Earthing Design

Author : Mr.Appavoo
Former CEIG / Tamil Nadu Electrical Inspectorate
Earthing provides a low impedance earth fault return path in order to ensure proper clearing of faults thereby limiting hazardous voltage and restriking which in turn reduces the risk of fires and personnel injuries
