Power Applications of High‐Temperature Superconductors

MAR 01, 1996

High‐T_c superconductors show promise for bulk applications from transmission cables to high‐field magnets.

Ten years after Georg Bed‐norz and Alex Müller discovered the first high‐temperature superconductors, and nine years after superconductivity was found with a transition temperature higher than that of liquid nitrogen, considerable progress is being made in bulk applications of high‐temperature superconductors. Electronics applications and thin‐film technology are even more advanced. (See PHYSICS TODAY, March 1995, page 20.) Among the first bulk applications are: current leads, fault current limiters, and wire for power transmission cables.
