Earthing For Safety
Provision of adequate grounding in a substation and switching stations are very important for the safety of operating personnel as well electrical devices do not rise above tolerable thresholds and that the earth connection is rugged to dissipate the fault to the earth.
The importance of an effective, durable and a dependable earth for ensuring safety from electrical hazards does not require to be elaborated upon more.
By earthing, connecting the electrical equipment to the general mass of the earth, this has a very low resistance.
Requirements Of a Good Substation Earthing
The object of an earthing system in a substation is to provide under and around the substation a surface that shall be at a uniform potential and near zero or absolute earth potential as possible.
The provision of such a surface of uniform potential under and around the substation ensure that no human being in the substation subject in shock of injury on the occurrence of a short circuit or development of other abnormal conditions in the equipment installed in the yard.

The primary requirements of a good earthing system in a substation are:
1. It stabilizes circuit potentials with respect to ground and limits the overall potential rise.
2. It protects life and property from overvoltage.
3. It provides low impedance path to fault currents to ensure prompt and consistent operation of protective devices during ground faults.
4. It keeps the maximum voltage gradient along the surface inside and around the substation within safe limits during a ground fault.
Maximum Permissible Resistance Of Earthing System
Large power station 0.5 ohms
Major sub-station 1.0 ohms
Small sub-station 2.0 ohms
In all other cases 8.0 ohms
The earth continuity inside an installation 1.0 ohms
