Electric field calculation for an axially-symmetric insulator with surface contamination

The classical method of integral equations was applied to determine the electrostatic field distribution on an insulator coated with a thin homogeneous surface layer. Results of calculations of the electric potential and the electric field on both uniformly and nonuniformly polluted model insulators coated with layers of different surface conductivities are presented in this paper. An application of this method to the determination of distribution of the electrostatic field on a polluted longrod insulator has been demonstrated.<
