In devices like transformers the core is made up of laminations of iron.
Transformer core is laminated to reduce which loss.
Transformer iron lossis the combination of eddy current loss and hysterisis loss.
A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses.
If you employ inferior grade of laminated steel with poor magnetic properties then only eddy loss will be controlled but not hysteresis loss.
A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses.
A transformer core built with crgo si steel laminations thereby reduces both losses.
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.
A transformer core is laminated to.
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.
Eddy current can be reduced by using laminated cores.
In order to reduce the eddy current loss the resistance of the core should be increased.
In other words low reluctance should be retained.
Reduce all above losses.
