The leakage reactance of a three-phase transformer, when referred to its low voltage side, is X₁ = 2.0 2/phase. The rated voltages of the transformer high and low voltage windings are 132 kV (rms ph-ph) and 33 kV (rms ph-ph) respectively and the transformer MVA rating is 80 MVA. Calculate the leakage reactance of the transformer in per-unit on its rated voltages and MVA. [2 marks] A three phase load is consuming real and reactive power of P+jQ=0.80+ j0.16 pu on a three phase MVA base of 200 MVA. The load bus voltage phasor is = 0.95/0° pu on a base voltage of 132 kV (rms, ph-ph). Calculate the per-phase current magnitude, in Amperes, supplied to the load.
