FIELD: transformer oils.
SUBSTANCE: invention is intended to determine the moisture content of transformer oil. The substance of the invention lies in the fact that the integrated intensities of signals from water in oil and from an internal standard are compared in proton NMR spectra, while using a selective radio frequency pulse in the range of 4-5 ppm and the spherical shape of the ampoule of the inner insert with the standard.
EFFECT: reducing time and improving the accuracy of determining water in transformer oil.
