Full text: PDF


As the damage of XLPE power cable insulation is usually caused by water tree deterioration, it is very important to make on-line diagnosis on it. Bases on the theoretic analysis of AC superposition method, this paper analyzes the detecting principle of 101Hz signal and presents the design of this diagnostic method system.
