Movement Patterns of Metallic Particles in a Single Phase Compressed Gas Insulated Busduct with Electromagnetic Field Effect

Abstract—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.

Index Terms—Metallic particles, electromagnetic field effect, gas insulated busduct, gas insulated substation.
