how does a 3 phase transformer work ppt?

A 3-phase transformer operates by using three sets of windings, each corresponding to one phase of the electrical supply. It transforms voltage levels between high and low voltages while maintaining the phase relationship. The primary windings receive the input voltage, inducing a magnetic field in the core, which then induces voltage in the secondary windings. This design allows for efficient power distribution and is commonly used in industrial applications for its ability to handle large loads.
