Breaker Protection Relay is a device used to protect circuit breakers from damage caused by overcurrents or other electrical faults. The breaker protection relay works by monitoring the current and voltage levels in the circuit, and if it detects an excessive current or a fault condition, it will send a signal to trip the breaker and isolate the fault. These can also provide additional functions, such as fault location and event recording, allowing for more efficient troubleshooting and analysis of system performance. The Breaker Protection Relay is an essential component in ensuring the safe and reliable operation of electrical power systems, protecting both the equipment and personnel from harm due to faults in the system.
