Analysis of Natural Pollution Deposit on Optic Sensor for Monitoring of Insulator Contamination

This paper describes a system for the online monitoring of insulators contamination, the system monitors equivalent salt deposit density near insulators on the power system by using optical technology. This paper mainly analyzes contamination components on optical sensor surface of different pollution sources coming from 17 sites in Sichuan, the inland areas of China, and draws the conclusion that calcium sulfate of industrial sources is more than ones of agricultural sources.
