On special Backlund autotransformations
Journal of Physics A: Mathematical and General, 1991All Klein-Gordon, omega xy=f ( omega ), and evolution, omega t=f ( omega , omega x,. . ., omega x.7T. .$x), equations admitting autotransformations phi =a( omega ) are found (a( omega ) is such a function of omega and its finite-order derivatives that any solution omega is mapped into a solution phi of the same equation).

Tertiary windings in autotransformers
Electrical Engineering, 1961AUTOTRANSFORMERS in power systems are usually Y-connected and commonly have delta-connected tertiary windings. Is the tertiary winding needed? If needed, what should be its size? These are two questions to consider when applying an autotransformer.

Three-Phase/Six-Phase Conversion Autotransformers
IEEE Power Engineering Review, 2002The first commercial demonstration of six-phase transmission, the Goudey-Oakdale three-phase/six-phase project, used two delta wye-grounded three-phase transformers to realize the required phase/voltage conversion. This paper proposes the usage of autotransformers for phase/voltage conversion for the actual three-phase/six-phase systems to be built in ...

Power autotransformer electromagnetic radiation analysis
IEEE 6th International Symposium on Electromagnetic Compatibility and Electromagnetic Ecology, 2005., 2006This work describes power autotransformer radiation model. Experimental results have been compared with calculation. We suggest a method for diagnosing technical condition of power transformer according to its electromagnetic radiation.

Analysis of Networks with Complex Autotransformers
IEEE Transactions on Power Apparatus and Systems, 1963The open-path-closed-path (mixed junction pair and mesh) relations derived in Part I1 are related by invariant transformations and their inverses to the open-path (junction pair) relations with reference ground and reference different from ground.

40 DEG PHASE-SHIFTING AUTOTRANSFORMER
2005The invention relates to a transformer for converting three-phase power into nine-phase power, in particular for a rectifier. The inventive autotransformer is embodied in the form of a step-up or step-down transformer. For a step-down transformer, three-phase input terminals (E1,E2, E3) are delta-connected to one of main windings, mounted on the ...
