Surface charge decay under the influence of prior applied voltagein freon

摘要

The application of high voltage to an insulating spacer causes ageneration of charges within and on the insulator. These charges distortthe electric field and may result in a significant modification of thewithstand voltage. The decay of the charge density subsequent to removalof the applied voltage is reported. At a fixed pressure the rate ofcharge decay increased with increasing pre-applied voltage. At a fixedpre-applied voltage, the rate of charge decay increased with increasinggas pressure
