Reactive power - Reactive Generator research from GotoLuc - discussion thread

All the information needed was given.

Those on the 220v grid will have more success in getting 0 Watts reading because MOT Primaries have more Inductance.

It you knew what a Power Factor of 0.08 was you would not say the meters are faulty.

Hopefully in time it will become easier to replicate and understand

Well, if it was, then please accept my humblest apologies for having missed it, and please answer the question.

Luc, I've replicated what you posted here, apart from different resistor values (which you suggested yourself anyway):

If I'm doing something wrong, then perhaps you would tell me what it is?

Is it because Hob's meter was reading 0 watts? Is that why what he did was 'right'? Surely that's a faulty meter... He even had two to show the discrepency...

I think Hob's meter has a resolution of 3W, and the power being used is probably hovering right around the 1.5W mark. That would explain why it is changing between 0W and 3W while in steady state.

@Luc:

It is ludicrous to rely solely on a $20 power meter that wasn't designed to be accurate down in the range that would be considered "dirt" by comparison to most average loads.

Everyone knows what a PF of 0.08 means. It means that you are trying to find a needle in a hay stack in terms of power and PF measurement. And you are using the wrong equipment to boot. You have a decent oscilloscope at hand so use it. I gave the diagram to measure both the input power and phase difference. Once you have that you can then use the scope to measure the rms voltage across your 1k load resistor to get the power dissipated.
It's then a simple math operation to see if you are OU or not. Right?

And you would be wise to get rid of all those wirewound resistors. Unless you are using them on DC circuits, they are trouble. Must I send you a proper 1k and 0.1 Ohm power resistor?

Please upload your video demonstrating OU with this simpler circuit.

Hiu Tim,
do you have a ground problem, or why do you have these ringing wavforms ?
Is a scope ground not connected or is your LC resonance frequency about 100 or 150 Hz, so
it is close to a harmonic beat frequency ?

I think Hob has now shown the effect also clearly in his video but these 2 Wattmeters have to be compared more , what powerfactor does the black power meter show ?
Also would be beneficial, if Hob could show scopeshots.

@poynt99
I don´t think that the channel 2 in your diagram needs to be inverted as both scope channels have the same ground location in the circuit...right ?

Hi Stefan,
  I think the noise is coming from other things running around the house - like central heating pump, fridge etc... It gets less as the voltage / power throughput goes up in the circuit.

I've connected 2 scopes to the circuit - they both show the ringing...
