Abstract
Interpretation of dielectric losses is critical for high-voltage insulation reliability and long-term endurance. Electrical insulation in various sectors, such as power grids and transportation electrification, is exposed to high voltages (HVs) containing harmonics due to ubiquitous power electronic-based conversions, nonlinear elements, and transients. This letter highlights the contribution of partial discharge (PD)-related power losses. In particular, it presents a methodology for the quantitative extraction of PD-related power losses caused by HV harmonics, as well as the role of the phase angle in either amplifying or attenuating these components. The investigation is performed on a polyethylene specimen, typical for HV insulation. The results clearly indicate the influence of the harmonic phase angle on the quantitative contribution to PD power losses. The presented methodology can be useful both in the design of HV insulation systems and for diagnostic purposes.
