In this paper, the dual peak current limiting characteristics of superconducting fault current limiters (SFCLs) using dual iron cores were compared to each other. The SFCLs were connected in series between two coils (N 1 and N2). However, the two coils were connected differently to the current source location. The dual peak current limiting characteristics and power burden of these SFCLs could be varied depending on design factors, such as the current source location between the two coils. Using a short-circuit simulation experiment, we compared and analyzed the operating status of the two superconducting elements and their peak current limiting characteristics based on the current source location.
