  • Q: How do three-phase transformer connections work?

    A: Three-phase transformers consist of a three-legged iron assembly with two windings on each leg, a primary winding connecting to the power supply and a secondary winding connecting to the load circuit. Changing current in the primary creates flux, which creates voltage in the secondary winding. Transformers work according to the principle of mutual induction; electric current produces flux, a magnetic field, and a change in flux within a coil of wire induces a voltage across the ends of the wire.
