Transformer Parts & types of the three-phase transformer
Core
It is made up of several sheets or metal sheets (ferromagnetic material) that are stacked next to each other, without welding, similar to the sheets of a book. The function of the core is to keep the magnetic flux confined within it and prevent it from flowing through the air, favoring core losses, and reducing efficiency.

Coils
It is the copper wire wound around the legs of the core. Depending on the number of turns (turns) around a leg, it will induce a higher voltage. It is then played with the number of laps in the primary versus those of the secondary. In a three-phase transformer, the number of turns of the primary and secondary should be the same for all phases.
Core types
The magnetic core is made up of sheets of a steel alloy (around 96%) in combination with silicon (around 04%) called “Magnetic laminations”. Transformers are of two classes: core or columnar, and armored.
- IP Tipo nucleus: The nucleus tip has three columns ubicadas paralyzed, united in its inferior and superior parts utilizing horizontal metal displays.
- Armored type: In the armored core, the windings are located on the central column. It has the advantage over the so-called column type, of reducing magnetic dispersion, it is the most common in single-phase transformers.
