Resistivity of REBCO tapes in overcritical current regime: impact on superconducting fault current limiter modeling

Bertrand Dutoit, Bertrand Dutoit, Francesco Grilli, Frédéric Sirois, Nicolo' Riva

A detailed knowledge of the resistivity of high-temperature superconductors in the overcritical current regime is important to achieve reliable numerical simulations of applications such as superconducting fault current limiters. We have previously shown t ...

Analysis of the influence of the normal zone propagation velocity on the design of resistive fault current limiters

Bertrand Dutoit, Bertrand Dutoit, Daniele Colangelo

Commercial high-temperature superconducting coated conductors (HTS-CCs) have low thermal diffusivity and nonuniform critical current density. These two factors lead commercial HTS-CCs to a partial quench when they are subjected to a transport current aroun ...

Finite-element modelling of YBCO fault current limiter with temperature dependent parameters

Bertrand Dutoit, Bertrand Dutoit, Joseph Duron, Francesco Grilli

In this paper we present a 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 finite elem ...

Quench propagation in coated conductors for fault current limiters

Bertrand Dutoit, Bertrand Dutoit, Frédéric Sirois, François Roy

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 zo ...

Design and Production of the ECCOFLOW Resistive Fault Current Limiter

Bertrand Dutoit, Bertrand Dutoit

The European project ECCOFLOW aims at a versatile resistive-type superconducting fault current limiter. For the first time, such a device will be tested at two different sites. The project partners have developed a superconducting fault current limiter des ...
