Abstract

A superconducting parallel bifilar winding with one strand in each branch was tested and analyzed. When quenched by a fault current, it showed the so-called "fast quench" and the experimental results explained the increase of resistance. Also the experiments confirm that the current redistribution of magnetically coupled strands develops new normal zones after the initial quench, and that the size of normal zones at an early stage increases almost linearly as dI/dt increases. By these results, we could explain the resistance rise of the superconducting parallel bifilar winding when quenched by a current above the critical value.
