Abstract
This paper considers the nucleation and propagation of a normal zone in large composite superconductors, considering the relatively long time of current redistribution in the stabilizer. A model is proposed for treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and the temperature distributions along the conductor. Numerical simulations have been performed of normal-zone propagation for cryostable and non-cryostable conductors, and analytical expressions obtained for the velocity of propagation.
