Recent advance and future in development of high temperature superconducting power technology

The high temperature superconductors (HTS) have been developed for use in the electrical power applications. Some demonstration devices based upon HTS such as transmission cables, transformers, fault-current limiters, motors and magnetic energy storage have been built and tested. It is foreseen that superconducting technology will be the prevailing high technology of 21 century. The activities in the development of high temperature superconducting power applications are summarized and thinking on the applications of superconducting power technology in future is also presented in this paper.
