摘要：
This paper is aimed at the determination of the leakage current and the flashover voltage of discontinuously polluted insulators submitted to ac voltages, using a predictive dynamic model based on an equivalent electrical network. This model is an extension of the one we developed for uniformly polluted insulators. The influence of the width and conductivity of polluted layers is investigated. The simulated results are validated experimentally on a plane insulator model using electrolytic solutions of different conductivities.
