1. A system for monitoring a partial discharge event in electrical power apparatus including a housing and a plurality of openings in said housing at spaced-apart locations through which electrical power may pass via electrical feedthroughs, said system comprising:

  • a plurality of electrical sensor means, each being in communication and associated with an electrical feedthrough at an opening, for simultaneously and synchronously sensing an electrical component of the partial discharge event at each of the plurality of openings and for producing sensor output signals;

    waveform capturing means electrically coupled to the sensor means for simultaneously and synchronously receiving said sensor output signals over an interval of time, and for producing simultaneous synchronous captured waveform signals; and

    processing means electrically coupled to the waveform capturing means for processing said simultaneous synchronous captured waveform signals.
