Abstract
The power cable is one of the most important transmission equipment. The long cable common use the cross-bonded grounding method to reduce the loss of shielding layer and decrease the voltage rise at the end of cable. Therefore, it is difficult to diagnosis the PD detection result of cross-bonded cable in field because the PD signals will be influenced by both the environment electromagnet interference and the interference among different phases. The broad band sensor is used to detect the PD of cross-bonded cable in field in this paper. The waveform of the PD pulse, PRPD, and 3PARD diagrams are analyzed to diagnose the results. The results have shown that the broadband sensor can anti the environment electromagnet interference because it can obtain more information of PD signal. The 3PARD diagrams can division the interference among different phases.
