Alternating current loss reduction for rectangular busbars by covering their edges with low permeable magnetic caps
Abstract
A method to reduce ac conductive losses in a thin rectangular busbar made of copper is presented. The method is based on a technique, which makes the distribution of the ac current in the cross section of a busbar flatter. Edges of a thin busbar are covered with low permeability magnetic thin layers as caps. The magnetic cap makes the impedance experienced by the current flowing near the edge comparatively larger so that currents cannot get crowded near the edges of a busbar. This method is numerically verified.

Electromagnetic forces in threephase rigid busbars with rectangular crosssections
A threephase busbar arrangement with straight rigid conductors carrying shortcircuit currents is investigated. Calculations are made assuming steadystate ac current with a peak value equal to the peak value of the shortcircuit current. This assumption is used in the related IEC Standards 865/92. In this paper, the electromagnetic forces and current densities are calculated by solving the electromagnetic field diffusion equation numerically, using finite elements. The results are compared with results calculated according to the IEC Standards 865/86, as well as with the corresponding technical revision IEC 865/92. The comparison involves arrangements with rectangular crosssections, as used in ac indoormore » 
Fieldangle dependence of alternating current loss in multifilamentary highT{sub c} superconducting tapes
The energy loss in multifilamentary superconducting tapes has been measured for various orientations of the external ac magnetic field. When the ac loss in parallel and perpendicular fields is known, the loss at intermediate field angles can be predicted over a wide range of field amplitudes. The prediction is based upon the following assumptions: For lowfield amplitudes, the current patterns that would be induced in the tape by the parallel and perpendicular field components can be summed. For highfield amplitudes, the tape only carries the current pattern induced by the perpendicular field component. These assumptions are supported by theory. {copyright}more »
