摘要: The frequency-dependent critical current of a superconductor strip and Roebel cable has been studied using 2D finite element simulation. It is shown that the increases with frequency as f1/n, where n exponent power law flux creep model. Transport ac loss in decreases f − 2/n when amplitude applied far less than its current. However, large becomes comparable to current, transport 1/f. analytical results are substantiated available experimental data
