Abstract: Due to rapid growth of population, energy utilization increased which substantial required reliable, economical and flexible technology to meet the demand. The unique properties of Gas insulated systems (GIS) made it an alternative to meet the demand. Power engineers face a lot of challenges during GIS components design. GIS generally fail to operate in case of insulation and spacer failures as it leads to increase of electric field stress at the triple junction. Though utmost care has been taken during the manufacturing process, minute imperfections in the form of voids, delimitations, protrusions, cracks, etc., can occur which leads to the operation failure of GIS. Hence, for high level of dependability, vital importance is to be given to the electric field pattern along the surface periphery of the spacer. In this paper, analysis of electric field for a Polymeric spacer with different Filler concentrations of Nitrates, Carbides and Oxides under the void imperfection is carried. The reduction of Electric Field is carried with the insertion of metal inserts. The results are presented and analysed for different voltages without and with metal inserts.
