Description
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. 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 or laboratory analyzer that would not only encourage more frequent testing but also allows tests to be made on-site with a substantial cost savings over laboratory analysis. The InfraCal Filtometer is a compact, fixed-filter mid-infrared analyzer weighing less than 5 pounds that can be operated from a battery pack or a cigarette lighter adapter cable. This makes it portable, rugged and operable in a range of ambient conditions typically found in field environments.
An internal calibration table and easy-to-use operator interface allows for analysis by non-technical personnel. The InfraCal’s filter wavelength is as specified by ASTM Method 2668 for the infrared measurement of DBPC and DBP (2.7 µm or 3650 cm-1). As the inhibitor is depleted, the infrared absorbance decreases. The InfraCal Filtometer provides a direct readout from 0.02 to 5.0 percent DBPC or DBP in less than a minute.
