Look at the center tap of the transformer, though! That ALSO connects to ground, AND it's neutral. 0v at the center tap. There is no "fourth neutral wire". Neutral is simply connected to ground.I don't think SWER is used in urban areas, from what I can gather. And if you look at my photos, there is no evidence what-so-ever of a 4th wire neutral returning to a Y transformer. The primary conductor entering the polepig obviously connects to 1 of the 3 available high voltage phases from the power company. The primary conductor leaving the polepig doesn't appear to connect to any neutral wire at all. It runs down the pole, disappears into the ground, and functions merely as a safety "ground" wire.
Christ almighty! That's where I got so screwed up! I've never heard the term "multi-grounded neutral" before.
Depending on where you are, you might not see a special wire for the "MGN". If the transformer and load are grounded, and the power company has their neutral grounded, the earth will act as the MGN line. Anything that is connected to neutral or to ground are all connected together in one way or another, whether it be through a separate wire or through the ground itself.Christ almighty! That's where I got so screwed up! I've never heard the term "multi-grounded neutral" before.
Thanks for the link to this image, t_n_k. A good picture really is worth a thousand words.
I didn't notice the MGN on the pole that I photographed, but tomorrow I'm going
to go back outside and re-survey my neighborhood's poles again and locate the MGN.
I'm also going to look for the static wire cuz I don't remember seeing it, either.
