Eddy current losses due to alternating current strips

IEEE Transactions on Power Apparatus and Systems, 1975
A two dimensional solution for the vector potential and eddy current loss in a plurality of conducting regions due to a plurality of current sources is presented. The solution is applicable to those problems with boundaries which may be aligned with the coordinate surfaces of an orthogonal system of separable coordinates.

Eddy current loss calculation in multiconductor systems

IEEE Transactions on Magnetics, 1983
This paper presents the application of the finite element technique for calculating eddy current losses in multiconductor systems used in power transmission. This paper is a contribution to skin effect analysis in conductors and enclosures of arbitrary shapes.

Analytical solutions to eddy current and excess losses

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2005
Summary: This paper sets out to develop analytical solution to the hysteresis, eddy current and excess losses using the \(T(x)\) model. Based on Steinmetz' postulation, the losses, represented by the area enclosed by the hysteresis loop, are individually formulated in analytical form.

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.
