| Abstract |
When faults occur in the power equipment that is used a great deal in industrial sites, it may lead to fatal accidents that cause losses both economically and in manpower, In this paper, the effect of particle impact on the partial discharge of SF? gas was measured by simulating a partial discharge following the type of fault found in the GIS using SF? insulating gas as the insulating material. A spectrum analysis was performed on the radiate electromagnetic waves emitted upon partial discharge by using the UHF insulation diagnosis method. This subject of this study is insulation diagnosis by the measurement of radiate electromagnetic waves when particles exist in the GIS and power equipment insulated with SF? gas. |
