Abstract
This paper deals with the effect of the temperature on the partition of the furanic derivatives between the oil and paper insulation in power transformers. For the five chemical markers studied, due to its highest polarity, the 2-furfurol showed the highest difference compared to the other furanic species. The author's propose correction equations at 20°C for the normalization of the temperature for the furanic derivatives. These correction factors allow following the real trend of the markers during all the transformer life.
