Pulse Discharge Characteristics of Composite Electrode Systems

Abstract

This paper describes the rectangular pulse discharge characteristics of the composite electrodes in N₂ gas. A glass or ZnO contacts with the needle for the needle-plane electrodes configuration. In the case of the glass contacted with the needle, the discharge voltage increased with increasing L (the distance from the tip of a needle to the dielectric). In the case of ZnO contacted with the needle, the discharge voltage increased with increasing L from 0mm to 2mm, but it gradually decreased with increasing L from 2mm to 10mm. It is considered that these differences on the discharge voltage characteristics originate from the corona extension process and discharge path.
