Action on New Zealandmost potent greenhouse gas | Beehive

The total stock of Sulfr hexafluoride in New Zealand in 2002 was estimated by Transpower to be less than 40 tonnes. A detailed study carried out by CRL Energy Ltd on gaz sf6 emissions as part of the 2004 NZ Inventory of Greenhouse Gas Emissions gives a more accurate estimate of the total national stock of 33.2 tonnes in 2003.

Sulfr hexafluoride circuit breaker maintenance | TD Guardian Articles

The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV. As Sulfr hexafluoride breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.

gaz sf6-alternative gases for application in gas-insulated

Mar 20, 2018 · Sulfur hexafluoride (SF 6 ), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases. Recently, this effort has made important progress, with promising alternative gases being identified and tested.
