Nowadays power supply system is to say AC electricity is generated, transmitted and distributed in the form of current alternative. The electrical power is produced at the level of the position of power, which are located at places favourable, generally away from consumers. It is delivered to the consumer through an extensive network of transport and distribution. To the number in the supply line, it may be desirable and necessary to change certain characteristics (for example voltage, current alternative current continuous frequency P.F. etc.) power. This is achieved by an appropriate device called a substation for example, generation voltage (11KV or 6.6 kV) power station is stepped up to high voltage (Say 220KV to 132KV) for the transmission of electrical energy. Similarly, close communities of consumption, the voltage can be strengthened to the level of use. This work is again directed by called suitable equipment substation. 2.1 about the substation: the position of Bhinmal, Jalore-343029, Rajasthan is one of the largest networks of electricity in the State of Rajasthan and the Northwest region of the India. The most important of any post is the grounding (SLT) of instruments, transformers, etc. used in the substation for the safety of operating personnel, as well as for the proper functioning of the system and the performance of the protective devices. A system of earthes comprising a grounding pad buried to a depth suitable basement and supplemented with rods of Earth at appropriate points are provided in the substations. This soil, very high voltage to ground. As it is dangerous for us to go near the instrument without proper grounding. If the instruments are not ground properly, they can give a huge shock for anyone to stay close to him and also it is dangerous for the expensive instrument, because they may be damaged by the high voltage.
