Abstract:
1. A superconducting fault current limiter (SCFCL) system comprising: a first SCFCL; a second SCFCL; and a controller configured to control at least one switch to couple the first SCFCL to a power line between an AC source and a load, and to electrically isolate the second SCFCL from the power line during a first operating mode when the first SCFCL is in service and the second SCFCL serves as a spare, wherein the controller is further configured to control the at least one switch to couple the second SCFCL to the power line between the AC source and the load, and to electrically isolate the first SCFCL from the power line during a second operating mode when the second is SCFCL is promoted into service and the first SCFCL is demoted from service.
