Furfuraldehyde (FFA) is produced in transformer oil by the thermal degradation of the paper insulation utilised in power transformers. Measuring the concentration of FFA gives a reliable indication as to the condition of the paper insulation. The authors report on an optoelectronic instrument constructed for the determination of FFA concentration in oil at the site of the transformer. The instrument can measure 0.1 ppm of FFA in transformer oil.
