Dielectric and Thermal Properties of Supercritical Fluids
In high voltage power networks, there is an ongoing discussion about replacing the dominating insulating medium – Sulphur hexafluoride (SF6). A large amount of research has been conducted to find new insulating media, but no promising alternative has been found yet. This project invests a new medium for high power switching: supercritical fluid. To investigate the breakdown capabilities of SCF, a high-pressure chamber is designed for this purpose. Based on the relevant experiment results, we expect that supercritical fluids have the potential to satisfy the requirements of switching medium.
