What is the Main Function of Protection Relays? A voltage protection relay system is a necessary component of any electrical setup. 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. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.
