The effect of magnetic field on the trajectory traced by a metallic particle in a gas insulated bus duct

A method based on particle motion is proposed in this paper to determine the particle trajectory in GIS or Gas Insulated Bus duct. In order to determine the moment of a particle in GIB, an inner electrode of diameter 55mm and outer enclosure diameter of 152 mm is to be considered. Aluminum, Copper and Silver wires of 0.5mm diameter and 10mm and 7mm lengths are considered to be present on the enclosure surface. The charge acquired by the particle is now under the influence of magnetic field set up by the conductor when electric current is passed through it. The particle that has acquired charge behaves as a moving charge & a moving charge placed in a magnetic field experience a force. The force acquired by the particle is additive as the magnetic force is due to the current flowing in the electrode and the moving charge is due to electrostatic force setup. The motion of the wire particle is to be simulated using the charge acquired by the particles at site, drag coefficient, Reynolds number and coefficient of restitution. The distance traveled by the particle is to be calculated using appropriate equations. The results are also to be presented for other set of parameters.
