Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. Grounding is necessary to assure correct operation of electrical devices, to assure safety. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. This helps to reduce the potential difference that exists between conductive parts and the earth. The system grounding arrangement is determined by the. That's why today we'll break down the life-or-death details of grounding distribution boxes and cable shielding layers using plain language. No textbook fluff – just what actually works in the real world. Next, we describe directional elements suitable to provide ground fault protection in solidly- and low-impedance grounded.
