Evaluation of Transport Characteristics in HTS Conductors with Large Current Capacity by Using an HTS Current Transformer and Miniature Pick-up Coils

为了实现高性能的高温超导发电机和装置，研制低损耗、大载流能力的高温超导导体是必不可少的，因此有必要对高温超导导体的特性进行定量评价。为了评估具有大电流容量的高温超导导体的输运特性，我们完成了一个新的紧凑的测量系统，用于确定具有大电流容量的高温超导导体在各种实验条件下的输运特性。我们的紧凑的系统已被证明是有用的测量交流损耗特性和电流分布特性的大型高温超导导体。

In order to realize HTS power machines and devices with high performance, the development of HTS conductors with low losses and large current capacities is indispensable, and it is necessary to evaluate the characteristics of HTS conductors quantitatively. In order to evaluate the transport characteristics of HTS conductors with large current capacity, we completed a new compact measurement system for determining the transport characteristics of HTS conductors with large current capacity under various experimental conditions. Our compact system has demonstrated its usefulness for measuring AC loss characteristics and current distribution characteristics of large scale HTS conductors.
