Abstract
An improved control circuit for protecting a high voltage DC electrostatic system from arcing by removing the high voltage from the electrostatic system under incipient arcing conditions. A signal having a voltage proportional to the instantaneous high voltage current in the electrostatic system is established. DC components and unwanted noise and unwanted AC components are removed from the signal to leave only signal components relating to the rate of change of the current in the high voltage system and information indicative of incipient arcing conditions. When the remaining signal exceeds a predetermined reference level, high voltage is removed from the electrostatic system.
