“…They are promising devices to become one of the first large scale commercial application of hightemperature superconductors (HTS) in the industry to achieve higher stability and reliability of electrical power grids [1][2][3]. As coated conductors (CC) are now produced with high critical current, long length and as their prices should drop in the future, CC appear to be well suited for FCL manufacturing [4,5]. The ideal conductor for FCLs needs to transit rapidly and homogeneously to the normal state.…”

A fundamental understanding of the quench phenomenon is crucial in the future design and operation of high temperature superconductors based fault current limiters.The key parameter that quantifies the quenching process in superconductors is the normal zone propagation (NZP) velocity, which is defined as the speed at which the normal zone expands into the superconducting volume. In the present paper, we used numerical models developed in our group recently to investigate the quench propagation in coated conductors. With our models, we have shown that the NZP in these tapes depends strongly on the substrate properties.(94 words) 1

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 (NZP) velocity, which is defined as the speed with at which the normal zone expands into the superconducting volume. Recent experimental measurements in YBCO tapes have shown that the NZP velocity in these materials is extremely slow in comparison with theoretical predictions. In the present paper, we compared experimental results with FEM models developed in our group recently. With our models, we have shown that the NZP of YBCO tapes depends strongly on the substrate properties.Index Terms-Fault current limiters, finite element methods, high-temperature superconductors.
