Try the following Problems Problem I The equivalent circuit of a 50 kVA 2400/240 V transformer is shown below. The transformer is connected to 0.8 pf lagging load at rated voltage at secondary terminals at rated kVA. The transformer efficiency and voltage regulation are found to be 97% and 2% respectively. It was found that copper loss 600 W. The impedance seen at primary terminals is 110 40° 2. Take Rel = 1.21 2 and R2=90.41 2. Find Xm2 and Xel Re1 Xel E E Xm2 Rc2
