Application Feasibility of Permittivity Graded FGM (Functionally Graded Materials) for Gas Insulated Equipment

Abstract

For the size reduction of electric power equipment, the electric field stress around solid insulators is to be carefully designed. This concern will be solved by the application of FGM (Functionally Graded Materials). In this paper, we investigated an application feasibility of FGM from numerical simulation, and the fabrication technique for gas insulated equipment. Finally, we could confirm the significant effect of FGM application for gas insulated equipment. © 2005, The Institute of Electrical Engineers of Japan. All rights reserved.
