One of the usual forms or methods for connecting apparatus to a three-phase circuit, the three corners of the delta or triangle, as diagrammatically represented, being connected to the three wires of the supply circuit.

A three-phase connection where windings are connected in series with the power applied. The windings are connected in the shape of a triangle or the Greek letter delta (Δ).

Delta connection refers to a three phase connection in which the start of each phase is connected to the end of the next phase, forming the triangle-shaped Greek letter Delta. The load lines are connected to the corners of the triangle.

A method of connecting a three-phase source or load in series for a closed circuit (3-wire, plus ground).

A three-way telephone conversation.

A standard three phase connection with the ends of each phase winding connection in series to form a closed loop with each phase 120 electrical degrees from the other. In this system, three power carrying conductors are used, sometimes with a fourth safety ground wire.

Electrical circuit where the three windings of a transformer or generator are connected end to end.

Delta Connection is the name under which seven regional airlines operate short and medium haul routes for mainline carrier, Delta Air Lines.
