摘要: Superconducting fault current limiters (SFCLs) are emerging as an alternative to limit in AC and DC power systems. SFCLs can perform faster limiting operation automatic detection recovery, regardless of the type fault. In this paper, a laboratory-scale prototype SFCL was fabricated analyzed for its magnetization characteristics due magnetizing according change number windings pairs. This bridge consists two high-Tc superconducting (HTSC) elements on one iron core. When coils were changed pairs, variation induced voltage Joule losses current, magnetic flux each winding, compared with other. Through comparative analysis, it confirmed that size turns should be considered reduce while effectively during cycle.
