Abstract

In order to study the effect of pollution un-uniform distribution on insulation performance of outdoor insulators, in the paper, the size of the dirt layer conductivity is used to describe the pollution extent of insulators and then the three-dimension harmonic quasi-static electric field of XP-160 insulators under pollution un-uniform distribution is calculated. The effects of different conductivity of dirt layers and several typical pollution un-uniform distributions to the electric field distribution along the surface of insulators are investigated. Comparing the leakage current obtained from artificial contamination test with the results of calculation, the reliability of the model is verified.
