Critical current measurement and current distribution for 200 m HTS dc power cable during transport current feeding test

摘要

A 200 m HTS dc power cable test facility was constructed at Chubu University for performance evaluation in 2009 [1], which is called as the CASER-II. We have performed six cooling cycle tests on a 200-meter high temperature superconducting dc power cable system located at Chubu University for performance evaluation. After cooling down to liquid nitrogen temperature, the cable was kept below 77 K by circulation of coolant liquid nitrogen through a cryogenic system and then dc transport currents are applied to the cable for the current feeding tests. In this report, we will present the current distributions and the critical current measurements in the 200 m HTS dc power cable during current feeding tests.
