The partial discharge characteristics of four defects in heat-shrinkable cable accessories, which were termination without stress tube, incorrect use of insulation tape as semi-conductive adhesive tape in the middle joint, void and metal particles on the surface of XLPE insulation, were studied by AC volt-age method and damped oscillating wave voltage method. The partial discharge inception voltage and pat-terns under damped oscillating wave voltage and AC voltage were compared. The results show that the two methods are consistent in the study of partial discharge characteristics, and there are obvious differ-ences in the partial discharge statistical characteristics of various defects.
