Abstract

Japan's first in-grid demonstration of a high-temperature superconducting (HTS) cable system has been started to evaluate its performance, safety and reliability. We developed the cable using the DI-BSCCO HTS wire, and repeated design changes and element testing to meet required specifications. The performance of the cable was confirmed in the preliminary test using a 30-m HTS cable system and it was then successfully installed in Tokyo Electric Power Company's Asahi Substation with associated systems. In October 2012, the cable system was connected to a live power grid and started its operation for a long-term demonstration test.
