Abstract: The mechanism of moisture absorption by an insulator surface contaminated with different salts was described. A list of some salts depending on their hygroscopicity was given. Measurements of surface conductivity and leakage current on flat insulator models at different relative humidities and with different types of salt were carried out. At natural atmospheric conditions the flashover voltage of cap and pin insulators subjected to 250/2500 ps switching impulses was evaluated.

Keyword(s): surface conductivity ; humidity ; hygroscopic properties
