5. Equipment and Safety Grounding. Equipment grounding is a safety measure to prevent electric shock. It provides a low-resistance path for fault currents to flow into the ground in case of a fault or equipment failure, minimizing the risk of electric shock to individuals who come in contact with the equipment.
The risk of electric shock can arise in faulted electrical systems when exposed conductive segments become ''live''. To mitigate this risk, these segments need an effective earthing and fault detection protection system that can quickly resolve the fault before public or livestock are affected [ 10 ].
