    DGA Course –e-lesson #9: Recipes for preparing in-house gas in oil standards

    Course: Master’s level

    Hosted by: Marius Grisaru / Master's level

    This lesson covers the importance of calibration and standards in dissolved gas analysis (DGA) for transformer maintenance. Marius Grisaru explains the need to calibrate each step of the DGA process, from oil sampling to gas quantification. He highlights the limitations of commercial gas in oil standards and the benefits of preparing in-house gas in oil mixtures for accurate calibration. The presentation delves into the challenges of achieving low detection limits and ensuring repeatability, reproducibility, and accuracy in DGA measurements. Marius emphasizes the impact of human factors and analytical performance on DGA diagnosis, urging software developers to understand these limitations. The lesson concludes by providing recipes and methods for creating reliable in-house gas in oil standards to improve the quality of DGA results.
