OTPC (ONGC Tripura Power Corporation) will be fully generated by February, 2015, then 750 MW of NTPC at Bongaigoan (One unit of 250 MW) is likely to be synchronized by March, 2015, 60 MW Tuirial HEP in Mizoram of NEEPCO etc. Apart from these many more projects are in the pipeline in NER.

Looking at these projects, it is clearly seen that NER will be the future power house of India. However, since NER is highly seismic zone of Category V, careful planning has to be carried out while constructing such big dams to avoid flash floods in downstream as well as environmental issues. Due to up-coming hydel projects- several thousand hectares of agriculture land will be submerged and this will aggravate climate crisis. This is a matter of great concern.

What are the plans to evacuate the power surplus of NER? Please give the details of comprehensive scheme for strengthening of transmission and distribution system in north eastern region? What are the Reforms & Restructuring Reforms in Power Sector?

North Eastern Region Power System Improvement Project (NERPSIP) for six (6) States (Assam, Manipur, Meghalaya, Mizoram, Tripura and Nagaland) for strengthening of the Intra-State Transmission and Distribution System.

The development of Transmission and Distribution (T&D) systems in the North Eastern Region (NER) has lagged behind both in terms of Inter-State and Intra-State connectivity. Taking this into consideration, the entire transmission system development in NER was discussed in detail in First Sectoral summit

30 March 2015

of North Eastern Council at Pasighat in Arunachal Pradesh in January, 2007 and accordingly, Pasighat Proclamation on Power was declared. Pursuant to this Proclamation, a Comprehensive Scheme was prepared for strengthening of Transmission, Sub-transmission and Distribution system of the North Eastern Region by Central Electricity Authority (CEA) in consultation with Power Grid Corporation of India Limited (PGCIL) and all the States of North Eastern Region (NER).

Based on the above Comprehensive Scheme, Detailed Project Reports (DPRs) comprising Transmission, Sub-transmission and Distribution systems upto 33 kV were prepared by PGCIL in Jan, 2010 for each of the six (6) North Eastern Region States namely, Assam, Manipur, Meghalaya, Mizoram, Tripura and Nagaland. Subsequently, Department of Economic Affairs had approached the World Bank in November, 2010 to provide US $ 1500 million of International Bank for Reconstruction and Development (IBRD) funding support to the scheme, in three tranches of US$ 500 million each.

Ministry of Power appointed PGCIL as Designcum-Implementation Supervision Consultant on 1st February, 2012 and asked PGCIL to approach the World Bank and commence project preparation. In order to structure the various elements of Transmission and Distribution schemes under first tranche discussions were held among the World Bank, CEA, States and PGCIL over extended period.

The elements were prioritized in such a manner that they could be implemented expeditiously due to relatively less constraints of Land Acquisition, Resettlement and Rehabilitation (R&R) and Forest clearance issues. Accordingly State-specific DPRs for Transmission/Sub-transmission and Distribution systems (33 kV and above) of six NER States were updated by PGCIL in January, 2014, keeping in view the latest requirements based on the ground situation in the States. As regards the overlying Inter State Transmission System (under Central

Sector jurisdiction), it may be mentioned that the existing system along with the transmission system under implementation for generation projects namely Pallatana, Bongaigaon, lower Subansiri, Kameng and the NER Strengthening Schemes II & III shall be

adequate enough to feed into the Transmission & Distribution system covered under this proposal.

State-wise details of intra-state transmission and distribution system (33kV & above) required to be implemented with the World Bank (WB) assistance under Tranche-I, are as below:

The project is proposed to be implemented through a Central Implementing Agency i.e. Power Grid Corporation of India Limited (PGCIL). PGCIL shall be paid a consultancy fee of 12% of the executed

cost as a Project Management Consultant (PMC). The consultancy fee shall not be charged on the cost of land and Rehabilitation & Resettlement (R&R) as recently done for balance two NE States under similar scheme for Arunachal Pradesh & Sikkim, for which investment approval was recently accorded by Cabinet Committee on Economic Affairs (CCEA) on 15.09.2014. The projects will be owned by the State Utilities, which would undertake Operation & Maintenance (O&M) upon progress ive commissioning of the projects at their own cost.

In-principle approval to the project proposal was accorded by the Planning Commission in September, 2011. The project is being taken up as Central Sector Project with 50% funding from GoI & balance 50% from The World Bank under IBRD.

