Differential Relay: Compares currents at two points; operates when there is a difference (used in transformers and generators). What controls it: Relay performance depends on the protected zone, CT/PT inputs, pickup settings, time delay, breaker clearing time, trip. A protective relay is an intelligent electrical device designed to detect faults in power systems and initiate corrective actions such as tripping a circuit breaker. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to.
