I found this on a Tesla coil
users group. These guys take "pole Pigs" and reverse feed them to power
their Teslacoils. The trick is a current limiter which commen devices
are arc welders or oven elements in series with the transformer.

But still these guys are crazy IMO! Death from a slip up hewe is not an
option - it gaurenteed!

the way i can see on the photo on bottom right i can see poco pole mounted type transformer and i can see why they want to reverse feed it because they can make bigger arc than the other stuff can do and i know how much it can kick out when it ran backwards [ a quick thread jack for a sec it work the same way with old two cycle diesel engines aka detroit diesel do work teh same way and one four stroke diesel can run backward very nice is older 3208 cat engines] back to normal channels here but the whole thing that anyone want to reverse run the transformer or other device they have to understand the voltage and current is much higher than they think

and that transformer can as i did see on photo it can run much as 7.2KV !! some case much higher like 14.4 range too

merci, marc

Marc, it would be very rare to find a utility transformer that would have been connected phase to phase. The primary on that transformer is in the 8.66 kV class or 15 kV grounded wye. You guess of 7.2 kV is much more accurate and it could be as high as 7.62 kV. Outside of that range is unusual but possible. Some electric utilities work outside of that range, I know of some experimentation with a 23 kV distribution system but (I think) the idea was abandoned.

The bottom line is that this boy doesn't have a clue about how dangerous the stuff in his hands can be to him.

If he were older, I'd expect to hear the line

That is stupid I use neon sign transformers on my tesla coil.

I wonder how many times "Dude" was used during this experiment.

LOL
Anyway dudes,

Although I never tried this stunt, I was pretty much an experimental idiot when I was young (probably still am).

Did any of you others experiment much with electricity as kids?

I jambed a screwdriver into an outlet when I was very little...big spark...fuse pop...Mom screamed.

She'd always call her friend & say, "I'm going to change a fuse, call back in a few minutes to make sure I'm OK!"
