Research Abstract

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.
