An equivalent circuit is described for the three-winding transformer which is similar in form to the classical equivalent T of the two-winding transformer. As in the equivalent T, the performance of the circuit shown can be visualized and the elements of the circuit can usually be related to ...
Determination of exact equivalent circuits of Transformer and Induction Motor from on-line measurements In this article, the six parameters of the exact equivalent circuit of the transformer and the induction motor are determined. For the transformer, the equivalent circuit parameters are determined by ...
The method gives a flexibility to choose a range of practically observed reactance to resistance ratio (X/R) of transformer and also allows to use a range of dc current limiting resistances used in the high voltage power supply test circuit. The non-linearity of the system is also considered...
