Abstract
Among many alternative gases proposed to replace SF6 as insulating gas, g<sup>3</sup> (green gas for grid), fluoronitril based component officially introduced at CIGRE 2014, can be now used for insulation projects and new environmental friendly circuit breakers. This gas mixture g<sup>3</sup>, presents a reduction of the global warming potential by 98% compared to SF<sub>6</sub> gas and shows quite good dielectric withstand capability. Many new investigations about thermal and chemical behavior have been done and are precised in this paper. Last switching test campaigns will be presented for 145 kV applications. Simulation tools should be updated to be applicable to these projects. Developments and comparisons with last test results will be analyzed.
