The superconducting (SC) c u r r e n t limiter is one of the most attractive applications of superconductivity because it is an innovative device without any conventional equivalence. Following the emergence of ultra low a x . loss NtiTi strands in the eighties several devices have been designed and built using these superconductors. The discovery of high T, materials has crizated numerous potential applications such as particularly for current limiters. The operation a t higher temperatures and the very different nature of the SC oxides compared to low T, strands deeply modify the limitation process. We have carried out some experiments to study the transition of high T, samples fed by voltages with the objective of matking a resistive limiter. The quench behaviour of sintered and textured Bi compounds have been studied and compared. Grain boundaries play a very important p a r t in the limitation process. The resistive transition seems to begin a t the grain boundaries. The complete resistive transition of the sample has never been recorded. The propagation of the transition from the resistive part to the entire sample is very low. To overdrive the quench a magnetic field has been applied. In this paper, the results a r e reported to show the grain boundaries role in the transition.

“…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.

“…So the SCFCL appears as a greatly interesting device for the grids. The works about SCFCL started a long time ago with low T c superconductors (LTS-NbTi) [1] then with high T c superconductors (HTS-BSCCO, YBCO, MgB 2 ).…”
