The insulators' pollution flashover will cause huge economic losses. But at present, there is no non-contact method with high accuracy to detect the pollution state of insulators. This paper aims to realize the non-contact online detection of the pollution state on the surface of the insulators, by researching on multi-source imaging methods, including visible imaging, infrared imaging and ultraviolet...
Flashover occurs more easily on contaminated insulators, which causes great economic losses and has bad effects on power system stability. A new method is introduced to discriminate the contamination grades of high voltage insulators, using information fusion of visible images and infrared images of the insulators. Firstly, three heating models of running insulators—No Dry Band, Dry Band and Dry Band...
Insulator is one of the most commonly used devices in transmission lines, so that the reliability of insulators is of great importance to the stable and safe operation of the electric grid. This paper analyzed the filthy discharge of polluted insulators based on ultraviolet (UV) imaging detection technology. By establishing an equivalent circuit model of polluted insulators, this paper analyzed and...
