WebElectrical Grounding is defined as the process of transferring the immediate discharge of electricity directly to the Earth with the help of a low-resistance wire. Electrical grounding was invented as a safety system to help prevent people and equipment from accidentally coming in contact with electrical hazards. WebMar 1, 2000 · The loop impedance is the sum of all impedances in the faulted circuit, including the supply transformer, the ungrounded conductors, and the grounding circuit. For example, a loop impedance of 1 ohm on a 120-V circuit would allow 120 amp to flow, causing the circuit protector to trip very rapidly.
