Abstract:
In this paper, a new measuring system for the AC loss of High Temperature Superconducting (HTS) tapes and coils was designed, and tested. The system consists of AC current source, acquisition system, power protection system, compensation system, and the measurement is based on the high sensitivity data acquisition card. The power compensation technology and inductance com-pensation technology were applied in this system. The tests on the AC loss of types and coils prove the testing stability and accuracy of the new AC loss measuring system for HTS tapes and coils.
