There are many good articles on the 'Net about this, but here's the simplest analogy I can think of that draws the difference between kW and kVA.
I know all that, my doubt is not with that. :-) What I don't understand is how a power factor corrector is going to save money for a client, unless the company measures the power factor at the premises. And here in my country they don't, unless your contract is for a high enough current, or it is an industrial installation. Maybe it is different in your country?
Some authorities raise the point 'where does this power go?'. Good question. Maybe heat?
Yes. Higher current, higher losses on the entire network.
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.
:-????
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.
How does this relate to us? See https://en.wikipedia.org/wiki/Switched-mode_power_supply#Power_factor for a start.
Interesting. But the issue there are harmonics, more than the power factor. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
