Does SquareD/Schneider Electric offer any Zig Zag connected Transformer windings?

Issue:
Zig Zag Transformer secondary windings

Product Line:
LV Transformers

Environment:
Applies to LV Transformer products by SquareD/Schneider Electric

Cause:
Zig Zag winding configurations have specific electrical applications


Resolution:

Yes, SquareD/Schneider Electric can build any standard NEMA winding configuration, of which a Zig Zag is. The Zig Zag is typically only useful in certain applications involving variable frequency drives when used in conjunctiion with other drives fed by standard delta-wye Drive Isolation Transformers. However, there has been a recent push by small Transformer vendors to attempt to give the Zig Zag some validity for feeding standard office type line-to-neutral non-linear loads. Those claims lack validity.  Zig Zag windings are also used in Harmonic Mitigating Transformers (HMT's).  For more information, contact Product Marketing/Support.
