You can easily understand the following figure.
Transformer core is made of laminated for what purpose.
For efficient flux linking between these windings one low reluctance magnetic path common to all windings should be provided in the 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.
The transformer can be mounted on a utility pole if so it is called a pole mounted distribution transformers.
Purpose of transformer core.
Instead in a number of properly sized shaped and laminated sheets of crgo silicon steel are assembled together to form the transformer core.
Core laminations consist of thin metal strips of insulated metal.
A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites.
The performance of a transformer mainly depends upon the flux linkages between these windings.
The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one.
What is the construction of the transformer.
In all types of transformer construction the central iron core is constructed from of a highly permeable material made from thin silicon steel laminations.
The transformer is made of laminated iron core and steel strips.
The purpose of providing an iron core in a transformer is to.
These thin laminations are assembled together to provide the required magnetic path with the minimum of magnetic losses.
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.
Such a design tends to exhibit more losses but is very economical to manufacture.
Distribution transformer also has a different type of classification based on the location it is used.
Provide support to windings.
Decrease the reluctance of the magnetic path.
It is made using laminated steel plates mostly constructed in c shape as a core material.
This arrangement increases the overall resistance of the core.
Transformer core laminations the core is not generally made of the solid transformer core material that is solid crgo silicon steel.
