Glossary Of Terms


A method of connecting three phase transformer windings so that the three phase coils are connected end to end (eg: the end of one phase is connected to the beginning of the next phase). This configuration contains no neutral wire, and is intended for only phase-to-phase (aka line-to-line) loads. Schematically the three phase windings take the form of a triangle (or Greek letter delta) and the three phase wires are connected to the corners of the triangle. Some transformers are described as a “Delta-Delta” or “Delta-Wye” transformer, indicating that either the primary-and-secondary, or just the primary (respectively) has a Delta configuration. (see: Conductor; Neutral; Phase; Wye Connection; Transformer)
