A warm thank you for admiring our magazine and looking forward to it with such vigor and enthusiasm. You are truly wonderful audiences. It gives us great pleasure to present to you our ‘Golden Anniversary Edition.” This edition boasts of a range of varied articles lined up just for your reading pleasure. Electrical Mirror was founded in 2011 with the goal of providing insight into the electrical and power industries. As Electrical Mirror celebrates its eleventh anniversary, a look back at the publication's main milestones illustrates the dedication with which it has chronicled and analysed every important event in India's electrical and power industries for its readers across the country. India's electrical industry, which includes power, is among the most critical components of infrastructure, crucial for the economic growth and welfare of nations. The existence and development of an adequate power infrastructure is essential for the sustained growth of the Indian economy. India's power sector is one of the most diversified in the world. Sources of power generation range from conventional sources such as coal, lignite, natural gas, oil, hydro, and nuclear power to viable non-conventional sources such as wind, solar, and agricultural and domestic waste. Electricity demand in the country has increased rapidly and is expected to rise further in the years to come. In order to meet the increasing demand for electricity in the country, a massive addition to the installed generating capacity is required. India was ranked fourth in wind power, fifth in solar power and fourth in renewable power installed capacity as of 2020. India is the only country among the G20 nations that is on track to achieve the targets under the Paris Agreement. We hope that the valuable content contained in our magazine will assist you in gaining an understanding of themes related to the power and electrical business, such as wires and cables, T&M instruments, transmission and distribution, lightning protection, electric vehicles, earthing, gensets, power factor correction, renewable energy, among others.

New study from AEEE lays out a ‘Roadmap for Demand Flexibility in India’ and effective low carbon strategies for DISCOMs to manage peak demand

Press Release

DISCOMs need to carve out the ideal customer centric Demand Response (DR) strategy comprising a portfolio of customizable options that can be customized to suit the needs of different consumer segments.

Alliance for an Energy-Efficient Economy (AEEE), one of the leading organizations in India creating awareness about energy efficiency as a resource, today released a report titled “Roadmap for Demand Flexibility in India” in collaboration with AutoGrid. The report highlights the wide range of possibilities that Demand Response (DR) offers that can effectively help electricity distribution companies (DISCOMs) in India handle their increasing future electricity demand while still operating reliably towards a greener grid. It further states that DISCOMs should carve out the ideal consumer centric DR strategy, comprising a portfolio of customizable options. Speaking during the report launch, Dr. Satish Kumar, President, and Executive Director, AEEE, said, “Given the increasing electricity demand in India, it is imperative that Demand Response is brought to the mainstream by the regulators, system operators and DISCOMs to effectively manage demand. Today, as the power generation is getting greener, yet more intermittent and had to predict, it is absolutely critical to focus on flexible demand as a balancing resource and need to be included in Integrated Resource Planning process and by enabling performance based regulations. For this to happen at scale, consumers should be allowed to participate in the energy and ancillary markets. Time is right to leverage advanced metering infrastructure and other innovative technologies to roll out well-designed DR programmes. Enriched with AutoGrid’s global expertise and pioneering experience, this report will serve as a roadmap and guide for key actors responsible for reliable and cost effective operation in a low carbon grid.” According to the report, • Scalable DR programmes can become successful if they are designed to create win-win situations for both consumers and DISCOMs. • Leveraging the energy data collected by smart meters to segment the consumers and identify potential target consumers is a useful tactic. • Initial interventions can be facilitated by the use of Behavioural DR measures which can be further scaled to include more advanced automation options like

Flexible DR. “We are excited to partner with AEEE to lay out a clear roadmap to manage the growing peak demand related problems and dependence on coal or other fossil based sources”, says Vish Ganti, VP & General Manager of AutoGrid. “Tapping into the power of collective human action, DISCOMS can create a strong customer value proposition for smart metering investments, Virtual Power Plants and incentivize good behavioral actions” he added. Over the past 5 years, a 50% increase in households with ACs has added significant new cooling load to already increasing peak demand. This growth however can be turned into an effective resource by DISCOMs though intelligent load control with built in DR and Wi-Fi enabled plug-ins as part of a Virtual Power Plant program. Demand flexibility through effective DR programmes provide the pathway to consumer participation in mechanisms for grid support services. Today, behavioural DR programmes constitute the bulk of that potential and are easy to tap into because of the relatively lower running costs. Subsequently, with the rise of controllable loads and smart appliances, advanced Auto-DR, called Flexible DR (Flex-DR), should be explored. Flexible demand can go a long way in ensuring the supply-demand equilibrium in grid operation with variable supply and increasing demand. Additionally, well designed, strategic DR initiatives will lead to higher energy efficiency directly contributing to consumer savings and meeting the target of net zero emissions set during the COP26 summit. As per the report, the Bureau of Energy Efficiency has emphasized the crucial role of energy efficiency (EE) in India’s energy transition, and it is estimated that emission reduction due to EE equates to 50% of India’s total emission reduction targets. Nevertheless, to sustain operations in the future and achieve the goal of affordable and reliable energy supply, DISCOMs need to think beyond EE programs and take a proactive role in engaging with consumers. In this regard, DR presents a leapfrog opportunity for DISCOMs to better adapt to the realities of a cleaner grid and high electrification of demand. EM ||www.electricalmirror.net||

The Government of India has announced an infrastructure investment of INR 7.5 lakh crore this year in various sectors of the economy, which is further supported by an uptake in private CAPEX in the industry as well as supported by the construction and the real estate sector, in particular, the Prime Minister Awas Yojana.” Meanwhile, Mr. Shreegopal Kabra emphasised on the quality of wires that should be used. “We need to focus on quality and safety,” he said, adding, “Of all the fire accidents, about 70-80 percent are due to electrical, and out of these electrical fire accidents, about 70-80 percent are due to faulty wires and cables.” Mr. Vijay Karia also highlighted the safety and sustainability issues and requirements in the wire and cable industry. “I think the safety of the industry starts from the way we conduct our business. The concept of ‘sustainability’ is not just about the environment, but it means that the company or the industry is able to sustain itself. Sustainability does not imply that one just becomes a zero emission industry or a zero emission company. The idea of sustainability starts when the business is sustainable in all respects.” Mr. Anurag Pandey appreciated the government’s focus on the infrastructure, auto sector, and the rural economy which is boosting the growth of the steel wire sector, adding, “The wire industry is the closest to the customers, in the steel value chain; we are very close to the end-consumers, whether it is with regard to the fencing wires, or tyres.

Underground Power Cables: Why Underground Cables Are A Better Deep-Rooted Choice For Utilities? Introduction

substations, load centers, etc.

Electric power is transmitted and disturbed either by overhead system or by underground cables. A cable is an insulated conductor and is used for underground transmission and distribution of electricity. Underground cables are generally used in densely populated areas such as cities, metros, where there is high density of automobiles. Underground cables are also preferred in industries, sub-stations, railways and road crossings, servicing of residential installations and other similar locations. This cable structure help in ensuring uninterrupted power supply, which are uncommon in the overhead wiring system.

Most modern communities today utilize underground electrical cables to distribute electricity instead of hideous overhead cable and utility poles.

What is Underground Power Cable? The power transmission achieved through cables that are laid underground are called Underground Powe cables. The primary function of the an underground power cable is to transfer power between locations including generation sources,

||www.electricalmirror.net||

Underground cable lines first appeared back in 1890, when the first successful installation was introduced by Vincent de Ferranti using his famous 10, 000 - volt concentric cable in the UK. Since then, underground power transmission has evolved dramatically. The first underground power cables to be used in India were probably at Shivanasamudram hydel power station in the erstwhile Mysore sub-station in around 1902 but there is no such official record, it is anticipated that underground cables had to be used to bring the electricity from the generators to the open outside. This was the Asia's first hydro-electric generating station, commissioned in 1902. Although, it is on record that in 1920, Shimla installed underground cables fed from the sub-station that still stands

on the ridge, and has an official heritage status. Some of the cables connecting to it are still in use after 90 years. Traditionally, underground cables are used in cities where overhead lines are not feasible; in areas wher an overhead line may risk lives. In terms of safety, there is no disturbance at the ground surface when a short circuit occurs or a very high amount energy is released, because the soil contains the fault.

Wire & Cables

The soil also protects against third party damage as long as proper authorization procedures are followed before digging, especially in urban areas. Additionally, th current generation of underground systems require less maintenance, and reclamation is only required every 40 - 50 years, which is the specified lifespan of a transmission line.

While choosing between overhead power lines and underground cables, it is important to know the pros and cons so you can make an educated and wise decision. Between these two cables, overhead electrical cables are more common for good reasons. Although some may consider them as monstrosity specially in urban areas, in terms of cost they are three to four times cheaper than underground cables.

Extra Safeguard Underground cabling may require additional charges as the wires will go the longer route between the two points unlike the overhead wires where the wires will just hang above houses and buildings. Also, underground cabling requires additional insulation and cooling because the wires can overheat otherwise.

The reason for it being quite expensive is because when The underground cabling system consists of various components burying the wires in rocky areas for example, you need to like temperature & condition monitoring systems, earthing clear the location with huge machines and fill it with soil to and bonding systems, cable joints, junction boxes, above the avoid damage to the cable and apart from this, you need to install cable jointing structure every 500 meters as well ground termination points, etc. as extra insulation.

Structure of the Underground Power Cable

As we have already stated, electrical wires emit heat so they have to be kept away from drainage, marshes, and bogs.

Image of Structure of the Underground Power Cable

Types of Underground Power Cables The types of the underground power cables based on its voltage handling capacity, insulation material and core diameter, these cables are classified into five different types as: • Low Tension Cables (LT) • High Tension Cables (HT) • Super Tension Cables (ST) • Extra High Tension Cables (EHT) • Extra Super Voltage Cables (EST)

We need to take care of the deeply rooted plants and buildings with deep foundations in order to avoid the destruction. It's also a known fact that there is an effect to the soil of the plastic sheathing on the cable wires that have decomposed into the soil. We cannot say that it's not achievable as a country like Singapore has a 100 percent underground cable system.

Extra Hazardous In contrast, overhead cables are easy to maintain but the danger is associated with it. Although visual discordance can be a huge challenge for urban areas. The wires are also vulnerable to low-flying crafts, birds, external obstructions like extreme weather conditions which can cause shrinkage and stretching on the cables. The damage of the pole due to unforeseen conditions like a truck smashing into the pole can create undue stress to the transmission of the lines. Government has advised to employ professional electrical reticulation services in order to minimise the risk. The companies specialising in wires and cables electrification networks have ||www.electricalmirror.net||

also advised to install maximum safety mechanisms to ensure that the electric system is insulated from unnecessary risks.

A Huge Shift to Underground System Underground cables are usually used in such locations where overhead line rights of way are not available, in areas where local or state regulations override economic considerations, near airports and other locations where an overhead line may endanger lives, and in picturesque areas where appearance is an important consideration. Infrastructure is one of the considered shaping forces for urban and regional development as underground wiring framework in developed areas may offer best acceptable ways to encourage and support more sustainable growth in future sustainability of cities and towns.

undergoing redevelopment. The high court made it clear that non-compliance of the order will invite contempt action against the agencies. A bench of justices Vipin Sanghi and Rekha Palli said," We direct all the agencies including North MCD, MTNL, and BSES, etc to ensure compliance so that all hanging wires and cables are removed. All services providers shall ensure compliance failing which we will be compelled to initiate contempt action." The government said in a statement that about 2,264 km of bare conductor network will be converted into an insulated network by the three distribution companies - Tata Power Delhi Distribution Limited, BSES Yamuna Power Limited and BSES Rajdhani Power Limited in Delhi.

The chief Minister of Delhi, Arvind Kejriwal has also stated Because of the associated dangers to overhead cables framework, that the government was working on shifting all overhead government is seeing the advantages of underground cables electrical wires into underground cables framework. framework The official data shows that out of a total of 2,264 km of In 2021, the Delhi government approved a policy to convert electric wires, TPDDL will convert 1,270km into an insulated bare electricity lines into insulated conductors for protection network, BYPL 29 km and BRPL 965 km.

insulated covered conductors (cables) will be a cost effective solution compared to shifting them completely underground, while in areas with rocks underneath, insulation must be needed, they added to their statement.

