Put another cross piece in between each one you already have so the buss will have a place to be attached at both ends.Then drop a wire down to your bushings from the buss .I think you found a good source for pole transformers.


David, does it look correct now? I think I understood what you stated. Thanks.

Little update.



The wires were made with 22 gauge stranded. Crazy glued it to side of nail head on insulator assembly.





Stringing up top insulators.

Ces,

The wire don't go in that tube.It goes to those things on top .They're insulators and should be painted brown.Put 3 more insulators for each group on the back side of the lowest cross piece.What your working towards is getting the wire OUT of the station so you come out of the XFMR and into the breaker out of the breaker into the OCR's out of the OCR's and up to the poles.Remember we said think in 3's

This is a side view of what you should have .Now remember you have to do this 3 times for each group.That's why I said you need the extra cross pieces

David


You didn't goof .He just doesn't have his right either.If you look at my drawing under where it says poles? you'll see the correct way it should look in that area

High voltage wires go in the top and OUT the top so people won't walk into them

Paint the top insulators brown on the little XFMR's like you did the K-Line ones.

and put your wire to the top of them.Print my drawing off so you can lay it beside your project then it'll make more sense.Remember think in 3's

each bushing(Insulator) off the XFMR has to have a set up like what I drew
Remember that fourth bushing is a ground????

So far you have the XFMR and the OCR you still need the breaker in between them.
Keep going and I'll draw you another one if you get stumped

Ron,

We used 138KV,345KV,500KV and 765KV but Cesar's stuff is much smaller and to keep confusion to a minimum I drew it as simply as possible

No, no, not that Electric company, please!  I heard that theme song so many times when my kids were growing up . . . I don't want it in my head again.

 

And for the record, these transformers aren't the type in the movies either (although it would be kinda neat to make a transformer that transformed into a Transformer, now that you think about it).

This picture is from Norm Charbonneau's website.  Norm did a fantastic job on this pole mounted three phase transformer bank.  If you look closely it appears to be a "Y" -- "Y" connection.  Top terminals on the cans are high voltage.  Side terminals are low voltage to the conduit leading to the building. Missing would be (3) High voltage disconnects, most likely mounted on the middle cross arm, and connections to the ground wire, stapled to the pole.  At one time you would see a lot of power supplies like this in either 4KV or 8KV, here in Western PA.  There are a few communities in Western PA that still use 4KV distribution systems.   A very good example of how pole mounted transformers should be connected. IMO, Mike
