Description. 973-gaz sf6 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

The Problem with Humidity in Sulfr hexafluoride Gas-Insulated Systems

Sulfur hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of Sulfr hexafluoride gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).Get price

How Humidity Affects the Safety of sf6 gas-Insulated Equipment

When the humidity content of the gas reaches certain levels, the sulfur and fluoride begin to form highly toxic and corrosive products such as sulfur dioxide (SO 2), hydrofluoric acid (HF), and disulfur decafluoride (S 2 F 10). These compounds not only decrease the amount of dielectric insulator but also create an acidic environment thatGet price
