Pollution flashover of insulator may seriously affect safe operation of power system and timely detection for degree of contamination of insulator is able to prevent accidents. Therefore, this paper introduces electric detector for contamina- ted insulator based on microwave radiation detection technology and locale detection for operational insulator with high volt- age electrification. It compares detection result with measuring results of corresponding equivalent salt deposit density and e- quivalent dust density. The preliminary testing and study result shows that this detection device for detecting contaminated insulator is applicable for detecting degree of contamination of high voltage electrified insulator.
