1. A system for identifying an arcing event in electrical distribution equipment:

  • memory for storing an arcing radio frequency characteristic indicative of an arcing event generated in electrical distribution equipment and a noise radio frequency characteristic indicative of background electrical noise;

    a sensor for detecting radio frequency signals resulting from the arcing event and propagating wirelessly from the electrical distribution equipment;

    a processor for processing the radio frequency signals detected by the sensor to extract radio frequency characteristics from the detected signals and including a comparator for comparing the extracted frequency characteristics to the arcing radio frequency characteristic and the noise radio frequency characteristic stored in memory to identify occurrence of an arcing event; and

    an arc alarm generator for generating an arc fault signal indicative of the occurrence of the arcing event.
