YBCO-based Coated Conductors (CCs) used for applications in Resistive Superconducting Fault Current Limiters (RSFCLs) are well known to have fairly low values of Normal Zone Propagation Velocity (NZPV) during quench avalanche phenomena. Slow propagat

The development of superconducting fault current limiters (SFCL) are mainly based on coated conductors (CC) in spite of the low electric fields the CC can sustain due to their poor thermal behavior and the very low propagation velocities of the norma

The major drawback for the commercialization of fault current limiter (FCL) made of YBCO on sapphire is their expensive price. In the recent years, coated conductors (CC) have been extensively developed and, due to their lower prices, have been recen

A fundamental understanding of the quench phenomenon is crucial in the future design and operation of HTS based Fault Current Limiters (FCLs). The key parameter that quantifies the quenching process in superconductors is the normal zone propagation (

We report on the electrical and thermal characterisation of DyBa 2 Cu 3 O 7 (DyBCO) coated conductors. Detailed I – V curves of these coated conductors are presented showing that the flux flow resistivity of these CC is 2–3 orders of magnitude hi

The adjunction of constrictions along the meander of a superconducting Fault Current Limiter (FCL) greatly improves its behavior thanks to a better distribution of the dissipative zones at the occurrence of a short circuit. This design works perfectl

In this paper, we present a new numerical model, in which both the thermal and the electromagnetic aspects of the over-critical current regime of HTS materials are taken into account. The electromagnetic and thermal equations have been implemented in

To facilitate the up scaling of thin film based fault current limiters (FCL), a complete control of the localization of the dissipated power is needed. This control can be achieved by a new design where constrictions, which are regularly located alon

Geometrical aspects of the design of fault current limiters (FCL) have a great impact on their performances. Recently, the University of Geneva have made certain optimizations by splitting the FCL into many small dissipative lengths in order to achie

The elaboration of Tl-2223 films by a two step process has been investigated. The films contain both Tl-2212 and Tl-2223 phases. We find that the kinetics for the Tl-2212 → Tl-2223 transformation is very slow due to the texture of the Tl-2212 phase
