CAMTECH/99/E/EARTH/1.0 Earthing - Central Railway
Earthing eliminates the possibility of any dangerous potential rise on the body of an electrical equipment. It drains away the charge on the equipment body through an earth connection. When the equipment is earthed, a fault in the equipment, say, winding insulation failure causes a heavy current to flow into the general mass of the earth.
