On the Stability of Perfluoroisobutyronitrile in High-Voltage Circuit Breaker: A Computational Study.

ABSTRACT: 2,3,3,3-Tetrafluoro-2-(trifluoromethyl) propanenitrile, also known as perfluoroisobutyronitrile (CF4-CN), is the main component of the so-called g³ gas mixture (C₃F₇CN-CO₂-O₂), a proven alternative to SF₆ as an insulating gas in high-voltage circuit breakers. In recent years, numerous experimental investigations have been conducted to identify the principal reactions that this mixture undergoes before and during the electric arcing processes. While thanks to these efforts, several products have already been characterized in different possible experimental conditions, a full picture of CF4-CN reactivity in the high-voltage conditions of circuit breakers has yet to be reached. In this paper, we present a computational study ba
