ABOUT THE LATEST E-LESSON

Extraction of gases from different types of insulation oils by different processes is the most challenging and least researched process of DGA. For a reliable DGA, it is crucial to have a very good understanding of the nature and consequences of different processes and parameters.

In this e-lesson you can learn how to adapt extraction method to sampling, measurement, transformer type, insulating oils type, how to monitor extraction efficiency by calibration, use of constant physical parameters, calculated parameters etc. We also discuss reliability of each individual method and talk about important differences between IEC60567 and ASTM D3612.
