—Electrical insulation performance of compressed
gas insulated Substation is adversely affected by metallic
particle contaminants. Free conducting particles, depending
upon their shape, size and location, may lead to serious
deterioration of the dielectric strength of the system. The work
Presented in this paper analyses the movement pattern of
metallic particles in Gas Insulated Busduct (GIB) in the
presence of Electromagnetic field. In order to determine the
particle trajectories in a GIB, an inner diameter of 55 mm and
outer enclosure diameter of 152 mm were considered. The
movement pattern of metallic particles at different voltages of
Aluminum, Copper and Silver in a GIB has been simulated with
and without enclosure coating. Typical results shown that there
is a considerable increase in movement of the particle when
electromagnetic field effect on the particle is considered. This
particle movement is greatly reduced while considering
dielectric coating inside the surface of the enclosure.
