630kVA high temperature superconducting transformer

Cryogenics, 1998
This document describes the 630 KVA HTS transformer project made by ABB jointly with EDF and ASC. The project started April 1994 and its goal was to manufacture a real scale superconducting distribution transformer and to operate it during one year in the grid of Geneva's utility (SIG).

High temperature superconducting transformers [PDF]

, 2005
The paper provides an overview of power applications of High Temperature Superconductivity (HTS) with emphasis on superconducting transformers. Properties of available HTS materials are reviewed and modelling aspects briefly introduced. A conceptual design of a 240MVA HTS grid autotransformer is summarised and principal features discussed.

Superconducting screening for squid flux transformers

Cryogenics, 1977
When a SQUID (Superconducting Quantum Interference Device) is used as a detector of magnetic flux, it is common practice to couple the flux to be measured into it via a flux transformer. As Fig. 1 shows, there is a need for an effective shield around the interconnexions of the two coils of the flux transformer.

Structural Transformation and Superconductivity in A-15 Compounds

Journal of the Physical Society of Japan, 1977
The correlation between superconductivity and structural transformation in the A-15 compounds are examined in a unified way on the basis of the Gor'kov three-dimensional model and the anisotropic pairing interaction. The temperature dependence of the elastic modulus, the strain order parameter and the energy gaps of superconductivity are obtained and ...

Superconductivity and Martensitic Transformations in A-15 Compounds

1977
I would like to discuss the current theories of the martensitic transition in A15 compounds and our understanding of the interplay between the martensitic transition and superconductivity. Labbe and Friedel 1/ proposed that the martensitic transition is driven by an electronic band Jahn-Teller effect.

Feasibility of a power transformer with superconducting windings

Proceedings of the Institution of Electrical Engineers, 1970
Although only 0.2% of the total power of a large generator transformer is accounted for by I2R losses, the capitalised value of this power dissipation is about half the price of an 800 MVA transformer. Superconducting windings with no power losses are therefore a potentially attractive substitute for existing copper windings.
