Determination of Dielectric Losses in a Power Transformer
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 ...

Dielectric constant and losses in a magnetic field in RexMn1-xS solid solutions (Re = Gd, Yb) [PDF]
Polycrystalline samples GdxMn1-xS and YbxMn1-xS with a concentration x = 0.2, near the ions percolation concentration through the face-centered cubic lattice, are studied in order to determine fluctuations in the valence of the ytterbium ion on ...

Dielectric Losses of Doped Colored Crystals
The dielectric losses of KBr single crystals doped with BaBr2 at different concentrations, both uncolored and additively colored, have been measured. A maximum in the dielectric loss versus frequency curve in the additively colored crystal was observed ...

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