# ANSI/IEEE reactor symbol

Canonical URL: https://eloragrid.ai/symbols/ansi-reactor
Publisher: Elora Grid
Updated: 2026-10-14
Lookup label: L
Drawing use: SLD, Schematic
Reference families: IEEE / ANSI, Manufacturer

## Symbol convention

Convention: IEEE / ANSI
Form: Autodesk IEEE-oriented Reactors functional form
Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.
Related representation: [Reactor](https://eloragrid.ai/symbols/reactor)

IEEE-oriented graphical reference for reactor, with public vendor evidence and drawing-reading notes.

## What it represents

The reactor form identifies an inductive component in the documented power circuit. Series or shunt connection establishes its placement, while the device schedule explains whether its intended duty concerns impedance, filtering or another application.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.

## How to read it

- Trace the external connection before interpreting the inductive outline.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.

## Information to show or reference

- State circuit duty
- Record current/impedance data
- Reference equipment model

## Important distinction

A reactor's winding is not an additional transformer secondary unless magnetic coupling is explicitly part of the device.
