gaz sf6-Purity-Meter - GA50 - WIKA South Africa

Description. The WIKA SF 6 -Purity Meter is a cost effective way to determine if the SF 6 percentage in SF 6 -filled equipment meets the requirements. Tolerable limits are suggested by the cigré SF 6 -Recycling Guide and the IEC 60480 for used gas. Measuring the SF 6 -concentration the SF 6 -Purity-Meter indirectly measures impurities of the tested SF 6 -gas like air and CF4.

Sep 01, 2016 · Sulphur hexafluoride (SF 6) is a non-toxic, odourless gas with unique electrical properties. For over 50 years, it has been used in high-voltage gas-insulated switchgear (GIS), where its excellent dielectric and arc-quenching properties make it an ideal insulating gas for medium- and high-voltage equipment. However, when the gas decomposes, it forms decomposition products that are toxic to maintenance personnel and harmful to equipment.

Frequently asked high voltage circuit breaker testing

Most manufacturers don’t recommend Power Factor testing sf6 gas dead tank circuit breakers. To check the quality of the gaz sf6 gas i.e. the insulation of the CB, it is recommended to perform a moisture and purity test on the insulating gas gas. There have been some reports that you can determine some issues within the CB contacts with a Power Factor test, so several utilities still promote and perform these tests on gaz sf6 circuit breakers.
