Two single-phase transformers A and B are operating in parallel with the different pu impedance (Za > Zb) and identical x/r ratios (Xa = Xb). Then
Za/Zb = Sb/Sa
Za/Zb = Sa/Sb
Za/Zb = 1
Za/Zb = (Sb/Sa)²
Za/Zb = Sb/Sa
Quick Summary: Practice and solve "Two single-phase transformers A and B are operating in parallel with the different pu impedance (Za ..." for Electrical - Machine. The correct answer is Option A: Za/Zb = Sb/Sa. Detailed step-by-step solution, conceptual clarity, and formulas on Examoogle.
