  • Systems and methods for electrical leakage detection
    Patent number: 7459914
    Abstract: Systems and methods are disclosed for detecting balanced electrical leakage between a power source and a machine frame. In one embodiment, a balanced fault detection system for a machine includes a power source that is electrically insulated from a machine frame and a leakage detection switch that is connected to a ground. The balanced fault detection system also includes a leakage detection resistor that is interposed between a power source terminal and the switch having a leakage detection resistance. The balanced fault detection system further includes a voltage measuring device that measures voltages of the power source at positive and negative voltage sides of the ground and a leakage calculator that calculates a leakage resistance of the machine based on the measured voltages at the positive and negative voltage sides and the leakage detection resistance.
