engineering recuitment PGCIL Diploma Trainee Mock Test 2024 Electrical Machines Transformer Transformer Core Losses
If the frequency of input voltage of a transformer is increased keeping the magnitude of the voltage unchanged, then
1
both hysteresis loss and eddy current loss in the core will increase.
2
hysteresis loss will increase but eddy current loss will decrease
3
hysteresis loss will decrease but eddy current loss will remain unchanged.
4
hysteresis loss will decrease but eddy current loss will increase
