A superconducting fault current limiter (SFCL) is a device designed to protect power systems from excessive fault currents. Superconductors exhibit a phenomenon known as quenching, in which they transition to a resistive state when the current exceeds a critical threshold, thereby enabling rapid fault current limitation. LS ELECTRIC, in collaboration with KEPCO, developed a 22.9 kV / 2.0 kA resistive superconducting fault current limiter (R-SFCL) and installed it at the Seogochang Substation for commissioning. Before integration into an actual power distribution system, a low-voltage load test was conducted to verify that the temperature of the liquid nitrogen inside the SFCL remained stable under various thermal load conditions. The load current profiles were established on the basis of seasonal and daily electricity consumption patterns in Korea and also included extreme scenarios involving abrupt load increases.
