The Effect of the Surface Tension of Contaminants on Tracking Ageing of Polymeric Composites
오손액의 표면장력이 폴리머 복합재의 트래킹 열화에 미치는 영향
Abstract
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.
