About Three Phase Transformer And EI Lamination

Three phase transformers are more economical for supplying large loads and large power distribution. Even though most of the utilization equipments are connected by the single phase transformers, these are not preferred for large power distribution in the aspect of economy. The three phase power is used in almost all fields of electrical power system such as power generation, transmission and distribution sectors, also all the industrial sectors are supplied or connected with three phase system. Therefore, to step-up (or increase) or step-down (or decrease) the voltages in the three phase systems, three phase transformers are used. As compared with the single phase transformer, there are numerous advantages with 3 phase transformer such as smaller and lighter to construct for the same power handling capacity, better operating characteristics, etc.

In order to achieve the ideal working efficiency and high permeability of the transformer, cold-rolled non-oriented or oriented silicon steel sheet is usually used as the core.