An amount of ` 200 Crore has already been provided in Budget Estimate (BE) 2014-15. Savings accrued during XII Plan under the overall budget of Ministry of Power (MoP) would be used for funding this proposal, which has the support of Planning Commission. Fund requirement under XIII Plan shall also be appropriately provided for.

It has been envisaged that during the implementation of this proposal, the capacity of the State Utilities shall be enhanced to enable them to contribute significantly more during subsequent tranches, preparation for which shall be commenced after approval of the first tranche of the loan. To facilitate capacity building, it has been proposed that expenditure to an extent of ` 89 Crore shall be fully borne by Government of India (GoI). This shall be in addition to 50% share of GoI in funding.

The cost estimate of the project has been worked out as ` 5111.33 Crore at February, 2014 price level as summarised below:

The completion cost of the project has been worked out as ` 6092.10 Crore (including consultancy fee & service tax thereon) as per guidelines dated 6.8.1997 issued by Ministry of Finance considering the average increase of Wholesale Price Index

(WPI) (80% weightage) and Consumer Price Index (CPI) (20% weightage) for the preceding 12 months period.

The project is considered as a Central Sector project with 50% contribution from Government of India (through the budget of Ministry of Power) and 50% contribution

as loan from the World Bank which amount to ` 5022.33 crore plus ` 89 crore for capacity build ing expenditure to be funded by Government of India through the budget of Ministry of Power as mentioned in para above. The financing of the World Bank funding (50% contribution) would be as per the extant guidelines for the North Eastern Region i.e., 90% grant and 10% loan to be borne by the States. The States would also bear the foreign exchange rate variation corresponding to 10% of the World Bank loan.

What are the key issues concerning the power sector in the region?

Since the power generation in the region is hydro-thermal mix, the region will be power surplus soon in both hydro and lean hydro season. But the main concern is that power connectivity for all by 2020 as plan by Govt. of India.

The present power demand of the seven NE States is of the order of 2200 MW. As per 18th EPS (Electric Power Survey) report of CEA, the projected power demand of the region will be 2966 MW by 2016-17 and 4056 MW by 2021-22. Due to vast geographical spread of the States, the power demand is scattered over large distances. Therefore, it becomes necessary to provide 132kV connectivity to the distant locations so that power supply from regional grid may be extended to all over the State.

The proposal is a major step towards meeting the national objectives like power to all, especially in the backward North Eastern (NE) region for inclusive growth, through enhancement in access of consumers to Grid connected power supply, besides improving its availability, adequacy, reliability and affordability. This shall also increase per capita power consumption in these States, which presently varies from 240.3 Kwh (Assam) to 690 Kwh (Meghalaya) compared to the National average of 914 Kwh. The transmission portion of the proposal has been planned for absorption of power from the overlying regional grid and to feed it to different parts of the State. The Distribution portion has been planned to facilitate dispersal of this power to the final consumers.

Our country is heavily dependent on fossil fuels. More than 65% of power generation in the country is coal based. The coal, right from its mining to usage is extremely polluting the environment and is largely responsible for global warming. Otherwise also if the exploitation of the fossil fuels is continued at the present pace, the resources have be exhausted in decades time whereas energy security is key to the economic growth and welfare of any country, state. Therefore worldwide there is a trend to protect the globe against the ill - effects of excess exploitation of the fossil fuels and the countries are stepping fast towards non conventional, renewal energy resources like solar, wind, biomass, geothermal etc. World over research and technological developments are taking place to harness energy from the renewable resources and their economic viability is increasing

For any change, both motivation and mandate are equally important. So the central and state governments have been incentivizing, facilitating the investors/developers for establishing renewable energy plants and the regulators have prescribed for the power distribution entities purchase of renewal energy, at least a certain percentage of their total consumption, called Renewal Purchase Obligation. As of now it is an obligation for the Discoms as the purchase of renewal power is costing dearer than the conventional power. For example, the Rajasthan Electricity Regulatory Commission has prescribed the

following Regulatory Purchase Obligation ( RPO ) for the state Discoms :

Year Obligation expressed as percentage of energy consumption ( % )

Wind Biomass Solar Total

2104 15 6.80 0.70 1.50 9.00

2015 16 7.30 0.90 2.00 10.20

2016 - 17 7.80 1.10 2.50 11.40

By the year 2022, the above total percentage of renewal purchase obligation is expected to exceed 20%.

