Questions & Misconceptions about GIS SF6 Gas & Systems

2012-2-1 · moisture (water vapor) in the gas begins to condense as liquid (droplets or dew) or solid (ice). Typical dewpoint in SF6 equipment ranges from -60C to -5C. Common operating pressures are 100-755 kPa abs. (0-95 psig). ppmv: Moisture Volume concentration (parts per million by 15 1/18/2012 Volume). One million times the ratio of the volume of moisture

US7257496B2 - Method and apparatus for monitoring …

A method for detecting loss of SF6 gas from electrical utility apparatus determines a molar ratio of gas in a container at an initial time and of gas in the container at a subsequent time. Measurement of temperature is determined by averaging aient temperature and temperature of the surface of the container. The initial values of pressure and temperature define the initial value of n as
