【Abstract】 The research rasults in existence have indicated that the pollution flashover voltages of insulators decrease along with the increase of their surface conductance. Therefore,it has been becoming increasingly important to study surface conductance mechanisms in order to under stand the flashover phenomena of insulators. Taking the polluted glass sheet as experimental subuect, we have measured its surface conductance in a fog chamber and obtained a large nunber of experimental results. Through analyzing and summarizing the experimental data, we have gained useful conclusions which are helpful for monitoring insulation on-line, based on percolation theory, the surface conductance curves sinulated by software are in good agreement with the experimental results.更多还原
