To Study the Breakdown Voltage for Different Electrode Configuration by using 10; 90, SF6-N2 Gas

Gas protected substation have been significant advancement in power transmission and circulation with demonstrated dependability and support free activity. The use of GIS has expanded quickly in the course of recent a very long time for their benefits. Despite its great electrical protection properties. SF6 gas is accepted to be profoundly harmful and destructive compound, when exposed to electrical releases. Additionally SF6 has high affectability to the non – consistency of electric field, which would reduce the great protection properties [1-2]. Because of the different downsides of SF6, there is a compelling impulse worldwide to utilize gas combinations instead of SF6 gas. Breakdown strength of gas combinations has been assessed. The testing high ac voltage is done. The examination rehashed with dielectric covering to the control transmitter. At the point when an adequately high electric field is applied to a gas, torrential slide ionization (TOWNSEND PROCESS) happens which will prompt breakdown. Breakdown Voltage (BDV) of air or gas assumes a significant part in the High Voltage Engineering. BDV of various terminal setups is one of significant investigations for Scientists and Engineers. Covers assume a significant part in the BDV of any High Voltage System. The Gas Insulated System can be mixture of N2- SF6. The blend of the gases is because of the way that SF6 gas alone is viewed as the ozone depleting substance.
