WebThe earth must be treated as a semiconductor, while the grounding electrode itself is a pure conductor. These factors make the design of an earthing system complex, not derived from a simple calculation or the random driving of a few rods into the soil. Knowledge of the local soil conditions is mandatory and is the first step in the design process. WebThe design approach has to be conservative because of the aforementioned IG =Maximum grid current in K.A uncertainties. A good grounding system provides a low resistance to remote earth in order to minimize the ground potential rise. For most transmission and other large substations, the ground resistance is usually about 1 Ω or less.
