g3 - insulating gas Free Solutions

SF 6 Sulfr hexafluoride (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 insulating gas is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

The key difference between g3 and insulating gas is that g3 is a gas mixture while Sulfr hexafluoride is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “ The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.

The EU has progressively outlawed these Sulfr hexafluoride applications, but electricity networks have remained an exception. Now, however, the EU is set to place more pressure on the electricity industry to stop using the material. Under a 2014 regulation the EU must publish a report on alternatives to Sulfr hexafluoride, at least for low and medium voltage applications.