Hardly any state could so far fully achieve the target of renewal purchase obligation, perhaps. Even the state of Rajasthan which is leading in generation of renewal energy would not be able to fully achieve the RPO target for the year 2014 15. Rajasthans expected total energy consumption for the year 2014 15 is 62000 Million units and the maximum demand around 11000 MW. With the environment changing to business friendly and the country heading towards "Make In India", the power consumption across the states will increase at faster pace and so the regulatory purchase obligation to ensure appropriate energy mix. Rajasthan is blessed with huge potential of wind

and solar energy but due to uncertain, less reliable availability of the wind power, its effective cost to Discoms is higher compared to solar. So may be the case with other states also. The average annual and daily availability of sun in the state is 300 days and 12 hours respectively. The average generation per day per KW solar capacity is 5 6 units. Therefore higher increment to solar purchase obligation compared to wind shall be more economically advantageous to Discoms.

In the above backdrop and to harness the benefit of the maximum available solar intensity in the interest of the state, the state government has issued Rajasthan Solar Energy Policy - 2014. Under the policy the state government will encourage and facilitate investors and developers for establishing an aggregate capacity of 25000 MW solar power during the ensuing years. The solar power has an upper edge due to its characteristics like wholly pollution - free, easy decentralized generation.

There is a fundamental principle that a product will have maximum value (ratio of utility and price) if its raw material, all facilities for production and demand is at the same place. Such principle is more applicable to electricity as its transportation from the generating station to the end consumer suffers from inevitable T&D Loss besides the cost of transportation. More over the generation and consumption are simultaneous. Therefore it would lead to a most advantageous situation if the generation of electricity is technically and economically viable at the consumers premises itself and the roof top solar plant is the right answer. This can be conveniently installed on the consumers roof top or on the vacant space available at the consumers premises. It may be off grid or grid connected.

The roof top solar plants offer the following advantages compared to the distantly located generating plants :

1. Minimum expenditure (almost zero) on transmission and distribution infrastructure for that capacity.

2. Negligible transmission and distribution loss. In reference to the state of Rajasthan 140 units generated by a distantly located power station is approximately equivalent to 100 units generated by the roof top plant.

3. Installation as also the maintenance of roof top solar plants are labourintensive jobs and so would generate local employment.

4. Since solar power is available during higher demand hours of the day, it would optimize Discoms power purchase cost.

The state Discoms are approaching regulators for determination of tariff and regulations for grid connectivity of roof top solar power.

Jaipur Discom has also filed a petition before the state regulator for determination of tariff and grid connectivity regulations for One KW to One MW solar roof top plants.

Germany, the world leader in solar power having installed a capacity of around 28000 MW solar power is almost roof top. Every fifth house in Australia has a roof top solar plant with aggregate capacity of approximately 4000 MW. But India so far is reported to have a total roof top solar capacity approximately 285 MW only, although the worlds largest roof top solar plant of 7.2 MW capacity has been recently commissioned in countrys Punjab state. It is supplying power to Punjab state utility. As per an industrial survey, India has potential to install 41000 MW roof top solar power at commercial and industrial premises and approximately 35000 MW at residential premises by the year 2024. Roof top Solar Photo Voltaic Plants ( SPV ) of total capacity 2.5 MW have already been commissioned on more than 100 roof tops of Gandhi Nagar City of Gujarat and the state has declared installation of another 25 MW roof top solar plants for its Vadodara, Mehasana, Bhavnagar, Rajkot and Surat cities. Solar Energy Corporation of India (SECI ) has awarded a work contract for installing total capacity of 5.5 MW SPV plants on the roofs of Bengaluru, Delhi, Chennai and Gurgaon. All these plants are based on rent - a - roof model. The ministry of urban development has also launched a mission to install SPV roof top solar panels of aggregate capacity 100 MW over 629 central government buildings in 18 different states of the country through SECI. The state

of Haryana has made installation of roof top solar plants compulsory for a specific category, larger size residential, commercial and industrial premises with effect from September 01, 2015.

The roof top plant is beneficial to the premises holder consumer also. The premises owner may get rent from or share profit with the plant developer, may get power in the event of grid failure and a sense of satisfaction for contribution to environment protection. The roof top SPV are safe and do not cause any inconvenience to the premises holder. The investors/developers may be selected through a proper process by the states nodal agency or the Discoms. The tariff for roof top solar plants may be determined through competitive bidding or the plants may be installed under Renewal Energy Certificate(REC) mechanism. The power so generated may be purchased by Discoms. The Central Electricity Regulatory Commission has recently revised the floor price of solar REC to ` 3.5 per unit and the central government

has proposed amendment to the electricity act 2003, making stringent provisions for non-compliance to RPO. The amendment also proposes several incentives for renewal energy generation. As a result of continuous research in India and abroad, use of advance technology and available incentives, the capital cost of solar plants is

decreasing every year where as cost of supply to consumers by Discoms is on the increasing trend. It is expected that by end of the another two years, cost of roof top solar power will be less than the cost of supply from the utilities. As on date the roof top solar is the most economical source for Discoms to comply with the Renewal Purchase Obligation. Looking to all such advantages we may call it energy for the future.

