A three-phase synchronous generator supplies a documented AC source associated with its mechanical prime mover and excitation system.

## What it represents

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.

## How to read it

- Locate the voltage/current measurement points used by the generator controls.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- State output and winding ratings
- Show neutral arrangement
- Reference excitation and protection

## Important distinction

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

## Facts

- Drawing role: Generating source
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HPW1G7, VPW1G7 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
