Sažetak
Apart from abnormal faults detected by DGA, one of the most important factors in shortening the lifetime of a power transformer is ageing of paper insulation used in transformer construction. The analysis of furans in transformer oil is one of the best techniques to be used in the assessment of the remaining lifespan of a used transformer. This technical article aims to describe the development and validation of an analytical method based on ultraviolet-visible (UV-VIS) absorption spectrophotometry, designed to evaluate the content of 2-furfuraldehyde (2-FAL) dissolved in dielectric oil. This is a technique which, despite not reaching the levels of resolution of the more commonly used high-resolution liquid chromatography (HPLC), provides greater efficiency in terms of utilisation of resources, both financial and manpower.
