| Outline of Final Research Achievements |
This study has focused on discharges in supercritical carbon dioxide as an alternative medium of SF6 from the environmental viewpoint. The breakdown voltage recovery ratio under supercritical phase was greater than that of liquid carbon dioxide. Furthermore, the recovery processes at supercritical and liquid phases were visualized by a shadowgraph method to elucidate the difference of voltage recovery ratio at both phases.
