Definitions:

Wye-Connected

A configuration where three elements (like resistors, inductors, or capacitors) in a circuit are connected at a single common point or node, forming a Y shape.

Secondary Line Voltage

The voltage seen across the secondary winding of a transformer or at the output of a power supply, typically lower than the primary voltage.

Turns Ratio

The ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer, affecting its voltage transformation.

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.
