# ANSI/IEEE current-measuring shunt symbol

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

## Symbol convention

Convention: IEEE / ANSI
Form: Autodesk IEEE-oriented Resistive Components 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: [Current-measuring shunt](https://eloragrid.ai/symbols/current-measuring-shunt)

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

## What it represents

The shunt form identifies a resistive current path used to derive a voltage measurement. Power-current terminals and voltage-sense leads must be distinguished where the actual device provides separate sensing connections.
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

- Follow the sense circuit without confusing it with the full-current path.
- 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 current/voltage-drop rating
- Show sense terminals
- Reference polarity/scaling

## Important distinction

A shunt produces a measured voltage drop; a CT provides an instrument-transformer secondary current.
