Question 41
EEMCQ2 marksNeeds review
A three-phase two-winding transformer has a voltage transformation ratio
, where
is the primary side voltage in p.u., and
is the secondary side voltage in p.u.
and
represent the currents injected into the primary and secondary sides of the transformer, respectively. The admittance corresponding to the leakage impedance of the transformer referred to the secondary is
p.u. Neglect the magnetizing branch. 
The Y bus representation of this transformer is:
