Abstract

Abstract: Alumina ceramics are widely used as high-voltage insulation material due to its good electric insulation. As we all know that the defects inside the ceramic have great impact on the insulation property of the ceramics, especially the pores. For a better understanding of the effect of the pores, we carried out the fundamental study of how the pores affect the electric field distribution inside alumina ceramics by simulation and theoretical analysis. The results showed that the electric field strength inside the pore is higher than that without any pores inside the ceramic and the increased proportion is almost constant which is not relative to the size and location of the pore.
