This paper discusses the relation between a breakdown stress and the polarity of accumulated charges on the surface of truncated conical spacers under the application of a DC voltage. In the present experiment, the polarity effects of the DC surface breakdown stress in vacuum are examined for various contact angles of the conical spacers making contact with the parallel plate electrodes. It is proposed that the accumulated charges on the surface of the truncated conical spacers will affect the DC surface breakdown stress, and these charges will depend on the contact angles. For confirming this mechanism, the electric fields around the conical spacer are visually analyzed to clear the effect of accumulated charges on the DC surface breakdown characteristics by the use of fluid flow mapper equipments.
