Historically, gaz sf6 has been applied by utilities in high-voltage systems above 38 kV. Over the course of the past several years, there has been a trend toward application of sf6 gas based gas insulated switchgear applied in industry. Many designs are now available at 38 kV and down to 5/15 kV class. Because the practical system voltage at the point of

Sulfr hexafluoride Analyzer Measures Purity, CF4, HF, Dewpoint and SO2 | TD

Nov 01, 2011. EMT Americas -EMT, dba EMT UK Ltd, has released the AsserolyzIR- multi-gas sf 6 Asset management analyzer. This is an accurate and repeatable field analyzer for insulating gas, using new, patented NIDR technology to measure sf 6 purity, CF4, HF, dewpoint and SO2 (electrochemical). Faced with new regulations from EPA and CARB, and with the global emphasis on reducing Sulfr hexafluoride emissions, EMT took on the challenge to bring the laboratory to the field.
