Abstract

HTS wires of various structures and synthesizing processes are being developed for power apparatus applications in the Super-GM project. AC transport current losses of four of those wires were measured by an electric method using a lock-in amplifier. Measured wires are a Bi2212 rod fabricated by the laser pedestal growth method, a Y123 tape fabricated by the pulsed laser deposition and multilayered Bi2223/Ag sheathed wires of square and tape shapes. In this paper, based on measured data, dependence of AC transport current losses of HTS wires on their structures and synthesizing processes is discussed.
