Investigating charge trapping properties of combinations of XLPE and semiconductive materials in plaques and cable models

摘要

The results of space charge observations performed on test objects having the purpose to investigate polymeric insulation/semiconductor interfaces under DC electrical field are presented in this paper. Combinations of different crosslinked semiconductor and polyethylene insulating materials, are considered. The test objects consist of plaques with extruded semiconductor and cable models, having inner and outer semiconductor.