Overview of upcoming projects At present we are one of the leading manufacturers and pioneers in crimping technology (cable lugs and crimping tools) both in the local as well as export market. However we would like to broaden our cable accessories

range to include brass parts like cable glands, machined components, switch gear parts made from copper, and finally snap-on terminals for the automobile sector.

Priority areas We are focusing on the US market and of course the local market. The US economy is on a rebound and we feel the time is right to aggressively market our products there. We have already obtained UL certification for hundreds of products that are typical to that market.The Indian market is on the cusp of exponential growth and we would not want to miss the next wave of growth which should begin very soon. We are expanding our marketing effort and also our sales force and dealer network.

Projects in pipelineApart from the aforementioned projects, we are giving impetus to Bimetallic Lugs and Connectors. We are glad that the Solar and Windmill industry is adopting this component, as it is technically superior to conventional lugs. For the export market we have developed and are expanding our Split Bolt range, which is a product that finds application in grounding.

Expansion plans Seeing such a good demand in bimetallic lugs, and judging by the number of power/renewable energy projects in the pipeline, we are contemplating to buy

another Friction Welding machine. In the second half of the year we plan to add 20 Power presses of various tonnages. We have already bought CNC lathe and milling machine to manufacture tailor made machined parts. Thus expanding upon our existing CNC machinery. Although we are optimistic about the growth in the economy, a certain amount of caution is due and we would be expanding in an organic manner. We already have a number of our processes automated and we are currently looking into innovative automation solutions and trying to adopt best practices into our manufacturing systems.

Challenges On the sales front the challenge we face is competition from the unorganized sector supplying cheap low quality lugs and terminals. We are trying to solve this issue by educating our customer about the dangers of using low quality copper lugs, however the market is majorly governed by price thus quality sometimes takes a backseat. On the manufacturing front the recurring problem faced every year is labour shortage and even when labor is available the quality and skill is much left to be desired. The government needs to improve the education infrastructure and we need ITI and engineering institutes to churn out quality technicians and engineers. In fact I feel this is one of the major areas where China has overtaken us. The labour rates there may be higher but the productivity of the workforce offsets the higher wage.

Five years planWe are targeting growth in revenues to the tune of 25% year on year for the next five years. Our strategy is in place and we need to focus on implementing the same on a consistent basis. Currently we are a major exporter as 80% of our sales is from the export market. We have 15-20% share in the local market and we would like to increase that to at least 50% in the coming years.

We face competition from the unorganized sector supplying cheap low quality lugs and terminals: ED, BEWL

The Current Transformers (CTs) are Instrument Transformers and are very vital equipments used on the HV, EHV and UHV level systems. These transform the Primary current (which is directly not measurable as being of HV/EHV levels) into Secondary current which is almost the replica of the primary current and can be easily used in the secondary instruments/equipments like protective relays, control panels, energy meters and for SCADA applications etc. Therefore the CTs are used as input devices producing secondary currents proportional to the primary currents within the required accuracy limits.

Theory /Principle of Current Transformers

The Current Transformer follows the principle of maintaining balance between Primary Ampere-Turns and Secondary Ampere-Turns. Thus the following Ampere-Turn equation holds good.

Ip x N p= Is x Ns,

Where; Ip= Primary current,

Np=Primary No. of turns.

Is=Secondary current.

Ns= Secondary No. of turns.

Kn= Ns/ N p, turn ratio or Transformation ratio.

Im=core magnetizing component.

Ie=Iron loss component, Io=Exciting current. =the phase angle of the Current Transformer. Note:

Np (No of primary Turns can be 1, ie it is a bar primary CT).

Following figures depict the basic connection of CTs:

Where

P1-P2 =Primary terminals,Ip =Primary Current, S1-S2= Secondary terminals., Is=Secondary Current, Im=Core Magnetizing Current,

RCT= Internal winding resistance of the CT,RB=Resistance of the connected Burden.

ZT= RCT + RB.

