Abstract :
The proposed DC S/N transition type superconducting fault current limiting interrupter (SCFCLI) uses a high temperature superconducting (HTS) element made of Bi-2223 bulk material. This SCFCLI comprises a device that can not only limit fault current but also interrupt it in a three-phase power system. The current limitation and interruption characteristics of this SCFCLI were numerically analyzed. The confirmation tests were made by a small-scale model in the case of a fault of lines to ground, and test results agreed relatively well with analyses. An SCFCLI for a 6.6 kV-1000 A power system was analyzed based on these achievements.
