However, bow-tie tree caused by the presence of minute moisture and foreign matter in the cross-linked polyethylene, and the occurrence of the vented tree similar to the E-T type cable are concerned in the case where the water barrier measures are not applied to the cable. E-E cables with such water trees can be found by the residual charge method. However, it is impossible to grasp the cable section where the water tree occurs. Since similar events will increase due to aging in the future, research focusing on locating the weak insulation part is useful. In this report, we describe the propagation characteristics of tree charges in cables of E - E type CV cable which 28 years have passed.}, pages = {143--147}, title = {CVT ケーブルの劣化位置標定に関する基礎研究}, volume = {47}, year = {2018}, yomi = {イケダ, ユウスケ and サコダ, タツヤ and サトウ, ヒデアキ and ハルヤマ, ヒロシ and ミヤザキ, カズノリ} }
