COAX TPU...

Current transformer?

Not likely as the winding around the circumference is reversed half-way around. This would cancel any output developed from axial current flow.

Also, the small toroids on the TPU each have four wires exiting. A CT only has two unless it is multi-tapped.

I think this device is a method of controlling inductance/saturation while preventing transformer coupling between the control and signal windings. In other words, a mini TPU.

>>Edit

Now there is a thought.
What if you had no initial source of power in a primary winding but still wanted power out on the secondary of a transformer?

You vary the density of the Earth's magnetic field within your secondary with a perpendicular control winding. With that coil orientation you would be canceling the coupling between the control and secondary but still vary the inductance of the secondary.

Of course, early tries would require magnets to concentrate the Earth's magnet field, in a radial fashion, within the secondary.

HI all,
A current transformer does have 2 coils, 1 for the metering and typically a 1 fat wire through the centre for current measurement.
If the winding is reversed half way then correctly said this will appear to cancel the magnetic field but it generates 2 opposing fields, net result is zero overall . It also generates an electric field which (tesla wave theory) causes induction to any metallic object in the locality. Conservation of energy dictates if power goes in to a device it must be converted to something, it cant just disappear can it?
It may be fed dc as suggested for a flux gate control as used for lighting control systems of last century.
the core itself, do we know that itsnt a barium ferrite ring magnet? Im thinking along the floyd sweet device as this had a similar winding for energy collection (phase conjugation, cooper pairs). It seems that most devices assumed to output overunity characteristics utilise this within them in some way.
scratching at the starting post!!!!

Huh?

If you mean the 'fat wire' is the conductor being monitored, then yes. That is not part of the CT.
If you mean a common CT has two actual windings -- sorry....never seen such an animal. Having spent two decades designing control switchgear I think I would have run across something like that.

hi bep,
yes the fat wire goes through the centre of the torus is a part of it  its only a half turn. anyother wire near to it is not part. sorry if it came across wrong. think about the torus in a soldering gun. the fat wire in reverse, quarter of a volt 100's of amps.

If you look close at the FTPU toroid, you will notice that there are two black and two white wires coming out of the toroid center. The white wires are thicker then the black wires. Why since both coils are using the same gauge wire? The two white wires look identical to the white horizontal loop wires. Why? Tried discussing this some time ago hoping some could shed some light or possible logic on this.
