B Problem 1 A 30 MVA, 33/11 kV transformer with OLTC of +12.5% in steps of 2.5% in its primary side is used to supply a load of 20 MW with 0.8 power factor lagging. The transformer 38 reactance is 20% on its ratings. The feeder impedance is ZAB = 3 +j2 . a) Calculate the voltage at bus A to achieve a line voltage of 11 kV at bus B. b) Discuss the tap setting assuming that the primary voltage of the transformer is 33 kv.
