A transformer is a heart of power system and this heart should beat till it’s useful life for feeding all kinds of load requirement of all types of consumers/products without any interruption.

Despite being a very simple and robust device, transformer gets failed well before there useful life or we can say die a premature death in most of the cases.

Reasons for failure are not one or two, but many, under the following category, (a) Quality, (b) Installation & Commissioning, (c) Protection, (d) Operation & Maintenance, (e) Condition Monitoring, (f) Lack of Know how & skills of people, (g) Theft cases, (h) Age etc.

In our country barring few private utilities where the failure rate of overall power and distribution transformers are less than 1 %, the failure rate of transformers is very very high elsewhere.

Apart from the life of transformers, other challenges utilities faces are, (a) Lesser footprint, (b) Environment-friendly, (c) Zero Fire Hazard, (d) Low on maintenance, (e) Low losses and High Efficiency,  (f) Usage /Scrapping of Old defective stock of transformers.

HT and LT  switchgear are vital equipment in Electrical network in the power system. They are protection device used to make and break the circuit as and when required and most important is to isolate the faulty circuit in time in any type of fault condition.

Despite being highly reliable & safe equipment,  they get failed/malfunction well before there useful life or we can say die a premature death in most of the cases.

Reasons of failure are not one or two, but many, under the following category, (a) Installation & Commissioning, (b)Operation &Maintenance, (c) Condition Monitoring, (d) Lack of Know how & skills of people, (g)Theft cases etc.

In our country barring few private utilities where failure rate /malfunctioning of circuit breakers are less than 1 % , failure rate/malfunctioning of circuit breakers is very very high elsewhere.

Apart from the life of circuit breakers, other challenges utilities faces are, (a) Utilization of protection system properly, (b) Updation of protection system with latest technology, (c) Proper utilization of all accessories of RMU/Circuit breakers (d) Gas leakage from SF6 RMU, (e) Usage /Scrapping of Old defective RMU/Circuit breaker.

Power distribution is the most crucial link in the electricity supply chain and has a great significance in respect to impact on the sector’s commercial viability, and ultimately on the consumers who pay for power services.

The distribution system continues to carry electricity from the point where transmission leaves off, that is, at the 66/33 kV level.

Depending upon the quantum of power and the distance involved, lines of appropriate voltages are laid.

The main distribution equipment comprises HT and LT lines, transformers, substations, switchgear, capacitors, conductors and meters.

HT lines supply electricity to industrial consumers while LT lines carry it to residential and commercial consumers.

Energy is one of the most important components of economic infrastructure. It is the basic input required to sustain economic growth.

As of 31st  July 2018, following is the share of sources of energy in India.

Thermal ( Coal, Gas, Diesel) –  222.6 GW ( 64.3% ), Renewable – 71.51 GW (20.6 %) ,  Hydro – 45.3 GW( 13.1 % ), Nuclear –  6.8 GW (2%)

Total installed power capacity of India is 346.02 GW and Renewal energy potential is >1000 GW ( Solar 750 GW, Wind 300 GW, Bio 25 GW, Small Hydro 15 GW)

Coal, Nuclear, Gas & Diesel are non- renewable sources, with harmful emissions and going to exhaust by this century.

Hence Solar, Wind, Tidal, Bio which are renewable sources of energy are the solution for the future and their growth and development is the need of the hour.

Our country having huge potential to generate safe and cheap energy by renewable sources is running one of the largest and most ambitious renewable capacity expansion programs in the world.

The total installed capacity of renewable energy as on 31^st July 2018 is 71.51 GW ( Solar 23.11 GW, Wind 34.40 GW, Bio 9.51 GW, Small Hydro 4.49 GW )

Renewal energy target by 2022 is  175 GW ( Solar 100 GW, Wind 60 GW, Bio 10 GW, Small Hydro 5 GW )

This shows the potential in the field of  Solar Energy

Out of 100 GW target for Solar energy, 40 GW is a target for Rooftop solar and till now only 2 GW has been achieved.

Solar Rooftop has great potential and can indeed be a game changer in attaining 100 GW of Solar Energy by 2022.

Electricity generated could be:
(a)used for self-consumption and surplus to grid with a net-metering approach

(b)fed into the grid at regulated feed-in tariffs

(c)Offers electricity consumers a lower electricity bill

Challenges in meeting targets of rooftop solar power plant are (a) Lack of awareness on advantage of  rooftop solar among owner (Residential, Institutional, Commercial, Industrial ), (b) Lack of awareness on government schemes/ policies on   rooftop solar among owner (Residential, Institutional, Commercial, Industrial ), (c) Small EPC companies without much know how/skill doing unproductive installations, damaging customer confidence,   (d) Cutthroat competition among small EPC companies shaking confidence of rooftop owner,  (e) Public utilities not giving prompt response /service to rooftop owner in case of net metering/Grid tie system.
