DESIGN OF TRANSFORMER

3.1 Introduction

Transformers are static electromagnetic devices with two or more windings and a common magnetic circuit. They are one of the primary power apparatus used in the power system network. The transformers change the AC voltage and the associated current from one level to another level, maintaining power balance between input and output side, without change in frequency. Hence, transformers perform AC energy transformation rather than energy conversion from one or more primary side circuit/s to one or more secondary side circuit/s.

The main parts of the transformer are as follows:

  • Core
  • Yoke
  • Winding

When the MVA rating is high, in addition to the above parts, transformer is equipped with

  • Bushing
  • Coolant conservator ...
