Cylindrical post spacers were used to investigate the fundamental effect of ribs on particle initiated breakdown characteristics. Improved breakdown characteristics, obtained by attaching the ribs, changed with the distance between them. The shorter the distance was, the higher the breakdown voltage. When the distance was less than 20 to 30% of the spacer length, the breakdown voltage increased 20 to 60%. The rib effectiveness for SF/sub 6/ gas insulated switchgear spacers was demonstrated.
