Abstract
Automated gas chromatographic apparatus is utilized to analyze various gases dissolved in the insulating oil of an oil-filled power transformer in an expeditious and reliable manner. A sample of the insulating oil is introduced into a sample loop via a sampling valve, from which it is propelled by an inert carrier gas into a degassing chamber comprised of a vertically oriented tube packed with spherical packing elements. The carrier gas sweeping upwardly through this tube strips the various gases out of solution for conveyance by the carrier gas in plug flow fashion to a gas chromatograph where the stripped gases are separated and individually analyzed.