Note:In the above figure the Primary Turns have been shown,However in some CTs there is bar primary ie the CT has primary turn as 1 only.In such CTs the primary lead /conductor passes through the Toridal ring type core containing secondary winding.{Ref fig. 1.(b)}

Rated Burden: Output of the CT secondary to which it can feed maintaining the required accuracy stipulated in the Standards (IS: 2705 or IEC: 60044-1 etc)

Total Burden: It is the sum of the total burdens (in VA) connected to the CT secondary.

Total Burden in VA=I2x {(resistance of 2 x length of connecting lead) + Resistance of CT Secondary winding)} + VA burden of the meters/relays connected to it.

Note:

(i) In practice, in order to reduce the losses in the control cable of the CT, copper control cable of 4 sq mm is used between secondary terminals of the CTs from 220kV, 400kV and 765kV switch yards/sub-stations to the control rooms (due to very long distances) whereas other control cabling from switch yards to the control rooms is done with 2.5 sq mm copper control cables. It is for academic interest to know that resistance per Km of copper cables, of 2.5 sq mm is 7.41 Ohms/Km and that of 4.00 sq mm is 4.61 Ohms/Km at 200C. ( As per IS: 8130 -1984).

(ii) Resistance of Lead R lead = ( x L)/A, here (Rho) is the resistivity of copper as 1.79 x 10-8 meter at 200C and 2.16x10-8 meter at 750C.

L =2 x Actual length of the control cable lead from CT in the switch yard to the Relay. (2 is taken as it is twice lead length ie to and fro length). It should be in meters.

A- Area of cross section of the conductor in Square Meter.

Example: Resistance of 50 meter copper control cable with cross section area of 4.0 Sq mm used for protection purposes is calculated below;

R lead= ( x L)/A = (2.16x10-8x 2x50)/4x10-6.

Here 4mm2=4x10-6 Sq Meters,

L= twice the lead length=2X50 meters=100 meters.

R lead=

Dependency of secondary current on Primary current:

he primary current is independent of the secondary current. The secondary current is governed by the Primary current only. Vice -versa, it is not possible.

Effect of secondary open circuiting

Since in a CT Primary AT is balanced with Secondary AT, in a closed secondary circuit (Secondary circuit is closed through connected burden or directly) the counter flux produced by the secondary keeps the core flux below the saturation level and as the Primary current is independent of secondary current, the secondary circuit should never be allowed to get open circuited with the primary circuit carrying the current .In such situations the total primary AT is used up in magnetizing the core leading to its saturation. This results in increased EMF with voltage shooting up to a very high value depending up on the primary current which is hazardous to insulation as well as to human life.

Note: In practice, to facilitate shorting of the secondary, at the CT terminals in the C&R panels, the CT terminals are provided with shorting links and also sliding links.

Choice of secondary current

The CTs are generally available in 1 Amp or 5 Amp secondary current. It is the choice of the user to choose between them, but there are certain constraints due to which the secondary current has to be fixed for a particular application.

The CTs are though installed in series with the equipments (Motors/Generators/Transformers/Capacitor banks/feeders etc) installed at some distance ,the connections from the secondary terminals of the CTs are through leads/cables to the secondary protective relays /meters etc which are installed on the control & relay panels.

Where the primary current is high and the distance of the equipment is quite much(>30mtrs) as in the case of EHV Sub stations, the secondary current is selected as 1 Amp. Whereas when the distance of equipments is short (generally< 30mtrs) such as in small 33/11kV S/s, 3.3 kV, 6.6kV and 11kV indoor switchgears, 5 Amp secondary is generally selected.

The VA burden of the cable (Loss in the cable) imposed on the CTs is governed by to the resistance of the lead/cable and square of the secondary current flowing through it.

Say the lead (to & fro length) resistance is R ohms and the secondary current is of 1 amps. The VA burden imposed would be I2xR=1R=R VA, whereas in case of 5 Amp secondary current it would be

Distance of CTs from meter- 25 Mtrs (In EHV S/s yard)

4 CT ratio needed 100/5 A (Since distance is less than 30 mtrs., 5Amp is selected.)

Note: (i) CT rating should in variably be 120% of the Max rated current. Therefore 1.2 x 87.5=105A, Thus 100/5A CT would be suitable.

(ii) In order to rule out any confusion about connected ratio or also any mal practice by the HT costumer, most of the distribution Utilities are procuring single ratio CTs for HT Consumer metering application.

