In this paper was proposed a flux offset-type fault current limiter as means of reducing faultcurrents. To secure the operation reliability of a flux offset-type fault current limiter, constructed asimulation system to analyze its operation characteristics by generating a double line-to-line fault. According to the test results, the system performed stably without any impedance. However, when anaccident occurred, the flux-offset of magnetic was not occurred. Because of this, any impedance occurredat circuit. It was confirmed that the impedance was low and fast to limit the fault current. At this time,the fault current limited rate was about 95%.
