This paper presents the results of a study of the behavior of an antioxidant additive (ionol) in insulating oil from existing high-voltage equipment. Decomposition products of the inhibitor (ionol), the concentration of which changes as the oil ages, were found in the oil samples. These compounds can be attributed to impurity compounds, which can also serve as additional markers of aging of a liquid dielectric. The ionol degradation products were analyzed by gas chromatography with a flame-ionization detector (FID) and a mass spectrometric detector (MSD). The advantages of the gas chromatography-mass spectrometric method over gas chromatography with an FID are shown. Compounds that are formed as the oxidation inhibitor (ionol) is consumed are identified using chromatography-mass spectrometry. It has been found that the ionol concentration decreases as the mineral oil ages. At the same time, the concentration of ionol "metabolites" increases and becomes much higher than the concentration of the additive itself. [ABSTRACT FROM AUTHOR] |
