Abstract

a compensating reactor in a coupling capacitor potential device including a magnetic core with an inductive winding, the reactor providing inductive reactance cancelling capacitive reactance of the device, and a voltage limiting device connected across the compensating reactor which is a ceramic oxide non linear resistor. The reactor core can be a magnetic steel whose normal saturation level substantially exceeds the voltage at which the voltage limiter changes resistance.
