  • Three Phase Transformers

    A 3phase wye/delta transformeris rated 225kV/24kV, 400MVA and has a series reactance of 13.3ohms as referred to its high voltage side. The transformer is supplying a load of 325MVA at 0.9 pf lagging at a voltage of 24kV(line to line)on its low voltage side. It is supplied from a feeder whose impedances are (0.15+j1.5)ohms connected to its high voltage terminals. For these conditions calculatea> The...
