Abstract

We have performed an EMTDC simulation for the current limiting effects of a superconducting fault current limiter (SFCL) for the 154 kV transmission line between the Gaepo and Sungnam substations. The fault current increased up to 39 kA during an artificial ground fault. The SFCL with 100 ${\Omega}$ impedance after quench limited the current to 15 kA within a half cycle. This limited current is well below the upper limit of a circuit breaker, suggesting that the impedance of the SFCL in the transmission line is sufficient.
