• The Problem with Humidity in gaz sf6 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.

    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 and

    -49,5 °C at 226 kPa (2.26 bar). So when measuring humidity in terms of frost/dew point in the typical SF 6 range (-3…-60 °C) using a chilled mirror hygrometer, there is clearly a risk that an optically detected condensate layer could be SF 6. From a humidity perspective this adds a potentially significant measurement uncertainty,
