An imbalance in the transport current among the strands of a Cable-in-Conduit conductors (CICC) can be associated with the change of their performance. In order to understand and improve the performance of CICC's, it is essential to study the current imbal ...
A simple 0D analytical model for the prediction of the take-off point observed in critical-current or current-sharing tests in cable-in-conduit conductors (CICC) is presented. This may be referred to also as the quench point and defined as the point where ...
This set-up is particularly simple and makes possible the use of a flexible cable that may be plugged to the instrument using connectors for easy field applications. Measurements of AC and DC currents are demonstrated. ...
The finite element method has been employed in order to simulate the behaviour of a HTS cable for transport current applications. The E-J model includes an anisotropic dependence of the critical current density Jc and power index n on the local magnetic fi ...
In typical power applications, Bi-2223 conductors carrying ac current will be subjected to external magnetic fields, whose orientation and conductor’s geometry are of major significance for the ac loss magnitude. This paper investigates the influence of th ...
A high order finite difference scheme is introduced to deal with thermo-hydraulic quench simulation in superconducting magnets, specifically in the case of cable-in-conduit conductors (CICC). Liquid helium flow in CICC is governed by the unsteady convectio ...
The aim of this work is to determine the existence and degree of the current unbalance of two types of Cable-In-Conduit Conductors (CICC) of the SeCRETS long sample experiment, and its influence on the conductors' performance. The self-field,measurements a ...
The German SUpraLeiterTest ANlage (SULTAN) test facility at the Centre de Recherches en Physique des Plasma (CRPP), Villigen, is a worldwide unique tool to test high current superconductors over a broad range of operating conditions. The key component of t ...
Due to the turning on or off operation of the circuit breakers and the disconnected switches, a strong electromagnetic interference in gas-insulated substations (GIS) is commonly generated. The transient wave process with a very wide frequency range can ge ...
The experiments of Cable-in conduit conductor (CICC) short samples with high proportion of segregated copper strands have been carried out in SULTAN facility last September. These experiments aimed to investigate transient stability and AC losses of CICC c ...
