8. Conclusion

By satisfactorily freeing electricians from the strong and harmful constraints of fault currents, the superconducting fault current limiter is of interest to electricity producers and distributors. It brings not only technical benefits (improved power supply, voltage wave and stability), but also economic advantages, for example by reducing oversizing or eliminating the need for power transformers, provided their cost is not too high. The efforts made by electricity distributors in numerous projects bear witness to this.

These superconducting limiters have reached a certain degree of maturity and can be considered pre-industrial. The successful experience of prototypes installed in power grids, even over long periods (7 years in Germany for the AMPACITY project), confirms the interest and strong potential of this highly innovative technology.
