Summary

In the actual lead system where the lead had a temperature distribution from 77 to 4.2 K, the alternative current loss was less than 0.1 watt per pair of leads. The lead successfully transported 1 kiloampere root mean square for more than 2 hours without any thermal runaway or instability. The total 4.2 K heat load of the pair of leads, 1.8 watt, also satisfied the refrigeration restriction for the fault current limiter.
