Abstract

The content of the antioxidant additive ionol in mineral transformer oil within the limits of normalized values (0.08–0.40 wt%) provides reliable operation of oil-filled high-voltage electrical equipment. One of the methods of an inhibitor concentration control in a liquid dielectric is gas-liquid chromatography. However, in the option offered by certified methods based on gas chromatography, it is impossible to ensure high accuracy in determining the amount of inhibitor. In order to reduce the analysis processing time, as well as to increase the reliability of the measured concentration of ionol in a complex hydrocarbon matrix of oil, a new method of chromatography mode using the distribution coefficient of ionol in the oil–ionol-solvent system is proposed in this article. In Russia, the most widely used brands of mineral insulating oil are such as GK, TKp, Nytro 10XN, Nytro 11GX, and T-750. The value of the distribution coefficient for the listed brands of oils differs from each other (from 2.30 to 2.61), which indicates the unevenness of the distribution of ionol between the molecules of carbohydrates of different chemical compositions and, in general, because of the chemical composition of various brands of oils.