Advantages Of Using Underground Power Cable

In East and Central Delhi, BYPL has 2, 662 km of cables at the 11 kB level. Of this, 2,636 km or 99% is underground and only 26 km or one % is overhead uninsulated, they said. In TPDDL, area of North and North West Delhi, around 65% of the cables are underground at the 11 kV level. Around 1,270 km overhead is uninsulated, the sources said. Around Rs 2, 400 crore is estimated to be required for the conversion of the entire existing high tension overhead network to Underground. On the other hand, it is estimated to cost around Rs 700 crore for insulating them. The Delhi government has provided Rs 25 crore to the power department in the financial year 2021-22 for the project under the 'Jagmagaati Delhi" programme. "There are two philosophies for conversion of overhead bare conductors (wires) to enhance safety and aesthetics," said power sector experts. "The first option is overhead to underground and the second option is insulating bare conductors (wires). Between the two, the first one is the preferred option," they said. Although, in a practical outline, a combination of the two works the best. In rural areas with appropriate clearance, ||www.electricalmirror.net||

Reliability

• At a time where system reliability is top of the mind for almost all the utilities, underground transmission is a dependable solution in the market. • Underground lines pull through in the face of extreme conditions including: • Atmospheric conditions like hurricanes, typhoons, tornadoes, wind and ice storms • Human activities like vandalism and terrorism • Natural calamities including landslides, floods, and in some cases even tectonic activity

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

networks are overhead and all the new upcoming networks are underground. Just 965 km or 14% is over-head wire and uninsulated.

• Underground transmission is picking up steam for good reasons. • Affordable and Simplified Sedentary Process in Urban Areas • Overhead wire lines require land acquisition in the right of way for support structures like poles, towers and conductors and land acquisition comes with inherent challenges like removal of structures for electrical clearances in the line's path, and a often a large price tag. • Enter underground transmission lines can be installed in dedicated public passage with dense population, and don't require right of way acquisition. Underground lines are often more economical than requiring land acquisition for support structures in overhead wiring. • Negligible Impact to the Environment • Underground transmission preserves natural resources and land value. The lines are out of the sight, which clears one of the main concerns for overhead linesaesthetic impact. While aesthetic impact is not the only concern, it also tops the list of long-term impacts that can be mitigated. • The International Council on Large Electrical Systems, or (CIGRE) compared the impacts of overhead lines and underground cable lines in terms of impacts on the environment in its technical brochure 110.

Provides Safety

• Underground cables are electrically shielded and out of the way. Whereas in overhead wiring cable accessories like terminations are exposed at poles, terminal towers and substations, underground transmission constitutes less risk: || JULY 2022 ||

• No crucifixion hazard for people and wildlife • No collision or quagmire hazads for small planes or helicopters • No risk of like exposure from traffic collisions • No risk of fire to people, wildlife, nature or homes from curving lines during windy conditions • Transmission loss is negligble in underground wiring. • Completely eliminates electrical and magnetic field above the ground level which otherwise would pose a threat to health concerns

Wire & Cables

Disadvantages of Underground Power Cables

• Underground wiring is convenient and aesthetically pleasing, but when problems occur you have to enlist numerous services and electrical experts to pinpoint the break and advise you on the best methods of repair the damage • Laying of cables requires digging which might be difficult in congested areas • Cost of maintenance is high as we need huge machines and electrical professionals to maintain and repair the damage • Modification to exciting cable network is arduous as it requires completely new excavation • Susceptible to damage due to underground water and moisture in the soil • Heat depletion is less effective • As underground cables are more thicker than overhead cables, the cost involved in the manufacturing is high

Market Scope The rise in urbanization and increase in infrastructure are major factors driving the market growth. These factors have impacted the power and energy demand in commercial, industrial, and residential sectors. Implementation of smart grid technology has met the rise in need for grid interconnections, this resulting in surge in investments in the new underground and submarine cables. However, intial heavy cost is the only factor which limits the growth of the underground cable market.

Impact of Pandemic in the Market of Underground Power Cable

Italy, UK, and China which are negatively affected by the spread of the coronavirus, thereby declining the demand for underground cable products. Further, potential impact of the pandemic is currently vague and financial recovery of companies is totally based on its cash reserves. Underground cable market are expected to focus on protecting their workforce, operations, and supply chains to respond towards immediate crises.

Market Trends With the growth of smart grid technologies and the increase in renewable energy capacity, specialized cables are being designed. For instance, medium voltage smart cables which integrate optical fiber cable with power cables, are preferred for smart grid applications. Number of government initiatives and programmes have been undertaken such as Deendayal Upadhyay Gram Jyoti Yojana (DDUGJU), the Integrated Power Development Scheme (IPDS) and th recently launched Sahaj Bijli Har Ghar Yojana (Saubhagya). All these schemes have created a market for cables and conductors in the country. Business expansion strategies also assist in enhancing the geographical footprint of the complete and help in gaining significant market share for underground cables. Key companies take various strategies initiatives, including partnerships, merges & acquisitions, collaborations and new product launches give a huge scope to imerge in the market. Challenges for underground cables include the lifespan of a transmission line and high cost as well as the lack of public acceptance. However, underground cables not only protect against balckouts during peak and load hours and severe weather events, but also from an environmental point of view provide massive electrification, which is the best way to decarbonize our energy system.

An overview of Testing and Measuring Equipment Global Market! Testing and measuring is one of those terms that is being used by small devices to big devices but what does it truly mean? In this article we will look at what it means and how it can make your brand a big hit and help you in building goodwill in the market. Before leaping into the subject of testing and measuring equipment, know the basic information of why we need testing and measuring equipment. In fact, with the basic understanding of the equipment of testing and measuring we can easily perform testing and measure the efficiency of our devices. Our daily life is incomplete without various electronic and electrical devices such as laptops, mobile phones, and other gadgets, etc. From mobile phones to huge machines used in industries are tested through several levels to ensure perfect working tests. The instruments used to test various parameters defining the flawless performance of an application are commonly termed as test and

||www.electricalmirror.net||

measurement equipment. Test and measurement equipment can be categorized into three sections: • Devices that are used for measuring basic system parameters like voltage, current and resistance • Devices that are used for testing stimulus signals • Devices that measures the response to these signals Voltmeter, Ammeter, Ohmmeter and Multimeters are the most common devices in the first category. Voltmeter which is also known as voltage meter is an instrument that measures the voltage or potential difference among two points of an electrical circuit. A voltmeter measures the voltages usually ciphered in volts, millivolts (0.001 volt), or kilovolts (1,000 volts). In order to measure a device's voltage, a voltmeter is connected in parallel to a device. A voltmeter also has a high internal resistance so it can be used in measuring the potential difference between the two points of the circuit.

|||| JULY JuLY2022 2022 ||||

ELECTRICAL MIR ROR

There are other types of voltmeters based on their construction.

Voltmeter Symbol (Image)

Types of Voltmeter

T & M Instruments

Analogue or Analog Voltmeter

An analogue voltmeter is used mainly for measuring the AC voltage. The reading of the device is displayed with the help of a pointer that is fixed on the calibrated scale. A galvanometer (current meter) that is sensitive and is a part of the high resistance series that makes a basic analogue voltmeter. The meter should have a high internal resistance otherwise the circuit operation during the test would be interrupted by drawing current significantly. The voltage range displayed by the meter is determined by the galvanometer sensitivity and the series resistance value. Digital Voltmeter

Digital voltmeter is the most used and versatile voltage measurement instrument among all the voltmeters that can be used to gauge current, voltage as well as resistance.However at first glance, digital multimeters may look very complicated with their displays, dials, and port panels, yet when you become familiar with its workings it becomes very handy. Digital multimeters serve the purpose of testing and measuring with highest accuracy, reliability and efficiency. It is a very constructive device to measure the perfect temperature. A digital voltmeter measures an unknown input voltage by converting the voltage to a digital value and then displays the voltage in numeric form. What makes digital multimeters the preferred option over analog metres?

Here is the basic reason of it: While analog multimeters indicate the value with a needle over a scale, digital multimeters have a LED or LCD display, which can display output as a digital numerical feed even up to decimal points. This makes it very specific, accurate and readable. Apart from it the best part about digital multimeters is that they can be adjusted whenever required to measure in ohm, ampere and volt. 44

The devices that are used for testing stimulus signals include power supplies, signal generators, and pulse generators. As the names suggest, power supplies are devices that provide electric power, signal generators generate electrical signals and pulse generators generate rectangular pulses. Devices like oscilloscope measure system response to the input signals and It is probably the most commonly used electronic instrument in the field of electronics circuit design, testing and troubleshooting. When you first heard the word 'Oscilloscope' many may be wondering what the heck it is and how do you pronounce it. As a matter of fact, this electronic testing and measuring instrument is used in many diverse industries like medicine and science, engineering, automotive and telecommunications, etc. It may sound like something that is only used in hospitals but it can be used in a variety of situations, as it is a device that allows the observation of constantly varying signal voltages. It can be used from a car's ignition system to watch a heartbeat as an electrocardiogram. The Oscilloscope has been an anchor instrument during the past years for the television technician all the way to an aerospace engineer. Oscilloscope is an instrument that shows the graphic illustration of electrical signals and this device is powerful for observing electrical signals. A device that provides digital illustration of electrical signals is called digital Oscilloscope. The first few decades of Oscilloscope designs were based on analog amplifier circuits that brought the amplitude of the signal to be viewed to the level sufficient to drive the deflection plates of the cathode Ray tube in the Oscilloscope.

There are two types of Oscilloscopes: Analog oscilloscope v/s Digital oscilloscope • The Analog oscilloscope diversified voltages while the digital oscilloscope sends the signal and the ADC converter ||www.electricalmirror.net||

Protection of transmission line towers during landslides - A case study Abstract North East Transmission Company (NETC) is entrusted with construction and maintenance of it’s 662.8 Km, 400 kV Double Circuit transmission line in the difficult hilly & dense forest terrain in the states of Tripura, Meghalaya and Assam in the North Eastern Region (NER) of India. The terrain consists of various types of soils viz. laterite, alluvial, loamy, red soil etc. and is prone to sinking and landslides due to steep gradient and soil characteristics accompanied with heavy rains in NER. The transmission line route traverses through areas of high rainfall, wind zones of V & VI and high Isokeraunic level. NETC is regularly facing the soil erosion /land slide issue in various tower locations of Pallatana -Silchar Line section. The deforestation due to development and various construction works coupled with incessant heavy rains of NER are some of the reasons behind such landslides. This paper strives to describe various types of challenges being faced by NETC in operation and maintenance of the line with respect to landslides, sinking of hills, soil erosion etc. and the mitigation measures adopted by NETC like providing bamboo palisading, retaining wall, maintaining the natural

