Timely detection of insulator surface iflth degree and timely measures can reduce the accidents of pollution lfashover. Intro-duction was made to the electric quantity monitoring methods including leakage current method, equivalent salt density method, surface iflth layer conductivity method, pollution lfashover voltage gradient method and pulse current method, together with the non-electric quantity monitoring methods such as microwave radiation method, acoustic emission monitoring method and infrared imaging monitor-ing method, and analysis was made to their advantages and disadvantages. Insulators turned up pollution lfashover because of tempera-ture, humidity, operational voltage etc synthetical factors. It is pointed out that the monitoring research direction of insulator iflth degree should build up synthetic monitoring methods of comprehensive factors and parameters.
