FIELD: physics.
SUBSTANCE: invention relates to equipment for measuring physical properties of materials and can be used in moisture analysis of insulating liquids, motor and transformer oils and other solutions in various industries. Method for moisture content measurement of spent transformer oil is performed by coulometric Karl-Fischer titration. At that, the sample of transformer oil is exposed to the following action of microwave radiation (UHF-radiation) with power of 1000 W for 40 minutes, and moisture content is measured before and after treatment. Difference between measurements will be absolute moisture content.
EFFECT: excluding the influence of foreign impurities and improving the accuracy of measurement results.
