Characterization of Defects Inside the Cable Dielectric With Partial Discharge Modeling
The continuous monitoring of power system devices is an important step toward keeping such capital assets safe. Partial discharge (PD)-based measurement tools provide a reliable and accurate condition assessment of power system insulations. It is very common that voids or cavities exist in every solid dielectric insulation medium. In this article, different voids are modeled and analyzed using an advanced finite element (FE)-based...

Inception and Propagation of Electrical Trees in the Presence of Space Charge in HVAC Extruded Cables
This paper presents the space charge impact on the inception and propagation of electrical trees in cross-linked polyethylene (XLPE) insulation via simulations and experimentation. A 3D finite element analysis (FEA)-based modeling is proposed to simulate electrical trees via a needle embedded on the XLPE insulation. The proposed FEA model demonstrates the influence of the space charge magnitude and polarity on the initiation of...

Acoustic emission for detecting deterioration of capacitors under aging
W pracy przedstawiono wyniki pomiarów kondensatorów foliowych poddanych przyśpieszonemu procesowi starzenia na ramie trwałości. Stwierdzono, że w niektórych typach kondensatorów foliowych istnieje związek między intensywnością sygnału emisji akustycznej mierzonego w kondensatorach po ich wytworzeniu oraz rezystancji izolacji mierzonej po procesie ich starzenia.
