A single-phase two-winding transformer is rated 20 kVA, 3300/240 V, 50 Hz. A source connected to the 3300 V winding supplies an impedance load connected to the 240 V winding. The load absorbs 15 kVA at 0.8 p.f. (lagging) when the load voltage is 228 V. Assuming primary voltage (4)
(b) The load impedance (5)
(c) The load impedance referred to the 3300 V winding (2)
(d) The real and reactive power supplied to the 3300 V winding (4)
