| Abstract: | The volt-ampere characteristics of the arc developing along the surface of polluted insulator and the surface conductivity of remainder pollution layer were measured. The idea of effective surface conductivity v. was proposed and the method to determine it was presented. A new method to calculate the DC flashover criterion of polluted insulator was proposed. Experimental data of some insulators are in agreement with the calculated results. |
