Comparison of Peak Current Limiting in Two Magnetically Coupled SFCLs Using Dual Iron Cores

In this paper, the peak current limiting characteristics of a superconducting fault current limiter (SFCLs) using dual iron cores were compared with each other. Two magnetically coupled SFCLs were connected in parallel or series between the two coils. The peak current limiting and the recovery characteristics of these SFCLs could be varied depending on design conductions such as the winding direction and the inductance ratio between the two coils. Through the fault current limiting and the recovery experiment, the peak current limiting effect and the recovery characteristics for these SFCLs were definitely explained.
