The aging problem of material of composite insulators is one of key issues for power utilities. The most commonly used methods for aging evaluation are observation method, HC water spray classification method and static contact angle method and so on. However, there some subjective factor would be introduced by the operator of those methods. In order to investigate the aging state more objective,...
With an increase in usage amount and operating years of composite insulators, their failures caused by aging increased in number. The 110kV composite insulators in service were studied in this paper, and the electric field distribution along the axial direction of the insulator was calculated by using ANSYS software, which is based on the finite element method (FEM). According to the simulated results,...
