Relay Calibration & Circuit Breaker Servicing
A protective device (relay & breaker) is very crucial to be checked, tested, maintained and calibrated regularly by a competent person. If the protective devices are not monitored or measured properly, they can cause malfunction, false tripping, or non-tripping. With proper maintenance, these protective devices can last for decades.
