This paper reports that the authors have developed and tested a 6.6 kV/1.5 kA-class fault current limiter wound with a 42-strand AC superconducting wire having ultra-fine MbTi filaments in a high resistivity matrix. In experiments, voltages up to 7.2 kV were applied to the limiter with phase angles of 0, 45, and 90 degrees. The limiter was able to limit the fault current to 1.8 kA successfully from the 55 kA short-circuit current that would flow in a circuit without limiter.
