Abstract

Abstract

High gradient insulator(HGI) structures assembled from alternating layers of metal and dielectric can result in improved performance of flashover compared to conventional insulators as they can restrain the process of vacuum flashover. Samples which are constituted of different materials and processed by different preparations have huge difference in surface breakdown field strength. Performance of flashover of the samples with different materials and different sizes were tested, and the influence factors of sample surface flashover field strength was analyzed with the surface micrographs.
