Comparison of electric and calorimetric measurements of AC losses in HTS wires and bulks

摘要

We developed electric methods to measure total AC losses in an HTS wire carrying a transport current in an AC magnetic field, AC transport current losses in a wire subjected to magnetic fields generated by AC currents in adjacent wires and AC magnetization losses in a bulk. The validity of those methods was investigated by comparison of the data measured by calorimetric methods. In the paper, the electric and calorimetric measurement methods are explained and their validity is discussed based on the experimental data. (c) 2006 Elsevier B.V. All rights reserved.
