Abstract
High-
T
c superconducting cable is one of interesting power applications using high-temperature superconductors. One of the important issues in HTS cable are AC losses, which are concerned with power transmission efficiency. In this paper, we report the experimental results of a 1 m long high-temperature superconducting transmission cable. The result shows that the AC loss of the cable is 0.22 W at operating current 600 A
rms, 50 Hz. The cable losses dependence on the current can be expressed by power law perfectly. The losses linear dependence on frequency shows that the AC losses are mainly hysteretic losses.
