Analysis of the optical spectra of transformer oils in range 850 - 1000 nm

Abstract

In the present manuscript the results of the analysis of structural-group composition of transformer and turbine oils are described based on optical spectra in the range of 850 - 1000 nm. It is shown that in the course of oil aging portion of CH2 groups decreases, CH3 groups increases slightly, CH groups increased significantly. The components from additives is observed in turbine oil spectrum.
