Budget 2016 : Brings Mix Situation for Power Sector
The Finance Minister Shri Arun Jaitley has announced the budget for Financial Year 2016 to 2017 on 29th February. The budget brings mix up situations for the power industry. In the budget the government has taken various initiatives for the revival of power sector by providing financial assistance to the power distribution companies. The power generation sector is estimated to grow at 5.9 percent during 2016 to 2017. The government has also announced the extra benefits of additional depreciation at the rate of 20 per cent of the actual cost of the new plant and machinery extended to taxpayers engaged in the business of transmission of power. The 100 percent rural electrification scheme announced by NDA government in its first budget will be implemented by the government by 1st May 2018 as per the announcement made by Shri Jaitley. This scheme will give a boost to the power transmission companies. There is one more announcement was made, a Public Utility Bill to be introduced to streamline institutional arrangements for resolution of disputes in public utility contracts. If the proposed bill is able to address disputes surrounding power utilities, then this will be a positive for the sector. These are the glad announcements for power sector from budget but there is some bad news also. The Clean energy cess is announced to be double on coal, lignite and peat from Rs.200 a tonne to Rs.400 a tonne. If the cess will be raised than the power generation cost will also be increased automatically. As per ICRA, the cess can increase cost of coal-based electricity generation by about 10 paise per unit. It will crimp margins of merchant power producers who do not have long-term power purchasing agreements. Please give us your feedback at editor@electricalmirror.in

Zimbabwe-India Venture to Build 30 MW Hydro-Power Plant Zimbabwe’s state-owned power producer has picked a local company and two Indian firms to build a $128 million hydro-power plant to generate 30 megawatts of electricity, an official said.
Bharat HeavyBSE -3.07 % Electrical Ltd and Angelique International Ltd would build the Gairezi power station to the east of the country. The plant is expected to take 30 months to complete.
The Southern African nation last year experienced crippling power cuts but supplies have since improved from January after Zimbabwe resorted to imports from South Africa and Mozambique.
“The project will start as soon as we reach financial closure. We expect the money to come from Afreximbank,” Gwariro told Reuters, referring to Africa Export and Import Bank.

Chandigarh May Make Solar Rooftops Must for All Houses Chandigarh may soon make solar rooftop plants mandatory for all houses and buildings occupying plots larger than 100 square yards in a first of its kind clean energy drive in the country. A notification to this effect is expected shortly, said Santosh Kumar, director of Chandigarh Renewable Energy Science and Technology Promotion Society (CREST ), an arm of the union territory's department of science and technology.
"They are likely to issue it within this month," said Kumar.
CREST is in talks with Chandigarh administrator Kaptan Singh Solanki to get the urban planning department to issue a notification to this effect.
According to the proposal, houses on plots of 100-500 square yards will have the option to install either a 1 kW solar plant or a 100-litre solar heating system. Larger houses will have no such choice. Those on plots of 500-1,000 square yards must set up solar rooftops of 1 kW, while those on 1,0003,000 square yards will need 2 kW solar plant and those above 3,000 square yards must set up 3 kW solar plant. A 1 kW solar plant would generate 4-4.5 units of power a day. Haryana had passed a similar order in early 2015, but only for new buildings occupying more than 500 square yards.
'Happening Haryana' Investment Summit Sees Rs 80 K crore Worth of Proposals from Renewable Sector The renewable energy sector has made business commitments worth Rs 80,000 crore at the ongoing 'Happening Haryana' investment summit. The proposals include investments in solar, biomass, micro hydroelectricity and waste-toenergy projects. "The investment proposals (from the sector) have far exceeded expectations and even 22 ELECTRICAL MIR ROR

surpassed those in industrial investments," a top source from the Haryana government told, speaking on the condition of anonymity as these are part of elaborate announcements to be made later by Haryana chief minister Manohar Lal. Under its upcoming solar policy, the Haryana government is set to offer industry status to the segment with a bouquet
of financial exemptions and single-window clearance. The state will open panchayat land, irrigation canals and government buildings for investors to set up photovoltaic projects. A special scheme for solar water pumps is part of the policy. A price preference of 2% will be extended for solar power producers with 1-2 MW capacities.

SA 30i+ is designed to work under the hostile electrostatic noise found in live EHV switch yards upto 765 kV.
The main focus of this product was to provide wireless CT for leakage current measurement and wireless field probe for system harmonic measurement to ensure human safety. Mainly the field probe has to be raised up to the base of arrester. If the field probe is raised above the base, dangerous voltage can appear on the probe and may be harmful to the person testing the arrester. But with the wireless field probe, in such condition the voltage does not reach to the base instrument and safety of operator is ensured. This battery operated, light weight, reasonably priced portable instrument can become important tool to assess the surge arrester.

