Measuring Antioxidant Inhibitor in Transformer Oils

From Wilks Enterprise, Inc.
 

 
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 ditertiarybytyl paracresol (DBPC) and 2,6-di-tert-Butyl Phenol (DBP) are common inhibitors that prevent oxidation of the electrical insulating oil in transformers. Periodic testing is typically not done as often as it should because of the time and expense involved to transport samples to a laboratory. The InfraCal Filtometer is an inexpensive, easy to use field analyzer that would not only encourage more frequent testing but also allow tests to be made on-site with a substantial cost savings over laboratory analysis.
