Abstract
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.
