A comprehensive testing program should simulate fault and normal operating conditions of the relay. Modern networks rely on and utilize relay protection systems in order to maintain a safe electrical environment by continuously monitoring devices for problems and controlling the grid to isolate problematic areas. Since the basic function of a protection relay is to correctly function under abnormal. Its application covers the entire life cycle of the device, including research and development, production, acceptance, installation, commissioning, maintenance, and technical renovation.

The National Electrical Code (NEC) section 230-95 requires that ground-fault protection be applied ". This decreases the current at the fault and limits voltage across the arc at the fault to decrease damage. "Equipment grounding" means the connection of earth ground to non current carrying conductive materials such as conduit, cable trays, junction boxes, enclosures and motor frames. Ground-fault relays help protect people from injuries and prevent damage to electrical equipment.
