“…In conclusion, our experimental results confirm that cracking and hot spots are a major obstacle to the application of bulk HTSs to resistive SFCLs [17][18][19], being necessary to attach a protective shunt layer to the bulk HTS to avoid its cracking.…”

“…Due to their structural advantages, RSFCLs can be built very compact and lightweight, and the continuous drop of prices for 2G coated conductors keeps lowering their manufacturing costs [9,10]. There are many RSFCLs that have been built and tested, showing good performance at limiting short-circuit faults [11][12][13][14][15][16]. However, a few limitations still exist for this technology.…”

The application of resistive-type superconducting fault current limiters (RSFCLs) in electrical networks is very attractive due to their relative compactness, light weight, and good performance. However, this technology still has drawbacks: asymmetrical quench, uncertain limiting velocity, passive action and incapability of enlarging capacity. Here, we present an active quenching technique which can potentially solve these problems. The quenching process is triggered using highfrequency (HF) AC fields, which are generated by two coupled copper coils attached on both sides of the YBCO sample. Our experiments show that this approach is effective in guaranteeing uniform quench and therefore is expected to be able to significantly extend the service life of the device. Moreover, the quench speed can be considerably increased by the HF field. We find that the performance of acceleration is positively correlated to the transport current, intensity and frequency of the AC field. In addition, a DC magnetic field is added around the sample holder simultaneously with the AC field, to study the field-angular-frequency dependence of the quench time t (B AC f AC B DC θ DC ). Experimental results prove that the DC magnetic field can cooperate with the HF AC field to accelerate quench, which means better performance can be produced with lower costs with the two fields acting together. In all, this technique showed outstanding performance regarding quench acceleration and tape protection. We believe the HF-assisted quenching technology has a promising future in current-limiting devices and hope our findings could be helpful for its potential applications.

“…It is well known [4], [5] that RFCLs can allow to couple separate sub-grids doubling the short-circuit power while effectively limiting the current when a fault occurs. In the recent years several project focus on RFCLs [6]- [8]. In particular, EC-COFLOW is the first one where the same RFCL is designed for two different applications: busbar coupler and transformer feeder.…”

Abstract-Due to the energy demand growth and distributed generation (DG) units penetration, a substantial increase of the rated short-circuit current of the electrical lines is expected. As a consequence, the electrical grid infrastructure needs to be extended or drastically renovated. In this context, resistive superconducting fault current limiters (RFCLs) based on high temperature superconducting coated conductors (HTS-CCs) represent a promising technology to limit the upgrading costs. Thanks to recent improvements on HTS-CCs performances, RFCLs are now close to commercial applications. However, as they are novel devices, their real impact on the electricity network remains an open issue. In particular, the subject of this research is to study the grid integration of the RFCL designed within the European project ECCOFLOW [1]. The device has been simulated in two applications in two different typologies of existing medium voltage grids: RFCL used as busbars coupler and RFCL used as transformer feeder. This contribution is the continuation of previous works [2], [3], where the effects of symmetrical and unsymmetrical short-circuits on inhomogeneous HTS-CCs have been extensively analyzed.
