Home / What signals are used in relay protection equipment
In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. An electrically operated switch like a relay plays a key role in controlling an electrical circuit through an independent low-power signal, otherwise used where a number of circuits should be controlled through the single signal.
