Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

Symbols

Single-phase synchronous generator

This symbol identifies a synchronous generator with a single-phase output, usually two terminals or a split winding giving 120/240 V. Small standby and portable sets, and some hybrid off-grid systems, use this type because their loads are single-phase.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A single-phase generator has one output phase; a three-phase synchronous generator has three phase outputs and often a star neutral.

Symbols

Three-phase synchronous generator

A three-phase synchronous generator supplies a documented AC source associated with its mechanical prime mover and excitation system. The electrical drawing identifies terminals, neutral and generator-control connections.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / Manufacturer

A distinction that matters

The electrical generator representation is different from the complete mechanical generator package envelope.
