Abstract:
A current limiter system includes a superconducting fault current limiter (SCFCL) operative to conduct load current during a normal operation state in which the SCFCL is in a superconducting state. The current limiter system also includes a shunt reactor connected in an electrically parallel fashion to the SCFCL and configured to conduct less current than the SCFL in the normal operation state, and a protection switch connected in electrical series with the SCFCL and shunt reactor and configured to disconnect the SCFCL for a predetermined time from a load current path during a fault condition after fault current exceeds a threshold current value.
