Definitions:

Delta-Wye Transformer

A type of electrical transformer that can convert between delta and wye (star) configurations, facilitating the transformation of voltage levels and phase shift adjustments in power systems.

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.
