도전체와 절연체 계면에서의 전기트링 현상
Electrical Treeing Phenomena at the Interface of Conductor and Insulator
초록
This paper describes a study of electrical tree growth in DGEBA/MDA/SN system subjected to ac high electric field. The dielectric breakdown process, which consists of tree initiation, tree propagation and the complete puncture of the system was investigated. Dielectric breakdown always initiated from the needle tip where the electric field reinforcement is the highest. Higher temperature and voltage accelerated the tree growth and reduced the time to breakdown.
