2,6-di-tert-butyl-p-cresol (DBPC) and 2,6-di-tert-butyl phenol (DBP) are commonly used in transformer insulating oil as antioxidants. Transformer insulating oil is often exposed to high temperatures due to the high voltage electrical applications for which it is commonly used. As

Next, the contractor will typically add a concentrated solution of DBPC inhibitor into the oil stream that is returning to the transformer. This process must be monitored to assure that the

  • What is DBPC in transformer insulating oil?
  • 2,6-di-tert-butyl-p-cresol (DBPC) and 2,6-di-tert-butyl phenol (DBP) are commonly used in transformer insulating oil as antioxidants. Transformer insulating oil is often exposed to high temperatures due to the high voltage electrical applications for which it is commonly used.
  • How DBDs and DBPC affect transformer oil?
  • The effect of DBDS and DBPC on transformer oil is evaluated, which are leading to the insulation failures. These failures are the result of deposition of copper sulfide that is formed by the reaction of copper and these antioxidants.
  • Is DBPC a suitable oxidation inhibitor for transformer oil?
  • DBPC is flammable in nature. It is one of the suitable oxidation inhibitor for transformer oil . The effective life of the equipment is prolonged with DBPC inhibited oil. The formation of copper sulfide increases with the increase in concentration of antioxidants Dibenzyl disulphide (DBDS) and 2, 6-ditertiary-butyl-para-cresol (DBPC).
  • Which spectra can be used to identify DBPC in transformer oil?
  • In addition to the 3650 cm-1 band which may be used for quantification, there are bands mentioned by ASTM D2668 which may be used to identify which antioxidant is present. These are 745 cm-1 for DBP and 860 cm-1 for DBPC. The blank-subtracted calibration standard spectra of DBPC in transformer oil are shown in Figure 2. Figure 2.
  • What is the difference between DBPC and DBP?
  • DBPC is short for 2,6-ditertiary-butyl paracresol and DBP is abbreviation for 2,6-ditertiary-butyl phenol. The rate at which oxidation inhibitor levels in insulating oils become depleted is dependent upon several factors. The temperature of the oil, amount of oxygen contents, soluble contaminants in the oil, and catalytic agents in the oil.
  • What are the oxidation inhibitors in transformer oil?
  • The phenolic antioxidants 2,6-ditertiary-butyl paracresol (DBPC) (also known as butylated hydroxytoluene (BHT)) and 2,6-ditertiary-butyl phenol (DBP) are the two most common oxidation inhibitors added to the electrical insulating (transformer) oil and mineral oil based lubricants.
