Earthing System
The process of transferring the immediate discharge of the electrical energy directly to the earth by the help of the low resistance wire is known as the electrical earthing. It is a very vital part of any electrical system for the safety of equipments & human. it is meant for fast dispersion of lightning or any fault current safely & efficiently. A good earthing must have low electrical resistance between earth electrode & earth. It must be corrosion resistant & Environment Friendly.
