In the active short-circuit current control measures, superconducting fault current limiter due to its special physical characteristics, has considerable potential for development. The comparison between the superconducting core current superconducting current limiter and other superconducting current limiting devices is conducted. The research and application progress of these current limiters and their superconducting materials at home and abroad are investigated. The topological structure and working principle of the saturated core-type current limiter which is being tried out in China are mainly described. The technical problems such as the core structure, DC winding over-voltage and DC excitation system are also discussed. From the fault identification, superconducting materials, core structure and other aspects of the saturated core superconducting flow restrictor in the future development of key technical issues for the type of equipment in-depth research and development and application of reference.
