The present paper investigated surface conductivity and flashover voltage of cylindrical atmospheric and ordinary ice samples. The influence of the surrounding air temperature and the conductivity of freezing water on maximum withstand voltage and surface conductivity of ice samples was studied. The variations in temperature within the bulk-ice, an outer and inner ice surface, caused by the variations in surrounding air temperature were also examined. The results obtained will lay a foundation for establishing a future mathematical model for the criteria of flashover on ice-covered insulators.
