ANSI/IEEE Star-zigzag transformer form

This reference locates star-zigzag transformer in Autodesk's IEEE-oriented 3 phase transformers family. A star-zigzag transformer combines a star-connected winding set with a zigzag-connected set. Its winding arrangement and neutral duties require the manufacturer's complete connection designation. The public library uses HXF1T12 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

3 Phase Star/Zigzag. Autodesk IEEE Symbol Preview: 3 Phase Transformers, block HXF1T12. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

A zigzag connection is not another spelling of a simple star winding.
