Abstract :
Based on the laboratory test carried out on 351m 10kV XLPE power cable in which there are some typical PD defects, the method of OWTS for detecting PD in XLPE cable and its accessories was introduced. The time domain characters of the OWTS signal is researched in order to distinguish the PD signal from the disturbance. The PD spectrum of q-m was analyzed. The way to locate the PD point was also introduced. The results of the research had proved that the reliability of the PD detection is improved using the method of OWTS.
