Summary

A "model conductor", composed of test strands with various surface conditions, is used. The contact resistance is educed by comparing the measured transverse field loss in the model conductor with the numerically calculated value. The interstrand coupling effect increases the coupling loss of a cable-in-conduit conductor with a multi-stage twisting structure. The authors' measurement shows that the current distribution in a twisted conductor for alternating current uses is uniform among the strands. Extension of their estimates provides the basis for analysing the current sharing problems involving thermal effects caused when the conductors are quenched.
