A method and apparatus for providing cryogenic cooling to HTS devices (24) in , particular those that are used in high-voltage electric power applications. The method involves pressurizing liquid cryogen (46 48) to above one , atmospheric pressure to improve its dielectric strength while sub-cooling the , liquid cryogen to below its saturation temperature in order to improve the performance of the HTS components (24) of the device. An apparatus (10) utilizing such a cooling method consists of a vessel that contains a pressurized gaseous cryogen region (44) and a sub-cooled liquid cryogen bath a liquid cryogen heating (52) coupled with a gaseous cryogen venting scheme (30) to maintain …

Why it's free to use
- Filed June 15, 2004 and granted March 6, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 15, 2024.
