Quench Simulation of REBCO Cable-in-Conduit Conductor With Twisted Stacked-Tape Cable

Pierluigi Bruzzone, Rainer Wesche, Kamil Sedlák, Davide Uglietti

Quench protection is a critical issue for magnet using high-temperature superconducting (HTS) materials such as REBCO. For cable-in-conduit conductor (CICC) with twisted REBCO tapes, which is considered for high-current HTS conductor for fusion magnet, the ...

Isolated vs. Interconnected Wind Turbine Grounding Systems: Effect on the Harmonic Grounding Impedance, Ground Potential Rise and Step Voltage

Farhad Rachidi-Haeri, Marcos Rubinstein, Antonio Sunjerga, Quanxin Li

Wind turbines are very vulnerable to lightning strikes due to their height, sharp edges and remote locations often with high soil resistivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We ...

Insulation effect on thermal stability of Coated Conductors wires in liquid nitrogen

Bertrand Dutoit, Bertrand Dutoit

Superconducting wires are not perfectly homogeneous in term of critical current as well as stabilization. In resistive fault current limiter applications this could lead to hot spots if the fault current is only slightly above the nominal current of the de ...
