ABSTRACT:
A device to monitor dissolved gases in electrical insulating liquids such as transformer oils. The monitoring device includes a sampling means to obtain a liquid sample from the electrical device whose liquid is being monitored, a gas extraction means to extract the dissolved gases from the liquid sample, an injection means to inject the extracted gases into a gas chromatograph, and a gas chromatograph to analyze the dissolved gases to determine the concentration of various dissolved gases.
