Summary

The authors have developed a niobium-tin 400-kilovoltampere class alternating-current coil composed of a six-stranded cable with a stainless steel center strand. The major component of alternating-current loss was the coupling loss. The temperature margin was as high as 4.19 K at the cable just before quenching. The reduced critical current due to the temperature rise was found to be consistent with the quench current. The niobium-tin coil was proven to have a temperature margin large enough to be robust against power system failures.
