1010603Substation Grounding
Background In the construction of alternating-current (AC) electrical substations, it has been a long-standing practice to install a grid of buried metal conductors over the entire substation yard and to solidly connect this grid to the neutral of the AC power system. The purpose of this buried grid is to make the substation yard a safe place even when a fault to ground occurs, and to provide a path of low impedance between the neutral of the power system and earth. A good connection between the neutral of the power system and earth is vital to maintain the voltage gradient between them as low as possible under all operating conditions. Good neutral grounding enha…
