Abstract

We investigate the insulation properties of CO₂ gas in the presence of a metallic particle. CO₂ gas attracts attention as an alternative gas to SF₆ gas because of its relatively very small global warming coefficient gas and relatively good dielectric strength. To design CO₂ gas-insulated apparatus, the influence of a metallic particle on insulation properties has to be clarified. In this paper, we investigate the motion of a metallic particle and partial discharges in CO₂ and SF₆ gases by measuring acoustic and electromagnetic signals. As a result, it was found that a free metallic particle motion differs in CO₂ gas and SF₆ gas because of differences in partial discharge characteristics.
