Understand the difference.

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

TX SCREEN

IEEE / ANSI

ANSI/IEEE electrostatically screened transformer symbol

The screened-transformer form identifies a separate electrostatic-screen feature associated with the windings. Follow the screen connection as its own conductor, with the manufacturer's designated earth or bonding arrangement.

Form evidence

Autodesk IEEE-oriented 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

An interwinding screen differs from the transformer's magnetic core and from a protective-earth symbol beside its enclosure.

TX SCREEN

Symbols

Electrostatically screened transformer

A screened transformer includes a documented screen between windings. The drawing must show the screen connection separately from the magnetic coupling and winding terminals.

A distinction that matters

A screen connection is not an extra power winding or a guarantee of every isolation requirement.
