Performance Evaluation for Lab-Scale Inductive Fault Current Limiter with Different Iron Core Structures

Inductive superconducting fault current limiter (ISFCL) has shown great potential in limiting large short-circuit current. This paper focuses on the effect of iron core structures of ISFCL. Lab-scaled ISFCLs with different iron core structures are designed and fabricated. Short-circuit properties especially impedance properties are investigated by traditional short-circuit tests. The performance of current limiters with different iron core structures are analyzed and compared.
