Abstract

This work is a contribution to the characterization of the electromagnetic properties of high temperature superconductors (HTS) made of Bismuth Strontium Calcium Copper Oxides (BSCCO). The electromagnetic proprieties (critical current density and self-field AC losses) of a tape and a coil are determined experimentally at different frequencies, and compared to analytical models and finite element simulations for a better analysis of the physical phenomena. As shown in this work, the transition from the element to the system is not straightforward, and the characterization of such a material at the system scale is necessary due to their high sensitivity to the magnetic field. Solutions to some measurement problems are also highlighted.
