Effect of Wetting Conditions on The Contamination Flashover Voltages of Polymer Insulators

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 fog conditions but a detailed comparison of their contamination performance under varied fog densities hasn't been made. In this paper we investigate contamination flashover performance of polymer insulators under varied fog densities
