Potential Distribution Measurement of Back-discharge Phenomena by Using Electro-optic Effect

Abstract

The transient potential distribution on an insulating material with a surface discharge and a subsequent back-discharge is measured with high resolution of time and space by using Pockels sensing system. It is proved that a part of electrical charges, which are generated due to a surface dishcarge and accumulated near a high-potential electrode, flow back into the electrode with a subsequent back-discharge.
