Flashover behaviour of silicone rubber insulators were analysed under contaminated conditions in this paper. The modified IEC 60507 Standard was used to simulate pollution deposition on the insulator surface. Experiments were carried out at different pollution level and changing leakage distances to investigate the behaviour of silicone rubber insulators. It was shown experimentally that flashover voltage is highly dependent on pollution level and leakage distance. The result of this study can be used to investigate the ageing of silicone rubber insulators and their selection for contaminated and wet environments.
