  • High voltage indication system
    Patent number: 8009055
    Abstract: Systems and methods are disclosed for detecting and indicating high-voltage presences on a machine. In one embodiment a high-voltage indication system is disclosed and may include a voltage detector configured to compare the voltage level associated with an element with a threshold voltage value, and provide an indication signal when the voltage level associated with the element is greater than the threshold voltage value. The system may also include an indicator powered by a separate power source independent from the voltage detector. The indicator may be configured to detect the indication signal provided by the voltage detector, and provide one or more warning signals in response to the indication signal.
