A 2.4 kVA, 2400/240 V 50 Hz step down transformer has the following parameters R1= 1.5Ω, X1= 2.5Ω, R2 = 0.02Ω, X2 =0.03Ω, Rc1 = 6kΩ, Xm1 = 8kΩ 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 , the voltage regulation and sketch its phasor diagram.
