110 (4), ER (Electricity Regulations) 1994; any protective relay and device of an installation will need to be checked, tested and calibrated by a competent person at least once every two years, or at any time as directed by the Energy Commission. Why is protective relay testing. Settings of various relays need co-ordination. Tests are conducted by the manufacturer at manufacturer s works, and by the user at site during commissioning and periodic maintenance. Many operators carry out secondary injection annually to ensure relays that protect circuits against overloads or faults operate appropriately. If applicable, documentation is required detailing how verified protection segments overlap to ensure there is not a gap. A relay may only need to operate for a fraction of a second in its decades-long life, but that moment can prevent extensive damage, prolonged outages, and worker injury.
