Abstract
Since the discovery of high-temperature superconductivity, over 30 years ago, there has been great interest in utilising these materials to develop next-generation electric power applications that would replace conventional transformers, cables and motors and generators. There also exist novel technologies enabled by superconductivity, such as superconducting fault current limiters (SFCLs) and superconducting magnetic energy storage (SMES). The high current carrying capacity of high-temperature superconducting (HTS) coated-conductor wires, with zero (DC), or low (AC) losses, enables more efficient devices with smaller footprints and reduced weight. Continual advances in manufacturing techniques have resulted in the commercial availability of long lengths (km+) of high-quality wire from several manufacturers worldwide. This has improved the technological readiness level and commercial attractiveness of such devices.
