Question

For a conceptual single-phase phase-shifting transformer, the primary voltage leads the secondary voltage by 308. A load connected to the secondary winding absorbs 110 kVA at an 0.8 power factor leading and at a voltage E2 = 277 (angle of 0 degrees) volts. Determine (a) the primary voltage, (b) primary and secondary currents, (c) load impedance referred to the primary winding, and (d) complex power supplied to the primary winding.

Step 1

Since the secondary voltage E2 has an angle of 0 degrees, the primary voltage E1 will have an angle of 308 degrees. The magnitude of the primary voltage can be found using the transformer turns ratio, which is equal to the voltage ratio: E1 / E2 = N1 / N2 Since Show more…
