Core type transformer and shell type transformer:
The core type transformer is winding around the air between shell type.
The constructional difference of magnetic cores including two types there are two yokes and shell type transformer is having three limbs and two yokes.
CORE type transformer:
The low voltage and high voltage current are winding up the both limbs this type is only used in core type transformer.
The leakage of this process is very low.
The function of this current will convert low voltage winding to high voltage winding.
This is having less insulator.
We saw the above figure and that is called core type transformer.
SHELL type transformer:
The shell type transformer is controlled and switch in the central limb.
The above figure is shown in the transformer.
The half cycle reactant is placed in the low voltage.this is the yoke consist of central limb.
Let us saw the difference between core type and shell type transformer:
| Sr. No. | Core Type Transformer | Shell Type Transformer |
| 1) | The core consists of two yokes and two limbs. | The shell consists of three limbs and two yokes. |
| 2) | The single electric flux is exist and consis of total magnetic flux.this will composed in entire transformer. | This will opposite to the core type transformer flows through the yokes and outer limbs.it consist of two magnetic flux. |
| 3) | The High voltage current is flow around the low voltage current and it is wound by the transformer concentric. | It is placed on the central transformer of high voltage current and low voltage current. |
| 4) | The application are very high and high voltage is transformed. | Low voltage and low power. |
| 5) | The transformer winding is required for the material of conductor. | Less conductor. |
| 6) | It has less construction for iron. | The construction of core type compared to core type transformer. |
| 7) | The total flux flow through entire current circuit. | Shell type is very high compared to the core loss.this is the fact. |
| 8) | More ohm laws and more copper conductor leads to make material. | The requirement is less . |
| 9) | The shell type transformer is more less | Entire losses are less . |
| 10) | The entire efficiency is less | The overall efficiency of shell type transformer is more |
| 11) | It is more popular. | It is not popular. |
