Influence of Pollution Degree and Humidity on the Discharge Characteristics of Porcelain Insulators in Fog Chamber Environment

Abstract

Abstract In order to study the influence of pollution degree and humidity on the discharge characteristics of porcelain insulators in a fog room environment, this paper uses Comsol Multiphysics software to simulate the electric field distribution of clean and dirty insulators in a 110kV transmission line with or without a fog room. The results show that the electric field around the clean insulator in the foggy room becomes larger at the high-voltage side and the low-voltage side becomes smaller than that in the non-fog room; and the electric field around the insulator in the fog room becomes larger as the contamination increases.
