| Abstract—Recently developed 2G superconducting tapes withhigh resistivity in the normal state at a temperature of 77 K allowus to build transformers with high short-circuit strength. High resistance of the HTS windings in the normal state causes the limitationof short-circuit current to the level depend on the value ofthat resistance. Rapid limitation of the short-circuit current can beachieved and the steady-state fault current can be limited to a valueresulting mainly from the parameters of HTS tapes used. The requiredreduction of prospective fault current in a power grid canbe achieved by installing in it a superconducting transformer witha winding made of 2G HTS tape only if the tape provides proper resistance-per-length in normal state at a temperature of 77 K. Thisarticle presents the results of an experimental investigation of a1-phase model of a superconducting transformer, with special regardto the possibility of limiting the short-circuit current by thesuperconducting winding, according to the parameters of the HTStapes used, in parti |
