Abstract :
In order to discuss the dielectric performance of
DC GIS, the flashover characteristics of gas-insulated bus were
studied under conical- and disk-type spacers. The test involves
the investigation on effect of electrification for charge to be
accumulated in spacers and the effect of metallic particles. As
the result, it was found that the dielectric characteristics of
conical-type spacer are better than disk type. Moreover, the
dielectric performance of DC GIS is more affected by the
characteristics of coaxial electrode system than spacer surface
with regard to metallic particle. On the basis of the results of
these tests, this report presents the conception of insulation
design for DC GIs.
