“…Lee et al [9] carried out a series of experiments to determine the resultant partial discharge behavior of defects inside cable insulation at a termination. Other researchers [10][11] have introduced AC voltage and investigated the resultant PD pattern in different kinds of cable termination defects. However, there is little research investigating the behavior of cable insulation with defects when exposed to a DC voltage combined with an AC harmonic voltage.…”

One of the challenges on the increasing reliance on isolated renewable generation sources is the transmission of power from these sources to centers of power demand. One possible approach is the use of high voltage direct current (HVDC) transmission. The power electronic converters are key components in HVDC transmission system. The converters produce the intended DC voltage for transmission but there may also be AC harmonics superimposed. The superimposed harmonics on the HVDC may have synergistic effects and may lead to further degradation in the cable insulation. Previous research has shown that partial discharge was the main cause of degradation in polymeric insulation under AC stress. However, few publications have demonstrated the effect of combined stress on cable insulation degradation. Additionally, the most popular cable insulation material, cross-linked polyethylene (XLPE), cannot be recycled. Alternative materials which can be recycled have been proposed and one such solution could be thermoplastic materials. In this study, HDPE was investigated as a reference material for thermoplastics and their potential use as insulation in HVDC cables. In this paper the effect of frequency on HDPE degradation under superimposed stresses was studied using the following approaches; equivalent phase resolved partial discharge (PRPD) plots, fourier transform infrared spectroscopy -attenuated total reflection (FTIR-ATR) and dielectric spectroscopy (DS) measurements were carried out. The results show that during aging and with a frequency increase, the voltage of PD events increased which in turn created more polar molecule groups on the surface. The amount of polar molecule groups was found to affect ε' and tanδ, with both increasing when more polar molecules were created. The results show that applying a higher AC frequency enhances polymer degradation.

“…Many studies have reported that corona discharges are indirectly generated from the cable or its termination but may originate from the switchgear and cable/terminal hardware connection [9]. Many researchers [20], [22]- [24] used a needle or electrode as a sharp point in their experiments to analyse the characteristics of corona discharges in XLPE cables. The shape of the electrodes under HV stress enormously influences the corona discharge characteristics at low inception voltage.…”

Partial discharge (PD) signal classification analysis on cross-linked polyethylene (XLPE) cables is complex, requiring a comprehensive understanding of the characteristics of PD patterns. In the realm of high-voltage electrical insulation, PD pattern characteristics, such as PD charge and inception voltage, are essential as assessment criteria in diagnostics systems using PD classifiers. This paper provides a review of various PD patterns and classifiers used by previous researchers, specifically for XLPE cables. In addition, the differences of the research on various sensor development based on PD detection in the past 27 years are also discussed. The repeatability, recognition accuracy, recognition speed, and effect of feature sizes on each PD classification method are reviewed and explained. The review indicates that the pattern recognition for PD signal using artificial neural network (ANN) exhibits better performance in terms of accuracy and repeatability than the other methods, and the reduction of feature size does not affect the accuracy of ANN.INDEX TERMS Partial discharge (PD), cross-linked polyethylene (XLPE) cable, solid insulator, pattern recognition, feature extraction, artificial neural network (ANN)

The authors have been developing a new measurement method for measuring partial discharge (PD) in a long‐distance cable line using a capacitive coupling method. This method proposes that a PD signal can be detected by a newly proposed capacitive coupling electrode between the shielding layer and an additional aluminum foil. In this article, first, the theoretical background of the proposed method was described including the generation, propagation, and detection of the PD signal. Second, the proposed method was applied to observe PD activity in an RG58A/U communication cable and a numerical simulation was also performed in the same manner as the measurement system. It was confirmed that the PD signal was successfully detected. Third, the feasibility of the proposed method for applying in a full‐size 6.6 kV XLPE, (Hitachi Cable Ltd., Hitachi Magnet Wire Corp., Tokyo, Japan) cable line was investigated. It was revealed that the proposed method can be applied for a full‐size cable. Finally, an attempt was made to understand the effect of the coupling capacitor on the detection intensity. Also, the detection limit of the proposed method based on the noise level was analyzed. It was revealed that the detection sensitivity was finally determined as 400 pC, which was the detection limit. © 2019 Institute of Electrical Engineers of Japan.