INTRODUCTION- NETC’s Transmission Line NETC’s transmission line is evacuating almost one third of the power demand of the North Eastern Region of India along with exporting power to a neighboring country. This 400 kV transmission line corridor has been envisaged to evacuate power from ONGC Tripura Power Company’s (OTPC) Palatana Gas Based Combined Cycle Power Project of 2x 363.3 MW in Tripura state. NETC has constructed 662.8 km of 400 kV Palatana- SilcharBongaigaon Double circuit line as detailed below: i) 400 kV Pallatana- Silchar D/c line (247. 39 km) ii) 400 kV (First circuit of D/C) Silchar- Byrnihat line (214.41 km) iii) 400 kV (Second circuit of D/C) Silchar- Azara line (256.41 km)

iv) 400 kV (First circuit of D/C) Azara - Bongaigaon line (159 km) v) 400 kV (Second circuit of D/C) Byrnihat-Bongaigaon line (201 km) Challenges The task of operating and maintaining the transmission line with 100% availability is a prime concern of the company. NETC is facing following major challenges in this regard: i) Vulnerability of line due to exposure of tower foundations because of landslides & excessive rainfall. The transmission line is traversing through the states ofAssam and Meghalaya having highest rainfall to the tune of about 3 to 5 times the average rainfall in India. The average annual rainfall in India is 300- 650 millimetres,where as in NER the Average rainfall is 2500-3000mm. ii) Submergence of towers in low lying areas iii) Tower endangerment during high wind & cyclones and changing course of rivers iv) Outages due to severe lightning in hilly terrains with high soil resistivity v) Transient fault & safety threat due to fast growth of vegetation and bamboo trees on hillsides due to the climatic condition of NER and local tradition of subsequent burning of these vegetations under transmission lines vi) Impact on the life of transmission line and outages due to rapid industrial pollution. In addition to the above mentioned environmental & climatic challenges as well as inhospitable terrain, there are several local & social challenges related to insurgency, theft, Right of Way etc. The Landslides in Pallatana-Silchar 400 kV line section in the state of Tripura The NETC inter-state transmission line is passing through dense forest and hillocks and small hilltops in Tripura where the rain induced landslide is a regular phenomenon especially during the onset of monsoon every year and it puts to risk the transmission line towers may result in outage of the transmission line. In the years 2016, 2018 and 2020, the state of Tripura experienced unprecedented heavy monsoon with incessant ELECTRICAL MIR ROR

|| JULY 2022 ||

rains in the month of June. The intensity of rain was so severe that within a time span of 7–10 days, the free flowing rain water caused very heavy landslides in the entire hilly stretch of the State resulting in number of road blockades in the Inter-State National Highway including some arterial roads. The road cutting work being carried out in small hilltops also contributed to the landslides and instability of the hill slopes. During the year 2016, the Pallatana-Silchar line which is passing through 73 km of Hilly forest in the state of Tripura region experienced frequent earthquakes of High intensity and heavy monsoon with incessant rains which are not a normal phenomenon. During earthquake, the horizontal seismic forces had created voids in a soil strata due to which water seepage caused sinking of Land mass in this region. Due to above landslide in the state of Tripura, 25 numbers of tower locations of Pallatana-Silchar section of the transmission line were badly affected and 14 numbers of tower locations became vulnerable. Landslides are caused by disturbances in the natural stability of hill slopes and generally occur due to heavy rains, earthquakes, or local factors like deforestation, shifting cultivation or quarrying activities. The climate change impact also affects the weather pattern and landslide phenomenon. Approach & Methodology: -Mitigations Measures adopted by NETC. This line being the high-capacity line for evacuation of power from a 726.6 MW Generation Plant, any break down like tower collapse etc. would have caused outage of the Plant resulting in severe power crisis in the North Eastern Region. This emphasized immediate temporary measures to protect these vulnerable towers for providing minimum protection followed by permanent protection. There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage. An expert committee of Site/Head office was constituted and committee visited all the locations.It observed that in most of the tower foundations were exposed.

||www.electricalmirror.net||

It recommended various measures to prevent the towers collapse. As an immediate measure, temporary protection was suggested followed by revetment protection as permanent solution. The slope protection study and survey conducted through survey expert to shift the 2 Nos tower locations and various Guying arrangement were provided to 400 kV Tower locations for the support. The proper drainage of water from the tower base ensured. The proper drainage of water from the tower base was also ensured. Temporary Protection: As an immediate temporary measure to protect these vulnerable towers, bamboo palisade in multi steps was provided along with empty cement bags filled with earth providing minimum protection. Sufficient plantation was also done in the eroded sides of the locations to retain the soil. Temporary protection work includes the shifting of material at tower locations, supply of cement bags filled with soils, erection of Bamboo Basket/ Palisading work. Bamboo anchors the soil with its spreading root system thus preventing landslides.Apart from this, bamboo is used as barrier against soil erosion and other environmental services such as protection of water sources though reforestation of watersheds. Bamboo is a fast growing plant and its wide network of roots and rhizomes is highly effective in keeping a check on soil erosion by holding/binding the soil firmly, thereby preventing soil loss from ravines.

How NGEPL’s has geared up to support the government’s missions? Despite suffering from supply chain constraints, increased shipping costs, and rising prices for key commodities, capacity installations remained at an all-time high due to rapid technology improvement and more focus by government in renewable energy. Wind and solar capacity additions of 13.8 GW in the first eight months of 2021 were up 28% over the same period in 2020. Many cities, states, and utilities set ambitious clean energy goals, increasing renewable portfolio standards and enacting energy storage procurement mandates.

Renewable energy growth is poised to accelerate in 2022, as concern for climate change and support for environmental, social, and governance (ESG) considerations grow and demand for cleaner energy sources from most market segments accelerates. This will be opening new avenues in the renewable energy growth story, as most of test equipment are aligned to test the equipment used for in green and renewable energy, I am sure we will contribute significantly in this initiative.

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 synchronization of practical observation to the theoretical concepts. The analysis of each incident being supported by actual observations had been described during the situation to add awareness amongst the operation, testing and commissioning engineers to know the cause of problems and be helpful for easy rectification of the problems. This can also help to develop economic schemes for the smooth running of the operation and control system in the Grid Sub-Station. 2.1. Recording of different Fault Current: For a DC (Double Circuit) Transmission Line, on a particular instance, both the lines on the same Tower tripped on multi-phase fault.

Observations

1. The fault recording results with following reading on the DP relay.

ELECTRICAL MIR ROR

|| JULY 2022 ||

2. Recording of Fault current on circuit-1 at one end a. Ia = 5.471 KA, Ib= 2.653KA, Ic= 13.75 KA with Fault Distance = 1.52 Km and tripping on Zone-1 with multi-phase 3. Recording of Fault current on circuit-2 a. Ia = 6.481 KA, Ib= 13.71, Ic= 2.62 KA with Fault Distance = 1.53 Km and tripping on Zone-1 with multiphase 4. The current pattern was different for each of the circuit and current recording was also different on each phase at same location of fault. 5. Both the lines were trial charged and stood OK and then loaded also. 6. Both the lines were fed from grid sub-station, but connected to other end to other different station. 7. The remote end stations were also interconnected with other sources. So this network is of inter-connected system with different sources. ||www.electricalmirror.net||

8. Practically TWO different lines to different stations were connected by transmission line. For easier connection and proper transmission corridor, few towers were used of DC (Double circuit) type and then bi-furcated with SC (Single circuit system) for feeding to respective stations. 9. This incident had been resulted on one of the common connected DC tower. 10. On this tower, one side was with Porcelain DISC insulator and other side was with Porcelain LONG ROD insulator. 11. On the day of such incident, it was observed with heavy lightning at that locality.

Technical Analysis

||www.electricalmirror.net||

11. So pattern of air ionization may be different, which has been found in this case. 12. Because of such phenomenon, the current pattern on each phase was also different. 13. We can conclude here that the Lightning phenomenon is quite erratic and may exert any pattern of current in the system, due its peculiar discharge current.

Action Taken:

1. All the DISC insulators were replaced with Long Rod insulator. 2. The TFR (Tower Footing Resistance) was strengthen by putting extra Earthing pit at the fault location. 3. Moreover, the site was Rocky field. So special Earthing treatment was done.

Recommended Action:

Tower footing Resistance (TFR) on Transmission line should have to be enhanced to avoid the lightening effect on the line. 2.2. Failure of Live Tank CT: One of the 220 KV Live Tank CT failed with burning of Top Tank insulation and oozing of oil due to bursting of Top Tank side cover.

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

1. As mentioned above that two different lines with common tower have been disposed and then with SC tower for their respective station, so pattern of network length and corresponding electrical parameters like impedance, line length etc.. are different. 2. Moreover, the receiving end being other different station may have different Source impedance. 3. So, fault current recording at the particular fault location may not be same. As current contribution from the respective sources may not be same in this case. As explained in the fig 2.1 below. 4. But point of discussion regarding the pattern of fault current on each phase. Here A phase recording is approximately same for both the lines. But B and C phase fault current recording pattern is different. B phase current on circuit -1 is lesser value but B phase current recording on circuit is very high. Similarly, for the case of C Phase current recording is very high with respect to C phase on cuircuit-2. 5. This is the case heavy lightning at the fault location. Now due to higher Tower Footing Resistance (TFR), the Lightning current dissipation might have been suffered with delayed discharge, resulting potential rise on the fault location TOWER. 6. Because of higher voltage on the TOWER, the BACK Flash might have been occurred on all the six insulators from Tower to Line Conductors. This lightning effect usually dies down within milli-second. 7. But just after lightning effect, surrounding air medium being contented with ionized particles shall cause FRONT FLASH. 8. Now difference is there on the development BACK FLASH and its impact of resulting surrounding air medium of conducting. 9. This impact and its magnitude depends upon following factors.

a. Development of Voltage on the Tower due to delay discharge of Lightning current (L dI/dt). b. Path of discharge regarding its creepage distance and condition of the material used on its path. 10. In this case circuit-one was with DISC Porcelain insulators and circuit -2 has LONG ROD insulator.

Observations:

1. At one of the 220/132 Kv Grid Sub-station, one 220 Kv CT installed on the 220 Kv feeder burst with heavy sound. 2. The side cover of the CT got splited with oozing out of flame and oil. 3. Luckily, nothing any issues resulted due to such incident. 4. The CT was dismantled for detail study to find the cause of failure. 5. On internal inspection, it was found with burning of insulations inside the CT. The Bellow as observed was intact without causing any rupture/ expansion. 6. Grid in-charge was inquired about the behavior this CT during working operation condition. 7. As per statement, nothing such abnormality observed like oil leakage. || JULY 2022 ||

ELECTRICAL MIR ROR

8. This CT was drawing around 360 Ampere of current in average during the summer season. 9. The Marking of the Bellow as compared to the other available connected was doubtful. It was below the minimum mark, for which maintenance engineer has logged for corrective action. 10. But due to dedicated feeder, the shutdown action was under requisition with LDC (Load Dispatch Centre). 11. In between such, the failure resulted with damage as seen in the figure 2.2.1 and 2.2.2.

due to non-functioning of Bellow. 9. Due to non-functioning of bellow, the top part of the CT cover did not fly away for the damage, rather exert pressure on the side cover, resulting with rupture and gusting of oil with flame. Recommendation: It is recommended that Low oil level in the Top Tank CT should be viewed seriously. 2.3. Generation of Key gases in Transformer: One of the 40 MVA 220/33 KV Power Transformer was tripping on Bucholtz intermittently after charging newly after one month.

Case Study

Observations:

Fig 2.2.1 Faulty CT

Technical Analysis:

Fig 2.2.2 CT Oil Drained

1. This failure incident was analyzed after investigation of the burnt insulation on the top tank. 2. During inspection by Maintenance engineer, the situation of bellow had been suspected regarding its working action for expansion and contraction. 3. But the marking below the minimum line was indicating regarding oil leakage. Due to no leakage trace during working condition, the situation was not considered seriously. 4. During failure investigation, the leakage on the CT secondary console box was revealed by one of the operator. 5. This leakage was the culprit for reduction of oil level in the tank. 6. So air trap inside the top tank might have been the other cause of aggravating of the ionization and formation of gas. 7. The other reason is also the improper operation of bellow to accommodate extra expansion of oil during heating condition. 8. So, it was analyzed that due to oil leakage air enters into the Oil tank and dissolved with Oil, causing deterioration, further ionization and gas formation with heating of insulation and subsequent failure

1. This transformer was newly commissioned at one of the 220/33KV Grid Sub-Station. 2. The transformer was tested OK with pre-commissioning check and energized. 3. The transformer was loaded after taking into parallel to the other available transformer in the system. 4. But after charging of one month, the transformer started tripping on Buchholtz without any other relay indication. 5. The protection and testing team tested the transformer and found with no any abnormality and allowed for charging of the transformer. 6. But similar tripping with BUCHOLTZ repeated with no other faults in the system. Now it was decided for internal inspection by lifting the manhole cover. 7. On removal of cover, it was observed with arching blacken spot at one of the sharpen metal spacer as shown in the fig 2.3.1, which was kept in between clamping bolt and cover.

||www.electricalmirror.net||

8. This metal spacer has no specific role except provision of tightening of the clamp bolt. 9. This was nearer to the B phase 33 KV Bushing with insulating oil in between. The distance was bit nearer as compared to the actual distance compared to other Bushings. 10. Suspecting on this metal spacer, being the culprit, this was removed from the system. The oil was filtered and conditioned for next charging of the transformer. 11. On completion of the work, the transformer was successfully charged and loaded. 12. There after nothing such abnormal tripping was observed in the transformer.

