Abstract

The short circuit analysis of the integrated three phase flux-lock type superconducting fault current limiter (SFCL), which consisted of three-phase flux-lock reactor wound on an iron core with the same turn´s ratio between coil 1 and coil 2 for each single phase, was performed. In a normal time, the flux generated in the iron core is zero because the flux generated between two coils of each single-phase is canceled out. In a fault time, the integrated three-phase flux-lock type SFCL showed the different fault current limiting characteristics from other three-phase SFCLs with the separated three iron cores. Through the computer simulation for the three-phase circuit with its equivalent circuit, the current limiting characteristics of the integrated three-phase flux-lock type SFCL were analyzed
