| Abstract: | The surface discharge models that can simulate the electrode configuration of the wall bushing and the post-type insulator are established.With this model the influence of the electrode configuration,interpolar distance,surface conductivity and the polarity of the applied voltage on the flashover voltage along the surface is investigated.The reason which causes the differences of the flashover characteristics between two electrodes is analyzed. |

| Keywords: | surface conductivity flashover characteristic lightning impulse voltage HVDC wall bushing post-type insulator |
