ANSI/IEEE Delta-star transformer form

This reference locates delta-star transformer in Autodesk's IEEE-oriented 3 phase transformers family. A delta-star transformer provides a delta-connected winding and a star-connected winding. Where the star point is brought out, its neutral and earthing arrangement are separate drawing requirements. The public library uses HXF1T14 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

Form evidence

3 Phase Delta/Star. Autodesk IEEE Symbol Preview: 3 Phase Transformers, block HXF1T14. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

A star winding can exist without an accessible or earthed neutral terminal.
