Abstract :
The temperature dependence of space charge distribution in XLPE cable has been investigated using the pulsed electro-acoustic (PEA) method. Heterocharges were observed near both the electrodes when DC voltages of 30 and 40 kV were applied. Once formed, the heterocharges remain for a long time. However, they disappear with increasing temperature up to 80 C. With heat treatment up to 80 C, a large amount of the space charge seems to be removed from the XLPE cable
