Zig-Zag Transfomers
Zig-Zag Transfomers
(OP)
I'm familiar with the general purpose and use of these type transformers, but would be interested if anyone knows of any resource that provides a reasonably rigorous technical discussion of how the transformer reacts to various unbalanced conditions.






RE: Zig-Zag Transfomers
Zig-zag transformers are rarely purchased any longer (in the US) so technical info will be hard to come by.
If you have access to Edith Clarke's books, those would be helpful as well. But these are long out of print.
Good luck...
RE: Zig-Zag Transfomers
Thanks. I have both the Westinghouse and Clarke's books and have referred to them. They both briefly discuss the zig-zag transformer, but I was hoping for something more in depth.
Thanks again.

Other zig-zag manufacturers (South Africa) are:

(Products, Power & Distribution Transformers)
I think ABB South Africa also build zig-zag transformers.
Zig-zag transformers are also called earthing transformers, NECs or Neutral Earthing Compensators/Couplers

But they are becoming pretty rare.
