In devices like transformers the core is made up of laminations of iron.
Transformer core is laminated to reduce which loss.
A transformer core is laminated to.
In other words low reluctance should be retained.
The yoke sections of transformers using hot rolled laminations is made 15 per cent greater than that of the core so as to to increase the size of the transformers to reduce the copper loss to reduce the iron loss in yoke and magnetizing current.
Transformer multiple choice questions and answers.
And alsobe reducing the thickness of the stampings.
A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses.
Transformer iron lossis the combination of eddy current loss and hysterisis loss.
In order to reduce the eddy current loss the resistance of the core should be increased.
Reduce eddy current loss.
Eddy current can be reduced by using laminated cores.
Reduce all above losses.
A further improvement is a core made of amorphous metal alloys.
Asked mar 24 2018 in physics by paayal 147k points the core of any transformer is laminated so as to a reduce the energy loss due to eddy currents b make it light weight.
If you employ inferior grade of laminated steel with poor magnetic properties then only eddy loss will be controlled but not hysteresis loss.
