Abstract

A parallel HTS conductor to flow large current is essential for applications of HTS power device. Non-uniform current distribution in the parallel conductor is caused mainly due to the difference of inductance. There are a contact method which measures current directly and a non-contact method which measure indirectly. But current distribution of each conductor in parallel conductors can not be measured with conventional method. In this paper, we researched a measurement method to identify current distribution of the parallel conductor indirectly with Hall sensors and compared with the analysis results by 2-D FEM.
