Critical comparison of SF ₆ alternative insulating gases and their potential for replacing

The consolidation of SF6, as an insulating gas over the years in electrical distribution and transmission systems, has aided in safety and space occupation, while providing great arc quenching and reliability in medium and high voltage equipment. Aside from its exceptional dielectric properties, SF6is extremely harmful environmentally. Using the Global Warming Potential index, which shows the quantity of infrared thermal radiation a gas absorbs after being released into the atmosphere over a certain period of time, SF6amounts to 23.500 units. Inevitably so, alternative gases need to be proposed. Therefore, this research article presents and compares suitable, more environmentally friendly, alternative gases to SF6.
