Add to ORKGThe average age of transformers in service is increasing and approaching the end of design life. Hence there is an increasing need to assess the condition of transformers. The utilities currently use a number of diagnostic techniques to assess the insulation condition of aged transformers. Among them physic-chemical analysis of transformer oil are frequently used. The article presents the results of many years of routine laboratory testing of oil transformers operated in the EnergiaPro energy company. Oil testing included measurements of total acidity, water content, breakdown voltage, resistivity, tgδ
