Acoustic analysis is a substantial method for identification of the defects in high tension
cables. High tension underground cable defects are worth detection using acoustic sensors …

Acoustic detection has features of non-contact monitoring, no influence on the operation of
tested equipment, and little interference by electromagnetic noise. In this paper, the acoustic …

Acoustic Emission (AE) and Electrical Emission (EE) partial discharge (PD) monitoring are
effective methods in detection of the insulation failure in power cables. However, the …

In recent years, power cables have been used in large quantities in urban transmission and
distribution networks, however, cable accessory faults show an increasing trend year by …

This paper presents the comparison of partial discharge (PD) interpretation on three different
standard test objects and defected power cable terminations among an PD acoustic sensor …

Cables will inevitably deteriorate during long-term operation, resulting in a reduction in
electrical insulation strength or even failure. Sonic detection is easy to operate and the …

High voltage cables are widely used and directly associated with the reliability and safety of
urban power transmission. However, nowadays, the ablation defect in high voltage cable …

High voltage cables are of great importance to ensure urban power transmission. Therefore,
this paper focuses on a tough defect, ablation in water-blocking tape of HV cable, and …

Dielectric loss is one of the important indicators to evaluate the insulation status of power
cables. Oscillating wave voltage, as a new emerging detection voltage, has a wide range of …

Power system faults are disruptive and may lead to long power outages. One cause is the
phenomenon of partial discharge (PD). PD events may result in damage to the insulation …
