  • Discharge detection system for determining the distance to a dielectric weak point in a cable
    Patent number: 4013948
    Abstract: The distance from the end of the cable to the dielectric weak point of said cable is measured by applying a D.C. high voltage to said cable and generating a discharge at the dielectric weak point, obtaining a pair of pulse signals one by differentiating a surge signal generated and the other reflected at said dielectric weak point, limiting the amplitude of said pair of pulse signals, and measuring the interval between said pair of pulse signals.
