Abstract

The article proposes a comparative study of the parameters of the equivalent circuits of two-winding oil power transformers with a capacity of 1000 kVA at voltages of 6 and 10 kV. The parameters were determined by calculation using the passport data and the results of the experiments of the no-load and short-circuit modes. The results of the values of active and reactive resistances are presented, during the experiments the values of losses in the no-load and short-circuit modes were studied. Based on a comparison of transformers of different energy efficiency classes, the influence of design solutions and cooling type on the equivalent circuit parameters and energy characteristics has been identified, which allows for the optimization of equipment selection during network design.
