Yy6

IEEE / ANSI

ANSI/IEEE Yy6 transformer connection reference form

This reference locates yy6 transformer connection reference in Autodesk's IEEE-oriented 3 phase transformers family. Yy6 combines an HV-side star winding designation with an LV-side star designation and clock group 6. 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 HXF1T24 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

3 Phase Yy6. Autodesk IEEE Symbol Preview: 3 Phase Transformers, block HXF1T24. 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.
