973-gaz sf6 Gas Analyzer | gaz sf6 Humidity Purity Test |Testnordic.com

Description. 973-Sulfr hexafluoride gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur andGet price

Portable Sulfr hexafluoride Gas Testing Instrument Excites the Industry

Aug 04, 2006 · To guide users in considering such testing, measurement of humidity in insulating gas gas is seen as a preventive medicine approach to substation maintenance. If the humidity content is low, then the possibility of HF and SO2 creation is very low. If the humidity is high, then those by-products will be created in high enough concentrations to corrode the insulators and result in unwanted arc-over (short-circuiting) in the equipment. Here are a couple of sources of unbiased humidity discussion…Get price