CT ratio needed 400/1A (though d i s t a n c e o f metering from the CTs is less than 30 mtrs, but 1 Amp is used as the secondary current for EHV CTs for all the core is 1 Amp only.

Note: ( i ) CT should have ratio of 800-400/1A, Connected to 400/1A (metering c o r e ) a l o n g with other cores for protect ion purposes etc.

(ii) Over load of 120% can be taken care of by this CT (CTs can carry 120% rated current continuously with defined accuracy limits).

PS Core

{ref. IS: 2705 (Part 4)} [Known as Px core as per IEC: 60044-1]: Though abbreviation PS is not elaborated anywhere, however it is assumed to be Special Protection Class CT core. This core is used particularly where current balance is required to be maintained. The turn ratio error is limited to 0.25%, which helps in maintaining current balance in Differential protections & restricted E/F protection, which is the prime requirement between associated CTs, particularly during through fault conditions. The 5P/10P class CTs cannot match the characteristic as that of PS class. The core of this class is such that very high current is needed for saturation of the core.

The CT of PS class is specified in terms of;

Rated Knee point voltage Vk .

Maximum exciting (Im) at knee- point voltage or at the specified fraction thereof.

Secondary winding resistance (Rct) of the CT at 750C.

Requirement of Vk (Knee point voltages) of some of the known Differential relays

(i) ALSTOM Make;

(a) Type DTH31/32(Static);

Vk 40xI (Rct+2Rl),

where Rct = internal resistance of CT., Rl = Lead resistance of cable from CT to Control panel(single length.)

(b) Type MBCH 12/13;

Vk 24 x In (Rct+2Rl), In =Relay rated Current.

(c) Type KBCH 120,130 and 140.

Vk 24 x In (Rct+2Rl), In =Relay rated Current.

(ii) ABB Make;

(a)Type RADSB;

Vk 30x In. (Rct+2.Rl+Rt+Zr),

In =Secondary Current corresponding to rated Primary Current.

Rct = resistance of CT secondary winding.

Rl = resistance of single lead from CT to relay.

Rt = resistance of interposing CT.

Zr = reflected burden of Relay.

(iii) EASUN REYROLLE Make;

(a)DUOBIAS-M (Numeric)

Vk 4xIf (Rct+2Rl), where If=3ph fault current limited by transformer impedance or high-set setting whichever is greater, Rct= CT secy winding resistance, 2 Rl=twice the lead resistance from CT to relay.

(iv) AREVA Make:

(a)MICOM P633, (Digital relay):

Vsat (Rop+Ri).k.I1,max.

Where;

Vsat =Saturation Voltage, Rop=Actual connected operating burden, Ri =Internal burden, I1.max = Non-off set max primary Current converted to secondary side,

k=Over dimensioning factor or Transient factor,

= 1+T, wherein =System Angular frequency and T=Primary system time constant ie L/R of the system.

CT Saturation:

The CTs are liable to saturate if the Primary current at the time of fault exceeds beyond its ALT limit. Such saturation may occur if the CTs have very low ratio and the fault current exceeds beyond 20 times of the rated current, in such cases the protective relays (O/C) become inoperative.

Please refer to the following figure 5 depicting

51

TechSpace

March 2015

wave shape of the secondary current at the time of saturation.

Fig. 5 : Steady -state saturation with AC current

To avoid saturation the CT should develop voltage such that Vk If. (Rb+ RCT+RL),

If= secondary fault current for fault at zone-1reach. (Amps),

Rb=Relay burden in ohms.

RCT=Resistance of CT winding in ohms.

RL=Resistance of lead (2xsingle lead length) (ohms).

Transient saturation

In the transmission lines, since they predominantly contain inductance, whenever fault occurs, the fault current contains component of DC current also. In practical applications, the DC transient current is in exponential form and does not sustain but decays in the time equivalent to the time constant L / R {Ref.fig: 7(a) below} , L is the inductance in Henry and R is the resistance of the transmission line in ohms up to the location of occurrence of the fault. However in practice full line length is considered for calculation purposes.

Due to the DC transient component of the fault current, the total flux in the CT core is distorted and affects the secondary current {Ref fig: 7(b) below} and the curve of CT current at secondary will be as shown in Fig: 6. As soon as the DC Transient vanishes, the steady state condition of the CT gets restored.

Fig.6 Transient saturation with offset current

Fig 7(a) Primary short Circuit current with DC component.Fig. 7 (b) Effect of DC component on CT Flux

As has been mentioned that the DC transient persists for a period of about the Time constant TN of the Transmission line {ref Fig: 6(a)}, care should be taken while procuring/selecting CT for faithful operation of the Distance relay. The Vk should be should be as follows.

