Ground Fault Relay (GFR) plays a critical role in ensuring the safety and stability of electrical systems. These devices are specifically designed to detect ground faults and protect both electrical equipment and personnel from the dangers associated with electrical faults. In this article, we will explore the function, operation, and significance of Ground Fault Relays, as well as their various applications across different industries.

What is a Ground Fault Relay? A Ground Fault Relay is an electrical protection device used to detect ground faults in an electrical system. A ground fault occurs when an unintended connection between a live conductor and the earth (or ground) happens, causing leakage current to flow through the ground. If undetected, this can lead to severe damage to equipment, fire hazards, or even electric shocks to individuals. The Ground Fault Relay monitors the flow of current and detects any imbalance or leakage to the ground, triggering an alarm or disconnecting the faulty circuit to prevent further damage.
