How often is relay protection annual calibration required

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. Environment, load cycles, and operating conditions dictate recalibration frequency. Protection Relay Calibration required once in 2 years, by law – All electrical panels and switchboards have protection relays called earth fault and over-current relays which must trip the power supply in the event a. For reliable service of protective relaying excellent maintenance is a must. Setting determines pick-up value/time. Tests are conducted by the. Calibration and testing of protective relays require a systematic approach, incorporating both manual procedures and advanced automation techniques. Engineers in this field must familiarize themselves with detailed testing protocols, understand the implications of even slight deviations, and work. Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring.
