ABSTRACT:
Method and apparatus is disclosed for extracting and analyzing gas from a body of liquid such as oil in an electrical transformer. The oil is continuously moved by thermosiphonic action through a conduit in which a gas permeation cell is mounted. Oil within the conduit is air cooled to create a temperature gradient relative to the body of liquid for establishing the thermosiphonic movement. The permeation cell comprises a semi-permeable membrane supported about an elongate porous tube mounted concentric within the conduit so that gas contained within the liquid permeates through the membrane and into a chamber within the cell. An inert carrier gas is injected into and out of the chamber for carrying the permeating gas to a gas detector-analyzer unit.
