However the obvious cost saving lies in the fact that power factor correction means less current is drawn for the same consumed power. Most places bull by the amount of current used, the kilowatt hours. Recall voltage is the constant.
AHH! I understand now... so that's it. Yes, it makes sense. They measure the current, not the actual power. Or at least, those saver gadgets assume that. I don't know if that would work here, though. The new meters installed by the company are not electromechanical, but electronic, with a microprocessor. They do some kind of integration and calculation, and send the data to a remote data center automatically; it would not surprise me if they measure the voltage and phase. I have verified that connecting a load via a half wave rectifier, meaning half power, is measured correctly. I don't have, currently, a heavy load that can be adjusted with a thyristor, to test. Or something with a heavy power factor. It is possible they do measure actual power factor now. I don't have the specs :-(
IsquaredR losses still apply. In fact to get the same power, more current has to be drawn since voltage is a constant. Other think it produces some kind of electrical back-pressure on the generator.
:-????
Me too. It seems the phase shift is noticeable back up the line ...
Yes, of course it is. But it is averaged with all the loads, and they can compensate on the stations.
Certainly the utility company can tell if you are running with an abnormal load factor.
Only if they place a measurement device at the entry point to your premises.
As I said, I don't see them doing that domestically.
That was my understanding, yes. Till recently, at least.
Never the less I see on my bill the assumption of a "Loss factor adjustment" of 1.0376. I presume that is "assumed" rather than measured as its the same from month to month regardless of my use of heating or air conditioning or the months when I need neither.
Yes, it must be assumed. My bill doesn't say.
I woold *expect* industrial consumers to have it measured.
Yes. - -- Cheers / Saludos, Carlos E. R.
