SF Maintenance Equipment Fundamentals

Moisture Moisture levels must be kept to a minimum to reduce the formation of acidic by-products, such as HF, SO 2, SOF 2, etc. Hygrometers, or moisture-measuring devices, built to work in the corrosive environment of arced SF 6, will quantify the level of moisture vapor in gas. Because the amount of moisture present in the vapor state will fluctuateGet price

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

Description. 973-sf 6 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
