Question

in transformer the half load copper loss is 600 watts. At full load copper loss, the copper load will be (how to calculate half load to full load) ?​

Answer 1

Answer:

The copper losses of transformer at X times the full load is proportional to X^2 times the losses at full load. Hence at half the full load, the copper losses will be (0.5)^2 * 1600 = 400 Watts
