Movement of metallic particle contamination in a gas insulated busduct under dielectric coated enclosure with electromagnetic field effect


The purpose of coating the inside surface of gas insulated busduct (GIB) enclosure with a dielectric material reduces the deleterious effect of electrode surface roughness, impedes the development of metallic particle initiated micro discharges, increases the field required to lift particles, and reduces the charge acquired by particles. The performance of particle contaminated compressed gas systems with dielectric coated electrodes are analyzed in this paper. The equations governing the motion of the particle due to its electromagnetic field effect has been formulated to obtain the particle trajectories. Hence simulation has been carried out to study the effect of fields on the motion of the particle with and without electromagnetic field effect under dielectric coated enclosure. Particle trajectories obtained for various voltages of aluminum, copper, and silver particles of size 12 mm in length and 0.2mm as radius present on the enclosure. The simulation results have been presented and analyzed.
