Reactive power - Reactive Generator research from GotoLuc - discussion thread

[gotoluc]

Sorry Poynt but I'm building something and don't have time to do this now. I didn't have time to do it yesterday either but I didn't think it would of taken so much time. So this is why today I ask you to just go ahead and explain how it all works.

If you can't do that, then I guess I'll have to wait for the video.

Thanks for your time

Luc,

With reference to your first video with the 10R resistor and 5uF cap as load, your DVM is showing 2.25V across the resistor which gives a current of 0.225A. However, your scope reading is showing 229mV across the 0.1R shunt resistor, which gives a current of 2.29A!. Your scope probe setting for channel 2 looks wrong here by a factor of 10x the actual voltage across the shunt resistor. Can you please re-display the scope shots with this corrected.

Although there is a slight change in amplitude of the channel 2 waveform when a capacitor is added, your watt meter is not showing any appreciable change when the alternator is loaded with a reactive circuit. This may to some degree be due to the watt meter not being designed to measure reactive loads accurately and being insensitive to small reactive load variations, especially given the highly reactive nature of the prime mover.

Kirchhofs law does not apply with non- conservative fields.


Here is an explination

and here is a video lecture of which go to minute 33 onwards, it will open your minds "or blow them as the case maybe"

No error, channel 2 setting is set at x10 so the math is actual watts value (no need to multiply by ten)

If you don't have time right now to do this Luc, then why are you asking me to explain it now? It's as if you think I have all the time in the world, and that your time is more valuable than mine.

Reading and understanding the page I linked to IS A BIG PART OF THE EXPLANATION. And you know what? It's not difficult at all! So when you are more interested in understanding where you are going wrong vs. continuing to plow blindly forward, I've given you a place to start that quest.

Parts should be here today or tomorrow, and videos will follow soon after.
