A  100 kVA,3-phase, 50 Hz, 3300/400 V transformer is ∆-connected on the h.v. side and Y-connected on the l.v. side. The resistance of the h.v. winding is 3.5Ω per phase and that of l.v. winding 0.02 Ω per phase. The total full-load losses of the transformer operating at full-load efficiency of 95.8% and p.f. 0.8 (lag) are
  • a)
    3500 W
  • b)
    5200 W
  • c)
    4800 W
  • d)
    2400 W
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
A 100 kVA,3-phase, 50 Hz, 3300/400 V transformer is -connected on the ...
F.L. output =100×0.8=80 kW;
F.L. input =80/0.958=83.5 kW
∴ Total F.L. losses
= 83.5 - 80 = 3.5 kW
= 3500 W
