Exercise 4.4 ▸ A 2.4 KVA, 2400/240 V 50 Hz step down transformer has the following parameters ▶ R₁= 1.552, X₁ = 2.502, R₂ = 0.0202, X₂ -0.030, Rc1 = 6k, Xm1 = 8kQ ▸ 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.
