Prediction of quench in cable-in-conduit conductors considering current-sharing effect of copper

A simple 0D analytical model for the prediction of the quench point has been presented by Anghel [Anghel A. A simple model for the prediction of quench point in cable-in-conduit conductors. Cryogenics 2003;43:225–32]. The model offered a straightforward approach to estimate the quench behavior of cable-in-conduit-conductor (CICC) and provided a clear view of the relationships between conductor parameters and its quench properties. However, this 0D model did not address the current-sharing effect of copper. In this paper, it was considered by approximation that superconductor and copper form two resistors in parallel, the redistribution of current due to the copper was taken into account. The result of the new model was compared with that of a previous model. The 0D model predicts the quench with a higher accuracy.
