ECN Forum Forums Technical Discussion Electrical Theory and Applications Discussion- Zig-Zag Grounding Transformers

This thread can be used to discuss the drawings posted in the Technical Reference area intitled:

Zig-Zag Grounding Transformers

Feel free to ask question(s), make comments or discuss this topic in detail.

If you would like these or other drawings from the Technical Reference area sent to you as Raster Images [.gif, .jpg, .bmp], as Metafiles [.wmf], or as AutoCAD R14 files [.dwg], contact me via e-mail or post a message in this thread.
Please specify which type of file format you would like, along with the name of drawing / text .
The images / text will be sent via ".ZIP" compressed file, using PKZIP 2.60 for Windows / DOS. If needed, I can send as Self Extracting Zip files, which work fine in Windows 95, 98, Me, NT4 and 2000 Enviroments, but have not worked correctly under Windows XP as of 08.01.2002.

Let me know if these drawings are helpful or if they suck!

a noodle is created, so the definition of SDS comes to mind, and the 'no direct electrical connection' angle commonly debated.

It may be worth noting that the voltage across each inividual coil in a non-fault condition is 0.5774 of the phase-to-neutral voltage, so, for 480Y/277V, each coil operates at 160 volts.

Scott,
Those are very good diagrams, even an idiot like me can see how the Zig-Zag connection works!.
