What is a three phase transformer?

A three phase transformer is a three-legged iron core. Each leg has a respective primary and secondary winding. Most power is dispersed in the form of three-phase AC. Basically the power company generators produce electricity by rotating 3 coils or windings through a magnetic field within the generator.

What are the uses of three phase transformer?
Three phase transformers are designed to supply electric power to three-phase systems. These electrical devices have three circuit conductors and may or may not have a neutral wire. Three phase power is used by electric power distribution grids and to power large motors and other large loads.
