Abstract: Introduction was made to the application situation of ultraviolet test, infrared thermography test etc live test technologies and leakage current online monitoring test technology in live water washing process of substation equipment. Via comparison of ultraviolet image, infrared thermal image and leakage current measured values, this paper analyzed the safety and validity of live water washing technology of substation equipment. Application result shows that using live test and online monitoring technologies can realize whole journey online monitoring of live water washing and detect the external insulation state of equipment being washed in real time. This paper suggested popularizing application of such test technical means in live water washing process of substation equipment.
Key words: substation equipment; live water washing; online monitoring; live detection; ultraviolet detection; infrared thermography test;