This formula for Vk shall take care for the transient DC decay time of all kV class of Transmission lines. The CT should develop voltage such that

Vk If. (1+X/R). ( Rb+ RCT+RL),

Where,

X =System Reactance (ohms), R= System Resistance (ohms).

If= secondary fault current for fault at zone-1reach.(Amps),

Rb=Relay burden in ohms.

RCT=Resistance of CT winding in ohms.

RL=resistance of lead (2xsingle length)(ohms).

The term (1+X/R) is an additional term as compared to requirement of development of voltage to avoid saturation in case of AC saturation (ref equation in para.17).

Ratio Selection

Required CT Ratios are selected from reconnection of Primary Terminals in majority of the cases, However in some cases the ratios selection is provided at secondary terminals. Further, in some cases the ratios are selected reconnecting primary terminals as well as from secondary terminals (as the case may be).

i) Selection through Primary terminal reconnection: If there are 2 ratios say 400- 200A/1-1 A.

ii) The reconnection at primary terminals is such that for lower ratio the winding shall be in series and for higher ratio, the reconnection is such that the primary current shall get a parallel path.

iii)Following sketches depict the ratio selection of ratios at primary terminals as well as through secondary terminals;

iv) For higher ratio reconnect the primary terminals to P1-C1 and C2-P2 and for lower ratio C1-C2{ref fig8(a)}

v) Each core is identified with the prefix numerical number. eg core1:1S1-1S2, core 2: 2S1-2S2, core3 : 3S1- 3S2, core 4 : 4S1-4S2 & core 5 : 5S1-5S2 etc.

vi) Where selection of ratios are in secondary only the lower ratio shall be 1S1-1S2, 2S1-2S2 etc and the higher ratio shall be 1S1-1S3, 2S1-2S3 etc.{Ref Fig:8(b)}

Vii) Fig.8(c) depicts the ratio selection through both Primary and Secondary terminals.

It has become a practice to compact stranded conductors passing though die or shaping rollers. This is to reduce the diameter as well as smoothen the outer surface of conductor in one go. In case of Medium Voltage and High Voltage Cable smooth outer surface facilitate in reducing electrical stress on the surface of conductor. Compacting though make the outer surface somewhat smooth but due to pressure and drawing force the edges of wires as flattened becomes rough and uneven. These edges develop stress at the corner of the wire and at times can become a vulnerable point. To obviate such a potential high stress point, segmental smooth wires are drawn and stranded over the inner round contour thereby eliminating the danger of any undue high stress point.

This method avoids sharp edges on the outer wires and possible damage which may be caused to inner layers by the compacting pressure, while also ensuring that the flexibility of normally stranded conductor is retained.

This practice was introduced long before in UK and Europe for EHV Cables and also for overhead conductors.

Design consideration

Calculation of Segmental wire shapes:

The segmental wire shapes required to form a smooth conductor exterior can be calculated mathematically. In the following solution employed by the theory that

is first propounded and a design procedure based on this is then set out.

The following Symbols are used throughout theoretical design calculations:

R = Inner radius of segmental layer.

Z = Outer radius of segmental layer.

t = Thickness of segmental layer

= Lay angle of segmental layer

1 = Lay angle of inner surface of segment

2 = Lay angle of outer surface of segment

l1 = Lay ratio of inner surface of segmental layer

l2 = Lay ratio of outer surface of Segmental layer

P1 = Inner radius of segment

P2 = Outer radius of segment

G1 = Clearance of inner surface of segment

G2 = Clearance of outer surface of segment

C1 = Inner chord of segment

C2 = outer chord of segment

r = Radius of segment corners

A = sum of segment areas

1 = Half the angle subtended by C1 at P1

2 = Half the angle subtended by C2 at P2

L = Lay length

L1 = Lay length of line at right angle to the segmental

L2 = Lay length of segmental wire

TheoryConsider a layer of N segments stranded round a core of Radius R. Let the radial thickness of the layer be t and the lay angle . Figure-1 depicts one of the stranded segmental wire.

Now consider a section through the figure at X-X and the axis of the segment at right angle. This section is shown in fig-1

i.e. = N

Wire hat would be covered by a longitudinal straight line of the length i.e.)

