understanding ground fault relay： essential protection for electrical systems

A Ground Fault Relay (GFR) is a crucial protective device used in electrical systems to detect and manage ground faults, helping to prevent damage to equipment and reduce the risk of electrical hazards. Ground faults occur when electrical current unintentionally flows to the ground due to insulation failure, faulty wiring, or any abnormal contact between an electrical conductor and the earth. The purpose of a GFR is to monitor and react to these faults by triggering alarms or shutting down affected circuits, ensuring safety and preventing potential catastrophic consequences.
