Q3. [20 marks] A (28-X) KVA, 3000/150 V, 50 Hz, step-down transformer has the following resistance and leakage- reactance values: R₁ = (4+0.X) 2, R₂ = 0.04 02, X₁12 92, and X₂ = 0.1XQ The transformer is operating at (80-X) % of its rated load. If the power factor of the load is 0.8Y leading. determine: (i) The induced emf in the secondary winding (4 marks) (ii) The input power (4 marks) (iii) The voltage regulation (4 marks) (iv) The efficiency of the transformer (4 marks) (v) Sketch the phasor diagram (4 marks)