Generalising from Fig- 1

(lay angle )

Or

And

Therefore, the number of wires cross by the line = N (1+ tan2)

Assuming no clearance between the wires, the length of the inner arc of the segmental wire is:

Length of the helix=

Rad.

Figure 2 shows the inner curve of the segment of known radius and arc length. From which:

Therefore, The inner chord of the segment C1 is given by: C1=Rsec

2 1 sin1

Similarly for the outer chord:

C2 = 2(R+t)Sin2

iii) Relationship of segmental layer radii and total segmental area: Consider a cross section through the stranded cable as shown in Fig-3

iv) Area of the annulus is = (Z2 R2).

If A is the total of the individual wire areas, then sine the wire have a lay length the total sectional area of the wires when cut perpendicular to the conductor axis = A Sec

The remaining area of annulus consists of the gap due to the clearance and the space left by the rounded corners of the segments. The space left by these rounded corners is almost the same as the area left by a circle of radius r drawn inside a square of side 2r. This is (4 ) r2 = 0.858 r2 . The area left by the radiuses corners of N wires, cut an angle of 1 is:

0.858 N r sec

The clearance between segments has a constant angle. Therefore, the fraction of the annular area taken

by clearance is:

Note: Although is used here in place of the strictly accurate , this does not introduce any significant error. We can therefore write:

The dimensions of the designed segments are shown in the fig-4

v) Area of Segment:

Corners of the segment shown in Fig- 4 have a radius of r. A formula for the area can be derived as follows:

Area of trapezium QPYX = AB x =

vi) Area between chord:

QP and arc QS2P = area of sector OQS2P area OQP= ; area lost due to radiused corner S = 0.858 r2. Therefore Segment area is:

vii) Lay Ratio : In cable design , lay ratio is defined as the lay length of a layer of wires divided by the mean diameter of the layer. It is therefore:

tan = vii) Design Procedure:

a) Select Values for the constants: R, N, t ( and hence ),G1 and r

b) Select a value for A or Z according to whether the design aim is given overall diameter or a given total area.

c) If designing for a given overall diameter work through the following formulae.

1) (hence 1)

2) (hence 2)

3)

4)

5) (To give constant angular clearance)

6) rad

7) rad

8) C1=2P1sin1 - G1

9) C2 = 2P2sin1- G2

10) t = Z R

All the segmental dimensions are now known.

d ) Check the dimensional area using the formula:

Area = {t+p1 (1cos1)

- P2(1-cos2)} +P22(sin2-cos2)

-P21(1 sin1)-0.858r2

e) If designing for a given area first determine Z from the formula:

Then to proceed as detailed in (c) above.

Manufacturing of conductor with Profiled Wire

Profiled Wire Drawing

As shown above once the design parameter of profiled wire is established, wire can be drawn in a normal 13 Die Wire Rod breakdown Drawing. Die should be made of Tungsten Carbide material. The Die is to be profiled in a spark erosion Machine and should be flawless. In the above case, the profiled wire can be drawn from 9.5 mm Wire Rod. Shaping is to be done during last four stages. Take up shall be done with proper guide system to keep the profiled wire always on the same plane. The wires can be accepted on 630 mm Bobbin DIN Standard.

Stranding

The profiled wires are placed on the front Cage of the stranding Machine. Lay gear is adjusted as per calculation. The wires are to be guided through a front guiding plate and then to be led through a cone type front guide system as is done in the case of a Flat strip Armour wires. The front of the cage is to be modified accordingly. Care to be taken that that the profile wires do not turn obliquely. The profile wire guiding system thus must be modified accordingly. Profiled wire will set plainly in place while passing through the Die fixed on Die holder box. Never use a split Die. A bell mouth Die is suitable for this purpose.

ConclusionFigure-5 shows a typically stranded smooth body conductor as manufactured with profiled wires.

} To manufacture such profiled wires and stranding do not require any special Machinery or equipment. Conventional RBD and stranding Machine with slight modification can yield the best result.

} Due to smooth surface Electrical stress developed is contained to the minimum values.

} During Extrusion of Semiconducting layer thickness can be maintained at a lower level and consumption of the material will be less as there will be no interstice filling required.

} So also thickness and roundness and ovality can be contained to a well within specified value.

} Overhead ACSR, AAC and AAAC can also be manufactured in the same manner. In such cases vibration due to high wind is kept within limited values.

} Diameter can be reduced by applying two successive layers of stranded Flat strip wires.

} In India such conductors for MV, HV and EHV Cables can be adopted to improve processing parameters and quality standard rationalising raw material consumption.
