1- A 1-phase transformer has 400 primary and 1000 secondary turns. The net cross- sectional area of the core is 60 cm². If the primary winding be connected to a 50 Hz supply at 500V. calculate a/ the peak value of the flux density in the core, and b/ the voltage induced in the secondary winding. [a/ 0.94 wb/m²; b/ 1250V]

Three-Phase Transformers

Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.

Transformer

Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
