Introduction of CIGRE WG D1.64 and topics on insulation issues on superconducting cables and fault current limiters

摘要

Research activities on electrical insulation systems at cryogenic temperatures have started in CIGRE WG D1.64 since April 2016. The scope of CIGRE WG D1.64 is to study the fundamentals and applications on electrical insulation techniques for superconducting power apparatus and other applications to be operated at cryogenic temperatures. In this paper, the research activities of CIGRE WG D1.64 are introduced. In addition, as the latest topics on electrical insulation systems at cryogenic temperatures, dielectric characteristics peculiar to superconducting cables and superconducting fault current limiters are introduced.
