This paper presents the investigation results of the effect of the core diameter on the flashover voltage of cylindrical polymer insulators under contaminated and heavy fog conditions. The specimens had the same or very similar shed profiles but diff

Hydrophobic polymer insulators show higher contamination flashover voltages compared with ceramic insulators, but standard artificial contamination test methods have not yet been established. Test methods used for ceramic insulators are now usually u

Superior insulation performance of semi-conducting glaze porcelain insulators under contaminated and wet conditions is attributable mainly to its drying effect by the leakage current flowing in the glaze. Contamination flashover voltages of semi-cond

Superior contamination flashover voltage performance of polymer insulators for transmission or distribution line is attributable not only to the hydrophobicity of silicone rubber housing material but also to their configurations. In the case of trans

Higher flashover voltages of transmission line polymer insulators were found to be due to large ratio of shed to trunk diameter. This causes current density at the trunks to be very high and all the trunks get dried causing the applied voltage to the

Wetting conditions specified for conventional porcelain and glass insulators are not severe enough for the evaluation of contamination flashover voltage performance of hydrophobic polymer insulators. They give lower flashover voltages under heavier f
