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.

G DC CMP

IEEE / ANSI

ANSI/IEEE compound-excited DC generator symbol

A compound-excited DC generator combines a shunt field across the armature with a series field carrying load current. Depending on whether the series field aids or opposes the shunt field, terminal voltage can stay nearly flat, rise or fall with load. Such machines survive in legacy battery charging, traction and test installations.

Drawing use: Schematic
Application: Microgrid systems
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented DC Generator with Compound Excitation functional form. Autodesk publishes this block under its IEEE Symbol Preview for generators. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A compound generator has both series and shunt fields; a plain DC generator symbol does not specify the field arrangement.

G DC COMP

Symbols

Compound-excited DC generator

A compound-excited DC generator uses documented series and shunt excitation components. The drawing must identify their connections rather than relying on a generic generator circle.

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

A distinction that matters

Compound excitation combines field arrangements; it is different from a permanent-magnet generator.
