Prediction of Critical Currents in Superconducting Windings Using Wire Data and Field Modeling

This paper reports on the integration of publicly available HTS conductor electromagnetic performance data into a magnetic Finite Element model for determining critical current distribution along section in spatially fluctuating field. The simulation results from this are shown to be close agreement experimentally obtained results. Typically monitoring quench is done by measuring volt-drop protected and when reaches predetermined level. work shows that under varying field conditions, small areas voltage monitored could have already surpassed level hence stand high probability being site quench. Under these it proposed use maximum electric developed as criterion current. points need developing detection technique can applied much smaller sections conductor, particularly geometries expected experience largest variations such rotating machine.
