The self fied effect on the power-law index of superconducting cables    [PDF]

A. Anghel

It is shown that in the absence of inter-strand current redistribution the self-field effect is to always increase the power-law index of the volt-ampere characteristic and to decrease the temperature and magnetic field derivatives of the critical current line. We show that the take-off limit of a strand in a cable made of insulated strands is equal to that of a free strand due to a compensation effect between the increase of the power-law index and the decrease of the magnetic field derivative of the critical current.