5. On the next attempt, the transformer was taken shutdown for detail checking. 6. On physical checking it was confirmed with LESS OIL in the bushing but below the allowable limit. 7. TAN DELTA cap point was also removed, for internal inspection. It was found with arching at this point with blacken spot. (Refer Fig 2.4.2)

Technical Analysis:

1. This un-wanted metal spacer was kept during the time of manufacturing by the work men. 2. This might be due to adjustment for the clamping bolt. 3. During site testing, nothing was found abnormal as because of LOW voltage injection. Moreover, this piece was not with current carrying active part. 4. After successfully pre-commission test, the transformer was also charged and loaded as this was not coming directly with the current carrying part. 5. But due to less space from the live current carrying conductor, certain arching resulted on this metal spacer. 6. This arching result with evolving of objectionable key gases and accumulation of the same was resulting with actuation of BUCHOLTZ relay and tripping of the system with no other electrical relay actuation. 7. Initial days of charging, the accumulation was less and taking time for tripping of the transformer. 8. After tripping, the test results were not coming with any abnormal, as this portion was with the NON-CURRENT CARRYING metal part. 2.4. Replacement of 220 KV OIP Bushing: At one of the 220/132Kv Grid Sub-station, it was observed with some issues on one of the 220 KV OIP bushing.

Observations:

1. This transformer was of 160 MVA 220/132 KV Auto Transformer. 2. On site visit, it was observed with NO OIL on the bushing from the Top indicator of one of the bushing. (Refer Fig 2.4.1) 3. As it was of transparent type, the grid personnel were not monitoring the actual oil level. 4. Moreover, the oil monitoring frequency was of forth night basis.

||www.electricalmirror.net||

Fig 2.3.1 Sharpen Metal Spacer

Fig 2.4.2 Spark on TanDelta point

8. On the cap removal, the detail checking could be made possible, indicating of small arch inside the Tan delta point.

Action Taken:

1. It was decided for replacement of the affected Bushing. 2. The affected busing was accordingly replaced. 3. During replacement, top cover was removed for which filtration of the oil was done till of getting required proper oil test value.

Technical Analysis:

1. From the technical observation regarding the tandelta point after removal of the Cap, it was suspected that certain spark has been resulted due to detachment of earth with the cap. 2. This might have been resulted since long. 3. Moreover, reduction of oil level might have caused heating of the conductor. 4. Luckily the defect/ deficiency got traced in-time to avoid failure of the bushing.

Recommendations:

Reduction of oil level from OIL bushing must be checked properly and corrective action should be taken. EM

Procedure of Risk Management (Calculation) for Direct/Indirect Lightning-Practical Example Abstract: Lightning flashes can cause significant damage to structures and lines in a matter of microseconds which further lead to failure of associated electrical/electronic equipment resulting from resistive and inductive coupling of these systems with the lightning current. Moreover, lightning flashes may cause serious injury or become life threat to the living beings in and around the structure. The resulting effects of these hazards and failures might affect the surroundings as well. In order to mitigate the losses resulting from lightning and safely disperse it to the earth, protection measures need to be adopted. In order to understand the requisite measures for establishing a lightning protection system for structures, a proper risk assessment needs to be done in accordance with standard IS/IEC 62305-2. The calculated risk is compared with tolerable risk as per standard and the comment is to be made that whether the protection is required or not and if the protection is required, what should be the level of protection. Risk assessment is the first step to suggest the lightning protection system. In this article the overview of evaluation of risk is done with example. Keywords: Risk Management, Lightning Strikes, Protection against lightning, Ground flash density and Collection area. 1.0 Introduction Lightning is a dangerous event for any structure and life of living beings. Lightning may cause severe damage to anything which comes under the influence/effect of this. There are some pictures which can depict the effect of lightning on human life or structure directly or indirectly are shown in figure 1.

Lightning Protection 90

Fig. 1 (a) to (f): Effect of Lightning on Different Structures

Apart from these effects shown above there are some other effect of lightning like touch & step potentials due to high ground potential rise (GPR). So, ultimately the lightning is dangerous event and it is important task to safely capture the lightning current through lightning protection system which mainly includes the air-terminals, down conductors and earthing (Grounding) system. But before designing the lightning protection system for any structure it is important to evaluate the level of protection So, the role of risk assessment starts from here.

IS/IEC 62305-2 is the heart of IS/IEC 62305 that sets a precedent to the procedure of correct implementation of IS/IEC 62305-3 and IS/IEC 62305-4. It defines broadly the different parameters relating to the risk assessment of structures due to lightning flashes and evaluates the level of Lightning Protection System (LPS) to be installed. This standard deals with the complete framework of Risk Management wherein firstly the source of damage is determined followed by finding the structure to be protected. Next, the relevant risks are evaluated in reference to the specific losses which might appear in the structure. These risks are namely: R1: Risk of loss of a human life (including permanent injury) R2: Risk of loss of service to the public R3: Risk of loss of cultural heritage R4: Risk of loss of economic value There are different risk components according to the source of damage by lightning. The four types of sources of risk components are given as: S1: Lightning strikes to the structure S2: Lightning strikes near to the structure S3: Lightning strike at the incoming lines to the structure S4: Lightning strike near the incoming lines to the structure These four types of risk components to the source of damage can be understood with the help of Figure 2.

2.0 Factors Affecting Risk Assessment

Some of the common factors affecting lightning risk assessment of a facility are: 1. Areas with lots of humans 2. Salient organizations providing services 3. Areas that experience regular lightning flashes 4. Buildings that inflammable store items In addition to the above, some more important terms used in risk assessment are: 1. The lightning density means that the higher the density, the higher the exposure. This usually takes number of annual lightning strikes (per year per km2) into account. 2. Risk components related to lightning – include the risk of injury, physical damage and threat to the internal system. 3. The risk level of the building regarding the size of the surrounding buildings. 4. Significant losses – loss of human life, severe injury, economic losses, and service.

Fig.2 Different Sources of Damage due to Lightning

There are some terms used in the Figure 2 are explained as: RA: Factor refers to injury of living beings caused by an electric shock RB: Factor refers to physical damage caused by dangerous sparking within the structure RC: Factor refers to the failure of internal systems caused by LEMP (Lightning Electromagnetic) RM: Factor refers to the failure of internal systems- Flashes near structure RU: Factor refers to injury of living beings caused by touch voltage within the structure due to flashes to connected line ||www.electricalmirror.net||

RV: Factor refers to physical damage caused by the lightning current through connected lines RW: Factor refers to the failure of internal systems caused by overvoltage through connected lines RZ: Factor refers to the failure of internal systems caused by over voltage injected into the structure due to flashes near connected lines Furthermore, lighting risk assessment is done based on the required lightning protection level (LPL). Now, there are four levels of lightning protection i.e. LevelI, Level-II, Level-III and Level-IV

3.0 Methodology of Risk Assessment

The calculation of risk assessment shall be done in accordance to the standard IS/IEC 62305-2. The procedure considers calculating a risk (R) which shall be compared with selected tolerable risk (RT). A lightning protection level is then chosen accordingly to ensure that the calculated risk level is lower than the considered tolerable risk. It is very clear from IS/IEC 62305-2 that several parameters are considered when risk to any structure is calculated. It is not that only the structures are in danger from lightning, but our electronic and electrical equipment is also in danger. Therefore, there are two kinds of effects of lightning strikes: Direct Effect: This effect occurs when lightning directly strikes a structure. We use special conductors to prevent damage from such an effect. Indirect Effect: This effect occurs when surge voltage generated by a lightning strike causes potential damage to the devices in the structure. Each primary risk is carefully calculated according to the standard IS/IEC 62305.In addition, if the actual risk (R) is less than or equal to the tolerable risk (RT), no protection measures are needed . However, if the actual risk (R) is greater than the tolerable risk (RT), the protection measures must be installed. The level of lightning protection system is decided according to the tolerable risk found. This can be understood with the help of Figure 3.

Fig.3 Block Diagram Representation of Risk Calculation

In simple words, when R > RT, we install a lighting protection system for safety purpose. The level of lighting protection system is installed according to the tolerable risk found. The steps for calculating the risk are given in figure 4. ||www.electricalmirror.net||

Fig.4 Flow Chart for Steps to Calculate Risk

This procedure of finding the risk from lightning can be understood with the help of flow chart. It clearly shows all the basic steps to check whether the structure for which the risk is being calculated is protected or unprotected. Typical inputs required to calculate risk are given in Table 1.

Calculation for indirect collection area(Am): Am=2×500×(L+W)+π×(500) 2 Am=831398m2 Step-2: Calculate ground flash density (Ng) with the help of annual thunderstorm days (Td). Annual thunderstorm days (number of direct lightning strikes in 1 / year / km².) for location Delhi is 30. Now ground flash density: Ng=0.1×T_d Ng=0.1×30=3.0 Number of dangerous events (Nd) for the structure is calculated as: Nd = Ng × Ad × CD × 10-6 Nd = 3.0× 2566 × 0.25× 10-6 = 0.001924 strikes /year Similarly, numbers of dangerous events are calculated for adjacent structure, strikes near the structure, strikes to a line and strikes near a line. Step-3: Relative location of the structure is considered by taking reference form IS/IEC 62305-2 Table A-1. Location factor (CD) is 0.25 for this building as it is mentioned that the building is surrounded by higher object and other parameters given in above Table 1. The tolerable risk (RT) are considered from IS/IEC 62305-2. Here the worst case is the risk of loss of human life i.e (R1). R1 (tolerable)= 1.00x10-5 R2(tolerable)= 1.00x10-3 R3(tolerable)= 1.00x10-4 R4(tolerable)= 1.00x10-3 Step-4: Now, Risk calculated as per the formulas given in eq. (1) i.e. RX = NX × PX × LX NX = dangerous events per annum (0.001924 strikes/ year) PX = probability of damage to a structure = PTA× PB (values of PTA& PB are considered form Table 4 and Table 5 respectively) LX = consequent loss to damages relevant to the structure are considered as per Table C.7 & Table C.11 of IS/IEC 62305-2. By considering all four different risk components (S1, S2, S3, & S4) according to the source of damage and considering Table 5 of IS/IEC 62305-2 for parameters relevant to the assessment of risk, the risk calculation has been done. As per the formulas given in eq. (1 ) the calculated risks (R)

for the building are R1 (without protection) = 1.24x10-5 R2 (without protection) = 6.19x10-6 R3 (without protection) = 6.19x10-5 R4 (without protection) = 5.45x10-4 Step-5: Now, the calculated risk is compared with highest tolerable risk (RT) i.e. all four type of risk as per IS/IEC 62305-2. Here, the calculated risk (R) is more than the tolerable risk (RT) for R1 that is risk of loss of human life. All other three losses are coming within the tolerable limit. So, protection is required to reduce risk R1 only. Step-6: Now, the protection measures will be given to reduce the calculated risk below the tolerable risk. In this case if Level-IV of lighting protection is considered the calculated risk as per formula given in eq. (i) R1 (with protection) = 6.77x10-7 R2 (with protection) = 3.39x10-7 R3 (with protection) = 3.39x10-6 R4 (with protection) = 4.81x10-4 It shows that Level-IV of lightning protection is enough to protect the building from lightning strikes. So, Level-IV of lightning protection shall be considered for this particular building. The effect of considering lightning protection system for any structure can be understood from Table 5.

Let, if the calculated risk after considering Level-IV protection is not coming below the tolerable risk then further the risk shall be calculated by considering Level-III lightning protection and the process will repeat till the calculated risk comes in the limit of tolerable risk.

