Spectrum Measurement of Surface Flashover under High Voltage Nanosecond Pulse

摘要

Surface flashover is the key limitation of the performance of high power devices, so the study on surface flashover of insulating material is very important. This paper studies the spectral characteristic of vacuum surface flashover of epoxy material and tries to find the relationship of the flashover spectrum and some influence factors. And a spectrum testing system is set up for the measurement.
