The effect of voltage reversal and elevated temperature on space charge behaviour in XLPE cable
The effect of voltage reversal and elevated temperature on space charge behaviour in XLPE cable
Space charge accumulation in XLPE power cable insulation under dc electric stress and polarity reversal was experimentally studied. It has been found that once space charge appears in the insulation of high voltage dc (HVDC) cable, polarity reversal becomes a crucial operation to cable insulation. The space charge accumulated prior to polarity reversal is fairly stable and can lead to a severe distortion of electric stress through cable insulation immediately after the reversal. To mimic loaded dc cables in service, space charge distribution in a cable with a temperature gradient was also reported.

Abstract
Space charge accumulation in XLPE power cable insulation under dc electric stress and polarity reversal was experimentally studied. It has been found that once space charge appears in the insulation of high voltage dc (HVDC) cable, polarity reversal becomes a crucial operation to cable insulation. The space charge accumulated prior to polarity reversal is fairly stable and can lead to a severe distortion of electric stress through cable insulation immediately after the reversal. To mimic loaded dc cables in service, space charge distribution in a cable with a temperature gradient was also reported.