5.0 Conclusion:

The different types of risk form lightning strikes are explained to make peoples understand. Different sources of damage due to lightning are also covered here. Concept of collection area of lightning and its effect is given with formulas. Most important, a practical case of risk management for a building is also given here with suggested lightning protection level.

EMI Issues in Electric Vehicles The use of high-power electronics to drive the electrical engines of the new electric and hybrid vehicles produces high-level low-frequency EMI. In hybrid cars, this new emission is added to the ignition system one. In this paper, some EMI measurements including current, near and far electric and magnetic field in two cars and a bus are presented. Some issues in the standards and tests setups must be updated: cars cannot be measured in idle state, new LISNs must be used in the high-power network, magnetic field evaluation for safety is mandatory in some vehicles or to consider radiated transient measurements.

I. Introduction

In the upcoming years, the wide use of electric and hybrid vehicles will produce a new level and type of interferences on the streets and roads. The current combustion engines vehicles usually produce two main types of electromagnetic interference (EMI): the ignition system, the electrical motors and the switches producing broad band EMI and the electronic devices generating narrowband interferences. Electric vehicles use high-power electronics to drive the electrical engine which produces high-level low-frequency EMI. In hybrid cars this new emission is added to the ignition systems one. Plug-in electric vehicles introduce a

new device in the mains network and, because their characteristics and the power involved, special considerations must be taken into account. The standards and test setups must be updated to manage this new EMI source: vehicles cannot be measured in idle state assist is done with combustion ones, the electrical engine must be running and under load; this requirement inside an anechoic chamber represents a new challenge for the test sites. The assessment of the devices connected to the high-voltage network requires the use of new type of LISNs. Due to the high currents involved, magnetic fields inside the vehicle could be large therefore, evaluation for safety is mandatory for certain types of vehicles. Radiated transient signals area new issue that must be considered in electric and hybrid cars. The ever increasing concern to deal on regional and global level with the potential consequences of vehicle fuel emissions on the air quality has elevated the need to electrify and decarbonizes the transport sector through the penetration into the market of electric based automobiles. In this regard, automotive manufacturers are introducing new and cleaner technologies within electric-based vehicles to respond to this demand. Electric vehicles (EVs)

e.g. Plug-In-Hybrid vehicles (PHEVs), battery EVs (BEVs), etc, accommodate a huge number of complex high and low power electrical and electronic subassemblies. These advances on EVs have to be regulated collectively with their recharging systems, which have to deliver higher charging power and currents into bigger vehicle battery capacity, faster and efficiently. Together with this trend, the control and suppression of the electromagnetic interference (EMI) generated by these systems becomes increasingly challenging due to the fast changing signals utilized by the high electric currents . Effective EMC practices are essential to ensure the safety and functionality of the underlying systems and components. For vehicles and their recharging systems this is governed through automotive EMC standards i.e. UNECE Reg. 10 , IEC 61851-21-1/2 . These have been around for years, yet the test methods prescribed for EMC compliance do not fully reflect these of real world setups and/or actual operating conditions. EMI generated noise from the components of electric vehicles and charging units e.g. DC to AC converters, electric traction motors, EV batteries, etc have been discussed. However it appears that there is lack of published data on the EMC aspect at system level i.e. when a charger is charging an electric vehicle. In addition, CISPR 12 test methods for the radiated EMI from vehicles quoted on UNECE Reg. 10 consider static conditions only and/or are too old to serve adequately their purpose in modern vehicle technologies.

engine of this type of vehicles is no longer linked with the wheels. Motion is produced only by the electrical engine while the combustion one is used only to charge the Accumulative electrical devices, in this case, a set of ultra capacitors. The main advantage of these series-hybrid vehicles is that the combustion engine regime can be optimized in terms of consumption and pollution. Their drawback is that the electrical engine alone must have enough power to drive the bus in all situations.

Figure1. Hybrid vehicle architectures. a) Parallel,

b) Parallelplug-in,

II. Hybrid vehicles

Different types of hybrid vehicles are being developed nowadays [2]. In this work, the electromagnetic interferences generated by three of these hybrid vehicles have been analyzed. The first one is a commercial parallelhybrid vehicle (Fig. 1a). In this kind of vehicles the combustion and the electric engines are in parallel, which means that both are allowed, and have the enough power, to move the car. The tested vehicle has a relatively low-capacity high-voltage battery that allows driving the vehicle in full electric mode for few minutes. The electrical engine power is only 60 kW therefore, when high torque is demanded both engines work in parallel. High-voltage batteries are charged when the combustion engine is started and when the regenerative breaking is in operation. The second vehicle tested is a prototype of a plug-in parallelhybrid car (Fig. 1b). As the previous one, it has two engines working in parallel but this time the electrical system has larger power (85 kW). Furthermore, it is a plug-in vehicle, which means that the high-voltage batteries could be charged from a mains outlet. Of course, batteries are also recharged when the combustion engine is running and when breaking. The last vehicle is a series-hybrid bus (Fig. 1c). The combustion

III. Standards and test sites update

EMC standards and test houses are currently focused to measure combustion engines and several modifications must be introduced to make a good assessment of the electrical/hybrid vehicles. Several initiatives are under development in different committees and bodies to define the proper changes. In this work, after performing some EMI measurements of the two cars and the bus defined above, some suggested improvements are listed below. • Standards and test setups must cover the low frequencies where EMI is produced. Magnetic fields at frequencies as low as 100 kHz must be limited. At that frequency range, only the electric field is currently measured in automotive EMC issues but, because power currents are involved in electrical engines, the magnetic fields are also important. Furthermore, measurements regarding personal safety to magnetic fields are also encouraged in high-power electrical vehicles. • Plug-in vehicles joint the nowadays separate worlds of ||www.electricalmirror.net||

Figure 2. Radiated EMI from a chassis Dynamometer in passive operation.

• Another issue is the reference point to perform the measurements. Up to now the measuring antenna is ||www.electricalmirror.net||

placed at a certain distance in front of the combustion engine. In electric cars, batteries, power inverters and electric engines are distributed in the vehicle and linked by power cables. Most of the times these cables are the main EMI source; therefore it is not easy to define a specific point in relation with the vehicle to place the measuring antennas. Turning the EUT (Equipment under Test), as it is done in other products, could be a solution but it is a challenge to combine this requirement with the previous motion and loading one inside an anechoic chamber. • Radiated transients are a new issue that must be addressed in electric cars. The inverter pulsed power signal, the car motion starting, the regenerative braking or the battery charge connection produce transients signals in the vehicle. that can produce radiated interference that can up set wireless devices operating inside and outside the vehicle.

IV. EMI measurements in hybrid vehicles

In this section several measurements performed on the different vehicles are presented. Some of the measurements have been made on the road, others in a garage with the vehicle jacked up and also in an anechoic room. Current on the cables upto100MHz, radiated fields and magnetic fields outside and inside the vehicles have been considered. Fig.3 shows the current measured on the unifilar (positive) shielded cable that links the battery and the electrical engine of the hybrid car. Four different plots can be seen in the figure. The first one is the ambient noise, which is very low because the measurement is done with a current probe. When the car electrical mode is turned on, but with the electrical engine stopped, we can see a certain EMI level. This level increases when the car is running and the interference is particularly high at low frequencies up to 50 MHz. Although currently there are no standard limits for EMI currents in the whole car, in Fig.3 the CISPR 25 limit for components is plotted to have a reference. As it can be seen on the plots, some increase is measured above 40 MHz, when the vehicle is under load, running on the road instead of jacked up.

automotive and mains network in domestic, commercial and industrial environments (low-power single-phase but also high-power three-phases charging operations are planned).From now on, the car must be considered as another appliance connected to the mains network. Standards must address this issue defining the parameters that must be measured and the limits to apply. Details, like which operation modes are allowed during charging, are important. As an example, if electrical air conditioning is allowed during the charging operation, the power involved and the EMI level will be larger. • If a component level EMC approach is desired (like now happens with the worldwide used CISRP 25 standard), new test methods must be defined in the high-voltage network. New Line Impedance Stabilization Networks (LISN) able tomanage300Vorlarger are needed. Current probes are an alternative to those LISN high-voltage measurements. • Several details must be solved in the test setups. One main concern is about the vehicle operation when measuring radiated EMI. Up to now, combustion engine vehicles have been measured inside anechoic chambers in the idle estate because ignition system is the major broadband EMI source and no vehicle motion is needed to measure the maximum emission level. Now, the electric vehicles do not have a representative idle mode from the EMI point of view. Power inverters, electric engine and wheels must be in operation and under load when radiated emissions are measured. The chassis dynamometers currently used in test sites to perform immunity vehicle tests are no longer useful to measure radiated EMI because they become themselves a radiated emission source. Fig. 2 shows the radiated EMI from one of this load drum in passive operation. Red line shows the European EMC Automotive Directive limit for radiated emissions. The EMI level generated is larger than the current limit stated in the standards. When the drum is in action, loading the car, the emissions are even larger.

Next results have been obtained in an anechoic chamber with the vehicle jacked up. Fig 4 shows the electric field measured with and active rod antenna located at 1 m distance from the car. Some radiated emissions can be clearly seen in the 5-30 MHz frequency band. Another time this EMI level is compared with the CISPR 25 limits for components. In this case the emissions of the whole car are below the limits considered. Because high level currents are always involved in hybrid and electric vehicles, some near field magnetic field measurements have been done with an active loop located at 1 m distance from the car. Since there are not mandatory magnetic field measurements in the current standards, the results have been converted to V/m to be compared with the current electric field limits. Far field E/H=120 Ω condition has been applied as usual, although it is not necessarily true in this near field situation. Fig.5 shows the magnetic field results. The measurement has been performed in a garage, where the EMI produced by the car operation is clearly above the ambient noise level. In this case, the emissions are larger than the limits stated in CISPR 25 for components.

above this frequency range produce no significant EMI levels. Even in this lower frequency band, the emissions, although can be detected, are quite low and always under the standard limits. Some further measurements have been performed when the vehicle is starting and in the regenerative breaking mode. When starting, 10 dB increments have been measured in the 40-50 MHz frequency band. When braking, and therefore charging the batteries, no significant increase has been noted. Last measurements have been done in a hybrid bus running inside a large garage. In this case our interest is the assessment of the electromagnetic fields present inside the vehicle that could affect the passengers. The bus main electric system is tribution is depicted in Fig.7a. The electric accumulators and the inverters are on the roof and the electric engine is under the passenger seats with a cable that links them at the rear part of the bus. Fig.7b shows the magnetic field levels measured with a handheld meter in some seats on the vehicle rear part. Although the levels are noticeable, all the values are within the limits established by the standards for personal safety.

B. Test methodology for chargers During the EMC measurements and for reassembling as closely as possible real world setups and operating conditions, the recharging stations, wired according to the documentation defined by the manufacturer, were placed next to the electric vehicle inside the EMC chamber. As the priority was to explore in a pre-normative manner the EMI levels generated by the combined effect of EVSE-EV systems, some recharging cycles during the EMC tests were recorded both in time and frequency domain to understand the individual contribution of each recharging phase. The latter included the EMI effect due to (i) plug-in, (ii) preparation for charging, (iii) charging of vehicle, (iv) termination of charging and (v) unplugging. In addition, for some samples, empty-to-full battery recharging cycle was performed whilst the state of charge (SoC) and AC-grid power was monitored together with the generated EMI from the entire infrastructure.

C. Test methodology for vehicles

Vehicle EMC testing methods based on UNECE Reg. 10 and CISPR 12 on the radiated emissions from the whole vehicle under dynamic and realistic driving conditions beyond the legislative

testing methods have been shown by the author to underestimate actual level of EMI. A series of EMC testing methods were conducted on the vehicle samples for the determination of the EMI levels. These methods were proposed and demonstrated analytically in and are summarized here: • Time-dependence analysis of the E-field during a complete drive cycle up to a maximum speed (at a fixed frequency) vs. vehicle’s electromechanical parameters such as power delivered from the EV DC traction battery, speed, etc. • Extraction of the radiation pattern around the vehicle during constant speed (at a fixed frequency). • Successive frequency domain captures of the EMI for the intermediated phases during a driving cycle, including different constant speeds.

