“…In the case of SFCL using low temperature superconducting materials (LTS) such as NbTi alloys [5]- [6], very successful projects have been carried on before the manufacturing of high temperature superconducting materials (HTS) with reproducible quality. Nonetheless, despite the cost of NbTi alloys into the superconductivity market is very competitive, in general, LTS SFCL seems not be possible to be commercialized due to the high cooling cost and the difficulties to manage a cryogenic system with a nearly zero helium loss.…”

Abstract-In recent years, major industrialized countries have began to be concerned about the need for developing strategies on the integration and protection of the growing power capacity of renewable source energies, attracting back their interest on the development and understanding of superconducting fault current limiters (SFCL). The reasons for this are simple: a SFCL may offer a rapid, reliable and effective current limitation, with zero impedance during normal operation, and an automatic recovery after the fault. Nowadays, most of the R&D projects have turned towards to the study of the resistive type SFCL due to their potential to be small, and the likely decrease in price of 2G coated conductors. Thus, in this paper we provide an updated review on the state of the art of resistive type SFCL, emphasizing on the different approaches for the numerical modelling of their local physical properties, as well as on the already tested experimental concepts. Comparison between the properties and characteristics of different resistive-type SFCL using different superconducting materials is presented.

“…However, it is not easy to limit the fault current effectively according to its amplitude because of its instantaneous limiting characteristics using the quench of the superconducting (SC) modules comprising the SFCL. Among one of the developed SFCLs [4][5][6][7][8], the flux-lock type SFCL has been shown to have the merit to easily adjust the operational current and the limiting impedance of the SFCL by setting both the winding direction and the inductance ratio between two coils [8][9][10]. Recently, the SFCL model with the peak current limiting function using two separated SC modules has been suggested and their effective current limiting characteristics have been described [10][11][12].…”

-The current limiting characteristics of the flux-lock type superconducting fault current limiter (SFCL) using series connected two coils with twice triggering operation, which consists of series connected two coils and two superconducting (SC) modules with the inserting resistance, was analyzed. The feature of the suggested SFCL is that it can limit the fault current by triggering either one SC module or two SC modules comprising the SFCL depending on the amplitude of the fault current. To verify the current limiting operation of the suggested SFCL, the short-circuits in the fault location with the different fault currents were tested and its useful operations were described through the analysis on the tested results.

“…Numerous studies for reducing the fault current, including those that applied a superconducting fault current limiter (SFCL) have been conducted [1][2][3][4][5]. Among the developed SFCLs, in the magnetic flux-lock type SFCL, the magnetic flux that is generated from the two coils offset each other during normal conditions.…”

-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.
