【Abstract】 AC losses is one of the critical issues on the development of High T c superconducting transmission cable. In this paper, a kind of electrical ac losses measurement method with lock in amplifier and the ac loss of the one meter long high temperature superconducting transmission cable are presented. The result show that the ac loss of the cable is 0.22 W at operating current 600Arms, 50Hz ( Equal to 0.368W/kA·m), which is much better than designed value 1.0 W/kA·m.更多还原
