摘要：

The DC current distribution and self-field AC losses of three HTS cable models have been measured electrically. Each cable consisted of one or two layers of spirally wound Bi-2223 tape. Non-uniform distributions of the current were found, due to variations in terminal resistances and tape degradation during winding. This meant that caution was required in the placing of leads for measuring the in-phase voltage and in the resultant calculation of AC loss. Three different configurations for the voltage leads were employed and the disadvantages of each are discussed. The calculated AC losses are compared to theoretical models and interpreted, considering the influence of the non-uniform current distribution on the measurements. (C) 1998 Elsevier Science B.V.
