Protective Relays: Types, Working Principle & Uses

What Is a Protective Relay? A protective relay is a control and measurement device used in power systems to detect faults, unsafe operating conditions, or abnormal electrical behavior.

OverviewOperation principlesTypes according to constructionRelays by functionsPower source

In 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.
