Watts vs Volt-Amps - huh ??

[SunEagle]

True but much easier to just use the Power Factor where Watts = PF x VA.

Doesn't require a calculator, only a 5th grade education.

Boy. There is always someone smarter that likes to give me a poke.

I do use the formula to determine how much kvar is needed to improve a poor power factor.

Like you said the math is easy and used in many applications.

The formula is also used to calculate power factor where the based is kw the height is kvar and the hypotenuse is kva. The angle between the kw and kva is the % power factor.

Correct any unit of measurement works. Like building a foundation for a building or laying out walls. It is the exact same formula used to find the relationship of AC impedance and resistance relationship.

Or any numbers for that matter
In a right triangle base squared + height squared = hypotenuse squared
Very useful when squaring up a rectangle by yourself.

Yes but 3 squared + 4 squared = 5 squared
The Pythagorean theorem

Correct to make a perfect right triangle is what any carpenter knows. Take 3 toothpicks. One 3-inch, 4-inch, and 5 inch. Lay them down with the ends touching to form a right triangle, and you will have a perfect 90 degree right triangle. Very simple basic trigonometry.

lol i was really really trying to understand........ but i got lost when 3+4 = 5

3 + 4 does equal 5. Any carpenter or steel man will tell you that.

I chuckled when I first read this post. This is pretty much a DIY forum and the posters looking for help have ZERO electrical knowledge and all this is is GREEK to them and will never understand one bit of it.

OK!

Maybe not drop out of the conversation just tone down your attitude that anyone that does not believe in what you believe in is old fashion or gets a profit from the fossil fuel industry.

I have been working with solar pv systems since the mid 70's. I truly believe in this technology along with finding the holey grail of batteries. I also know that people who think renewable energy sources will provide us with 100% of our needs do not know the rest of the story. Being in the electrical engineering and power distribution field for 40 years I believe I have learned a few things that can and can't happen with our current technology.

So instead of attacking others or using fear tactics with reference to radioactivity and those nasty fossil fuel pollutants try to keep an open mind while we help you learn more about this technology. I am on your side and want this technology to work but I am also pragmatic and realize that wishing for something to happen and learning how to make it happen are two different things.

Fair comment, point accepted.

Think about that a second or two. Those that put McCarthy down was from the Screen Actors Guild (SAG) which is composed of actors, news media, and broadcast professionals. They now have their man in office. That was the start of Political Correctness and censorship in the USA.

I think this thread has wandered off topic into an area better continued in the General discussion forum. Just my opinion.

I then pointed out to my child that the person residing in the white house (he who must not be named) is hell bent on redistribution of wealth. McCarthy wasn't such a witch hunter after all!
You think they pointed this out in school? Not a chance!

Boy you're not kidding!
I have a teenager who I was helping study history recently. The book discussed the roots of communism and Marxism where it was described that the main tenant of Marxism was redistribution of wealth. A couple chapters later McCarthy was discussed and demonized for his "witch hunt".

Anyway, does anyone use capacitors to improve the power factor of their load?

Yes capacitors will improve your power factor, but they can also worsen your power factor depending on the amount of harmonic distortion is on your power distribution system.

The harmonics are generated by electronic equipment (computers, ups, inverters) and variable frequency drives for your motors. If you don't install capacitors with harmonic mitigating capabilities you may be just wasting your money.

OOPs my bad.

Just kidding The crack was about us not you.