COVER STORY
Smart Grid : Highlights of India’s Mission, Market and Status of Pilots
“People are often confused by the terms Smart Grid and smart meters. Are they not the same thing?-Not exactly. Metering is just one hundreds of possible applications that constitute the Smart Grid.” This story will help to understand more about the Smart Grids.” - By N.P.K Reddy 32 ELECTRICAL MIR ROR

Smart Grids (SG) have emerged as the top infrastructure upgrade program in most developed countries in recent times. It encompasses different technologies that can completely transform the way electricity is generated, transmitted, distributed and consumed. It has the potential to innovate business models that can change the electricity utility landscape. These technologies are vital to meeting India’s vast and growing electricity needs. We need an Indian smart grid model that can engage our country’s particular operating conditions, and address her priority challenges – curbing transmission and distribution losses, and enhancing access to reliable, quality power for the common citizen thus providing lifeline supply to all households. In the face of rising citizen aspiration and demand, smart grid technologies offer India the tools needed to engage and overcome some of these challenges. World over, advanced countries are promoting smart grid technologies for both modernizing their aging grids as well as for transition towards low carbon economies by integrating renewable generation with the grid. Ministry of Power (MoP) had taken early actions towards grid modernization and leveraging the smart grid technologies. Accelerated Power Distribution Reforms Program (APDRP-I) during Tenth Plan upgraded the basic electricity networks in 56 urban circles across the country whereas Rajiv Gandhi Grameen Vidyutikaran Yojana (RGGVY) electrified about 56 million households in 100,000 villages. The ongoing Restructured Accelerated Power Distribution Reforms Program (R-APDRP) launched in the Eleventh Five Year Plan covers 1401 towns across all the state owned electricity distribution companies (discoms) and under this program the distribution companies are building their IT networks and a set of basic IT and Automation systems for the first time. And with the completion of these ongoing programs the basic building blocks of smart grids will be in place in all the electricity discoms in India and it is the logical next step to upgrade these systems to smarter grids that can monitor and control power flows in ||www.electricalmirror.in||
real time thereby mitigating demandsupply gaps during peak hours, reducing leakages in the electrical network and smoother integration of renewable generation and electric vehicles.While developed nations with reliable electrical infrastructure and minimal growth rates are concentrating on smart metering, tools for forecasting and despatch of renewable generation and analytics in their smart grid journeys, countries like India with weak and growing grid need to simultaneously strengthen the electric network as well as build additional layers of IT & automation systems to make the grids smarter. In much the same way, full implementation of the Smart Grid will evolve over time. However countless positive steps are being taken today, organizations energized and achievements realized toward reaching that goal. You will learn about some of them here. The purpose of this article is to give readers in plain language an understanding of the Smart Grid and its adoption. You will also learn what the Smart Grid is and what it is not. Smart Grid : What it is? - And -What it is not? The electricity industry is poised to make the transformation from a centralized, producer controlled network to one that is less centralized and more consumer-interactive. The move to a smarter grid promises to change the industry’s entire business model and its relationship with all stakeholders, involving and affecting
utilities, regulators, energy service providers, technology and automation vendors and all consumers of electric power.A SG makes this transformation possible by bringing the philosophies, concepts and technologies that enabled the internet to the utility and the electric grid. More importantly, it enables the industry’s best ideas for grid modernization to achieve their full potential. A SG is an electrical grid with automation, communication and IT systems that can monitor power flows from points of generation to points of consumption - even down to the appliances level and control the power flow or curtail the load to match generation in real time or near real-time. The increased visibility, predictability, and even control of generation and demand bring flexibility to both generation and consumption and enable the utility to better integrate intermittent renewable generation and also reduce costs of peak power. If the traditional grid was made secure only through over engineering, a smart grid is cost-effective, agile, responsive, and better engineered for reliability and self-healing operations. The conventional electric grid will need to build additional layers of automation, communication and IT systems to transform it to a smarter grid. Some of the applications or building blocks of a smart grid – some of which are already being deployed worldwide, including in India are – •

