  • On-line detection of partial discharge in electrical power systems
    Publication number: 20040263179
    Abstract: A method and apparatus for on-line detection of partial discharge events in an a.c. power system, in which high frequency electromagnetic pulses generated by partial discharge events are detected and analyzed in the frequency domain and the time domain to determine the type and location of the partial discharge event. The phase relationship between the partial discharge events and the on-line power signal is also examined to help indicate severity of the insulation anomaly giving rise to the partial discharge events.
