Effect of the Resistance of Two Different Coated Conductor on the Current-Limiting Performance of Flux-Lock Type Superconducting Fault Current Limiters

Current limiting impedance comparison between different designs of iron cores of the flux‐lock‐type superconducting fault current limiter

“…Thus from (6), the nominal impedance of SFCL can be expressed as (19). In this case study, the nominal impedance magnitude could be required as no larger than 0.01 Ω Z SFCL nom = j * 25000p/< (19) Meanwhile, based on the results, the constants in (17) could be approximately obtained as (20) for this case study < E = 0.26 × 10 7 + 0.20 × 10 5 + 0.22 × 10 8 l ag w ag (20)…”

“…Different shapes of iron core are proposed in [19], aiming at improving the SFCL performance. In terms of HTS element, the quench and recovery characteristics of the superconducting material are the most significant features [20]. Meanwhile, the impacts of coil features are currently also being investigated [21,22], with respect to their winding direction, turn ratio and coupling coefficient.…”
