Abstract

The importance of correctly understanding and assessing the interruption capability of gases that have the potential to replace SF

for switching purposes is discussed. Issues relating to the assessment of the interruption capability are addressed. A brief summary is also given to recent industrial tests in the search of SF

replacement gases. The dominant energy exchange mechanisms responsible for the differing interruption capabilities of N

and SF

are analysed using a calibrated arc model. Correlation between the interruption capability and material properties of a number of gases has been established

thus providing theoretic evidence on the selection criteria

for SF

replacement gases in future.
