Understand the difference.

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

CT TAP

IEEE / ANSI

ANSI/IEEE tapped-secondary current transformer symbol

The tapped-secondary CT form marks alternative documented secondary connection points. The connected tap pair determines the operating transformation ratio; unused terminals remain subject to the actual transformer instructions rather than a generic drawing rule.

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

A winding tap selects a documented connection ratio; it is not another independent measurement core.

Symbols

Tapped-secondary current transformer

A tapped CT secondary provides alternative documented transformation ratios through different terminal combinations. The schematic must identify the selected tap and the treatment of unused terminals.

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

A distinction that matters

A tapped winding selects a ratio; it does not create two independently loaded measurement windings.
