Three identical transformers have three windings that are rated at 65.8
kV, 38.1 kV, and 13.86 kV respectively. The 13.86 kV windings are
connected in delta and energized with rated voltage at rated frequency.
The 38.1 kV windings are connected in wye and supply 9 MVA at 0
P.F. leading. The 65.8 kV windings are connected in wye and supply
15 MVA at 0.8 lagging P.F. Neglect the impedance of the transformers.
Compute the secondary line voltages (L-L) and input line current.
any ideas?
