Condition monitoring of the paper winding of power transformers involves the measurement of the concentration of 2-furaldehyde, also called furfuraldehyde (FFA) in the transformer oil. Measuring the concentration of FFA in the oil gives a reliable indication of the condition of the paper insulation. This measurement has routinely been performed by using techniques such as high performance liquid chromatography. We report for the first time the use of fluorescence-based methods for the assessment of FFA in transformer oil
