Reactive power - Reactive Generator research from GotoLuc - discussion thread

[conradelektro]

Here you can see how Jean Louis Naudin made a faulty measurement (measured too much power output) because the resistor also was inductive (not only resistive):

http://jnaudin.free.fr/rvproject/html/ugentest22.htm (NOTE TECHNIQUE du 26 octobre 2012)

He not only had to deal with the induction of the resistor but also with the so called "reflected HF power" which falsified his measurement http://jnaudin.free.fr/rvproject/html/ugentest23.htm

The subject of Naudin's test is not relevant for this thread. I cite his pages because it shows the difficulty of correctly measuring HF output from a coil.

The pitfalls are "induction in the measurement resistor" (too much power is measured) and "reflective power" or "missmatch loss" (too little power is measured) http://en.wikipedia.org/wiki/Mismatch_loss (more pronounced at higher frequencies).

May be it helps.

I have tried again - this time with the circuit from this post (i.e. with the load on the secondary):
http://www.overunity.com/14013/reactive-generator-research-for-everyone-to-share/msg377250/#msg377250

I found that if I calculated the power across the load *assuming* a power factor of 1 - then it appears to be OU.

How did you do it exactly? Mind posting your results?

Measuring the rms voltage across a non-inductive load resistor should yield the correct power when using: v^2/R.

All the calcs are complicated, and so I did what I suggested above - and used a FWBR. This time the output was sensibly UU...

Remember that you will lose some power to the diodes.

I was using a standard low-power resistor - 150ohms - probably wire wound - not sure...
As the instruction is to use only 1-2 watts - i thought it'd be ok. It was.
I didn't use the variac this time.

What are the specs for your MOT?
What value cap did you end up using?

Ok, I'll run thru the test again later, and fully document it...

Thx for the other info too... Will try to include it in my tiny brain...
