Abstract

Gas chromatography is employed to analyse gas extracted from dielectric fluid found in an electrical installation. A fluid sample is extracted from the installation through a valve which meters a precise measurement of the fluid. The sample is then applied to a dissolved gas extraction chamber. The gas extraction chamber is next evacuated of air by a pump. The gas so extracted from the dielectric fluid is now applied to the gas chromatograph for analysis and a recording device records the measured constituents of the extracted gas.
