Study of optimal temperature during adsorption cleaning of transformer oil under conditions of long-term operation

The article presents the results of an experimental study of the optimal temperature of a transformer under conditions of long-term operation during adsorption cleaning. The study was conducted on five types of samples of used transformer oil with a long service life.Cleaning of each sample of used transformer oil was carried out at temperature ranges of 20 - 80 °C. Silica gel and zeolite were used for adsorption purification. The conducted experimental studies and analysis of the obtained data showed that the optimum temperature for heating the used oil in the process of adsorption purification is 80°C. Regression equations have been obtained that make it possible to determine the dependence of the oil breakdown voltage on the oil temperature after cleaning with adsorbents. These equations will allow you to predict the expected outcomes without having to perform experimental tests
