Temperature rise characteristics of C5F10O/CO2 gas mixture AC high voltage switch bus
High Voltage, Volume 10, Issue 2, Page 325-336, April 2025.Abstract C5F10O/CO2 gas mixture is one of the most promising alternatives to SF6 as an insulating gas in high‐voltage switchgear. As a key performance index in product design, the temperature rise characteristics are rarely reported. In this paper, the thermodynamic parameters of C5F10O/CO2 gas mixture were calculated first. Then, the calculation model
