As the cellulosic insulation in a transformer ages, oil soluble byproducts of the cellulose chain called furanic compounds are produced. High concentrations of 2 furfural, the predominant compound, are a clear indication of cellulose degradation, as this is the only type of material in transformers that yields this byproduct.
