Abstract: Provided is a trace gas measurement apparatus for electrical equipment that includes at least one sample cell configured to collect an oil sample from the electrical equipment. The sample cell having an oil receiving portion for receiving an oil sample, at least one perforated or porous sheet within a head space thereof for receiving the oil sample from the oil receiving portion, housing the oil sample thereon, and separating a new oil sample received from an existing oil sample within the at least one sample cell. The trace gas measurement apparatus also includes an oil pump for selectively pumping oil into and out of the sample cell, and a control module controlling operation of the oil pump, to adjust an oil level and air pressure within the sample cell, for performing an extraction process of trace gases within the oil sample.

Abstract: A system for analysis of at least one analyte gas present in an insulating fluid of an electrical transformer includes a gas sensor in operational contact with at least one analyte gas from an insulating fluid to provide multiple responses from the sensor. One or more processors are configured to receive the multiple responses during exposure of the sensor to the analyte gas from the insulating fluid representative of a concentration of the analyte gas present in the insulating fluid. The processors are configured to select one or more responses of the multiple responses that provide rejection of interfering gases, resolution between gases, improved low detection range of the analyte gas, improved high detection range of the analyte gas, improved response linearity of the analyte gas, improved dynamic range of measurements of the analyte gas, or one or more combinations thereof compared to non-selected responses from the sensor.
