  • Arc detection
    Publication number: 20020118022
    Abstract: Signals representative of current and voltage in a circuit are processed and compared with stored temporal models models representative of arc faults and events not associated with arc faults. The models may be templates or stochastic models. Alternatively, the processed signals may be supplied to an artificial neural net programmed to recognize features of different arcs. An output may be provided to open a circuit breaker when an arc fault is detected.

  • Arc location
    Publication number: 20020053914
    Abstract: The current and voltage in an electrical system are monitored to detect an occurrence of an arc. The location of the arc is determined by propagating a pulse signal on the system in response to detection of the arc and timing the interval between reception of a portion of the signal reflected back from the location of the arc.
