More transformer platform porn

[electrofelon]

I've been taking pictures of these whenever I see them. Unfortunately nothing real ridiculous, although that one appears to be real low because its down and embankment a bit. All autos probably?

 

[GoldDigger]

Number 1 looks like an open delta, while number four, with mismatched sizes might, maybe, be a high leg? Or just what they had sitting around?
I can't really see the secondary conductors.

Thought I was crazy but I know exactly where #3 is. Not sure if you were looking for transformer platforms or a good time :lol:

 

[mbrooke]

1 and 2 are 32 step voltage regulators, while 3 and 5 appear to be 2 winding isolation with a secondary 5kv and below. #4 looks like a step down with a delta secondary, but the image is not 100% telling.

I am guessing #1 is also open delta since all the phases are tapped but only 2 reg cans, in addition to what looks like no primary neutral on the pole to the left.

Anyone care to take a guess on this “accessory”

Paint roller? :lol::?:lol:

Lol thats right, you are from around there. Yes I was in search of a good time - Schenectady is a transformer platform watchers paradise!

Do you also enjoy watching already dried paint?

1 & 2 are automatic voltage regs. 3, 4, & 5 are most likley wye/delta banks. It looks like #4 is hooked up wye/delta; probably feeding an old 2400 or 4800 volt system. I find it odd that #1 only has voltage correction on 2 phases, if you look closely you can see (or not see, hehe) no insulator on the center phase.

You people are sick... some of those trannies look to be under 18 years old.

Trust me, its the tip of the iceburg. At least for me anyway :lol: I photograph street lights just because I like how they look, and all the different models out there.

Yup, open delta correction. Common on pure 3 wire circuits because it requires only two regs instead of 3.


See pages 4 and 5 for the various connection types:

Interesting. That's something new, thank you for the documentation. When we build a regulator bank we never hook them up in open delta, its either 3 for 3 phase or 1 for single.

Interesting to see that, none of the major poco's in my area use the platform construction standard.

Id guess because your system is 4 wire wye, which mandates 3 regs if you want all 3 phases to have the correct voltage.

Most of our network is 4w wye. We have a lot of delta too. My coverage area actually more delta than wye, very rural and long runs. Still; using 2 regs in an open delta is something I've never done.

Never say never, it might be tomorrow where an open delta is required

 

[electrofelon]

What are those things that look like guages?

 

[truck41trouble]

That indicates the tap position. At least on the ones ive worked on.
