Analysis of current after normal transition in a cable-in-conduit conductor

When some strands carry a large current as a result of current imbalance, t hey mag initially become normal and the current is transferred to other sup erconducting strands. A one-dimensional simulation code for stability and q uench of a cable-in-conduit conductor is improved to study this phenomenon using an infinitely long distributed circuit model, in which the current ca n easily De calculated, Tile results show the normal zone propagation plays a significant role in Be current decay. Also, they are Indicated that the conductor is more stable for higher conductance but the stability of the co nductor seems more important to prevent instability due to the current imba lance.
