Yz5

IEEE / ANSI

ANSI/IEEE Yz5 transformer connection reference form

This reference locates yz5 transformer connection reference in Autodesk's IEEE-oriented 3 phase transformers family. Yz5 combines an HV-side star winding designation with an LV-side zigzag designation and clock group 5. The letters describe connection topology; the final number identifies the phase relationship recorded with the transformer connection diagram. It is different from the voltage ratio or the number of terminals. The public library uses HXF1T28 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

3 Phase Yz5. Autodesk IEEE Symbol Preview: 3 Phase Transformers, block HXF1T28. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

The clock-group suffix is different from a voltage ratio, power rating or physical terminal number.
