Strange way cook sausages!!!

I removed an old torroidal transformer the other day, and I'm going to have a go at replicating his high current, low voltage transformer

On You Tube ?

Mine is a 230V > 12V 180VA tranny, so not as big as his, but I reckon I'll still get a couple of hundred amps out of it.

The thing that somewhat surprises me is that their cable looks fairly modest in CSA and, although copper admittedly has a higher conductivity than steel, I'm a bit surpised that the cable is largely surviving whilst the lumps of steel get to white heat and melt.

Kind Regards, John

They say it's 95mm², and I'm sure it'll be getting pretty warm!

Just shows why the adiabatic equation on SWA cable is so important!

I must have missed that - but I have to say that it didn't look anything like 95mm² to me - hence my comment.

Kind Regards, John

Why bother? We will not find many 1000 volt supplies in the home since the demise of the cathode ray tubes in TV's.

I see his point about using the body as a conductor but still rather a pointless test.

 

[SimonH2]

Pointless ? Does there have to be a point to have some flashes and bangs ?

I have ot say, the screwdriver was quite impressive. I reckon by the time you're up to 50kV, leakage through the screwdriver could well be the least of your worries

I was genuinely impressed that screwdriver lasted all the way up to 50kV!

It was a CK driver. Ugh
