A 5KVA, 240/120 V single phase transformer has the following parameters: R1 = 0.06 Q R2 = 0.015 Q X1 = 0.18 Q X2 = 0.045 Q Rc =2000 Q Xm = 400 0 Transformer secondary winding feeds an inductive load of 5KVA power factor 0.9 at 120V rated voltage. Using the simplified equivalent circuit given in the figure, find the primary voltage, primary current and apparent power factor of the transformer. What is the efficiency of the transformer? R,+R2 X,+X2 mi V =. V li = A V, V2 cose = n = % mm
