Abstract
In a system for continuously monitoring partial discharge in high voltage electrical equipment thereby to give advance warning of impending breakdown of solid-insulated components, means are provided to distinguish electrical signals indicative of partial discharge from those resulting from noise or external transients. Current pulses in the various partial discharge paths are detected, and by solid-state circuitry their relative polarities are compared and an appropriate signal is made according to the comparison.
