Abstract
The flux-lock type superconducting fault current limiter (SFCL) has the attractive characteristics that can adjust the current limiting level by the turns ratio between two coils. Since the recovery characteristics of a superconducting element m the flux-lock type SFCL were dependent on the turns ratio between two coils, the analysis for the recovery characteristics of this type SFCL together with the current limiting characteristic is necessary to apply it to power system. When the applied voltage and load impedance were same, the recovery time of the superconducting element was 0.32sec in case that the turn's ratio between the primary and secondary windings was 63:21. In the meantime, when the turn's ratio of secondary winding increased to 3 times, the recovery time became longer to 0.58sec.
