transformer banks

Symmetrical component method 1 is almost essential for the analysis of unbalance conditions in which the impedances of rotating machines play an important role. most problems in which the main regulating factors are the impedances of transformer banks can; instead; satisfactorily resolved by combining the single transformer theory with the relationships between voltages and currents in triphasic circuits. next; and as a review; the simplified theory of the transformer and the equations of the triphasic circuits are summarized