VI.

Conclusion

New hybrid /electric vehicles produces new EMI issues that must be addressed in order to perform a correct EMC assessment. Standards, test methods and testing houses must be updated to include the low frequency electromagnetic emissions of the electric engines and the power electronics. EM

The process of transferring the immediate discharge of the electrical energy directly to the earth with the help of the low resistance wire is known as the electrical earthing, and also known as grounding. People depend on earth in all manner. There is a need for earthing in homes, factories, offices, etc. People should be aware about the electric meter services at homes. MCB and proper connection are good but Earthing is also more important for saving from electric shock, Earthing is also more usable with Voltage Stabilization and Overload protection. In our daily life we need earthing but some materials are mandatory for this like Earth continuity Conductor, Earthing Lead, Earth electrode. What is Earthing and How does it work? A safety measure device to prevent people from getting shocked if the insulation inside electrical devices fails is called 'Earthing'. The Earth, being a good conductor of electricity, acts as a convenient path for the flow of electrons that escape the insulation. In technical terms, electrical earthing can be defined as the process of transferring the immediate discharge

of the electrical energy directly to the Earth with the help of the low-resistance wire. As mentioned earlier, earthing provides a simple path for the leakage current i.e., the current that escapes from a device if there is any fault in the insulation. When due to any reason there is a fault in any device or machine, the metallic part is also having current that can cause electric shock for the person who is using a particular device or machine. If machines or devices are set properly on the earth, it will not harm anyone. How Earthing Came into Existence? Electrical devices were not always grounded. Humans first began using electricity in their homes in the 19th century. Initially, we were not aware of the potential dangers of current when it comes in contact with the human body. Between 1880 and 1920, the transmission and distribution of electrical power were carried out via unearthed neutral connections. The supply lines were uninsulated and placed out of reach so that humans wouldn't come in contact with them. It was a massive recipe for disaster. During these years, many people had to ensure electric shocks and rampant blown ups.

Earthing

Why is Earthing/Grounding Necessary?

There are 3 main reasons why all electronic devices need to be connected to the Earth. 1. Human Safety A properly earthed device doesn't leak out any current. This prevents humans from getting shocked if any internal faults in the device occur. 2. Safety of Electrical Equipment Earthing provides stability to electronic equipment. It prevents over - current or excessive voltage in appliances. Over voltage can cause the device to spontaneously combust due to overheating, so technically, earthing is also a fire prevention measure. 3. Protection of Buildings from Lightning It is interesting to note that, apart from the electrical appliances, large structures such as skyscrapers are also earthed. The earthing device is in the form of lightning arrestors, which are placed at the highest point of the building and connected to the ground via a conducting wire or plate. In the scenarios when lightning strikes a building, the copper lightning arrestors draws in the jolts of lightning and transfers that massive amount of energy to the ground, thus preventing any damage to the structure or harm to its occupants.

Difference between Earthing and Grounding

Although there is no major difference, we use non-current carrying part in Earthing at variance with current carrying part in grounding. Earthing saves the person from electric shock and grounding protects the power system. Grounding is not having zero potential. There are three types of grounding 1. Solid 2. Resistance. 3 Reactance. The color of the wire is black. 110

Now and then Grounding is used to make an unbalanced load to balance. Earthing carries zero potential and use of saving from electric shock. Types of Earthing 1 TN-S, 2 TN-C-S, 3TT, 4 TN-C, 5 IT. The color of the wire is green.

Types of Earthing

1. Stripe and Wire Earthing Strip and wire Earthing basically use with electrode which section should be 25mm*1.6mm minimum. It is set in the earth up to 5 meter. These Eathings are used mostly in mountain areas. 2. Coil earthing Coil Earthing Are made by 8 SWG wire with 50mm diameter coil. We need to dig a whole at least 1800mm depth and 600mm section. 3. Pipe Earthing A galvanized steel pipe is placed in the soil. The pipe is drilled with holes for connecting the earthing wires. The length and diameter of the pipe depend on the type of soil and electrical installation. Pipe earthing GI pipes that are set in the ground 2 to 3 meter up to, and depth depends on the nature of soil and water. 4. Rod Earthing Rod Earthing is a 12mm copper rod and fits in the earth. This is almost identical to pipe earthing as it requires the burying of a rod made of copper or galvanized iron. The Rods are in the form of electrodes, which are embedded in the soil, thus decreasing the resistance of the Earth as required.There is a need to connect a copper wire with clamp so that it is easily attached with equipment.

5. Plate Earthing Plate Earthing employs a copper or galvanized iron that is buried vertically into the earth in a pit. This pit is more than 10 feet deepPlate Earthing are done by copper plate with the size of 60cm*60cm*3.18mm and also we can use GI plat. 6. Clamp Earthing Earthing through water mains is used by ground water pipe and clamp with GI plate or copper wire. But ground water pipes should be metallic so that fault current can be neutral. 7. Water main method This method uses water mains, i.eGalvanized GI pipes. These pipes are buried in the earth and clamped using earthing clamps, which minimise the resistance of the electrical connection.

Earthing

What factors affect earthing installations?

• Several elements need to be considered before carrying out earthing installations; • The type of soil is crucial for calculating the effectiveness of the earthing. Earth's resistance, moisture level in the soil, salts in the soil, etc. will also play a significant role in determining the way the earthing is made. • Apart from the soil, the location of the earth pit is important to determine how the installation should be completed. • Another major factor is the composition of the soil. For example, rocky soil must be treated very differently than wet soil. • To those who have been stung by the wrath of excited electrons, you know who to thank - Mother Earth with her zero potential has probably kept you alive more times than you can count!

India Electricity Rules

The Rule was implemented in 1956 for the connection with the earth system. There are some conditions that don't exceed volts limit. In the case of a system comprising electric supply lines having concentric cables, the external conductor of such cables shall be earthed by two separate and distinct connections with earth. There should be a link in the connection for the purpose of testing or for locating a fault. In a direct current three wire system the middle conductor will be earthed at the generating station only, and the current from the middle conductor to earth will be continuously recorded by means of a recording ammeter, and if any time the current increase one-thousands part of the maximum supply-current immediate steps will be taken to improve the insulation of the system. No person shall make connection with earth by the aid of, nor shall be keep it in contact with, any water main not belonging to him except with the consent of the owner thereof and of the Inspector.

The impact of COVID-19 on the Global Market of the Gensets! The COVID-19 outbreak has negatively affected the global economy as the operations of various sectors have come to a halt. In the power generations sector, co9mpanies are dealing with several challenges due to a decline in demand for electricity post COVID-19. Moreover, industries such as construction, manufacturing, tourism, and the operation of events had stopped completely which has drastically impacted the genset market globally. As the demand for electricity had declined globally so the demand for new diesel gensets had also declined. The nationalwide lockdown to contain the spread of COVID-19 pandemic is set to magnify the already stressed finances of electricity generators and distribution companies. As a fall out of the lockdown, the finances of the discoms are impacted since they are not able to collect payments from consumers and in turn pay to the generators. A report of CARE Ratings state that “State governments would further delay the release of subsidies. Given that usually most of the payments for past supply are collected/made towards the end of the financial year (March), the delays would have significant financial implications. Although since August 2019, states have been making monthly payments to generators after the power ministry made it mandatory for discoms to maintain LC (letter of credit) as payment security for power purchases, there exists sizeable past dues that are to be cleared. Further, the fall in demand would impact revenues of generators and distributors alike.” The financial profile of the state distribution utilities or discoms has not seen an improvement in 2019-20. The transmission and distribution losses and the outstanding dues of discoms have not seen a reduction during the year. The inability of states to hike tariffs, rising operational expenditure, high levels of outstanding dues and delays in receipt of subsidy from states has weakened the financial position of state distribution utilities. The AT&C (aggregate technical and commercial) loss of discoms at the all India level at 19.1 per cent is above the UDAY (Ujwal DISCOM Assurance Yojana) target of limiting the losses to 15 || JULY 2022 ||

per cent by FY19. The gap between ACS (average cost of supply and average revenue realised (ARR) at the national level is Re 0.36 per unit against the target of elimination of the gap in FY19. The outstanding amount of discoms as on end January end as per data from Payment Ratification and Analysis in Power Procurement for Bringing Transparency in Invoicing of Generators (PRAAPTI) stood at Rs 88311 crore of which Rs 76192 crore (excluding disputed amount) was overdue. There has been a 27 per cent increase in outstanding amount since April 2019 and 42 per cent increase in the overdue amount. “The domestic power sector is feeling the impact of the global spread of the virus and the resultant lockdowns. It has not only led to a fall in electricity consumption, but has impacted the supply of key inputs for generators which would lead to project delays and thereby time and cost overruns”, the report added. The economic disruptions following the lockdown of the country to contain the spread of the virus has further dented electricity demand from the industrial and commercial sector in the country. Consumption of electricity has declined across states. The daily power demand in the country has fallen by 25 per cent since the middle of March when most parts of the country imposed restriction and shutdowns. Electricity consumption in the country fell from 3,494 million units on March 16 to 2,628 million units on March 28. The drop in consumption has been notably higher in the northern and western regions of the country – a fall of around 30 per cent. The southern regions have reported a decline of 19 per cent.

Power Factor Correction: Future Market Insights! Introduction In the production of power, there are a lot of inductors used in AC machines like transformers and motors. Inductances are caused by the magnetic fields, which are produced by the currents flowing in the electrical circuit. Basically, the coils of wires are employed as the coil increases the magnetic field coupling. In the process of transmission of power, the power factor shows the effectiveness of the electricity used. The improvement of the power factor is very significant economically as it helps to reduce the electricity bill. Improving the power factor is a verified technique of improving the effective usage of the electricity through the utilities as well as the end-users (final consumers of electricity). The economic benefit for the final consumer of electricity is lower power losses in the cables as well as in the transformer. Increased power factor also helps in reducing the electricity bills and improving voltage conditions as the benefits of utilities from the system release capacity. The real power is taken as the power for producing work, which is always given in watts (kilowatts).

The reactive power, which is due to the indicators and capacitors is not used to do any work, but it is needed in AC 3-phase power system for the equipment to operate. Several Industries loads are inductive, like the transformers, motors, industrial incinerators, and induction furnaces. The current drawn by the inductive load includes two key components: the power-producing current and the magnetizing current. The magnetizing current is needed to sustain the electromagnetic field in the component and generate reactive power. The inductive load will draw current, which always lags the voltage. Thus the real power and the reactive power shows how much power the electrical power will use. The PF also in the cosine angel between the current and the voltage in the phasor diagram. For the electrical loads which are inductive like motor, they consume of about 80 percent to 90 percent which is delivered to them while the remaining percentage of power (10 to 20 percent) delivered is wasted as they are employed to establish the electromagnetic field in the machines. The electromagnetic field

will expand and collapse, so the drawn power to the field in one instant is just a return to the supply of electrical power in the subsequent instant. The mean power drawn by the magnetic field will remain zero, and the reactive power doesn’t appear in the meter of kilowatts-hour. The magnetic current will generate reactive power. Even though it does not do useful wo9rk, it will circulate between the places and the generator to heavily drain the power source. To reduce the reactive power, some banks of capacitors are added which is an economical technique to adjust the power factor. As the current via an inductive load will lag the voltage, the current will lead the voltage in a capacitor. Accordingly, the capacitors are added to serve as leading reactive current producers to help0 counter the lagging reactive current in electrical transmission. The release of capacity implies that the total current flowing will be minimized as the system’s power factor. This will allow the extra load to be included and severed by the available system. In case the equipment like the generators, cables, and the transformers might be thermally overloaded, by increasing the power factor, the current will be minimized and overload condition will be eliminated. Basically, the correction of power factor should be encouraged by applying penalties which is introduced by some utilizes. When entirely considered, there may also be some economic factors that may result in capacitor’s addition for power factor correction, which gives a justifiable investment return. There are also other savings like the reduction in the distribution losses, increased voltage reduction, and current

