“…On the other hand, the fault current that is greatly increased while the fault occurs may cause saturation of the core because of the increased magnetic flux inside the core, which would reduce the fault current limiting effects of the SFCL. To prevent this, SFCL structures using cores with two magnetic paths or using one core with a third separate coil have been proposed and reported [9][10][11]. However, to date, there is no reported research on the internal magnetic flux characteristics of the E-I core in a peak current limiting structure having a third coil and an additional HTSC element.…”

-In this study, a superconducting fault current limiter (SFCL) having two magnetic paths was proposed, and its current limiting characteristics were analyzed. For the SFCL to effectively perform the current limiting operation, it must be designed considering the magnetic saturation of the E-I core. Further, the influence of the magnetic flux on its peak current limiting characteristics was investigated. In addition, the magnetic flux curves of the SFCL obtained from the fault current limiting experiments were analyzed, and the subtractive polarity winding case was observed to not only further reduce the saturation potential of the core but also perform the peak current limiting functions well when compared with the additive polarity winding case.
