THE STUDY OF EQUIVALENT CIRCUITS OF THE TRANSFORMER WITH

STAR-CONNECTED WINDINGS IN PHASE COORDINATES

The authors of this article study some equivalent circuit of the transformer with starconnected windings in phase coordinates. They have compared the suggested circuit and the traditional one. It has been found out that the deviation of the variable in symmetric modes of operation and in asymmetric ones is equal to 1-11%. It occurs because the suggested circuits take into account the ground shunts for transformers and traditional ones dont do it.

Keywords: transformer, equivalent circuit, asymmetric mode of operation.
