what is Iron loss in a Transformer and how can it be reduced
Answers
Answer:
Iron losses take place in cores of electromagnetic devices.
Iron losses in transformer are of two types:
Hysteresis loss
Eddy current loss
The hysteresis is caused by continuous magnetization & demagnetization of core.
This causes some loss, which is determined by plotting graph of B(magnetic flux density) Vs H(magnetic field strength); which gives curve called as hysteresis loop. The hysteresis loss is noting but area of this hysteresis loop.
The hysteresis loss can be reduced by implementing material having smallest area of hysteresis loop.
So generally silicon steel is used, which is having least hysteresis loop area.
The eddy current loss is caused due to induction of emf in core which causes flow of circulating currents in core. These circulating currents are called as eddy currents.
The heat loss taking place due to these circulating currents is called as eddy current loss.
This can be reduced by manufacturing core in form of stack of lamination.
Total constant losses in transformer are summation of hysteresis & eddy current losses.
I hope you have understood the concept.
Explanation:
Answer:
To align the magnetic domains of ferromagnetic material due to alternating Flux there is loss of energy is called as hysteresis loss and circulating current on the core material is called as eddy current loss.
These two combine to form constant losses also known as Iron of the transformer
