What do the coil configurations look like for delta-connected and wye-connected three-phase generators?

• A. A triangle and a Y
• B. A hexagon and a line
• C. A circle and a cross
• D. A square and a T

Answer: (A)

Three-phase generator windings can be connected in two common ways: delta and wye. In a delta connection, the windings are connected end-to-end to form a closed loop, which visually appears as a triangle with the line terminals at the triangle’s corners. In a wye connection, one end of each winding is joined at a common neutral point, and the other ends extend outward to the three line terminals, forming a Y (star) shape. So the coil configurations look like a triangle for delta and a Y for wye.
