Easier is P=Tw
w being omega, symbols don't seem to work here.
On the other hand, you could measure and analyse your supply voltage and get back to me when you have done that.
And, FWIW, the oceans account for 1,314,829,398,016,000,000 cubic metres of water.
Might I politely suggest that you do some measurements and then you might be in a position to validate your points.
Care to share?
The world is SI.
I wouldn't. So we may have to agree to disagree.
But you might like to consider where that 5% comes from.
You might be surprised. And it depends on what you call clean.
I was visiting Toshiba Houston a few years ago. The supply was not all that great when I checked it.
That's not actually correct. The UK commonly uses 11kV to 400V for distribution. I have measured harmonic distortion at the 11kV level that was outside the limits of what was deemed acceptable.
Tektronix TD210 with the optional serial port.
I use a digital scope with a backlit LED display.
It gives excellent results and I can dump the data into a spreadsheet for later analysis.
Looks like third.
Yes. If you over correct it is likely to increase the voltage.
Yes, I know about IEEE 519. We ship equipment to countries where we have to comply.
Bear in mind that's current, not voltage.
Third actually and some resonance.
It's a single phase system.
I do a lot of calculations for my colleagues in the lighting division. Single phase dimmers. Third harmonics dominate.
This current waveform was also taken at home:
I don't imagine ours unique. Multiply that by the number of residences fed...
Yes, the lower the supply impedance the lower the distortion. If the supply was infinitely stiff there would be no distortion. But real life kicks in.
I'll add something to your comments about...
Non linear loads.
A picture that might help.
The blue is the load current. I've used per unit values for the graph. Any multiplier can be applied.
Depending on the size of transformer you might have a problem getting a contactor to operate in that time but I wouldn't have thought it critical anyway.
Ultracapacitors can do this. But one thing to remember is that faster charging requires more power. For example, charging batteries for EVs takes hours from a domestic supply because of its limited...
You are billed for energy consumption.
It's called brain fart.
kWh isn't a measurement for watts. Its energy.
