During the operation of the transformer, Oil suffers from electrics arcs, which, combined to a rising temperature, leads to chemical reactions, generating an aggression on the intern component of the transformer. This internal deterioration produces water due to the cellulose (paper, wood, cardboard) separation. This water then produced, damages the dielectric strength of oil, and can lead to important or irreversible short-circuit for the transformer.
oil treatment is a major operation in the maintenance of the transformer. These treatments can be done with or without the transformer stop and guaranty a controlled- ageing of the transformer. It assures a consistent rate services with the expectation. The treatment involves filtration, dehydration, and the cleaning out of the dielectric oil of the transformer.
Treatment helps to re-establish the quality criteria.
Filtration helps to eliminate the solids particles (paper, steel, copper)
Dehydration helps to extract the water from the oil. The water comes from the deterioration of the cellulose.
The degasification can extract the dissolve gas from the oil. These gases mainly come from the rising temperature created by the electric arcs and partial discharges
