Black-Box Power Transformer Winding Model

2022 7th International Advanced Research Workshop on Transformers (ARWtr), 2022
In the paper high-frequency black-box model of a power transformer winding is presented. The model is based on high-frequency measurements of the winding admittance matrix, using commercial VNA equipment. The winding admittance matrix is measured for every two discs of the winding.

Power Transformer With Superconducting Windings

[1993] Digests of International Magnetics Conference, 1993
A 330-kVA power transformer with superconducting windings is discussed. A niobium-titanium based superconducting wire optimized for AC applications was used in the windings. The transformer worked according to its design at rated power. The total heat input to the liquid helium bath at this power was 9.4 W, of which the AC losses dissipated in the ...
