Abstract

<jats:p>A high voltage gas blast circuit breaker relies on the high speed gas flow in a nozzle to remove the energy due to Ohmic heating at high current and to provide strong arc cooling during the current zero period to interrupt a fault current. The physical mechanisms that are responsible for the hugely different arc cooling capabilities of two gases (SF&lt;sub&gt;6&lt;/sub&gt; and air) are studied in the present work and important gas material properties controlling the cooling strength identified.</jats:p>
