Authors: Ranuva Nageswararao and S.S. Tulasi Ram
Abstract: Gas Insulated Substations have to withstand for lightning and switching surges without breakdown of Insulation. In this paper a three Phase Gas Insulated Bus duct with inner diameter of each conductor 64 mm and diameter of enclosure 500 mm is considered. Three particle of different sizes assumed to be rest at a position. Switching Impulse Voltage of 1050 kV is superimposed on Power frequency voltages of 245 kV, 300 kV ,400 and 450 kV are applied to Three Phase GIS bus The motion of the three particles are simulated for different voltages using MATLAB. Effect of the three particles for Switching Impulse Voltage super imposed on power frequency on particle movement are analyzed and time of collisions of the particle at first time is determined for various voltages. And also the horizontal and vertical distances at which the particles collide are determined for Particles of aluminum of 10 mm in length and 0.1 mm radius, 10 mm length and 0.15 mm radius and 7 mm and 0.15 radii. The results show that the three particle collide at different points depending on the particles position , the velocity and direction of the particle changes after collisions . The max displacement of the particles without collision are compared with the max radial displacements by considering the collisions. The results show that the max displacement of particles is higher as compared with without collisions.
