Abstract: Timely detection of insulator surface filth degree and timely measures can reduce the accidents of pollution flashover. Introduction was made to the electric quantity monitoring methods including leakage current method, equivalent salt density method, surface filth layer conductivity method, pollution flashover 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 monitoring method, and analysis was made to their advantages and disadvantages. Insulators turned up pollution flashover because of temperature,humidity, operational voltage etc synthetical factors. It is pointed out that the monitoring research direction of insulator filth degree should build up synthetic monitoring methods of comprehensive factors and parameters.
         Key words: insulator; filth; electric quantity monitoring method; non-electric quantity monitoring method
