要約(英語): The consideration of space charge accumulation characteristics in DC cable systems are important. However, there have not been many reports on the space charge accumulation characteristics at the joints, although there have been many reports at the cables itself. Therefore, space charge accumulation characteristics at the joints must be put into account, since interface charge accumulation caused by the difference in permittivity, conductivity, etc. is likely to occur, since two different types of insulating materials are being used. It is also likely that a polarity reversal of the applied voltage to the insulating material causes an unexpected accident at the joints in the cable system, while in some power transmission systems, the polarity reversal is an inevitable procedure. Therefore, in this paper, we investigated the influence of polarity reversal upon space charge distribution and electric field distribution in two-layered samples composed of different materials, to identify issues in cable joints under DC voltage.
