Internal Structure and Electrical Behaviour of Water Trees in Polyethylene

풀리에틸렌 내에서의 워터트리의 구조와 전기적 특성

It is shown that water tree grown using the water needle method in polyethylen do not behave as conductor but as dielectrics. It is decuded that water trees are not non-interconnected cavities. This result is confirmed by gas flow measurements through freeze-fractured water trees.