People are often confused by the terms Smart Grid and smart meters. Are they not the same thing?-Not exactly. Metering is just one hundreds of possible applications that constitute the Smart Grid. A smart meter is a good example of an enabling technology that makes it possible to extract value from two-way communication in support of distributed technologies and consumer participation. Further clarifying you, devices such as wind turbines, plug-in-hybrid electric vehicles and solar arrays are not part of the Smart Grid. Rather, the Smart Grid encompasses the technology that enables us to integrate, interface with and intelligently control these innovations and others. In terms ofoverall vision,the smart grid is : Efficient - Intelligent - Motivating Accommodating - Qualityfocused Opportunistic - Resilient - Green. National Smart Grid Mission A National Smart Grid Mission (NSGM) housed under MoP has been setup in Indian Power Sector to plan and monitor implementation of policies and programmes related to Smart Grid activities in India. The total estimated cost for all the projects and NSGM activities for 12th Plan is Rs. 980 Cr including a budgetary support of Rs. 338 Cr. The activities include development of smart grid in Smart Cities (Rs.890 Cr), development of micro grids (Rs.27 Cr), training & capacity building (Rs.8 Cr), consumer engagement (Rs.30 Cr) and NSGM establishment-O&M (Rs.25 Cr) etc. NSGM have a 3-tier structure. At apex level, NSGM will have a Governing Council headed by the MoP. The council will carry out approval of policies, programs, annual budget, review, audit and allied functions for SG implementation in the country. The
council meets on half yearly basis. At the second level the NSGM have an Empowered Committee (EC) headed by Secretary (Power) and carries out approval of specific SG projects, provide policy inputs, monitor, permit mobilization of resources, approve procedures/guidelines and other steps as directed by the Governing Council (GC). This committee meets on a quarterly basis. And in a supportive role, NSGM Technical Committee headed by Chairperson of Central Electricity Authority (CEA) carries out the tasks of developing standards, technical review of projects, technology selection guidelinesand other steps as directed by the GC/EC to meet the NSGM objectives. This committee meets as per requirement.

COVER STORY supported by GoI (Rs. 9.8 Cr) is expected to be completed by May 2016. SG Market to touch 50K crore in five years Smart grid is smartening up. The country is reviled to see the SG market touch Rs.50,000Cr in the next 4-5 years, from the present level of sub Rs.100 Cr. This would be boosted by the govt’s plan of setting up of 100 smart cities and 500 smart towns. Reliable electric grid is the most critical enabler for all other systems in a smart city. All the 100 smart cities and 500 smart townsis expected to haveSG’s in the next 5-10 years.The work would involve automating substations and distribution network, strengthening the electrical network, smart metering, rooftop solar integration, automated demand response systems to control certain loads match demand with supply, moving over head distribution lines to underground cables at strategic locations in the city, as well as state of the art Metering Billing and Collection (MBC) systems, energy storage systems, electric vehicle charging stations, integrated customer care centers, smart street lights and mobile work force management systems. Sources estimates that depending on the present condition of the equipment,a typical city of 5 to 10 lakhs population would require about Rs 300 to 500 Cr for modernizing the electricity grid. This would require investments to the tune of Rs 50,000 Cr for building smart grids in 100 smart cities. Similarly for 500 towns under AMRUT-program (Atal Mission for Rejuvenation and Urban Transformation), another Rs 50,000 Cr may be required at an average of Rs 100 Cr per town. Majority of the cities and towns have very high levels of network losses and other inefficiencies in their electric grids, henceforth grid modernization is required. This will result in huge gains in efficiency which will pay back the investment in 3-4 years. Efforts needs to be made to develop business models in which govt or utilities need not make upfront investments in implementation of SG’s. In-line with this a Model Smart Grid Regulations was approved by Forum of Regulators (FOR) in June, 2015 which is 36 ELECTRICAL MIR ROR

now being adopted by individual state electricity regulatory commissions (SERC’s). Assam and Karnataka Regulatory commissions have already issued draft regulations that are under finalization now and several other SERC’s are expected to notify the smart grid regulations soon. The selection of these cities (area-based-development) is done by the potential smart city proposals submitted by the cities. These cities used a combination of criteria for selecting areas such as economic activity, land use, land monetization, location of heritage and tourism areas, citizen-consultations, meetings with public representatives, desk research, analysis etc. It has been decided by the govt. that first year will have 20 smart cities, the second year 40 and the third also 40. Bhubaneswar, Pune, Jaipur, Surat, Kochi, Ahmedabad, Jabalpur, Vishakhapatnam, Solapur, Davanagere, Indore, , Coimbatore, Kakinada, Belgaum, NDMC , Udaipur, Bhopal, Guwahati, Chennai, Ludhiana, are the 20 smart cities chosen to be developed by the centre and have been selected for funding in the current financial year (2015-16). Five underlying technologies that will drive the Smart grid: •
Integrated
communications,
connecting components to open architecture for real-time information and control, allowing every part of the grid to both ‘talk’ and ‘listen’. •
Sensing and measurement technologies, to support faster and more accurate response such as remote monitoring, time-of-use pricing and demand-side management.
•
Advanced components, to apply the latest research in superconductivity, storage, power electronics and diagnostics.
•
Advanced control methods, to monitor essential components, enabling rapid diagnosis and precise solutions to any event.
•
Improved interfaces and decision support, to amplify human decision-making, transforming grid operators and managers quite literally into visionaries when it comes to seeing into their systems.
The ultimate success of the Smart Grid depends on the effectiveness of these devices in attracting and motivating large numbers of consumers. I hope that this article has given you a clearer understanding of the need for immediate and concerted action in the transformation of our nation’s electrical grid.

