Abstract

Abstract

In this paper, an experimental investigation on pseudospark discharge behaviors was conducted under nanosecond pulse using a flexible discharge chamber. The influences of gas pressure, anode-cathode gap distance and hole diameter on the breakdown voltages were studied. The study results showed that the breakdown voltage decreased with the increasing of the pressure, gap distances and the hole diameter. In the end, an empirical formula was obtained. The attenuation coefficients were 0.76, 0.39 and 0.39, respectively.
