Laminated Iron Core Transformer

Transformers are basically two coils of wire wrapped around a core of iron.
Laminated iron core transformer. The reason we laminate the iron cores in transformers is because we want to limit what are called eddy currents. The layers of insulation serve as a barrier to eddy currents so eddy currents can only flow in narrow loops within the thickness of each single lamination. Why iron core is thin laminated in transformer the iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer. 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 good voltage regulation of a transformer means a.
Transformers used for the distribution and control of electrical energy consist of a primary and secondary copper wound coil carrying a magnetizing current surrounding an iron core which is used for the transferring of power from the primary to the secondary coil. Output voltage fluctuation from no load. Iron core is the main part of magnetic circuit in transformer. The iron core is made of silicon steel what is a kind of magnetic substance with strong magnetic conductivity that produce great magnetic induction.
It usually made of hot rolled or cold rolled silicon steel sheets with high silicon and insulating paint on the surface. Eddy current is induced in core and circulates normal to the width of the core causing heat. Instead of having one big solid iron core as the magnetic core material of the transformer or coil the magnetic path is split up into many thin pressed steel shapes called laminations. Laminated means made up of insulated layers of iron glued together rather than being in a single solid lump.
The eddy currents cause energy to be lost from the transformer as they heat up the core meaning that electrical energy is being wasted as unwanted heat energy.
