Reactive power - Reactive Generator research from GotoLuc - discussion thread

Here is the discussion and continuation thread from GotoLuc´s Reactive Generator Research thread:

Hi Luc,
I just googled the surcharges for reactive power usage and there are
some power companies, where you pay for it a surcharge and it also
rises, the more reactive power you use:

This one shows it in the last table there.

Power factor less than               Surcharge
100%
    but 90% or more    Nil
90%     but 88% or more     2%
88%     but 85% or more     4%
85%     but 80% or more     9%
80%     but 75% or more     16%
75%     but 70% or more     24%
70%     but 65% or more     34%
65%     but 60% or more     44%
60%     but 55% or more     57%
55%     but 50% or more     72%
50%           80%

Hi Luc,
maybe you can still address this:

Please let us know, did the scope show the real current on the shunt
or was its real value 10 times higher in your last video ?

So what was the exact real absolute value of the current in your last test ?

320 mA or 3.2  Amps  ?

Many thanks.

Hi,
   there's obviously a fair bit of power coming from somewhere to heat the transformer
up enough to cook an egg.
  With all of these things there's always the ubiquitous grid supply, battery or signal
generator. I imagine without the grid you'd just have a lump of cold metal.

Let's look at Luc's scope shot again.

Notice that the CH2 trace is indicated as current; specifically 132mA/DIV. The problem with this, and unfortunately this invalidates all of Luc's data and conclusions, is that he is NOT using a current probe in the video. He is in fact using a standard voltage probe across a 0.1 Ohm resistor. You can not use a voltage probe and tell the scope that it is a current probe and scale it that way. This is not correct.

So not only will your measured current be completely erroneous, but the phase of the trace may be inverted as well.

The attached is a picture of a typical current probe, and is what Teltronix means when they refer to "current probe" in the manual (see p8 & p105). Current probes clamp around a conductor.

Please redo your measurements using CH2 as a VOLTAGE probe with the appropriate attenuation setting.

Stefan,

I also agree with you, the upper part of the math is what is used and the lower part is what is returned.
The scope has the ability to set a probe for use as current or voltage. Multiply the current by 10 as CSR is 0.1 Ohm.

Not quite. If you are setting the scope channel for current, you must have a current probe connected to it.
