      abstract = {A superconducting shielded core reactor (SSCR) operates as  a passive device for limiting excessive AC current in a  circuit operating at a high power level under a fault  condition such as shorting. The SSCR includes a  ferromagnetic core which may be either closed or open (with  an air gap) and extends into and through a superconducting  tube or superconducting rings arranged in a stacked array.  First and second series connected copper coils each  disposed about a portion of the iron core are connected to  the circuit to be protected and are respectively wound  inside and outside of the superconducting tube or rings. A  large impedance is inserted into the circuit by the core  when the shielding capability of the superconducting  arrangement is exceeded by the applied magnetic field  generated by the two coils under a fault condition to limit  the AC current in the circuit. The proposed SSCR also  affords reduced AC loss compared to conventional SSCRs  under continuous normal operation.},
