    摘要： A superconducting short circuit current limiter (40a) for an alternating current system includes AC reactors having superconducting direct current bias windings (4a, 4b) that at normal conditions maintain the reactor's cores in saturated state. There are at least two AC coils (3a, 3b) for each phase operating at opposite half periods or at both half periods. The reactor may also have an additional feedback coil (42a, 42b) that at least partly compensates for the bias field of the superconducting coil at fault conditions enhancing a limiting capacity of the reactor. The reactor's core can be configured for decreasing its dimensions and mass as compared with known devices and for decreasing core losses. High voltage/high current devices include several standard modules connected in series or/and in parallel. A positional relationship of the modules is defined for decreasing necessary numbers of Amp?re-turns of superconducting and non-superconducting coils.