increased facilities. Even though the real power often produces little in the savings of cost and is smaller than the saving to be gained from the power factor penalties reduction Power Factor Correction PFC refers to a series of methods which are employed to improve an electronic device’s power factor. This not only improves the power quality of the system, followed by the reduction of the load on the electrical distribution system, but also improves the energy efficiency and ensures a reduction in electricity costs. In addition, PFC also decreases the likelihood of grid instability and failure of electric equipment. Power factor correction devices are also known as power saver devises. It is connected to the mains of the electrical system for improving the power factor measurement taken using an electricity meter. Power factor correction devices measure how efficiently power is consumed. Therefore, the power factor correction devices don’t affect the utility bill based on real power but it is useful for industrial users where the powe4r charges are based on PFC rather than real power. Ideally the power factor will be unity of 1 i.e. 100 % when the current and voltage simultaneously achieves maxima, but due to highly inductive load, devices in the real world, it is reduced to 0.7 or less. The capacity of a circuit performance at a particular time is real power. It is noticed that load/device with a low power factor takes more current than high-power factor devices in the electrical system for the same amount of power transferred. However, energy loss is also more in the distribution of higher current in the system. It is also requires higher capacity ||www.electricalmirror.net||

wires and equipment. And due to the extra expenses and the wastage of current, power companies charge a higher cost to low power factor users, which are usually industrial and commercial customers. This is mainly caused by lightly induction equipment; any device that has a coil of wire will create low power factor, such as ACs, pumps, fans, blowers, induction heaters, weaving machines, standard stamping machines, single-stroke presses and automated machine tools. So, the power factor correction devices are used to raise the power factor of the respective devices and reduce the electricity bill. The vigorous growth in HVAC (heating, ventilation, and air conditioning) systems across the world and increasing awareness among people to save electricity by connecting power factor correction devices to the electrical system led to notable increase in demand for power factor correction devices. The implementation of energy-efficiency norms and standards for the development of public lighting and power system is also expected to bolster the demand for power factor correction devices over the predicted period. Increasing Efficiency by Identifying Power Factor Correction Problems The general dereliction in the economy is forcing many households to look at effective savings in their mo9nthly expenses and energy is one of the major head of the expenses that needs attention. Since it is something that cannot be avoided, the smart trick is to monitor its usage and take such steps so that there is less wastage. You need to optimize its usage rather than cutting down on it. In this contemplation, having knowledge about the power factor and its influence on the efficiency of your electrical system is essential to identify. Basically power factor is a measurement tool that determines how the electric supply or energy delivered to your house by the energy utility company is bei8ng used by the electrical set up. For example, if you have devices that have resistive loads such as the electric stove or devices that have a motor referred to as the inductive load, they would require more power to function effectively and their power factor performances would be towards the lower end. It basically indicates inefficiency in utilizing the energy being sent to your house by the utility company and that is where you need to assess and take corrective steps to push this power factor rating through a power factor correction exercise.

This can be done through the installation of a power factor correction device as it would use the supplied energy more efficiently and reduce wastage. These devices also help in increasing the durability of devices due to their ability to supply just the right energy to the devices and ensuring that they are not subject to repeated fluctuations in the supply. Replacements of motor-operated devices and even fluorescent bulbs would not be too frequent and you would be able to make your own significant contribution to a greener environment. It is noted that the reduction in power usage as well as efficiency is greater in homes with a lot of inductive load as visible in the air conditioners, fans, washing machines, refrigerators, dishwashers and so on. Many people feel that the food processor, grinder, computer fans and exhaust fans don not consume much power but you would be surprised to know that due to their inductive load, they are also significant contributors to your energy expense. It therefore follows that an average home which does have all the above mentioned devices would stand to gain a lot through these power factor correction devices and there is indeed great merit in going for them. Using a power correction device is an excellent way to go green and save the money at the same time.

Transformational Growth

The renewable energy sector in the country witnessed transformational growth in last few years, in terms of both installed capacity and increasing share of renewable energy (RE) in total power generation of the country. The growth is driven by the government’s efforts to create a conducive policy and regulatory environment. Also, the developments in power sector such as modernization of transmission capacity and distribution networks, electrifying villages and extending

power to all households, have resulted in improvements in energy consumption, fiscal discipline in utilities. Over the years, renewable energy sector in India has emerged as a significant player in the grid connected power generation capacity. It supports the government agenda of sustainable growth, while, emerging as an integral part of the solution to meet the nation’s energy needs and an essential player for energy access. It has been realized that renewable energy has to play a much deeper role in achieving energy security in the years ahead and be an integral part of the energy planning process. The country aims to strengthen its energy security and independence by developing renewable energy resources. These include stringent norms for the construction and operation of energy generation equipment and increasing reliance on more advanced generation technologies in the field of renewable. So there is a great need of renewable energy source in Indian power sector to meet future energy demand and remove Green House Gases (GHG) emission for environment protection. In this connection Government of India has come up with Acts, Policies and regulations to support renewable energy. The Electricity Act 2003 that was notified by the Ministry of Power in June 2003 with other policies National Electricity Policy and National Tariff Policy appears to be in the helm of affairs for the promotion of renewable energy at the state as well as to national level in India. The Act and policies also emphasizes the importance of setting renewable energy quotas and preferential tariffs for renewable energy procurement by the respective SERCs in their restructured states power sector. India is witnessing a radical change on account of the government’s move towards power generation via renewable energy resources; Government has set a target to achieve175 GW renewable energy installed capacity by 2022. This includes 60 GW from wind power, 100 GW from solar power, 10 GW from biomass power and 5 GW from small hydro power. Further, with increased focus on offshore wind power, floating solar parks and hybrid parks etc., it is expected to over achieve the target by 2022. The increased focus of Government of India (GOI) towards renewable energy has created attractive opportunities for investments in this sector. Government has rightly recognized RE to be seen not only as sources of energy, but also a tool to address many other pressing needs, including improving energy security and access; reducing the health and environmental impacts and mitigating greenhouse gas emissions.

Pradesh, Maharashtra, Rajasthan and Tamil Nadu rich in renewable resource potential and where large capacity renewable power projects are planned, at an estimated cost of Rs.10,141.68 crore with Government of India contribution from National Clean Energy fund 40%. The activities envisaged under the project includes establishment of 48 new Grid sub-stations of different voltage levels by installing over 7800 ckt-kms of transmission lines in these seven states. The project is proposed to be completed within a period of three to five years. Creation of an intra-state transmission system will facilitate evacuation of renewable power from generation stations to load center. At present India is fifth largest country in the world in electricity generation, having presently aggregate capacity of 360 GWs as on July’ 2019, out of which approximately 63% is from thermal, 12.5% from hydro, 2% from nuclear and the rest about 22% is from renewable energy sources. Although Indian power sector has experienced a more than ten-time increased in its installed capacity in 1981 to till date but still there is need to be establish more generation plants preferably to be come from renewable sources by governmental as well as various private participation. Contribution of renewable energy sources in the total capacity as well as gross generation is still very low. The Indian power sector is predominantly based on fossil fuels, with more than about three-fourth of the country’s power generation capacity being dependent on vast indigenous reserves of coal. But in few last decades Indian government has taken several steps to reduce the use of fossil fuels-based energy while promoting renewable generation. Core drivers for development and deployment of new and renewable energy in India are Energy security, Electricity shortages, Energy access and Climate change. India has taken a voluntary commitment of reducing emission intensity of its GDP by 33-35 per cent from 2005 levels by 2030. The Government has also approved a Scheme, in December 2014, for setting up of 25 Solar Parks, each with the capacity of 500 MW and above and Ultra Mega Solar Power Projects to be developed in next 5 years in various States and will require Central Government financial support. These parks will be able to accommodate over 20,000 MW of solar power projects. As on date, parks with capacity of about 20,000 MW in 22 states have been sanctioned. Globally China is the country leading first position in renewable installed capacity in the world. With regard to source-wise installed capacity, world-wide China is leading first position in Solar Energy, Wind Energy and Small Hydro power.

It is not hidden anymore that India has a vast supply of renewable resources and it has one of the largest programs in world for deploying renewable energy products and systems. India is the only country in the world to have an exclusive ministry for renewable energy development, the Ministry of New and Renewable Energy (MNRE) which has launched one of the world’s largest and ambitious programs on renewable energy. This article gives a brief overview of various renewable energy resources, their status in India, the socio-economic impact of renewable energy resources (RES), challenges associated with it and the future of RES in India.

Introduction:

Energy is regarded as the most important building block in human development and it is a key factor that influences the sustainable development of any nation. The conventional sources have an intimidating shadow on our present and future global safety, environmental values, health and society in general. Hence, there is an urgent need to promote renewable energy in Indian power sector. Renewable energy is the energy collected from renewable resources, which are naturally replenished on human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. It is the cleanest source of energy with least carbon emissions or pollution. This helps on reducing reliance on coal and other fossil fuels. With the expansion of renewable energy, India can improve air quality, reduce global warming emissions, create new industries and jobs, and help to move world towards a cleaner, safer, and affordable energy. Current Scenario of Renewable Energy in India: Over the years, renewable energy sector has emerged as a significant player in India especially affecting the power generation capacity. This supports the government’s agenda of sustainable development while becoming an integral part in meeting the nation’s energy needs. For past two years, the Indian Government has taken several initiatives such as introduction of the concept of solar parks, organizing RE-Invest || JULY 2022 ||

Advantages of India:

Robust Demand: With the growing Indian economy, the electricity consumption is projected to reach 15,280 TWh by 2040. Increasing Investments: With Indian government’s ambitious targets, the sector has become quite attractive to foreign and Indian investors. It is expected to attract investments upto USD 80 billion (Euros 70 billion) in next four years. Competitive Advantage: Indian has sunlight available throughout the year and has a large hydropower potential. Renewable Energy Targets: The Indian Government has increased the target of renewable energy capacity to 175 GW by the year 2022 which includes 100 GW from solar, 60 GW from wind, 10 GW from bio-power and 5 GW from small hydro-power.

Different Renewable Energy Sources (RES)

Solar Power: Solar energy is a clean energy as it produces no harmful solid, liquid or gas wastes and does not create pollution. Solar power can be produced through PV cell which is made of semiconductor and Energy Collectors classified into parabolic trough, parabolic, tower and parabolic disc system etc. With 300 clear sunny days, India receives around 5,000 trillion KWh/year, which is far more than the total energy consumption of the country today. The solar power on the surface of the earth is 1016 W whereas the total worldwide power demand for all needs of civilization is 1013 W. Therefore, the sun gives us 1000 times more power than we actually need. Indian Prime Minister and the Prime Minister of France launched the International Solar Alliance. The ISA is an alliance of 121 solar rich countries and ISA aims to promote and develop solar power amongst its members and has the objective of mobilizing $1 Trillion (Euros 883 billion) of investment by 2030. Some large projects have been proposed by Indian government, and a 35,000 km2 (14,000 sq mi) area of the Thar Desert has been set aside for solar power projects, sufficient to generate 700 to 2,100 gigawatts. India is also the home to the world's first and only 100% solar powered airport, located at Cochin,

Kerala. India also has a wholly 100% solar powered railway station in Guwahati, Assam. Wind Power: Wind energy is turning out to be a very promising alternative energy technology of the future. Over the years, there has been considerable increase amount of energy produced by wind-driven turbines due to recent advancement in the turbine technologies. Although India is a relative newcomer to the wind industry compared with Denmark or the US, domestic policy support for wind power has led India to become the country with the fourth largest installed wind power capacity in the world. As of 30 June 2018, the installed capacity of wind power in India was 34,293 MW. Wind power accounts for 10% of India's total installed power capacity. India has set an ambitious target to generate 60,000 MW of electricity from wind power by 2022. MNRE announced a new wind-solar hybrid policy in May 2018 which means that the same piece of land will be used to house both wind farms and solar panels. Bio Energy: Biomass is a resource of renewable energy that is derived from carbonaceous waste of various human and natural activities. Bio energy encompasses biomass power, bagasse cogeneration, waste to energy, biomass gasifier, bio ethanol, bio diesel etc. Biomass takes carbon out of the atmosphere while it is growing, and returns it as it is burned. Given its tropical location and abundant sunshine and rains, India is an ideal environment for Biomass production. It is estimated that the potential for biomass energy in India includes 16,000 MW from biomass energy and a further 3,500 MW from bagasse cogeneration. Small Hydro Power (SHP): India is the 7th largest producer of hydroelectric power in the world. Hydro projects in India under 25MW capacity are classified as ‘Small Hydro Power’ and is considered as a ‘renewable energy’. SHP units with a total capacity of 4,380 MW have been installed up till now.

