A technique and system for detecting a location of a ground fault in an electrical system are provided. The technique and system include steps or components for determining a ground fault voltage, receiving a gate control signal associated with an electric load, comparing the ground fault voltage to the gate control signal, and determining whether the ground fault is located at the electric load based on the comparison of the ground fault voltage to the gate control signal.
