a) Two three-phase transformers have the following per unit secondary equivalent circuit parameters per phase, where the values have been derived from your student number using the same method as in Question 1: Transformer 1: 200 kVA R = 0.02X p. u. Transformer 2: 500 kVA R2 = 0.03Y p. u. %3D X = 0.09X p. u. X2 = 0.1Y p. u. X=2 y38 Calculate how the transformers share a load of 300 kVA at a power factor of 0.8X lagging when connected in parallel. State any assumptions which you make.
