Arc conductance decay is a well-established performance indicator for thermal interruption in SF6, with a narrow range of known limit values. It is also shown that conductance decay can also serve as a performance indicator in CO2-based mixtures, although different limit values for successful thermal interruption apply. In this publication, values of arc conductance 200 ns before current zero are presented for a large number of experiments performed in CO2/O2 90/10 mixture under short line fault-like conditions. These measurements are used to establish limit values for the CO2/O2 mixture, and to investigate the pressure dependence of conductance decay.
