Partial Discharge Characteristics of Epoxy Composite due to Internal Void

Epoxy 복합체의 내부 보이드에 따른 부분방전특성

Stability of inside power equipments are required for electron equipment in order to operate those safely. Also, the power circuits for these have been developing, but research of dielectric strength of power supply is insufficient. In this paper, for test insulation condition variation by void it is tested insulation characteristics variation, using $\phi-q-n$ distribution variation in partial discharge test.
