973-sf6 gas Gas Analyzer | insulating gas 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

Frequently asked high voltage circuit breaker testing

Most manufacturers don’t recommend Power Factor testing gaz sf6 dead tank circuit breakers. To check the quality of the insulating gas gas i.e. the insulation of the CB, it is recommended to perform a moisture and purity test on the sf6 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 Sulfr hexafluoride circuit breakers.Get price
