A 600-kVA, single-phase transformer with 0.012 pu resistance and 0.06 pu reactance is connected in parallel with a 300-kVA transformer with 0.014 pu resistance and 0.045 pu reactance to share a load of 800 kVA at 0.8 pf lagging. Find how they share the load (a) when both the secondary voltages are 440 V.

• A. when both the secondary voltages are 440 V.a) S1= 377+j305.2
• B. S2= 377-j305.2
• C. S1= 264+ j171.6
• D. S1= 377-j305.2
