A single phase, 2000: 230 V, 50 Hz transformer is connected to an inductive load with an impedance, Zload , of 10 ∠ 30o Ω. The resistance, Rp, and inductance, Lp, on the primary side are 15 Ω and 26 mH , respectively. The core losses are represented by a resistance of 450 Ω and the magnetising reactance is 50 Ω. The secondary side resistance and inductance are 0.2 Ω and 0.1 mH. Approximate Equivalent Circuit:

Show your working clearly.
(a) Sketch the Approximate equivalent transformer for the diagram and Calculate the relevant parameters and indicate these on your sketch.
(b) Use the approximate equivalent circuit to calculate the primary current.
(c) Calculate the voltage across the load referred to the secondary.
