This paper deals with the operational characteristics of a three-phase DC reactor type fault current limiter (FCL) at a short-circuit test. This type FCL consists of transformers, diodes, and a superconducting coil. In this paper, a superconducting coil, low-Tc SMES magnet, is made of Nb-Ti and the power system of the experimental circuit is 400 V/7 A class. This is a preliminary step to develop its faculties for applications to high voltage transmission line. As the results of the experiment, the values are referred to the limitation rate about 77% and 90% when the turns ratio of transformer was 1 and 2, respectively.
