Determination of Dielectric Losses in a Power Transformer

open access: yesEnergies, 2022
The article presents a method of determining dielectric losses that occur in insulating materials in a power transformer. These losses depend mainly on the electric field stress, pulsation, dielectric loss coefficient, and electrical permittivity of ...

Effective parameters of dielectric absorption of polymeric insulation with semiconductor coatings of power high voltage cables

open access: yesElectrical engineering & Electromechanics, 2022
Introduction. The presence of semiconductor shields leads to additional dielectric losses compared to polymer insulation without shields. Losses in cables in the presence of semiconductor coatings depend on the dielectric permittivity and resistivity of ...

Unique-Solution Single-Sample Complex Dielectric Characterization Through Linear Phase Approximation

open access: yesIEEE Open Journal of Antennas and Propagation, 2022
This paper presents a transmission-only (TO) approach that solves the long-standing problem of transmission phase ambiguity. The approach considers a linear frequency-dependent phase approximation to derive the phase mode value analytically and uniquely ...

Dielectric Loss of Boron-Based Dielectrics on Niobium Resonators [PDF]

open access: yesJournal of Low Temperature Physics, 2019
Advanced solid-state quantum bits (qubits) are likely to require a variety of dielectrics for wiring crossovers, substrates, and Josephson junctions. Microwave superconducting resonators are an excellent tool for measuring the internal dielectric loss of materials. We report the dielectric loss of boron-based dielectric films using a microwave coplanar
