Earthing plays an important role in the reliability of electrical power systemsAs it helps in ensuring the stability of the voltage level , it is common practice to connect the system to ground at suitable pointsSuch a connection will absorb sufficient current in the event of faultMaintaining variation in the ground grid resistance (Rg) within extremely tight limits is of utmost importance , as substantial variation leads to a potentially large variation in the ground step - voltage in the proximity of operational equipment , and could also increase the touch voltage on the equipment casing
