| Abstract: | In some districts with severe air pollution,the flashover of insulators takes place frequently and threats the safety operation of power system.In order to realize real-time monitoring for the contamination state of insula-tors,this paper designed an ultraviolet monitoring system based on ultraviolet pulse method.Simulation tests were executed with this system on composite insulator FXBW-110 /70 and porcelain insulator XP-160 under different op-erating voltages and contamination levels with the presence of ... |
