Inductive Fault Current Limiters: Kinetics of Quenching and Recovery

We report experimental results from a shielded inductive type superconducting fault current limiter (SFCL) demonstrator incorporating YBCO coated conductor together with results from an analytic study of a large 13 MVA SFCL. Important parameters such as the superconductor temperature rise, re-coolin...

Beschreibung
Zusammenfassung:	We report experimental results from a shielded inductive type superconducting fault current limiter (SFCL) demonstrator incorporating YBCO coated conductor together with results from an analytic study of a large 13 MVA SFCL. Important parameters such as the superconductor temperature rise, re-cooling time and voltage characteristics following a short-circuit quench are discussed. These results are compared with the measured and predictive performance of a resistive type SFCL incorporating a similar volume of YBCO CC and providing the same level of current limiting.
