Abstract
A formulation for the computation of AC losses in technical HTS conductors by using commercial FEM packages developed for two-dimensional computation of electromagnetic problems is presented. The formulation takes into accoun t the real current density-electric field characteristic of a conductor and the spatial dependence of the current density. Having presented the formul ation, example runs comparing transport current loss behaviour between HTS and LTS conductors are given. (C) 1998 Elsevier Science B.V. All rights res erved.
