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.

A Complete Guide to Protective Relays and Their Role in Power

A protective relay operates by continuously monitoring electrical parameters, detecting abnormalities, making decisions, and triggering circuit breakers to isolate faulty sections.
