Abstract	SF/sub 6/ is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. A study of CIGRE group suggests that 20% of failure in GIS is due to the existence of various metallic contaminations in the form of loose particles. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields. If the effects of these particles could be eliminated, then this would improve the reliability of compressed gas insulated substation. It would also offer the possibility of operating at higher fields to affect a potential reduction in the GIS size with subsequent savings in the cost of manufacture and installation. The purpose of this paper is to develop techniques, which will formulate the basic equations that will govern the movement of metallic particles like aluminum, copper in a coated as well as uncoated busduct. However, the configuration at the tip of the particle is generally not sufficiently smooth enough to enable the movement unidirectional. This decides the movement of the particle in axial direction. The randomness of movement can be adequately simulated by Monte-Carlo Method. This method has been applied for coated as well as uncoated enclosure. The results have been presented for the above cases.
