Question

. Two transformers A and B are connected in parallel to supply a load having an impedance of (2 +j 1.5m The equivalent impedances referred to the secondary windings are 0.15 +/ 0.5 Ω and 0 I +/06 Ω respectively. The open-circuit e.m.f. of A is 207 V and of B is 205 V. Calculate (i) the voltage at the load () the power supplied to the load (ii) the power output of each transformer and iv) the kVA input to each transformer [u) 189 L_ 3.8"Vr เค้า 11.5 kw (iii) 65 kW, 4.95 kw (iv) 8.7 kVA,687 kVA]
