Abstract
The pollution on the surface of an insulator is asymmetric, although insulators, in general, are axisymmetric. The distortion of fields on the surface of an asymmetrically polluted axisymmetric insulator is computed in this paper. The surface charge simulation method (SCSM) has been used with cylindrical, conical and toroidal surface elements. The volume resistivity of the insulation also has been taken into consideration, using complex permittivity for the insulating material
