A Ground Fault Relay (GFR) is a crucial protective device widely used in electrical systems to detect and safeguard against ground faults, preventing electrical accidents and potential damage to equipment. Ground faults can occur when current inadvertently flows through the earth or other unintended conductive paths, often caused by wiring errors, insulation failures, or equipment malfunctions. Without proper protection, these faults can lead to equipment damage, electrical fires, or even serious injury. In this article, we will delve into the workings, applications, and importance of Ground Fault Relays in maintaining electrical safety.
