Wye-Delta Transformer

A transformer configuration used to shift between high and low voltages in a three-phase electrical system, involving a star (Wye) connection and a delta connection.

Wye

A configuration in electrical engineering where three phase circuits are connected at a single point, forming a 'Y' shape, allowing for both three-phase and single-phase connections.

Delta

A method of connecting three electrical components in a triangular configuration, allowing for the completion of a circuit without a neutral path.

Open Delta

A connection method for three-phase transformers where only two transformers are used, providing a way to supply three-phase power with reduced capacity.
