For the size reduction and the enhancing reliability of electric power equipment, the electric field stress around solid insulators should be considered enough. For the relaxation of the field stress, the application of FGM (Functionally Graded Materials) with spatial distribution of dielectric permittivity (¿-FGM) can be an effective solution. In this paper, we investigated the applicability of ¿-FGM for reducing the electric field stress on the electrode surface with contact to the solid… CONTINUE READING
