Abstract

Gas Insulated Substation has been more credible than Air Insulated Substation thus increasing its application in the electrical industry. Though being more advantageous there are some areas in the system where there is a need for study. Metallic particle contamination is one of the areas where there are chances for the risk or failure; the particles reduce the dielectric strength of the insulating medium i.e. the SF6 gas. The metallic particles can be formed from the enclosure, conductor or the insulating material during various operations such as assembling, operating, and transporting etc. The particles can exist anywhere on the enclosure, conductor and the spacer. In this paper a single phase Gas Insulated Busduct with conductor diameter of 55mm and outer enclosure of diameter 152 mm with a spacer inclined at an angle of 450 to the enclosure is considered.  Movement of aluminum and copper particles are studied which are present on the spacer at a certain distance from the enclosure