Gulf region, Mr. Kayhan Barzegar, Director, Institute of Middle East Strategic Studies, said: “The implementation of the nuclear deal and lifting of sanctions from Iran will strengthen multilateralism in Iran’s foreign policy and this opens a new vista of opportunity for both Iranian and Indian companies to start a new generation of joint ventures in energy and related sectors as well as coastbased energy hubs. With regard to energy security challenges, Ambassador Talmiz Ahmad, Former Indian Ambassador to Saudi Arabia, Oman and the UAE, said that the ongoing turmoil in West Asia constitutes a serious threat to India’s energy security interests and jeopardises its economic links with the region and the welfare of its 8-million strong community. “In this situation, India did not have the luxury of sitting on the fence while security in the region continued to deteriorate,” said Mr. Ahmad.

He strongly suggested that India should work closely with other Asian countries which had a similar abiding interest in regional stability to work together to promote engagement between Saudi Arabia and Iran, the estranged Asian giants in West Asia and promote a collective security framework for the region. The final day of the summit focussed on issues related to water management for India’s upcoming smart city program. Much like oil, water is fast becoming a scarce commodity, which may trigger flare-ups or even major conflicts in the future. Mr. Mahinder Sethi, Editor, National Institute of Urban Affiars, brought in examples from Asian cities like Singapore where they have succefullly managed to set up efficient water management systems. Experts also talked about China’s alleged construction of dams on rivers from which many of India’s major rivers like the Brahmaputra originate. Mr. Ajit Nimbalkar (Retired)
IAS, Former Chairman, Maharashtra Water Resources Regulatory Authority, brought in the regulatory aspect of water management and the various gaps that need to be addressed for regulation to be effective. This time the event saw considerable participation from the Middle-East including Dr. Mohammed Salih A. Almadi, OPEC Governor for Saudi Arabia. Other key speakers at the event were Amb. K C Singh, Former Ambassador of India to United Arab Emirates and Iran; General J. J. Singh (Retired), Fmr. Chief of Army Staff, Indian Army and Fmr. Governor of the State of Arunachal Pradesh; Mr. Narendra Taneja, Energy Expert and BJP Leader; Mr. Maulana Mahmood Madani, Former Member of Parliament - Rajya Sabha, Government of India; Ms. Sudha Mahalingam, Fmr. Member - PNGRB and National Security Advisory Board, Government of India; and H.E. Mr. Mirzosharif A. Jalolov, Ambassador of the Republic of Tajikistan to India.

Although, yet to create a strong brand reputation and recognition– some local Indian companies are also successful in expanding their business as resellers, distributors, manufacturers, or partnering companies in specific market segments. But today most market segments have high entry barriers due to the need for specialized design and development expertise, as well as the differentiation provided by proprietary technology. One key trend in the T&M market is the need for compatibility of test equipment and the demand for Smart handheld devices. The need for compatibility of test equipment is the main focus of T&M equipment vendors when developing new products. The continuously evolving technology has made the product lifecycle of T&M equipment short, thereby requiring new T&M equipment to test new technology. Henceforth this indeed has created a need for T&M vendors to develop new equipment capable of testing new technologies and also compatible with old technologies as well. The T&M market in India can be segmented into
three product segments: (1) General Purpose Test Equipment (2) Fiber Optic Test Equipment and (3) Wireless Communications Test Equipment. The analysts forecast the T&M market in India to grow at a Compounded Annual Growth Rate (CAGR) of 13.24 percent over the period 2015-19. The Indian market is very price-sensitive, and price is the first and foremost competitive factor. So to keep the development cost low, companies try to keep the testing costs very low. This is a big challenge for companies in the test & measurement space, as they spend large amounts to keep in line with futuristic technology trends to match the customer’s needs. Some other challenges include low availability of alternative testing mechanisms, lack of a structured ecosystem, high-end testing instruments are rented out in order to reduce capital expenditure,no or less clarity in governmental policies& regulations etc... One of the main drivers in this market is the increase in R&D investment. Advantages such as high growth potential and relatively low manufacturing costs help to bring more technological innovations through continuous R&D. One of the key challenges as discussed earlier that the market faces is price sensitivity of consumers buying T&M equipment. Customers in the Indian market place are very price conscious and tend to purchase low-priced T&M equipment at the expense of quality and added features. Some of the important drivers in Indian market include increasing demand for use from energy, ||www.electricalmirror.in||

