Abstract

Crosslinked polyethylene (XLPE) cables are widely used for ac transmission. However, for dc transmission, they are still under feasibility study due to severe concern about space charge. In the bulk of XLPE insulated cables, there remain chemicals such as acetophenone and α-methylstyrene. Several kinds of investigations on the effect of acetophenone on the space charge distribution in polyethylene (PE) have been done. In the present paper, the effects of acetophenone, α-methylstyrene, and cumylalcohol on the space charge evolution in PE have been compared by measuring charge distributions and dc conduction currents in soaked PE sheets
