SF6 is widely used in high-voltage equipment due to its excellent insulation ability. However, when the moisture content in SF6 exceeds a certain value, its insulation could be damaged, threatening the normal operation of high-voltage equipment. Therefore it's of great importance to establish proper control standards on moisture content in SF6. In this paper, the influence of moisture content on flashover...
The insulation capacity of electric power transformer will be affected by running in overheated conditions, and the winding hot spot temperature is the main limiting factor of transformer load, so the winding hot spot temperature should be measured accurately. Online temperature monitoring method using Fiber Bragg grating is presented in this paper. By the application of optical fiber grating temperature...
