Abstract

The article discusses the appearance of voltage deviations in the power transmission line as a result of connecting more and more electric consumers with different resistance to the power supply line and the assessment of its negative impact on the efficiency and reliability of power transformers during long-term operation. In the LD DIDACTIC laboratory complex, the connection schemes of the power transformer with a total capacity of 360 VA were changed and the voltage deviation from the nominal value is brought to the supply line. The values of the voltage deviation generated in the power transformer were determined when loads with different resistance is connected to the secondary output terminals of the power transformer. Based on the obtained results, it is possible to evaluate the performance of the power transformer.
