What Is a Ground Fault Relay?
A ground fault relay is a device connected to an electrical circuit that detects abnormal voltage and activates an alarm through the operation of a relay.
It operates in two basic modes: open mode and closed mode. In each mode, the relay is either open or closed under normal conditions. The operational principle involves detecting abnormal voltage, which then switches the relay contacts, activating the alarm function.
In open mode, the relay interrupts the current flow by being open under normal conditions and closes its contacts when an abnormality is detected, allowing current to flow. Similarly, in closed mode, the relay switches to an open state when an abnormality is detected, interrupting the current flow. This results in actions such as sounding an alarm or activating warning lights.
