Need plans for 16kv .50amp transformer, please.

Zero999:
I thought pole pigs are single/split phase in the US? Pole mounted transformers are rare in the UK and I believe both single and three phase units exist, although the latter are more common here.

Transformers that size, cost that much due to the price of the the raw materials i.e. copper and steel. Building your own won't save you any money and might cost more, since you won't be able to purchase the raw materials, as cheaply as a transformer manufacturer will. The only way to get it cheaper is to look for a scrap/second hand unit and refurbish/repair it.

T3sl4co1l:
Substitute for "pad transformer" (we have those too), or whatever is more common.  Hm, give or take the availability of 3ph over there, which may make 1ph transformers of that size actually less common?

The amount of labor spent will certainly be more than the cost alone, even if you severely discount your labor.  You're better off spending your time on something higher level -- something more fun than winding a transformer, and far more profitable -- and using the proceeds to buy into the traditional route.

Take it from a former teacher turned senior technician at a university, who did school  laser physics demos for a long time.  You'll be doing good to find an outlet in a US school capable of sourcing  500-700 watts without tripping a breaker. The 15 Amp residential or 20 Amp industrial circuit your expecting will be maximally loaded before you get there, usually has a floating ground, and will be installed with the longest possible run of the lightest guage wire possible.  Dont even expect a power outlet on the stage, even if they have theatrical lighting installed. Least bidders dont put much effort into school wiring.


Most states have a central funding board that limits spending during school construction. The limits they put on infrastructure costs are mind boggling, often with one breaker covering 3 classrooms. NEC requirements somewhat go out the window in an institutional setting. AT least in the Midwest it does.

   I was thinking the same thing.  In the US other than in industrial facilities, high current 230 VAC is only available for things like electric clothes dryers, central heating (which is built in and has no outlets) and electric ovens.  Even if the facility that OP wanted to run his TC at would let him, he'd probably be hundreds of feet from the nearest 230 VAC outlet and a large high amperage extension cord would be extremely expensive and he wouldn't be allowed to run it anywhere that the public would be present (he wouldn't be allowed to run it out of the cafeteria and down the hall and out the door and across the parking lot!) Given the scenario that the OP proposes, I would expect that the needed extension cord would costs MORE than the $800 pole pig.

Here's a link to Tesla coil safety - note the sections on UV generation and Pacemakers: https://webhome.phy.duke.edu/~rgb/Class/safety.html

If the OP is serious about the original specs, the arc is going to be pretty impressive all by itself.  The electrodes are likely going to get really hot, erode and probably deposit themselves on the inside of any containment.  I'll bet a borosilicate or even quartz tube will be needed.
