Effect of Air Ingress on Decomposition of C<sub>4</sub>F<sub>7</sub>N Gas Mixture Exposed to Electric Arcing
This study investigates the impact of breakdown events on the decomposition of C<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf>F<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">7</inf>N-based gas mixture, both in its non-contaminated state and when contaminated with atmospheric air at elevated level. GCMS analysis reveals that the presence of atmospheric air ingress leads to a decrease in the counts of gaseous by-products in comparison to noncontaminated gas mixture, without the generation of new byproducts. This study also examines the effect of breakdown events, finding an increase in concentration of known byproducts without emergence of new by-products. These results suggest that elevated atmospheric impurity levels do not induce further decomposition of the gas mixture under electrical arcing applications.
