The transport current redistribution between the core layers on the modelsof HTS cables

The multilayer conductors with insulated and non-insulated layers are analy zed. The space-time current redistributions between the layers of the condu ctor are investigated for the next parameters: values of electric resistanc e at the current leads, transverse contact electric resistance between the layers, the model length, time, the conductor dimension, the current-its pe ak value, the change law and the ramp of the total current input. Most of t he published test results for short (from 1 to 10 m) conductor models do no t reflect the true current distribution of the real long length cable condu ctors. The criterion of experimental model constructions and, in particular , the calculation of its minimum length are presented. The calculations dem onstrate the electromagnetic processes in real cable conductors. (C) 1998 E lsevier Science B.V. All rights reserved.
