Dielectric and Life Cycle Behaviour of a Cryogenic Insulation System
Since the discovery of high temperature superconductors (HTS) in 1986 several applications for power equipment were developed. The critical temperature of the used ceramic HTS (up to 110 K) lays over the boiling point of liquid nitrogen (77 K), which is used for cooling down to the operating temperature and as insulating medium. Because of this different specifications compared to conventional insulation systems the dielectric and life cycle behaviour of a cryogenic insulation system was analysed .
