In this study, an electric measurement method of AC losses in multi-layer spiral cables was developed. The measurement method was applied to measure the AC loss in the 4-layer spiral cable with 2-layer shield conductor made by Bi-2223 HTS tapes. The measured data were compared with the numerically calculated AC losses and the good agreement was confirmed. Several short model cables made by Y-123 HTS tapes were fabricated by changing tape-to-tape gap width and number of tapes. The AC losses in these short model cables were measured and compared with the numerical data. It is confirmed that the measured AC loss dependences on tape-to-tape gap width and tape numbers were clearly explained by the numerical model. Based on the numerical model, the relationship between the AC loss in the multilayer cable made by Y-123 HTS tapes and the cable geometrical parameters were systematically investigated. Among this study, the useful knowledge for the AC reduction was obtained.

本文研究了多层螺旋电缆交流损耗的电测量方法。将该测量方法应用于Bi-2223 HTS带制作的2层屏蔽导体4层螺旋电缆的交流损耗测量。实测数据与数值计算的交流损耗进行了比较，两者吻合较好。通过改变带间间隙宽度和带数，制备了Y-123 HTS带的几种短缆模型。测量了这些短模型电缆的交流损耗，并与数值数据进行了比较。数值模型清楚地解释了测量的交流损耗与带间间隙宽度和带数的关系。基于数值模型，系统研究了Y-123高温超导带多层电缆的交流损耗与电缆几何参数的关系。在这项研究中，获得了对减少AC的有用知识。
