Common characteristic and emerging test techniques for high temperature superconducting power equipment

Many large scale demonstrators and prototypes of superconducting power equipment like cables, transformers, rotating machines, current limiters and energy storage devices have been built and successfully tested in the past and cables and medium voltage fault current limiters are already commercially available. Nevertheless, there is a need to further improve and develop common characteristics for this equipment like superconducting materials, electrical insulation and cryogenic insulation and cooling because these are essential factors for the successful development and reliable operation. This brochure summarizes common characteristics, test techniques and state-of-the-art for high-temperature superconducting materials, cryogenic electrical insulation and cryogenic insulation and cooling.…