There are three types of maintenance jobs on transformers a. Routine or periodic maintenance : For example, maintenance of OLTCs, after set number of operations or time frame b. Condition based maintenance : For example, improvement of the insulation values. c. Breakdown maintenance / repair : For example, failure of a bushing. Each one has different criteria to execute the work. The biggest enemy of transformers is moisture. If we fail to protect the transformer from moisture, the life of transformer may reduce to half or 1/4th in inverse proportion to moisture levels. Generally, Life of transformer = Life of transformer insulation. Degradation of insulation happens either due to moisture entry or excessive temperature of insulation. The combined effect of both can kill a transformer. Generally, the permitted moisture level in transformer is < 1% by DWOI. Transformers operating in the field above 2.5% moisture levels come under danger zone and 3.5 % moisture level indicates that transformer is lying on death-bed. Many transformers do not complete their rated defined life of 25 years due to various reasons. While many factors like design, workman-ship, operating conditions etc. play an important role, but degree of dryness and loading of a transformer defines its life. On the other hand, many transformers give satisfactory services for 40-50 years. This can be extended to 50-60 years by intelligent use. Routine and periodic maintenance is generally defined by the manufacturer and relevant standards. Breakdown maintenance does not give us time to act as per our wish and force us to adopt the shortest way to restore the power. It is condition based maintenance where we have to be very careful in pre-qualifying the transformer for a certain work. For example, it will be a stupidity to carry-out dry-out, 54 ELECTRICAL MIR ROR

Condition Monitoring and Site Maintenance of Transformers vacuum application and heating of a transformer in which DP value of paper is 300. Such a transformer, with a brittle insulation, can get damaged even if it is shifted from one place to another. An immediate wise action would be to reduce load on the transformer to extend its remaining life, rather than going ahead for overhaul work. RLA study can be done on a transformer to know its app. remaining life. The following tests must be conducted on a transformer for RLA: A. IR values/ PI values B. C & Tan delta values of windings and bushings C. Measurement of degree of dryness of a transformer by RVM or alternate method D. Magnetizing current drawn by transformer………. E. Impedance check F. DC winding resistance measurement on all taps/ all windings G. Sound and vibration levels H. SFRA I. Tests on oil: Water content / Specific resistance / Tan delta / Acidity / IFT / DGA / Furan analysis J. Status of OLTC K. Status of oil leakages No test alone can predict the future of a transformer. It is study of all tests and their co-relation which can bring out nearly accurate prediction, though operating conditions vary by a huge manner. For example, DGA can predict existing hot spots. The amount of key gases Methane, Ethane, Ethylene, Acetylene and their ratio / rate of rise can predict the fault in transformer. When this is co-related with furan analysis, which represents the DP value of paper, more accurate results can be obtained. By carrying-out RLA study, a planned action can be taken, unlike break-down maintenance work. Based on RLA study, the transformers will be categorized in following zones: A. Good zone B. Fair zone C. Danger zone 1, 2 & 3.
Transformers in danger zone 3 will require immediate attention to prevent their failure. Based on their condition, an appropriate line of remedial action will be decided. GEW Trafotech is introducing a mobile test van, which will be equipped with following instruments: a. Insulation tester b. AVO-meters and clamp testers/ Amp-meters c. C & Tan delta test set d. SFRA set e. RVM test set or equivalent f. Oil test kits for measurement of Acidity / IFT / Specific resistance / Tan delta / DGA Furans will be tested in the lab. The various remedial actions at site will be: a. Filtration only b. Dry-out by vacuum application combined with dry nitrogen purging and induction heating of transformer without lifting the core coil assembly c. Same as (b) with lifting the core coil assembly d. Attending other problems like oil leakages/ OLTC / RTCC / Fan circuit defects Once the transformers are dried and brought to an acceptable level of operation, it will be un-wise to again allow de-gradation of solid and liquid insulation system. To prevent degradation, it is recommended to install life extension devices on transformer.

