Abstract:
1. A cryogenically-cooled HTS cable configured to be included within a utility power grid having a maximum fault current that would occur in the absence of the cryogenically-cooled HTS cable, the cryogenically-cooled HTS cable comprising: a continuous liquid cryogen coolant path for circulating a liquid cryogen; and a continuously flexible arrangement of HTS wires having an impedance characteristic that attenuates the maximum fault current by at least 10%, the continuously flexible arrangement of HTS wires being configured to allow the cryogenically-cooled HTS cable to operate, during the occurrence of a maximum fault condition, with a maximum temperature rise within the HTS wires that is low enough to prevent the formation of gas bubbles within the liquid cryogen.
