Partial discharge characterization of cross-linked polyethylene medium voltage power cable termination defects at very low frequency (0.1 Hz) and power frequency test voltages

Most power cable faults begin as defects in the cable accessories: terminations, joints, and junctions. Poor workmanship is a common cause of the accessory faults [1], [2]. A contributing problem is that power cable accessories are sometimes conveniently assembled manually on site by subcontractors rather than by the cable or accessory manufacturers, thereby increasing the risk on compromising quality.
