Abstract

Models are proposed for two major components of the coupling eddy currents, induced inRTD- HTSC power transmission cables by a time varying transverse magnetic field. Weconsider multi-layer, multi-tape cable designs in which the winding directionalternates with each layer. By assuming unsaturated operation in the tapes wecalculate resistive losses for a wide range of possible inter-tape contact resistances.Specific results are given for two hypothetical tape models corresponding tomulti-filamentary OPIT (Oxyde-Powder In Tube) and thin film IBAD (Ion Beam AssistedDeposition) elaboration processes. Conclusions are made on the constraints that theresults may take place on the future designs: particularly, on the decision whether ornot to insulate the winding layers.
