Void를 갖는 가교폴리에칠렌의 유전특성과 온도의존성

Temperature Dependency and the Dielectric Characteristics of Crosslinked Polyethylene with Void

This paper was evaluated dielectric characteristics and temperature dependency in the XLPE with and without void. Each dielectric loss was $3.5{\times}10^{-4}$(%) and a little decreased with temperature's increase. Capacitance presented a contant value. According as the study is obtained results, loss in the XLPE increased in proportion to square of applied voltage. As a result of the study, it was knowed that dielectric characteristics had a great deal to do with degradation in the high voltage dielectric materials.
