2.2.12 Gas Monitor System The insulating and interrupting capability of the SF6 gas depends on the density of the SF6 gas being at a minimum level established by design tests. The pressure of the SF6 gas varies with temperature, so a mechanical temperature-compensated pressure switch is used to monitor the equivalent of gas density (Figure 2.14).
