Multiple Choice

The three coils in a generator are connected in a ______ or ______ configuration.

Three-phase generator windings are typically arranged in two standard ways to create the three-phase output: Delta or Wye. In a Delta connection, the ends of the three windings are tied together in a loop, so each line terminal connects to a corner of that loop. This means the line voltage equals the winding’s phase voltage and the line current is higher for a given winding current. In a Wye (also called Star) connection, one end of each winding is tied to a common neutral point, and the other ends form the three line terminals. This arrangement gives a line voltage that is the phase voltage multiplied by sqrt(3) and provides a neutral for single-phase loads. So the standard pair of configurations is Delta or Wye. The term Star is simply another name for Wye, and the question uses the standard terminology to emphasize the two common configurations. The other options aren’t used to describe the primary three-phase winding arrangement: Open or Closed isn’t a standard three-phase configuration, and Parallel or Series refers to how windings within a phase are connected, not the overall phase configuration.
