我们测量了两层绞合高温超导（HTS）电缆的交流损耗特性的影响的扭曲间距，扭曲方向，和传输电流平衡的内层和外层。为了测量每一层的交流损耗，我们将热电偶放置在每一个具有热绝缘的胶带面上。在HTS电缆中，内层暴露于由扭曲的外层产生的纵向磁场，并且外层暴露于由内层产生的周向磁场。当内层和外层串联时，内层的交流损耗特性表现出外层布置的影响。当内外层的输运电流平衡发生变化时，当内层输运电流超过外层输运电流时，存在最低损耗条件。这些现象是对每一层中磁场的幅度和方向的可能解释。
We measured the influence of the twist pitch, twist direction, and transport current balance of the inner and outer layers on the ac loss characteristics in a two-layer twisted high temperature superconducting (HTS) cable. To measure the ac loss in each layer, we placed the thermo-couples on each tape face with thermal insulation. In the HTS cable, the inner layer is exposed to a longitudinal magnetic field generated by the twisted outer layer, and the outer layer is exposed to a circumferential direction magnetic field generated by the inner layer. When the inner and outer layers connect in series, the ac loss characteristics in the inner layer exhibit the influence of the outer layer arrangement. When the transport current balance of the inner and outer layer changes, the lowest loss condition exists when the inner transport current exceeds the outer transport current. These phenomena are possible explanations for the amplitude and direction of the magnetic field in each layer.
