"I must agree with EMdevices that you get charged only for real power. This is how it function in slovak & czech republic and I think also in another countries. According to law PF must be in range <0.95;1>. This is particularly important for big electricity consumers. If their powerfactor is less then 0.95, they can be charged up to 50 million czech korunas which is almost 2 million euros! I think that similar law is established in Slovak republic because we lived many years in common state.
That throws bad light on winsonali and his "expert" knowledges."

No, it throws bad light on your knowledge, you may want to research power factor. In power plant operations reactive loads are not a real issue as electronics handle any corrections and the reactive load is spread over a large area of consumption--the power grid. Medium and light consumers (you) however can have drastic reactive load swings locally, every time an inductive load comes on line the power factor changes drastically. An average installation may have a steady PF near 0.8-0.95 however if any motor,transformer etc... comes on line the PF goes to 0.4-0.6, I know this as fact as I spend many hours near industrial electronic power monitoring equipment. Ali is also perfectly correct in stating cheap DC/DC converts have a horrific PF and I have seen measured efficiencies near 50%. There is also the "dirty power" issue due to poorly designed (cheap) input power sections on electronics and the large scale move from transformers to DC/DC buck/boost converters. This dirty power is basically harmful high frequency RF(radio frequency) which can turn most of your house wiring into a low power short range RF transmitter, again I measured my house for RF and I know this as fact.
Maybe you newbies should check your facts first,lol.

I insist on my previous assertion, that Ali used incorrect formula. Check some textbook about electric power, wattmeters and so on.

realpower = V * I/pf this is what Ali has written. If this was true, then purely reactive element, for example high quality capacitor, should have realpower approaching infinity:

realpower = V * I/cos(90) = infinity!!!

This is obviously not true, because capacitor as purely reactive element has zero realpower:

realpower = V * I * cos(90) = 0

This is correct formula.

I agree with you that PF is not always near 1 in typical household, but its impossible by compensating PF get your electricity meter slow down. If this would possible then shops would be full of “magic” boxes that can reduce your billing by several tens percent. I dont know about something like this happening.

Yes I agree he used a wrong formula, nothing to argue about there. It's kind of strange that he made such a basic mistake.

Most often the difference between the possible and impossible amounts to nothing more than knowledge and understanding. Inductance acts like the mass on a pendulum displaying the property of momentum. Do a little experiment for me and yourself. Attach a mass(inductance) in between two springs(capacitance) or elastic bands then attach one end of this apparatus to a wall or doorknob. Now, hold the other end of the spring and start pulling and releasing the spring so that your pull/release is in time with the motion of the mass, this is resonance---note the frequency of your pull/release. Now double the weight of the mass and try it again, you will find the frequency has changed. In order to keep the frequency at it's original value of the smaller mass you will have to pull harder and faster on the larger mass---extra work. The power grid in North America is locked at 60Hz so you cannot change the frequency, when inductive loads are attached that are not resonant at 60Hz extra work(current) is required just like in our little experiment. Instead of doing extra work you can change the stiffness of your springs(capacitance) to compensate for a changing mass(inductance), the resonant frequency of the load can then be matched to that of the source (resonance), this is PF of 1. The reason few people utilize PF correction equipment is because it involves high power/high speed electronics usually, this is very expensive. The fact of the matter is most people are ignorant to the facts or they just don't give a damn, ask your self why almost nobody here understands what PF is or how it works? I have one simple rule----- If I don't understand something--anything, I research and experiment until I do. Very simple concept.
