Abstract :
In this paper, we investigated the surface flashover characteristics under the existence of surface charge on alumina ceramic insulator in vacuum. We investigated the surface flashover voltage with varying the location and magnitude of surface charge. We discussed the surface flashover mechanisms under the existence fo the surface charges of alumina dielectrics in vacuum.
