Abstract
The interpretation of dielectric losses is crucial for ensuring the reliability, safety, and long-term performance of high-voltage (HV) insulation systems. Electrical insulation used across various sectors − including power grids and transportation electrification − is subjected to HV waveforms that often contain harmonics, arising from widespread power-electronic conversions, non-linear components, and transient phenomena. This paper highlights the contribution of power losses associated with partial discharges (PD). Specifically, it introduces a methodology and measurement approach for quantitatively extracting PD-related power losses induced by HV harmonics and examines the role of the phase angle in either amplifying or attenuating these losses. The investigations were conducted on a polyethylene specimen containing void, representative of typical HV insulation materials, as well as on a segment of deteriorated XLPE power cable. It was observed that the PD inception voltage is influenced by the local slope derivative of the applied waveform modified by the presence of harmonics. Furthermore, the evolution of the ratio between conduction and polarization losses and PD-related losses as a function of voltage was investigated. The presented quantitative analysis confirms the influence of harmonics and phase angle on the dynamics of PD-originated losses in HV insulation systems. The reported methodology has potential both in the design of power equipment and in the diagnostics of HV insulation systems.
