SYSTEM AND METHOD FOR DYNAMIC GROUND FAULT DETECTION

摘要

A ground fault detector (206) includes a relay (302) configured to receive a first current. The ground fault detector also includes a voltage regulator (306) configured to provide a voltage potential to ground. The ground fault detector further includes an amplifier (308) configured, in response to a ground current flowing into or out of the ground fault detector, to change an output voltage of the amplifier in order to cause a change in the first current received at the relay. The change in the first current is indicative of a ground fault. Upon detection of a ground fault, the ground fault detector can be isolated from ground.
