An active-power indicator displays real power derived from its specified measurement inputs.

## What it represents

An active-power indicator displays real power derived from its specified measurement inputs. On an SLD it identifies the monitored feeder or source; the schematic supplies phase and ratio details.

## How to read it

- Identify the power-flow sign reference at the measurement location.
- 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 measured feeder
- Show current/voltage inputs
- State import/export convention

## Important distinction

Active-power indication differs from reverse-power protection, even when both use the same measured quantity.

## Facts

- Drawing role: Indicated quantity
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HIN1P19, VIN1P19 (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.
