Space charge measurement in XLPE cable with temperature gradient through the insulation
Space charge accumulation in XLPE power cable insulation under dc electric stress at room temperature and gradient temperature across the insulation was experimentally studied. It has been found that space charge is of a constant accumulation rate at room temperature and quite stable as soon as it is generated. In contrast, elevated temperature has not only reduced the charge density but also accelerated space charge accumulation and decay speed.
