COMMON CHARACTERISTICS 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. For each power equipment major requirements with respect to those three common characteristics and the state-of-the-art are shown. The Technical Brochure is also addressed to all those readers who are so far not familiar with superconducting power equipment but interested in more information about the fascinating possibility to apply compact, efficient and powerful power equipment in future energy systems.
