  • Superconducting fault current limiter for suppressing bus voltage drop in electric power system
    Patent number: 8810978
    Abstract: Disclosed herein is a Superconducting Fault Current Limiter (SFCL) for suppressing a bus voltage drop in an electric power system. A primary winding, a secondary winding, and a tertiary winding are wound around an identical iron core, and a superconductor is connected to any one of the primary winding and the secondary winding. A first switch is connected to any one of the primary winding and the secondary winding and is configured to be opened so as to separate a faulty section when a fault current is generated and to be shorted when the fault current is eliminated. A second switch is connected in series to the tertiary winding and is configured to be shorted so as to stably supply power when the fault current is generated and to be opened when the fault current is eliminated.
