由涂覆导线组成的罗贝尔电缆的三维结构影响其交流损耗特性。交流损耗的测量和数值电磁场分析是使用六股罗贝尔电缆和几个参考导线进行的：单个直涂覆导线，3×1叠层，其中三个直涂覆导线叠置，以及3×2叠叠，其中两个3×1叠置并排放置。对罗贝尔电缆和参考导线的交流损耗进行了实测值和计算值的比较。根据数值电磁场分析得到的超导体内部电磁现象，讨论了超导体的交流损耗特性。在实验和数值计算的基础上，验证了罗贝尔电缆的三维结构对其交流损耗特性的影响。
The three-dimensional structure of Roebel cables consisting of coated conductors influences their ac loss characteristics. Measurements of the ac loss and numerical electromagnetic field analyses were carried out using a six-strand Roebel cable as well as several reference conductors: a single straight coated conductor, a 3 × 1 stack, where three straight coated conductors were stacked, and a 3 × 2 stack, where two 3 × 1 stacks were placed side by side. The measured and calculated ac losses of the Roebel cable and those of the reference conductors were compared with one another. The ac loss characteristics were discussed on the basis of the electromagnetic phenomena inside the superconductors obtained from numerical electromagnetic field analyses. The influence of the three-dimensional structure of the Roebel cable on its ac loss characteristics was verified on the basis of the experimental and numerical results.
