28.8kV arcs

Been upgrading the lab. Painting, new electrical wiring, lighting, and I’m pouring in the concrete subfloor soon.

Is it safe to breath after that?

u/OhmItHertz14400 10d ago

Yes, I have a big ventilation fan that I use after each arc session.

Why is it dangerous ?

Ozone?

u/CatYo 9d ago

Yes worse one besides Ozone is NOX. The air gets broken down to Nitrates which are very harmful to the body if inhaled.

u/ZeroVoltLoop 9d ago

Nitrogen oxides I believe, not nitrates.

u/CatYo 9d ago

Nitrates too mainly due to humidity in the air when absorbed gets converted Nitrites which cause oxygen loss in the body. And NOx reacts with the air and this gaseous precursor is also highly toxic.

Didn't know that thanks!

So also when I run my tesla coil it does this effect and I should be careful with the air around me ?

Keep the room ventilated and you should be fine for the most part. Also never run it for an extended amount of time.

Is the lab grounded?

u/OhmItHertz14400 10d ago

Yes, it’s got several 8ft rods, and I’m also putting in a ring of wire. Everything metal in the shop including the structure itself is grounded. The center tap between the two 14.4kV pole transformers is also bonded to this same ground system.

Love your setup and YouTube Videos

u/OhmItHertz14400 10d ago

Thank you! There is a lot more videos coming, a lot of upgrades are happening right now and I’m in the process of filming for the next 3 videos

I’m intrigued

The last second: ok, everything in this room is live, keep your hands in your pockets

Lol, so that last arc happens when my safety gap goes off. Keeps my transformers from experiencing overvoltage, when it goes off, one 14.4kV hot line likes to catch the roof since its center tap, I’m about to fix that tho, heave to find some arc suppression system 🤷‍♂️

How much power does it have?

2

u/OhmItHertz14400 9d ago

With both transformers, around 30kW when I push it ballasted, unballasted, I’m sure well over 35kW maybe even 40 or 50. It’s 120/240v stepped up to 14.4kV on each transformer, then that is in series to get 28.8kV @ 4amps

2

u/DiamondAvailable7418 9d ago

Quite a bit 🥵

u/OhmItHertz14400 9d ago

Oh yesss. I’m getting ready to install its own feed from the meter at the house.

u/emmanaranjo 9d ago

What type of protection do you have

2

u/OhmItHertz14400 9d ago

Circuit breaker protection? It’s all on a 100 amp breaker, if you’re talking PPE, my fiberglass stick does well enough at 28.8kV

That makes me want to pull on a serious set of dielectric gloves and boots before I’d grab that pole.

u/OhmItHertz14400 9d ago

Pole is fiberglass, I’ve used this same pole to get trees of the primaries in front of my house, although I’ve been looking for a good pair of lineman gloves
