engineering recuitment UPCL AE (E&M) 2021 Mock Test Electrical Machines Transformer Transformer Core Losses
In a single-phase transformer, the total iron loss is 2500 W at nominal voltage of 440 V and frequency 50 Hz. The total iron loss is 850 W at 220 V and 25 Hz. Then, at nominal voltage and frequency, the hysteresis loss and eddy current loss respectively are
1
1600 W and 900 W
2
900 W and 1600 W
3
600 W and 250 W
4
250 W and 600 W
