In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.: 4 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.
