After a grewling amount of cutting metal with jigsaw, grinding, sanding and winding wire etc, got this contraption ready to start testing.  Used jb kwik weld to join the bottom to center and outside portions of shell.  Outside winding is 112 turns of 24awg wire I had laying around, will see how it works before committing my good 18awg wire to the project.

That's looking good, but it seems I do not understand the GD... I thougth both, primary and secondary are inside?!? What's that outside winding?


Also, permeability is altered by mechanical and heat treatment locally, a core may or should be tempered @ 250°C for a half a day to equalize permeability.

Using variac so far seems like normal transfo.  Using main secondary winding for load with output at 120v into 100w incandescent bulb I get 1.46amps at 97vAc on the input.  Starts humming at about 1.5-1.7amps where saturation seems to start however didn't have scope on current waveform to be sure yet. 
At least this thing seems useful unlike the BITTs I tried to build.  Will post more when I can get scope to measure phase angle and real power.

Dieter;
The outside wind is primary, I put few different ones on inner core for flexability, inner ones are secondaries.  Did try two shorted 10turn winds on inner core and got no output with 35vac in, looks like that idea is bunk so far, will see what scope shows with those two 10t windes left open. 
Mag was reporting that shorted turns got rid of reflections, not consistent with what I am seeing thus far.

Scope is in parallel with yellow current meter measuring current on input.  Black digital meter is on output volts into two 60w bulbs so 120w approx on output while 1.69amps on input (fairly clean sine wave on input current) at about 103vac in.   With load open Circuit got about 135vac on output with distorted current input wave showing about 1amp on input current meter. 
Also included shot of raised input volts raised until input current distorted showing unusual distortions in the input current wave(same 2x60w bulbs as load).  Next update when I put 2ch digital scope on here to measure phase between input and output and calculate real input power.

Anyone got any idea why all my pics show upside down?!  Sorry for the eye strain, wasn't my intention.

That's indeed strange. Maybe try an other export program. I am currently using Artweaver, which is ok for small tasks. Gimp is a bigger download, but more "en par" with photoshop.


Interesting wave distortion, maybe a feedback. kind of.


Looking forward to see Power factor...

You say input is 100 volts and 1.69 amps, output is two 120 W lamps, right? So that voltage acros this lamps?

Yes, two 60w bulbs in parallel with output at 120vac.  Bulbs are only rated at 120vac so that is the only output volts you can run at and be fairly sure you know the power unless you are measuring out current and volts.  Incandescent bulbs may be quite nonlinear, I know their resistance changes a lot when the filament is at different temps.  Will need to borrow that 2ch scope again to get any more meaningful data. 
Oh, just realized that in an above post I said it was mags that suggested the shorted turns to reduce reflections, that is incorrect, I meant to say Mavendex was the one that suggested shorted turns.

Isn't the shell-core also a coil, a one turn short circuited one?

Dieter;
The inside top edge of the shell is insulated between the two pieces with electrical tape to prevent the shell from as you mention being a shorted turn itself.  Also I insulated the plates of steel that comprise the shell from each other with packing tape to reduce eddy current losses which will eat up power like crazy and produce heat in the shell if not prevented.  I just realized that putting the main secondary wires through the shell in the way I did must be causing losses as well, should have current leaving through same opening that it enters or else you have shorted turn in essence around the wires in the shell itself.  In power panels you always run neutral and hot through same opening in steel enclosure or else metal will heat up around wires.

Boots,


Ok, I see. People often use a steel, copper or alu pipe as a core substitute, not knowing about that (and the enormous amperage in such a coil). Didn't know about the Hot/neutral wire thing tho.


When will you have the two channel scope?

Hooked up scope last night, very disappointed as i only get 10 deg phase angle between current and volts on input with 120w output at 120vac out into two 60w bulbs.  Power calc gave 158w in with 120w out. 
Tried to compare phase of input volts to output volts with same 120w load but it appears to be in phase or 180deg out depending on polarity I connect scope probe.  Tesla patent mentioned phase shift but I am not seeing it at all, anybody know if tesla actually built the transfo described in the patent?
Perhaps if I could run it at 800hz or something phase shift would appear?  Any ideas on this are appreciated.

Hey RB

I used to follow here but it died out.

What I remembered was that the input needed to be variable to adjust the phase shift. If the input is to strong, on a particular build, not much phase shift as it over powered the shielding of the shield. And too little input, no output at all, due to not being able to produce flux beyond the shield. Do you have a way of varying the input? 

I believe Tesla said the the transformer needed to be designed for a particular input to operate properly. So if you have it built already, then you need to adjust your input to match that build. That is why Gabriel used the toaster in series with the primary, as it happened to work as the input adjustment needed for his build. ;) Freq should not be to important, just not too high for the inductances.
