A 150-kVA, 2400/240-V single-phase transformer has the following parameters: R1 = 0.2 ; X1 = 0.45 ;R2 = 0.02; X2 = 0.0045 ;Rc = 1000 ; Xm = 1500. The transformer is connected to a 150kVA load with 0.8 power factor lagging.

(a) Determine the equivalent circuit referred to the high-voltage side

(b) Find the primary voltage and voltage regulation when the transformer is operating at full load, 0.8 power factor lagging and 240V

(c) Find the primary voltage and voltage regulation when the transformer is operating at full load, 0.8 power factor leading

(d) Use the trans program in Matlab to verify your results and plot the efficiency curve (transformer performance)
