Construction & working of Three Phase Transformer.

Construction of Three Phase Transformers

A three-phase transformer can be constructed by using common magnetic core for both primary and secondary winding. As we discussed in the case of single phase transformers, construction can be core type or shell type. So, for a bank of three phase core type transformer, three core type single phase transformers are combined. Similarly, a bank of three phase shell type transformer is get by properly combining three shell type single phase transformers. In a shell type transformer, EI laminated core surrounds the coils whereas in core type coil surrounds the core.

Types of Transformer & cooling Method.

Types of Transformer.

Transformers can be categorized in different ways, depending upon their purpose, use, construction etc.

(A) On the basis of construction, transformers can be classified into two types

(i) Core type transformer

When winding surround the core, the transformer is core form

What is Transformer?

A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Transformers are capable of either increasing or decreasing the voltage and current levels of their supply, without modifying its frequency, or the amount of Electrical Power being transferred from one winding to another via the magnetic circuit.A transformer operates on the principals of “electromagnetic induction”, in the form of mutual Induction.

Three Phase Transformers.

Three-phase Transformers are the backbone of electrical power distribution whether Delta or Star connected winding 

Thus far we have looked at the construction and operation of the single-phase, two winding voltage transformer which can be used increase or decrease its secondary voltage with respect to the primary supply voltage. But voltage transformers can also be constructed for connection to not only one single phase, but for two-phases, three-phases, six-phases and even elaborate combinations up to 24-phases for some DC rectification transformers.
