Can we accurately model transformer oil degradation with mathematical equations?

[QUOTE="Windadct, post: 6016612, member: 311008"] "oxidation" per se was not a problem in my experience, but in the USA, most transformers are sealed, elsewhere they may have a conservator and breather via desiccant. In the field we did dielectric and PF (or Tan-Delta - which is a measurement of the Dielectic Constant) using a Doble tests set(on higher Voltage units). But also would sample and return to the lab to have the dielectric, PF as well as Dissolved Gas Analysis - which we did with Gas Chromatography. So moisture was the first issue, then the various issues that cause the oil to breakdown ( Overloading, Hotspots, tracking, corona) -- etc... it is pretty interesting how each cause https://www.netaworld.org/sites/default/files/public/neta-journals/NWwtr09_Hamrick.pdf. Of these the DGA was always the most telling. [/QUOTE]
