Three-phase transformers work by utilizing three sets of primary and secondary windings, each corresponding to one phase of the electrical system. They can be configured in various ways, such as delta or wye (star) connections. This design allows for efficient power distribution and transformation, balancing loads across the three phases. When alternating current flows through the primary windings, it generates a magnetic field that induces voltage in the secondary windings, enabling the transfer of electrical energy.
