Eddy current losses in laminated transformer cores

3D Africon Conference. Africon '92 Proceedings (Cat. No.92CH3215), 2003
A finite element method, based on the variational principle, for two-dimensional field configurations is used to evaluate eddy current losses in a sheet of a laminated transformer core assumed to be a linear homogeneous conducting medium. Boundary conditions are imposed in an integral form combined with Neumann conditions.

Eddy-current losses in reactor flux shields

Proceedings of the Institution of Electrical Engineers, 1970
The magnetic-field distribution is analysed for the case of an aluminium plate excited by a circular current loop, and an expression for the eddy-current loss in the plate is deduced. This analysis is tested by comparison with measurements on a model which closely resembles the theoretical geometry, and the results are shown to be in close agreement. A

Eddy-current losses in solid and laminated iron

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1959
In this paper formulas are developed, on the basis of simple physical conceptions, for the calculation of eddy currents in solid and laminated iron, which, as the experiments presented show, enable the losses caused by eddy currents to be predicted with surprising accuracy. A simple formula for the calculation of the power factor (pf) that the magnetic

Computing Eddy Current Losses in Reactor Coils

1988
Reactor coils are electrical components which serve (among others) the following purposes: to limit the current under system fault conditions, to distribute the load to parallel circuits, to reduce the starting current that occurs when elec- trical machines are switched on, to limit short-circuit currents in rectifier equipments.
