Yes. When there's no overload/EMP we want the normal
voltages to get to our devices, right? The current varistor technology has a tiny current, perhaps in microamps or less, that occurs at normal
voltages up to say 240V. It's small enough to not be a big concern or cost but it's not exactly zero. Obviously zero losses would be even better,
but the thing we want to avoid is spending an extra 10% on our energy bill on a large leakage current, larger than the current varistor technology.
Then increase the voltage of the black transformer past 240 volts and show that the output of my system is constant at 240 despite the black
trans being at 2000 volts, 5000 volts, 8000 volts, and 12000 volts?
I would suggest the following. Make the black transformer input/output in 5
steps as follows:
1. 2.4V / 240V
2. 5.0V / 500V
3. 10V / 1000V
4. 30V / 3000V
5. 60V / 6000V
At each one of these settings, we want to know how much of that voltage is getting to the LEDs coming out of your white box.
The first number would of course be the variac setting if it was calibrated to not be one tick off. Or you could just set the variac accordingly
knowing it's one tick off, if it's hard to calibrate the dial. So when you set for 60V you'd actually go 1 tick under 60V, since "zero" is one
tick under zero.
Of course, you can do more steps if you want, but I think 5 steps is a minimum. If you want to go higher that's up to you but you've already
demonstrated this voltage range is within the capabilities of your setup so that's why I suggested up to 6000V. I don't know the ratings of your
While you do this, you could just alternate the video between the variac settings, and the voltmeter hooked up to the LEDs "output" from your white
box, to show what output voltage you get at each variac setting. Unless you can figure out how to get the variac dial, and the voltmeter into the
movie at the same time, that would be even better if we can see what the voltmeter does when you turn the variac.
I really thank everyone for pointing out the bad parts I'll continue posting videos until everyone is satisfied.
You have to understand that when I shop for a surge protection device, I'm looking for performance characteristics based on current Varistor
technology. If your technology has significantly different performance characteristics, that's ok, but you might need to explain what those are and
how it might be better in some ways and worse in some ways then what we are used to with the Varistors. But as mentioned earlier, I wouldn't want a
device with a large leakage current under normal operating conditions, and with Varistors I know it's only about a millionth of an amp or something
like that. (That's a microamp). And I also know I don't want the output voltage to go over 1000V even when the inputs are much higher than 1000V. So
those are two of the key performance characteristics I look for.
