Example 1.6. An ideal transformer has three windings: 100 turns on primary winding P, 160 turns on secondary winding S and 60 turns on tertiary winding T, Fig. 1.13 (a). Winding S feeds 10 A to a resistive load whereas a pure-capacitance load across winding T takes 20 A. (a) Calculate the current in the primary winding and its pf in case transformer magnetizing current is neglected. (b) With the polarity markings on P as shown, mark the polarities on windings S and T also, na