Government initiatives

Some initiatives by the Government of India to boost the Indian renewable energy sector are as follows: A new Hydropower policy for 2018-28 has been drafted for the growth of hydro projects in the country. The Government of India has announced plans to implement a US$ 238 million (Euros 210 million) National Mission on advanced ultra-supercritical technologies for cleaner coal utilization. The Ministry of New and Renewable Energy (MNRE) has decided to provide custom and excise duty benefits to the solar rooftop sector, which in turn will lower the cost of setting up as well as generate power, thus boosting growth.

Around 4.96 million household size biogas plants were installed in the country under the National Biogas and Manure Management Programme (NBMMP) by 2016-17. The Indian Railways is taking increased efforts through sustained energy efficient measures and maximum use of clean fuel to cut down emission level by 33 per cent by 2030.

Future Prospects of Renewable Energy in India:

With right investments in green technologies, we can say that India is well positioned to achieve the ambitious renewable energy targets. The pursuit towards cleaner energy will play a key role in supporting country’s transition to a full sustainable energy system. It is not a hidden fact that India is the world’s fourth-largest carbon emitter with its total population of 1.3 billion people with power sector contributing majorly to the same. However, in the recent years, India has made significant progress in field of renewable energy. Global climate change concerns have pushed the Government to develop a detailed plan for clean and sustainable power for all. As per the research by University of Technology (LUT) in Finland, owning to an abundance of renewable resources, there is a great potential for India to move into a fully renewable electricity system by 2050. This is possible if we can employ

||www.electricalmirror.net||

sophisticated technologies. Renewable energy’s development in India looks bright as around 293 global and domestic companies have committed to generate 266 GW of solar, wind, mini hydel and biomass-based power in India over the next decade. This would entail an investment of $310 billion - $350 billion (Euros 27 billion to Euros 30 billion). The International Finance Corporation, the investment arm of the World Bank Group, is planning to invest about $6 billion (Euros 5 billion) by 2022 in several sustainable and renewable energy programs in India. With the investment potential of INR 15 trillion (Euros 187 billion) over the next four to five years in Indian power sector indicates immense opportunities in power generation, distribution, transmission and equipment. Further, renewable energy storage market in India is also expected to witness robust growth, over the next decade, once the cost of storage declines, which is likely to happen because of sheer volume growth through the electric vehicle route.

Way Forward

To conclude, we can say that India has plenty of renewable energy to bridge the gap between demand and supply so we must persistently put in efforts to harness various forms of renewable energy sources with the use of newer technologies to form a clean and safe place for our coming generations. EM

FOCUS = PROFIT

Ramani Mani, Founder & Managing Director Modutec Ready Panels Pvt. Ltd.

||www.electricalmirror.net||

He appreciated the point and agreed that it makes a lot of sense for him to focus on the Electricals while outsourcing the Mechanicals! He prodded me to explain more. I went on to check if 80% of his Panels would align with a 2100mm height with the plinth extra. He said “Yes”. Then I said, lets simplify inventory carrying by further standardising on just 2 depths, 420mm and 600mm. And whenever you want a bigger depth just add on as 420+420 or 420+600 or 600+600 & even 600+600+420! The permutations again will take care of 80% of his requirement. He concurred. The only other element was the width which he could keep stock of about 5 variants which will again take care of 80% of his need; he smiled in appreciation. “And Modutec being a type tested, modular & flat pack design can be easily stored in a limited space in his factory”, I continued. With this approach, the Panel Builder is able to build IEC 61439 Type Tested Modutec Enclosures from his stock, Project wise, in record time! This Panel Builders’ eyes got wide with a eureka look and that’s when I moved in to recommend that instead of investing in fabrication machinery, he could opt to invest in Modutec stocks which would not only have a lesser outlay, but would release the bottleneck in his business and help him grow profitably with FOCUS as desired! And another option too can be explored, I added, of his being a Dealer for Modutec and helping his non-competing Panel Builders repeat the approach and help the world Simplify Panel Building! To conclude, Successful people have long realized that focus is the key to being productive. One must focus on what one wants in life and go after that 110%. Focusing on one thing at a time means getting more done. When a person is focused on something, they're paying attention to it. When a camera lens or your eyes are focused, they've made the adjustments needed to see clearly. And thus increase their Focus and consequently Profits. EM || JULY 2022 ||

A Panel Builder from Vishakhapatnam visited us at Modutec yesterday. He was curious to know what we do in Modular Switchboard Enclosure technology & we started off a soul to soul conversation. He told me that he had come for the Imtex exhibition in Bengaluru to explore buying machinery to augment his Panel fabrication. When I probed I realised that: o His annual turnover was Rs 12 Cr with an aim to hit Rs 20 Cr in 3 years. o He has basic fabrication infrastructure which is deployed to make his enclosures. o Powder coating was an outsourced activity. o The fabrication technology being adopted was welded & customised. o Fabrication was clearly his biggest constraint to scale. This Panel Builder is not alone. The willingness to look around for better technologies, would surely carry the potential, to deliver smarter & even safer & greener. But quite a number of us love to be that proverbial Frog in the Well, don’t we? Here’ s where I steered the conversation to. I requested him to consider the following: • What was his core competency, electrical or mechanical? He answered mostly electrical! • What was the Customer paying him for? Value addition to their electrical need majorly! • His Companys’ exposure to Digitalisation of their Switchboard? Infancy level he admitted. • To be profitable where should he focus? Mainly Electrical & Electronics popped out! • So, why was he putting his money in Mechanicals and getting Asset Heavy!!

Product Info

NEW CABLE AND PIPE LOCATOR SONEL LKZ-2000 – MOST ADVANCED PRODUCT! Companies dealing in power engineering, telecommunication or widely defined construction industry encounter many problems related to underground power cables or other utilities. Refineries, water and sewage management entities or repair companies need to know where their own or other cables are located, so as not to damage them during works. Sonel offers both widely used and renowned Sonel LKZ-1000 locators. Now we are introducing a new model of the cable and pipe locator – Sonel LKZ 2000. It is a more advanced and more powerful tool, which proves to be much more efficient in difficult cases, but remains easy to operate and assists the operator with hints on further actions.

Pic. 1. Sonel LKZ-2000 locator has a large, legible LCD display.

The locator’s receiver (LKO-2000) detects and tracks the routes of pipes, cables and other underground utilities conducting electricity. To guarantee a wide range of applications, it offers more than 70 frequencies and 4 operating modes (Power, Radio, Line, Probe). The central function is the noise measurement feature. The device scans the selected frequencies and indicates the ones which will be the most useful in the given location and rejects frequencies not recommended for the area. To increase localization efficiency, you should choose a frequency with the lowest noise possible. Visual and numerical noise level indications make it easier to select the right frequency. To allow for easier interpretation, the noise levels are displayed visually and numerically. The locator transmitter (LKN-2000) is designed to generate signals in the target object. The generated signals are detected by the receiver (LKO-2000). What is important is the possibility of setting the device up in such a way that the signal is emitted 142

at one of the 70 defined frequencies. The high power output function is another usable solution. It allows a 12 W signal to be transmitted along an active line at a frequency of no more than 10 kHz. For example, this function is used to locate buried largediameter steel pipes and to perform long distance locates. For instance, it is estimated that if a Æ 300 mm iron pipe buried at a depth of 1.5 to 2 m, the device, with its transmitter/ receiver frequency set to 640 Hz, is able to efficiently identify the localization at a distance above 5 km. Increasing the frequency to 8 kHz will reduce the distance by more than 1 km, while further increase in the frequency to 33 kHz will enable the user to trace the pipe at a distance of approx. 1.5 km. Line and Radio modes are based on active signals. It must be emphasized that active signals are placed on the target cable by the transmitter. The important features of the Line mode are: galvanic isolation, induction clamping and excitation induction. The line mode needs to be connected directly to the target line, and current is transmitted to the line in proximity of the transmitter. It should also be noted that in Radio mode, the signal is transmitted from an antenna located inside a non-metal tube. The power mode uses passive signals and allows the receiver to trace live power cables with voltage of 50 Hz or 60 Hz. The radio mode is also based on passive signals and enables the receiver to trace cables both receiving and emitting very low frequency (VLF) radio waves.

Pic. 2. The complete locator LKZ-2000 kit consists of the transmitter (LKN-2000) and the receiver (LKO-2000).

Receiver

The receiver operating in passive mode (Power) uses frequencies of 50 Hz, 100 Hz, 450Hz/60Hz, 120 Hz and 540 Hz. The passive mode (Radio) is based on frequencies from 15 kHz to 60 kHz. ||www.electricalmirror.net||

(8 kHz, 33kHz, “floating” version), transmitting cable\wound around a reel designed to locate non-metal installations, and the power supply unit with a transmitter battery pack. The use the BIK Probe allows for wireless cable identification.

Pic. 4. A-frame enables the location of the current leakage from a damaged underground cable.

Pic. 5. Sonel LKZ-2000 locator can be additionally equipped with 30-, 50- or 80 m-long transmitting cable.

Summary

Pic. 3. Sonel LKZ-2000 locator in operation.

Transmitter

The Sonel LKZ-2000 complete cable and pipe locator kit also includes a transmitter operating at frequencies of 512 Hz, 3140 Hz, 8192 Hz, 32768 Hz, 83.1 kHz and 20 kHz. The power output has 5 levels, and the maximum power in the induction mode is 3 W. With galvanic isolation, the power reaches 12 W, assuming the impedance of the connected object is 100 Ω.

Additional accessories

The cable and pipe locator Sonel LKZ-2000 can also be equipped with 5” clamps, A-frame (to locate the current leakage from a damaged underground cable ), NAD-1 transmitter probe

When reviewing the Sonel LKZ-2000 locator, you should pay special attention to the possibility of selecting a suitable localization mode. The distinctive feature of this model distinguishing it among other devices available on the market, is the ability to analyze noises on the jobsite. As a result, the most effective frequency, adapted to ambient conditions on the jobsite, is selected. You can avoid ineffective frequencies, thus making the localization much quicker and more effective. The remote control of the transmitter from the receiver menu highly improves work comfort and makes the entire operation shorter. It must be emphasized that lower frequencies have a longer range than the higher ones. In turn, high frequencies more easily interact with lines, but can also interact with lines other than the target one. EM

w w w. s o n e l . c o m

The active mode with a transmitter offering frequencies of 512 Hz, 3140 Hz, 8192 Hz, 32768 Hz and 83.1 kHz plays a key role. Antenna configuration is based on single peak value, double peak, null and full field. In the Power mode, the measured depth range is up to 3 m, and in the Radio mode – up to 2 m. In the active mode with a transmitter, the depth measurement range is 4.6 m, and in probe mode – even 6 m. It is also worth noting the accuracy of measurements. The measurement error does not exceed 5% of the depth in Line or Probe mode (from 0.2 m to 4.6 m) and 10% of the depth in Probe mode with a measurement at the depth of 4.6 m to 6 m. Due to the use of Bluetooth communication interface, the transmitter can be controlled remotely. An auto-turn off function has also been provided. The locator can work in temperatures from 20°C to 50°C. It can also operate at an angle, which allows detection to be performed under an obstacle such as parked car or a building. The receiver is operated with keyboard buttons which perform a number of functions, depending on the selected operating mode.
