Topic : Effect of Particle Length and Radius on Movement of Metallic Particle in Single Phase Gas Insulated Bus duct

Authors:A. Giriprasad || M.Surya Kalavathi , PoonamUpadhyay , N.Rama Rao

Abstract:The invention of SF6 insulation gas has revolutionized not only the technology of circuit breakers but also the organization of electrical power transmission lines and substations. Gas Insulated Substations have found a broad range of applications in power systems for more than thirty years because of their high reliability, easy maintenance and small ground space requirement. Metallic contaminants are inexorable in GIS systems and most common causes are mechanical vibrations during shipment and service, thermal expansion/contraction at expansion joints. Free metallic particle contaminants in Gas Insulated Bus duct adversely affect the insulation performance because they can cause serious deterioration of the dielectric strength and thereby the breakdown voltage of the GIS system is reduced. Research studies reveal that free metallic particles seriously decreases breakdown voltage of Gas Insulated Systems. This paper deals with the effect of particle length on the moment of metallic particle in single phase gas insulated bus duct. The simulation of movement of aluminum and copper wire like particles are carried out for various bus voltages 75kV, 100kV, 145KV. The results of the simulation have been presented and analyzed..

Keywords: Charge simulation method, Analytical Method, Gas Insulated Bus duct, metallic particle and Maximum radial movement.