Case
STUDY of The Month
VARIOUS CASE STUDIES ON OPERATION AND CONTROL SCHEMES FOR GRID SUB-STATION Contd…. 1. Introduction : For the last few months, the response of the readers to the case studies on various incidents is overwhelming. Hence this month we are again choosing the write up on similar kind of studies for developing the synchronisation of practical observation to the theoretical concepts. The analysis of each incident being supported by actual observations had been described during the situation to add awareness amongst the operation, testing and commissioning engineers to know the cause of problems and be helpful for easy rectification of the problems. This can also help to develop economic schemes for the smooth running of the operation and control system in the Grid Sub-Station. 2.1 Failure of PT : In one of the hydrostation after failure of one 6.6KV/110V, when another PT was replaced, the same was failed. On second attempt of replacement also the PT got failed. Observation : 1. Each time the failure was resulting on the primary side of the winding. So it was suspected with the supplied PT for this replacement. 2. So accordingly the name plate of the PT was checked and found with the asked setting of 6.6KV/110 Volt. 3. The testing and commissioning team was inquired about the testing report for review of the results and fund with the results OK. 4. So the reason of failure could not be ascertained. 5. Then the PT primary and secondary resistance of the supplied PT was compared with the healthy PT. In this checking, the results of the supplied PT on both primary and secondary were found less than of the healthy PT. From the resistance measurement comparison the supplied CT was suspected of rating (6.6 KV / √3)/ (110 / √3) V in place of (6.6 KV /110 V).

6. The supplier was inquired and admitted regarding the supply of wrong PT of rating (6.6 KV / √3)/ (110 / √3) V in place of (6.6 KV /110 V) with name plate of (6.6 KV /110 V).
(isolator- 89A) shall be used for the extension of PT supply to the protection and metering scheme, similarly for BUS-2 supply. ( refer the SLD of the BUS arrangement as fig-A)
Analysis : Both the ratio of the wrong supplied PT and existing PT are same (6.6 KV / √3)/ (110 / √3) = 60 and (6.6 KV /110 V = 60). So during ratio check of the wrong PT by the testing team, the problem could not be confirmed. More over the name plate as fixed was of 6.6 KV /110 V for which the PT was put into the 89 B circuit.
4. On this day as bus-1 was under SHUT DOWN, all the bus isolator (89A) was kept in OPEN condition. But BUS-1 PT isolator was not kept open, thinking of no supply on BUS-1.
But failure of the PT was resulting due to supply of 6.6KV to the winding designed with 6.6 KV /√3, which is √3 time less.

NOTE : To avoid such problem, while testing the PT, the resistance of the same has to be compared with the existing healthy PT in the system. 2.2. Blowing out of PT fuses: - 220/132 KV Grid S/S operating with BUS arrangement of 2 Bus and Transfer scheme, was causing blowing out of fuses during BUS short down condition. Observation : 1. On the day of BUS shut down, only one BUS ( BUS-1 ) was taken shut down and BUS -2 was in live condition and catering load to the system.
5. The blowing out of the fuses of this
BUS-1 PT was resulting during this shut down. Analysis: - Here individual line does not have its own PT/ CVT for the secondary circuit extension. So secondary PT supply was getting extended to the common circuit of protection and metering scheme. So in this condition the BUS PT was getting extended to 89A
89B
Bus-1 PT extensio n
2. In this grid sub-station, the PT supply to the Protection and metering scheme was getting fed from the BUS PT by the use of selection relay being energized from corresponding BUS isolator. 3. When BUS-1 used for the extension of supply, corresponding isolator

