This paper briefly recalls the scientific origin and R&D history of superconducting fault current limiters. The working princi-ple, generic structure, and equivalent circuitry of resistive type, saturated iron-core type, magnetic shield type, and bridge type super-conducting fault current limiters are introduced. The functional characteristics, technical advantages and disadvantages of resistive type and saturated iron-core type superconducting fault current limiters are analyzed and compared in detail. Real grid application examples of these two types of devices are presented. Discussing the application scope and prospect of superconducting fault current limiters, the paper points out that besides conventional fault current limiting functions, superconducting fault current limiters may become an indis-pensable device in grid integration of distributed renewable generations, and they will play an important role in upgrading power grids by reducing transmission loss and enhancing efficiency in the future.
