Superconductive windings in power transformers

Journal of the Institution of Electrical Engineers, 1963
The superconducting elements exclude all magnetic field from their bulk and restrict conduction within a few hundred angstroms of their surface, but there are alloys in which d.c. superconduction occurs in depth. The paper examines the electromagnetic behaviour of both these forms of superconductor, and includes a description of the loss mechanism in ...

Are transformer stabilizing windings necessary?

Electrical Engineering, 1959
FOR MANY YEARS it has been common practice to include a Δ-connected stabilizing winding in Y-Y-connected transformers and Y-connected autotrans-formers. This applies to 3-phase units of all types of core construction as well as 3-phase banks of single-phase units. The practice has been followed so closely for such a long time that it is generally taken

Graded windings for pulse transformers

Proceedings of the IEE Part C: Monographs, 1962
The paper provides a comparison of conventional with graded windings used in pulse-transformer design. A conventional winding is defined as one in which the interlayer dielectric thickness is constant over the winding length, while the graded winding is defined as one in which the interlayer dielectric thickness varies linearly over the winding length.

Mechanical stresses in transformer windings

Journal of the Institution of Electrical Engineers - Part I: General, 1946
The forces and stresses set up in transformer windings and their clamping structures, as the result of external or internal short-circuits or of switching operations, are considered in detail. Various arrangements of windings and tappings in large power transformers are described.

Frequency Characteristics of Transformer Windings

2013
Transformers are subjected to voltages and currents of various waveforms while in service or during insulation tests. They could be system voltages, ferroresonance, and harmonics at low frequencies, lightning or switching impulses at high frequencies, and corona/partial discharges at ultra-high frequencies (a brief explanation is given at the end of ...
