Ação adsorvente da bauxita sobre óleo isolante novo

Abstract

Recebido em 18/5/04; aceito em 29/9/04; publicado na web em 17/2/05 ADSORBING ACTION OF BAUXITE ON NEW INSULATING OIL. Samples of new insulating mineral oil, after contact with bauxite, were analyzed by visible spectrophotometry, impedance spectroscopy and their total acidity index was measured. The results of these analyses were compared to samples of new insulating mineral oil, which had not been in contact with bauxite. The comparison demonstrated that the bauxite didn't reduce the insulating capacity of the mineral oil and thus could be used to treat the oil in situ during the operation of an electric transformer.
