Surface resistance modified electric field computation in asymmetric configuration using surface charge simulation method: a new approach

A novel formulation has been proposed in this paper for the calculation of asymmetric electric field including surface resistance using Surface Charge Simulation Method (SCSM). The formulation has been tested for a partly conducting dielectric sphere placed in uniform sinusoidal field and also for an axi-symmetric post type insulator. Finally the method has been applied for computing the effects of resistivity on the field around the solid components of high voltage metal enclosed equipments having asymmetric geometries. The effects of surface resistivity on the field distribution for different examples have been reported in details. The results are in good agreement with those reported in previous literature for axi-symmetric insulator. For asymmetric spacers the results highlight the locations of field enhancement, which is practically significant for compact gas insulated systems.
