Abstract: This paper describes a comparison between a polymer and porcelain insulator subjected to salt polluted condition. Exposure test at laboratory was carried according to IEC 60507 out and flashover behavior of insulators at different contamination level was observed. The insulators were manufactured with same profile of the electrodes and had the same number of sheds to get result which were easy to compare. The influence of the different salt contamination level was observed for both porcelain and polymer insulator and a comparison was made between both insulators on the basis of the effect of similar type of salt contamination level for both insulators. Porcelain insulator surface is less hydrophobic as compared to polymer insulator surface.
Keywords: Porcelain insulator, Polymer insulator, Flashover voltage, Contamination level, Flashover characte ristic.
