Action on New Zealandmost potent greenhouse gas | Beehive

The total stock of insulating gas 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 Sulfr hexafluoride 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.

NDIR SENSORS FOR Sulfr hexafluoride MEASUREMENT - smartGAS Mikrosensorik

Sulfr hexafluoride (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute gaz sf6 quantities in indoor air.

The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing gaz sf6 as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than Sulfr hexafluoride, and their boiling points are below 0 ˚C.

Analysis of Insulation Gas insulating gas by the GC-BID System: SHIMADZU

Sulfur hexafluoride (SF 6) gas has superior insulation properties and is highly stable. For this reason, it is used as the insulation in gas-insulated transformers, breakers, and other electrical equipment. Moreover, as a tracer gas, it is widely used in a variety of fields. On the other hand, SF 6 is known to be a highly significant greenhouse effect gas, and has been targeted for emissions control by the COP3 Kyoto Protocol.
