Popis:	For power applications of HTS it is crucial to predict their AC losses in the typical operating conditions. We report measurements of energy losses in Bi-2223 multifilamentary tapes carrying AC currents and exposed to AC magnetic fields oriented perpendicular or parallel to their wide surface. Losses have been evaluated at liquid nitrogen temperature by transport and magnetisation measurements. The results have been compared to the experimental values obtained by calorimetric method the values estimated by a numerical model specifically developed of evaluation of AC losses in HTS tapes.
