Electric field-space charge profiles obtained using the laser-intensity-modulation-method (LIMM) are presented for XLPE samples extracted from power cable insulation cross-linked using dicumyl peroxide. The samples, 110 /spl mu/m thick with vacuum-evaporated aluminium electrodes, were subjected to d...
