According to regulations such as Malaysia's Electricity Regulations 1994 (Regulation 110), all protective relays and associated devices must be checked, tested, and calibrated by a competent person at least once every two years or whenever directed by the relevant energy authority . This ensures that relays operate correctly during fault conditions, preventing equipment damage, prolonged downtime, and potential safety hazards .
Regular calibration maintains the accuracy and reliability of protective relays. It helps to:
Calibration typically involves:

Static Relays containing analog and digital discrete electronic components and small ICs similarly required testing and adjustments
Good Answer: If you mean the interval between test calibration events, that depends on several factors. The interval
In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.
Unlike the rotating machines or other equipment, the protective relays remain standstill and without operation until a fault develops.
