We have performed an EMTDC simulation for the current limiting effects of a superconducting fault current limiter (SFCL). A three-phase fault in the 154 kV transmission line between the gaepo and Sungnam substations produced a fault current of up to 60kA. The SFCL with 100 Ω impedance after quench limited the current to 17kA within a half cycle. This limited current is well below the upper limit of a circuit breaker, suggesting the impedance of the SFCL in the transmission line is sufficient.
