The function of relay protection energizer

When a system fault operates the protective relay, its output contact closes to energize the circuit breaker trip coil 52T, which functions to open the breaker main contacts and de-energize the connected power circuit. They help isolate faulted equipment quickly enough to reduce damage, maintain system. 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. It covers the protection methods for generators, transformers, buses, and transmission lines using various relay types to detect and isolate faults efficiently.
