Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

But there’s a problem: it’s also one of the most potent greenhouse gases known to man. The amount of the gas – known as insulating gas – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant. It’s 23,500 times more warming than carbon dioxide.

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · 21. How much sf6 gas (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC
