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.
