Systems and methods are disclosed for compensating electrical leakage and detecting balanced electrical leakage for a machine hosting an HV system. In one embodiment, a fault detection and compensation system includes a DC power supply electrically referenced to a machine frame, a leakage correction switch connected to the machine frame, a current source controlled by the leakage correction switch, and a voltage measuring device that measures an offset voltage reflecting whether the HV system is in an unbalanced fault condition. The fault detection and compensation system further includes a leakage detection and compensation controller that compensates for the unbalanced fault condition by controlling the leakage correction switch and the current source.
