Abstract

The major threat to Gas insulated Bus duct is presence of metallic particle contamination in the form of loose particles. This may be present on the enclosure, HV conductor or on the spacer. In this paper conducting contaminant trajectory is obtained for particulate on the spacer with SF₆ gas dielectric medium. Wire like metallic contaminants of length 10mm with 0.25mm radius of copper, Aluminum and silver are considered to be present on the epoxy coated spacer in 1-Φ GIB with an inner conductor diameter 55mm and an outer enclosure diameter of 152mm.Results are obtained and analyzed for different typical 1-Φ GIS power frequency voltages.
