A Ground Fault Protection Relay is a protective device used in electrical systems to detect ground faults. Ground faults occur when an electrical current unintentionally flows to the earth, usually due to a breakdown in insulation or a conductive path from a live conductor to the ground. This can result in unsafe conditions, potentially damaging sensitive equipment or causing electrocution. The GFPR’s role is to continuously monitor the electrical system for these types of faults and trigger protective actions like alarming or disconnecting power, thus preventing further damage or safety hazards.
