For the size reduction of electric power equipment, electric field stress around solid insulators is to be increasing, therefore carefully be considered. The application of FGM (Functionally Graded Materials) will be effective solution for this concern. In this paper, we investigated an application feasibility of FGM, from both an experimental approach and numerical simulation. Finally, we could confirm the significant effect of FGM application for gas/solid composite insulation system. The estimation method developed in this paper is also effectively applied to the insulation performance around triple junctions in SF6 gas.
