A 2.4 KVA, 2400/240 V 50 Hz step down transformer has the following parameters R₁ = 1.52, X₁ = 2.52, R2 = 0.022, X₂ =0.032, Rc1 = 6k, Xm1 8ΚΩ = It is operating at 80% of its rated load at 0.8 power factor lagging. Using the approximate equivalent circuit of the transformer referred to the secondary side, determine its efficiency (61.4%), the voltage regulation (0.205%) and sketch its phasor diagram.
