“…Compared to AC, the major issue for PD measurements under DC is the absence of phase information. If there is ripple in the applied DC voltage, it can be utilized to help PD analysis as a phase reference, similarly to AC [120]. For DC without noticeable ripple, one can observe only a series of impulses.…”

Partial discharge (PD) detection and analysis plays a crucial role for acceptance testing and condition monitoring of power cables. Various aspects are related to PD in power cables from theory to practice. This paper first summarizes the PD mechanism and models used for PD analysis in power cables. Afterwards, PD detection is addressed in the aspects of off-line test, on-line test, and sensors. PD analysis is discussed in detail. Specifically, related quantities and algorithms for PD analysis are outlined. PD characteristics with affecting factors, e.g., dielectric type, load, and applied voltage are discussed. Experience on PD development trend with measurements in field is analyzed. Based on the comprehensive review, challenges of PD detection and analysis along a power cable are proposed.

“…These ripples are periodic and thus helps to overcome the shortcoming of using PRPD analysis for DC voltage stress. Dezenzo et al [5,22] have carried out PRPD analysis of positive and negative ripple on needle plane configuration and reported that at high voltage, discharge magnitude follows inverse of the voltage curve due to the presence of dominant space charge.

The different phase resolved partial discharge patterns, which can be recognized when a positive dc voltage containing a ripple due to a half-wave rectification is used are presented in this paper. Results are given from corona onset to the appearance of breakdown streamers. The outcomes are five different patterns, which represent the four stages of positive corona and their transition zones. Three of them are clearly identifiable with respect to patterns from other discharge sources that have already been reported for dc voltages containing a ripple. For an assessment of pattern formation discharge pulses as recorded at the test object are presented. Finally, the appearance of patterns is explained with support of the measured discharge pulses and the underlying physical processes.
