| Abstract: | The polarity identify technique of three pulse signals for partial discharge detection in joint and lnain insu- lation of 110kV XLPE eable is proposed and researehed. The polarity prineiple of the PD pulse signal spread in different directions of the eable was diseussed. The direction of the PD souree ean be determined by the polarity differenees of the three signals that were pike up by sensors. Finally, the researeh result being confirmed by experilnent in laboratory and by actual measurelnent in a real cable, it is proved that this technical can meet the delnand of on-site detecting PD signal occurred in XLPE cable. |
