DC performances of ITER NbTi conductors: Models vs. measurements

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

Within the R&D program on the International Thermonuclear Experimental Reactor (ITER) Poloidal Field (PF) coils, a full size conductor sample was tested in the SULTAN facility (CRPP Villigen, Switzerland). This sample is composed of two straight ITER-like ...

Reconstruction of current unbalance in full-size ITER NbTiCICC by self-field measurements

Boris Stepanov

Methods have been developed to study the distribution of the transport current among the strand bundles of cable-in-conduit conductors (CICC) by using self-field measurements with Hall probe arrays. The unbalance in the transport current is mainly caused b ...

Lightning induced disturbances in buried cables - Part I: Theory

Mario Paolone, Emanuel Petrache

In this paper, we present a review of theoretical methods to compute lightning induced currents and voltages on buried cables. The evaluation of such induced disturbances requires the calculation of the electric field produced by lightning along the cable ...

DC performance, AC loss and transient field stability of five medium size NbTi cable-in-conduit conductors with parametric variations

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Martin Vogel

Five medium size NbTi cable-in-conduit conductors with parametric variations in the cable layout were fabricated of three different strands to investigate their DC performance, AC loss behaviour and transient stability by means of the SULTAN facility. A co ...

The index n of the voltage-current curve, in the characterization and specification of technical superconductors

Pierluigi Bruzzone

The attention of the fusion magnet specialists has been drawn in the last years to the volt-ampere characteristic (VAC) of the large cable-in-conduit conductors (CICC), as early voltage was observed in conductor and model coil tests, far away from the expe ...

Lightning electromagnetic field coupling to overhead transmission line networks and to buried cables

Emanuel Petrache

Lightning-induced voltages in power and communication systems are nowadays one of the main causes of power quality and electromagnetic compatibility. In recent years, due to the increasing demand by customers for good quality in the power supply along with ...

Mitigation of Lightning-Induced Overvoltages in Medium Voltage Distribution Lines by Means of Periodical Grounding of Shielding Wires and of Surge Arresters: Modeling and Experimental Validation

Mario Paolone, Carlo Alberto Nucci, Emanuel Petrache

In this paper, we investigate the effect of periodically-grounded shielding wires and surge arresters on the attenuation of lightning-induced voltages. We discuss the adequacy of the commonly made simplification of assuming the shielding wire at ground pot ...

Analysis and interpretation of Tcs tests of the ITER Toroidal Field Conductor Insert

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Luca Bottura

The toroidal Field Conductor Insert (TFCI) coil was tested at 46 kA in the 13 T background magnetic field generated by the Central Solenoid Model Coil. The single layer TFCI coil uses a Nb3Sn cable-in-conduit conductor in a Titanium jacket. The object of t ...

The voltage/current characteristic (n index) of the cable-in-conduit conductors for fusion

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

The index n of the voltage-current characteristic of large superconductors is a crucial parameter to assess the allowed range for coil operation. In the tests of the Insert coils at the CSMC as well as in the short sample test in the SULTAN facility, it is ...

Measurement of lightning-induced currents in an experimental coaxial buried cable

Mario Paolone, Emanuel Petrache

We present in this paper experimental results obtained at the International Center for Lightning Research and Testing (ICLRT), Camp Blanding, Florida, where currents induced by triggered and natural lightning events were measured at one end of a shielded b ...
