A study of the particle movement in diverging electrodes under DC voltage in GIS

The paper presents a computer oriented analysis and procedure for computation of dynamic motion of free conducting particles in electric fields between diverging conducting plates with high voltage DC in GIs. Non-linear dynamic equations of the spherical particle motion was estimated numerically by using Rung Kutta method and graphically visualized. It was found that when the particle is placed on the horizontal electrode surface, the particle progresses towardes a higher electric field region by the effect of coulomb force and electrical gradiant force. This study includes the influence of the most important design parameters on the particle motion, such as applied voltage magnitude, particle density and dimensions, initial particle position and plate angle.
