Figure shows an ideal three-winding transformer. The three windings 1, 2, 3 of the transformer are wound on the same core as shown. The turns ratio N: N: 3 is 4:2:1. A resistor of 10 2 is connected across winding-2. A capacitor of reactance 2.5 is connected across winding-3. Winding-1 is connected across a 400 V, ac supply. If the supply voltage phasor V = 400/0, the supply current phasor I is given by I V N N N 3 48 X =2.5 I 2 (A) (-10+j10) A (C) (10 +j10) A R=10 (B) (-10-j10) A (D) (10-j10) A Figure shows an ideal three-winding transformer.
