ANSI/IEEE Single-phase AC source form
IEEE-library form of single-phase ac source: a single-phase AC source identifies a documented source boundary in a schematic or SLD.
In plain English
What does ANSI/IEEE Single-phase AC source form mean?
This reference locates single-phase ac source in Autodesk's IEEE-oriented miscellaneous family. A single-phase AC source identifies a documented source boundary in a schematic or single-line diagram. The source label and supply data explain what provides the circuit's voltage and frequency. The public library uses HPW1_1PH for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Use the surrounding circuit labels and the project legend to identify the intended operating condition and connection. Carry the same device reference into the schedule or equipment document so the symbol can be reconciled with its real terminals, function and operating limits.
What the drawings help you do
Determine whether the source is a utility connection, transformer winding or auxiliary source. A source-boundary symbol is not a product-specific generator or transformer diagram. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

How to read it
- Determine whether the source is a utility connection, transformer winding or auxiliary source.
- 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
- Name source origin
- State voltage/frequency
- Show conductor and neutral arrangement
A distinction that matters
A source-boundary symbol is not a product-specific generator or transformer diagram.
