A gas analysis system for analyzing dissolved gas in electrical insulating fluid includes a trap that selectively captures or releases one or more gases, a temperature control device for controlling a temperature of the trap that determining whether the trap is in a gas capture mode or a gas release mode, and a gas sensor for analyzing the gas that was not selectively captured by the trap. The trap may be heated to a first temperature that enables the gas to be adsorbed by the trap, and the trap may be heated to a second temperature that enables the gas to be desorbed by the trap. The gas analysis system may further include a gas flow diverter for directing gas flow past the trap. The captured or released gases may be interfering matrix gases. A method and analyzer for analyzing dissolved gas in an electrical insulating fluid are also disclosed.

System and method for analyzing dissolved gas in electrical insulating fluid

A gas monitoring apparatus and system that provides for reliable and accurate monitoring of gaseous hydrogen and other compounds in dielectric oil. The apparatus provides an environment for and is used in conjunction with metal oxide semiconductor sensors. Thermal conditioning zones for oil provide an environment in which variations in oil temperature and ambient temperature are eliminated to insure that analytical data are not affected by these environmental conditions.

A method for extraction of gas from liquid provides for reliable and accurate extraction of gases dissolved in fluids and routing the extracted gas to an analytical instrument. An extraction module comprises one or more fluorosilicone membranes molded into the shape of a flattened disk. The membranes are retained in a housing in a spaced apart relationship. The membrane is permeable to target gas(es), but not to the fluid. Porous support members support the membranes and prevent damage to them and the housing defines separate fluid flow paths for the fluid and the gas extracted from it. Fluid is passed over the membrane in a first fluid phase; target compounds in the fluid diffuse across the membrane to a second fluid phase until equilibrium is achieved.

Apparatus and method for extracting gas from liquid

A tubular membrane extractor column is connected to an oil filled electrical component such as a transformer. Fault gases dissolved in the transformer oil are extracted from the oil in the separator and are isolated in a second phase. Oil and second phase gas are circulated in separate flow paths until equilibrium is reached. Equilibrated gas is routed to a gas chromatograph or other analytical instrument requiring controlled fluid flow, and which incorporates a manifold assembly that eliminates the need for many of the external fittings and connections required in the instrument. A manifold block has plural fluid flow paths formed therethrough to route fluids to selected components. A collar mates to the block and adapts to a rotary injection valve to provide the continued fluid paths from the block to the injector valve and the other components of the instrument.
