ABSTRACT:
In a power distribution system, power line insulators have three electrodes, two of which are connected to the line and to ground, and the third of which forms a capacitively stepped down voltage corresponding to the line voltage, and use sensing coils to measure current. The sensing coils are inversely connected and differentially located to suppress noise.