the schemes from BUS-2 PT from the selection isolator B being in closing condition. All BUS-1 isolators were in open condition (89A isolators), but due to problem in the secondary auxiliary switch that used for the status of the isolators, the contacts were in CLOSED condition in place of OPEN. So in the ||www.electricalmirror.in||
secondary side, 110 Volt supply was getting extended to this BUS-1 PT as because of BUS-2 PT was in charged condition (Refer Fig-B). In this situation BUS-2 was in charged condition. So 110 Volt supply was getting available from 220KV supply being stepped down by the BUS-2 PT. Now due to wrong in the secondary auxiliary switch problem, this 110 volt was also getting available on the secondary side of BUS-1 PT for which 220 KV on the primary side was reflecting momentary. The burden of the PT as not sufficient, so to meet the required rating, the current drawal being above as that of the rating results the blowing of the fuses. More over this kind of situation may also cause electrocution to the working personnel during working on the dead bus and sudden availability of back feed voltage on the bus. NOTE : - So it is always advised to open the BUS-PT isolator for the BUS taken under shut down to avoid any possibility of back feed voltage in the system. 2.3 Case of Abnormal reading of Energy meter: - For a 33/11 KV Sub-Station, the metering arrangement was done as per the BUS section available in the system. But it was observed with abnormal reading of one section side of the energy meter. Observation: - The detail arrangement of CT and PT supply to the energy meter for each section of 11 KV side were checked. This sub-station has two sections of 11 KV systems. One section was fed from an individual 33/11 KV TFR-1 and other section was from another 33/11 KV TFR-2. The PT supply was getting extended from individual 11 KV section. On inquiry with the grid personnel, it was reported that the PT supply circuit for the section-2 had been extended from PT -1, due to the failure of the PT-2 in the system. During these days of abnormal report on the readings of energy meter on section-2, the systems had been provided with transformers operating with different taps. So the actual 11 KV
||www.electricalmirror.in||
terminal voltage on each section were different to each other. Analysis:- The reading of energy meter depends upon the availability of CT and PT supply from the corresponding BUS as per the magnitude and phase angle between the CT and PT phasors . But in this condition, the BUS-2 PT was not available in the system and secondary PT supply was getting extended from available BUS-1 PT supply. More over the section 11 KV supply voltage was different due to the operation of transformers at different taps. 11 KV sec-1

2. Then the Line-1 was taken shut down and found with balance current on all the phases in LINE-2. 3. So it was suspected on the isolator/ breaker limb on this line-1 regarding the contact problem. Actions taken: 1. The contact resistance of isolators were checked and all found with the range of 200-250 micro ohm. 2. The contact resistance of all the limbs of the breaker was checked and found with normal for Y and B phase limb, but value for R phase was obtained with approximately of 50 Ohm. 3. So from the reading it was suspected on the travel and final position of the male and female contact during CLOSE condition.

So for the calculation of energy meter reading for section-2, the current of the section was getting from CT, but voltage was getting from the voltage availability of the Section-1. So the angle comparison between current and voltage did not become as per the actual value, for which the reading of the energy meter was coming abnormal. Rectification: After replacement of original PT and availing the corresponding voltage, the reading becomes normal. 2.4. Case of un-balance current reading on R phase:- The DC ( Double Circuit) line that connected between two stations was observed with unbalance current on R phase.
4. So this limb was replaced by a new one and then on wards, the current flow becomes normal. Analysis: 1. Because of problem in the contact of R phase limb, the current flow was becoming less due to more resistance on this phase. But the unbalance current in the secondary of protection circuit was also not resulting tripping of the relay, because of the use of directional Earth fault relay. This relay demands the un-balance of both current and voltage with angle of operation to the directionality feature. In this situation, though the current was becoming un-balance, but the voltage was getting maintained balance in the system. So the relay was not operating on E/F feature. Line-1

on the phase of healthy line, as it was resulting in this case for R phase. 3. This nature of un-balance was showing for the condition, if both lines remain in the circuit. But for the outage of the problematic line, the current flow becomes normal on all the phases of the healthy line. 2.4 Case of burning of Auxiliary Contact: This was observed with burning of Auxiliary contact of 33KV breaker circuit for every CLOSE Command. Observations: 1. With the existing NC contact of the breaker, when the breaker was closed, the sudden change over of the contact to NO was resulting burning anf failure of the contacts. 2. So thinking of current during changeover might be more, other NC contacts were used in parallel for the diversion of current. But this time it was also found burning of all contacts that used in the closing circuit. 3. So, the total auxiliary contact switch was replaced by another good spare switch. 4. Again the attempt was taken and similar observation was found. Actions taken : 1. Now three number of NC contacts were used in series for the CLOSING circuit. Then the operation was taken and this time no such abnormality was observed and breaker closed successfully without burning of contacts. 2. The resistance of the CLOSING coil was measured and found with the value of 90 Ohm and closing time being 85mSec. 3. The operation time of the auxiliary contact was measured and found with 60-65mSec. Analysis : When the closing command was attempted keeping one NC in the circuit, the availability of required voltage across it during changeover was of approximately of 220 Volt Dc (operating voltage of the closing Coil). Moreover the changeover time is of 58 ELECTRICAL MIR ROR

approximately (85mSec+65mSec = 150 mSec). So up to such time this voltage could be available with flow of operating current of (220/ 90= 2.44Amp). So the contact was failing.
3. So separate contacts were planned for individual purpose of BULB and SEMAPHORE purpose. 4. But spare cores were not available in the existing laid cable from breaker cubicle to control room.

