The fault recovery performance of a helium-insulated rigid AC superconducting cable

If a through fault causes overheating of a superconducting cable, the cable cannot be used until the normal operating temperature is re-established. Since this could take more than a day, the cable must be designed so that the largest through fault expected will not overheat the cable system. This paper describes both a theoretical analysis of the behavior of a rigid coaxial ac superconducting cable system during and following a through fault as well as the theoretical and experimental verification of the ability of this design to continue to deliver power following a through fault.
