Sulphur Hexafluoride (SF6) emissions: Electricity ... Hexafluoride (SF6) emissions: At-a-glance summary In 17/18 all three transmission operators outperformed against their target emissions levels of SF6. Scottish Hydro Electricity Transmission's leakage rate is, again above the target figure and will therefore be penalised under the incentive mechanism, although the level is marginal.
Is SF6 Dissolved in Your Transformer Oil? - Doble ...· A gas detector can be used to locate outboard SF 6 leaks, but how can one know if SF 6 gas is leaking through a bushing seal into the main transformer tank? Records from our dissolved gas analysis (DGA) laboratories indicate that approximately 0.3% of oil samples in North America contain traces of dissolved SF 6 gas.
