摘要：

Dry air has been introduced to gas-insulated switchgears as an environmentally-friendly insulation medium for SF6 gas. Since its insulation strength is about one-third of SF6 gas, to grasp the insulation properties of highly pressurized dry air is necessary to apply dry air insulation to further high voltage equipments. In this paper, to consider smaller products and higher voltage ratings, insulation properties in highly pressurized dry air was investigated. Especially, pressure dependence, surface roughness dependence and the effect of surface processes were investigated.
