Bi-toroid Transformer of Thane C. Heins

Measuring Loads

Here is a video that is simple to understand and is only meant to be used as a tool for tuning. This video is not my setup but could be used by someone to loop with. Remember at the end of the project when more is coming out it is power that must be converted back to a form that powers the input.

Then the extra can go to a resistive heater element.

The one I am setting up is a 1.2 amp AC window unit that runs on 120vac.

Each motor runs very quite and are the same. I need a small system to run my tiny amp. It only needs about 60 watts input and the amp produces and output of 50 percent of that figure. So say 20-25watts.

It will be sooooo evident when I hit a node when the rotor is relieved.

This is the same as a wind turbine. Or even set it up off of a car alternator that is powering a load to an HHO cell pack. The claim is that the bi-toroid
Would double or triple the alternators capacity or any motor.

This simple setup could allow experimenters to test and tune without a scope.

Resistor?

So what am I to use? I need to measure and this will be my first time using this resistor and you say I can't use it now

Still this is good to know about the resistors inductance.

Mike

I've found the source of my negative power factor. Don't underestimate the reality of stray inductance or capacitance. My 1 ohm current sensing resistor is of approximately 15 uH. This means at frequencies, of say 50 kHz, that I'd have 2*pi*.000015*50000 = 4.7 Ohms of reactance. Well.. I'm only trying to sense what is going on in the 1 ohm of resistance... This additional factor of reactance totally skews my results and make any of my previous statements null and void. The more reactance your current sensing resistor has, the closer to 180 degrees your measurements will be. Don't let this one bite you.

I'm going to remove my videos as they are misleading. I'm not done with this endeavor but at least know how I must proceed with measuring.

Probes

Hey Dog-One you mean like this one will fit my HP 54100D??

Hey Dog-One you mean like this one will fit my HP 54100D??

If it will work, for $100 it's a bargain.

I'm sure with most HP gear you can check compatibility. I highly doubt there would be anything about it that makes it unusable.

Good find.

Hey Dog-One

I wanted to ask you a question about my amplifier.

I have an older (Like Brand New) version rack mount record player for LP records.

It has the standard inputs in the back but also the phone-O inputs that have a higher gain. Which one should I hook my generator to?

I can try them both to see if distortion is present.

Good find.

Why does it have two cords? One terminates to the digital probe on the end and the other cord just stops? Do you know if this is a double probe?

Coming At Dog-One

Here is the book on that probe and looking down the page I don't see a scope.

Can it still be used on a scope?

Guitar

I also have several larger amps for big speakers. 800 watt pyramid, 200 watt, 50 watt and more.

I want to keep them in one piece so i better use the small one first.

I have a sound setup for playing guitar and singing.

54100D Scope Book

This is wrong. I meant this is the book for the probe





Here is my scope.

Looks like the second cable hooks to the 1142 power control module. So this diff probe must not use batteries, i.e. it has its own power module. Does the 1142 power and control module come with the eBay package? You'll need that it looks like.

Don't use the phono input as this has a pre-amp on it. Use the line level (1 volt) inputs. You should be able to lower the output level on your signal generator to this level without issue.

If your amp is anything like mine, it will have an overload indicator on it that tells you when you are clipping the signal. Just reduce your input until this goes out then use your master volume control for how much power you want to inject into your SFT.

Mike, I'm unsure of how you are going to use a differential probe to get an accurate current reading. I think we'd probably be more interested in current probes? Maybe I missed something..

Yeah for $500

Ask Dog-One he thinks this can eliminate some ground and other measuring troubles. I don't think I have a probe like that anyway. I have a 1 ghz probe and some slower that come standard with the HP54100D.


Talk to me Dave. I need to hear more on the possibilities with current probe hookups and so on. Did you come up with a better circuit yet?

Maybe use a carbon resistor? Just a guess.

I agree, good coaching Dog-One


Do you measure using a differential probe without issue?
