Current Limitation and Recovery Function for Superconducting Fault Current Limiting Transformer (SFCLT).

Abstract: Superconducting Fault Current Limiting Transformer (SFCLT) is expected to have both superconducting transformer function and superconducting fault current limiter function. We have so far developed the 2 MVA-class SFCLT based on YBCO coated conductors, and experimentally evaluated its current limitation and recovery characteristics. In this paper, we constructed a simulation model for current limitation and recovery characteristics of SFCLT for different HTS coil characteristics and design, and derived the optimized design for the effective current limitation and extended recovery criteria under the rated voltage of the 2 MVA-class SFCLT.
