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 willGet price

The Problem with Humidity in sf6 gas Gas-Insulated Systems

Chilled Mirror Technology to Measure Humidity in Gas Some of the SF 6 gas in the compartment is routed alongside a mirror to measure the gas’s dew point. The mirror is chilled by a Peltier element until condensation or an ice layer forms. Then an LED light shines on the condensation/ice layer, with its refraction picked up by a photodetector.Get price
