dc.description.abstractHigh voltage XLPE cable cores have been subjected to wet ageing following the recommendations in CIGRE TB 722. The electrical ageing was performed at 500 Hz and 10 kV/mm. Vented water trees were detected initiating and growing from the semi-conductive screens. The inception sites of the trees were cut by cryo-microtomy and studied using scanning transmission electron microscopy with energy dispersive X-ray spectroscopy (STEM-EDS). Inorganic impurities were detected on both sides of the smooth XLPE-semiconductive screen interface close to the inception site.
