Measuring Antioxidant Inhibitor in Transformer Oils
Monitoring the degradation of the antioxidant in transformer insulating oil can result in substantial savings by extending the service life of the oil and by slowing down the transformer aging process. 2,6 ditertiary-bytyl paracresol (DBPC) and 2,6-di-tert-Butyl Phenol (DBP) are common inhibitors that prevent oxidation of the electrical insulating oil in transformers. ASTM Method 2668 specifies ...
