SF6-alternatives Leakmate for high voltages

SF6-alternatives Leakmate for high voltages

Sulfur hexafluoride (SF6) is commonly used in electrical insulation networks due to its superior dielectric properties. However, it possesses a high Global Warming Potential (GWP) of 22,800 times compared to CO2 (at equal mass over a time span of 100 years) and a high atmospheric lifetime. This alarming metric prompted

  • Alternatives to SF6 in HV circuit breaker insulation

    Koch (2003) explains that because of SF6’s low dissociation temperature and high dissociation energy, SF6is an excellent arc quenching gas. When an electric arc cools in SF6, it remains conductive to a relatively low temperature, thus minimising current chopping before current zero, and thereby avoiding high over voltages.
