What is a Protective Relay? Principle, Advantages,
A protective relay is an electrical component that is designed to trip a circuit breaker when a fault is encountered or identified.
Protective relay
OverviewOperation principlesTypes according to constructionRelays by functionsPower sourceIn electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, overvoltage, reverse power flow, over-frequency, and under-frequency.
