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

Three-phase induction generator

An induction generator is an asynchronous machine driven slightly faster than synchronous speed by a turbine or engine. It exports active power but needs reactive power from the network or from capacitors to establish its magnetic field, so it cannot normally hold voltage and frequency on its own.

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

A distinction that matters

An induction generator draws its magnetising current from the network; a synchronous generator has its own field and can regulate voltage.

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.
