초록

In this paper, the effect of surface tension, wettability, flow rate of contaminants with varying surfactant content and frequency of applied voltage on the tracking breakdown of epoxy insulating materials were investigated. As the flow rate of contaminant is increased, the surface resistivity is decreased, and the leakage current is increased, the time to tracking breakdown is decreased. It is found that time to tracking breakdown depends on the surface tension of contaminant, that is difference of wettability And as the frequency of applied voltage is increased, time to tracking breakdown decreased.