The future of Maintenance is Here! How Advances in Technology are Changing the Maintenance Landscape
W
hile maintenance practices are part & parcel of every industry and have evolved rapidly over the last few years, recent advances in technology are helping take the next giant leap. However, quality of maintenance practices is gaining attention given the focus on operational efficiencies and cost. Let us understand this.
What are the guiding principle of Preventive & Predictive Maintenance (PPM)? PPM is the regular and systematic application of engineering knowledge and maintenance attention to equipment and facilities. This ensure their proper functionality and reduce their rate of deterioration. In addition to dedicated engineering, PPM encompasses regular examination, inspection, lubrication, testing and adjustments of equipment without prior knowledge of equipment failure. PPM also provides the framework for all planned maintenance activity, including the generation of planned work orders to correct potential problems identified by inspection. The result is a proactive (rather than a reactive) environment, optimizing equipment performance and life.
What can PPM deliver Properly developed PPM programs are engineered efforts, which optimize the relationship between equipment ownership and operating profits by balancing cost of maintenance with cost of equipment failure, and associated production losses.
Equipment ownership cost is a function of three factors 60 ELECTRICAL MIR ROR
|| MARCH 2016
• Purchase price, • Equipment life and • Maintenance cost... where
Maintenance Cost = Material and labor cost required to repair the item + Cost of preventive maintenance to avoid repairs + Cost of lost production while the unit is out of service for repairs. Total maintenance cost is the sum of material and labor cost required to repair the item, the cost of preventive maintenance to avoid repairs, plus the cost of lost production while the unit is out of service for repairs. PPM includes actions which extend the life of equipment and avoid unnecessary failures by substituting selective programmed effort for “fix it when it fails” maintenance.
What actions can extend the life of equipment: These include - lubrication, cleaning, adjusting and the replacement of minor components like drive belts, gaskets, filters, etc. Actions that avoid unnecessary failure include timely, consistent equipment inspection and the aggressive use of nondestructive testing techniques such as vibration analysis, infrared testing, oil analysis and other techniques. Predictive maintenance is the complement of preventive maintenance. Through the utilization of various nondestructive testing and measuring techniques,
Mr. Vikram Bhansali
predictive maintenance determines equipment status before a breakdown occurs. With predictive devices currently available, it is incumbent upon maintenance organizations to include the process of predictive maintenance in their maintenance programs.
PPM Is Comprised Of 1. Proper organization 2. Proper operation of equipment 3. The proper lubricants, in the right quantities, in the right location, at the proper time 4. Predicting wear and deterioration by regularly checking, measuring and adjusting A. Regular inspection to identify small repairs before they become major repairs B. Predictive techniques to replace components just before they fail i) Vibration monitoring and analysis ii) Infrared inspection iii) Sound detection iv) Lubrication and oil sampling. v) Etc.

It records and times 3-axis vibrations with peaks to provide a history of shock and vibration conditions. It also records the time when free-fall happens. It measures and computes real-time spectral data using an FFT (Fast Fourier Transform) from 0 to 60 Hz. B. Infra Red Inspection : Infra Red inspection is non-intrusive way to check for any variation in temperatures which helps in precision detection of electrical & mechanical faults. While there are many available in the market, CEM We provides both thermal imagers and infra red thermometers for measuring temperature. The unique feature of these is the ability to is can be then recorded and stored directly on the PC, thereby making them highly convenient for use.
The thermal imagers are the ones that is most widely used in PPM. Thermal imagers allow users to measure temperature in applications where conventional sensors cannot be employed. Specifically, in cases dealing with moving objects (i.e., rollers, moving machinery, or a conveyor belt), or where non-contact measurements are required because of contamination or hazardous reasons (such as high voltage), where distances are too great, or where the temperatures to be measured are too high for thermocouples or other contact sensors. The thermal imagers provide an image, which shows the Once again, allow a technician to be seen with the unaided 62 ELECTRICAL MIR ROR

Lubrication and oil sampling Borescoping : Borescoping is like having an eye at the end of a cable. NDT is being able to inspect something without changing the actual structure of what you’re inspecting. You have something that’s small enough to get inside small access areas like a screw hole that brings you inside of a frame. We have technology like articulation so you can navigate a cable through some pretty difficult small areas. With every type of instrument there is for NDT, nothing beats actually being able to see it. Whether it’s a video with a camera, or going more old school with a fiberscope, you see what you need to see. You can get a lot of tools to get you different readings, but in the end nothing beats having somebody looking at it. Video borescopes.
