    Abstract: Short circuit current cause great threat to the safe and stable operation of the power system. Saturated core type Superconducting Fault Current Limiter (SFCL) has a lot of advantages such as small steady impedance, low loss, short recovery time, and good current limiting effect. It is one of the ideal equipment for limiting short circuit current in power system. The working principle of saturated core superconducting fault current limiter is introduced. And its development situation is expounded. Based on these, this paper analyzed the key problems of its application technologies.
