Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

CT 2SEC

IEEE / ANSI

ANSI/IEEE current transformer with two secondaries symbol

This CT form identifies two documented secondary windings on a common magnetic circuit. Separate secondary connection paths must remain visible so a reader can follow their respective meters or relays without assuming independent cores.

Drawing use: SLD / Schematic
Application: Metering & protection
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Current Transformers 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.

A distinction that matters

Two secondary windings on a common magnetic circuit differ from two independently specified protection cores.

Current transformer with two secondaries

A CT with two secondary windings supplies two documented secondary circuits. A common magnetic circuit must not be mistaken for independent protection cores.

Drawing use: SLD / Schematic
Application: Metering & protection
Reference family: IEC / Manufacturer

A distinction that matters

Two secondaries on a common magnetic circuit are different from separate CT cores.
