Breakdown performance of vacuum circuit breakers using alternative CF3I-CO2 insulation gas mixture

Article English OPEN
Widger, Phillip; Haddad, Abderrahmane; Griffiths, Huw;

In this paper, sulphur hexafluoride (SF6) insulated vacuum interrupter circuit breakers have been used to explore replacing SF6 gas with a trifluoroiodomethane and carbon dioxide (CF3I-CO2) gas mixture. The search for an alternative insulation gas is driven by the well ... View more
