  • DGA Monitors Using Gas Chromatography (GC) Measurement

    Avoid interference from “Other” SpeciesCalibration Gas For Lifetime AccuracySensitivityGas Extraction MembranesColumn LifetimeMaintenance CostsThe separate‐and‐measure approach is well suited to DGA applications because transformer liquids, and gas samples extracted from them, often contain compounds other than the gases of interest. These “other” compounds can include heavier hydrocarbon gases, alcohols, acids, SF6(leaked into the dielectric fluid from gas insulated bushings, for example), among others. As depicted in red in Figure 1, a well‐designed GC system for DGA will separate the signals of the gases of interest from the signals of “other” compounds, so that the accuracy of the DGA measurements is not compromised by the presence of these “other” compounds. By comparison, DGA measurements based on infrared absorption spectroscopy (including NDIR, PAS, FTIR, etc.) do not separate the gas species, but rather estimate the gas concentrations by measuring the IR absorption of a mixed‐gas sample. When the “other” compounds are present in the extracted gas sample, they can interfere with the IR measurements by causing unkno...
