The Gabriel Device, possible COP=8

[e2matrix]

Something sticks in my mind that I'm sure I read somewhere in regards to real OU devices.  It was something about making sure you always having a load on the output.  I'm vague on exactly where it came from and so it may or may not apply here but considering the results maybe you need a load on it before even firing it up?

Hi Mav,
Good progress, its a pity it arced before you could add the load.
I have a few smaller Magnetec cores to test with and I will be encasing the secondary in a thin mu-metal shield.
I need to try and get some transformer steel next week from work.  This should be ok to cut with aviation snips.
As long as I can show the same effect of reducing the primary current while increasing the secondary load then I will be happy to progress onto a mild steel donut such as the one you are using.
Would it be possible to get one made up from the same place you had yours done if I put some money towards your tooling cost?
Thanks
Meggerman

Guys, a remark on the frying of the secondary.

I am not sure about your winding ratio (see my reply #88 in this thread), but there's another reason why high voltage is occurring at the secondary winding.
The permeability of the secondary is very high relative to the primary.
This means that even if the winding ratio is 1:1, the coil values are not 1:1 but they need to be multiplied by the permeability ratio too.
This makes this transformer a high voltage one. So, be careful !!

Hello everyone,

This means that even if the winding ratio is 1:1, the coil values are not 1:1 but they need to be multiplied by the permeability ratio too.
This makes this transformer a high voltage one. So, be careful !!

The permeability act only on the magnetizing current not on the voltage which is defined by the winding ratio, coupling coefficient (k)...
Low permeability = high reluctance = high magnetizing current...
High permeability = low reluctance = low magnetizing current...

A circuit with a high reluctance and low reluctance coupled together have high magnetizing current...

A trick for the Gabriel device is to put a "Reactor"  (a reactor is a AC ballast preferably linear ballast (air gapped ballast) in serie with the input side to limit reactive current without dissipating real energy in the taoster...

I have made a lot of FEMM simulation and I have theorized a new device based Heins effect...

...
voltage arced on the secondary and shorted to the core, intresting since my insulated windings are the very outermost layer of the secondary core and can handle 600 volts... so even if it arced and fried my windings on the inside it should not be shorting to the outercore.
...

Make sure the two halves of the outer shell are not shorted/touching, otherwise it is equivalent to a shorted huge 1 wire loop secondary. It needs to be insulated at the joining edge.
