The art of transformer maintenance, inspection and repair ...· 4. Transformer liquid and insulation. The task of oil in a transformer is to act as an electrical insulation and to transfer heat from the transformer's active parts into coolers. Oil acts as a good electrical insulation only as long as it is satisfactorily dry and clean.
