A single-phase 400 V, 50 Hz transformer has an iron loss of 5000 W at ...
If v/f is kept constant, maximum core flux density is constant.
In the problem, (400/50) = (200/25) = 8 (416/52). v/f is kept constant. So the maximum core flux density is constant. Let it be B.

A single-phase 400 V, 50 Hz transformer has an iron loss of 5000 W at ...
Solution:
Given data:
Iron loss at rated condition (400 V, 50 Hz) = 5000 W
Iron loss at (200 V, 25 Hz) = 2000 W
Voltage at which hysteresis loss and eddy current loss to be calculated = 416 V
Frequency at which hysteresis loss and eddy current loss to be calculated = 52 Hz
Calculation of iron loss at 416 V, 52 Hz:
Iron loss is proportional to the square of voltage and frequency. Therefore,
Iron loss at (416 V, 52 Hz) = (5000/400^2)*416^2*(52/50)^2
= 7586.56 W
Calculation of hysteresis loss and eddy current loss at 416 V, 52 Hz:
Let the hysteresis loss be Ph and the eddy current loss be Pe.
Using the given data, we can write the following equations:
Ph/P e = (5000/2000)*(25/52)
Ph + Pe = 7586.56
Solving these equations, we get:
Ph = 4536.89 W
Pe = 3050.67 W
Calculation of hysteresis loss/eddy current loss ratio:
Hysteresis loss/eddy current loss ratio = Ph/Pe
= 4536.89/3050.67
= 1.4878 (approx.)
Therefore, the value of the hysteresis loss divided by the eddy current loss is 1.4423 (approx.).
