An Article: An Introduction to Power Factor

Horrible.

Plus you have not quoted the basic definition of Power Factor.

Do YOU even know it ???

.......... Phil

This need a lot of work.

KodKodKod Learn> Hi all,

If the reader knew enough to understand the first equation, they wouldn't need the article. You do not define imaginary current, nor power factor (in a general, conversational) way before you launch into math. The math should quantify what is first understood, conceptually. Your approach also does not include harmonic power factor, but only phase shift power factor (without hinting that it is covering only one of two possibilities).

Do you need a consultant?

Dear all,

Thank you very much for your comments! (especially to John)

We have re-written the article

Thanks again!

I still think you need to start with a question (the opening "question" is just a phrase) and say what displacement power factor is. The current drawn by a reactive load has two components. One is power consumed by the load (or converted to some of the form of power, like mechanical). The second component represents energy that is stored by the reactance and then returned to the power source, twice per cycle. So the line current represents power passing one way, from source to load, and also energy sloshing back and forth between source and load as short term loans. The combination of both energy flows produces relative a phase shift between the line voltage and line current.

If the reactance is inductive, the energy is borrowed mostly after the voltage peaks so the current peaks lag the voltage peaks. If the reactance is capacitive, the energy is borrowed mostly on the way up to the peaks, so the current peaks lead the voltage peaks.

Then the math shows the details of these processes.

The first line (in red) isn't a question, as JP points out.

I think your page is aimed at beginners, and therefore you should avoid the exponential notation; stick to simple SIN(wt+theta) notation.

Regarding the reference you give at the bottom; what is PAQ 93? If you want your readers to actually find this reference you must give more description.

Finally, you would do well to find somebody whose native tongue is English to polish your language.

I'm not seeing that.

Probably browser dependent which indicates the page code needs sorting.

That's what I figure. But I'm not willing to break my browser to sort it. IE6 and TB1.5 these days that's about all I worry about. The others are in the >5% range.

The overwriting problem is rare and generally only seen on sites created by amateurs.

....... Phil

That's exactly right Phil, I'm not. You fit into the >5% classification, then.

But don't feel bad, Phil. You have good company. The Mac users with OS7 are right in there with you. They also claim that "only amateurism" creates pages they can't see properly.

Yes, pages can be created so that you see them properly. Too bad they are designed for IE4 & NS3.

Here is a real one.

Sure has a monstrous axe to grind over something.

Tiny c*ck syndrome - I bet.

Thanks Phil. I needed that. I'll be sure to tell anyone here to plonk you.
