1Ac loss in superconducting power cables

Superconducting power cables have been of considerable interest since the discovery of the high Tc superconducting materials [1-7]. Most projects use conductors made of typically the (Bi,Pb)2Sr2Ca2Cu3O10+x (Bi2223) material. Attractive is the larger amount of current and energy that can be transferred using superconductors compared to copper cables an
