Induction motors and capacitors lowers amps "consumption"

I urge everyone working with systems like this to do a full and complete study on power factor, and to get the right metering equipment, (kwhr meter, and a kw/kvar/kva/pf meter) you can find these things on ebay.

I totally agree.  A Kill-a-Watt meter cost less than $25.00.  We have two of them.  Kyoat

Hi everyone,
I'm still on my remote job and have not been able to (hands on) continue my research.  Although my partners are hard at work and have made tremendous success.  We will post our newest results as soon as we can weed out any errors.   We don't wish to receive the negative sounding replies that some feel they need to post.  Ignorance seems to be a trait of some who wish to put others down with out explaining their reason for their response.  I suppose this somehow makes them feel "smarter" or "better" but in my eyes, they are just plain ignorant individuals.


I (not we) need help!
I'm not an expert, but I keep getting conflicting answers when tyring to answer some of my questions.  So I thought I'd post them and maybe someone out there will be able to help me out with a logical, easy to understand explanation.

So here's a few of my questions that I'm tyring to find answers for.  Anyone willing to assist in the correct answers will be greatly appreciated, and not forgotten!  PLEASE EXPLAIN ANY ANSWERS

1)  1 Horse power (electric motors) = (I've been told 746 watts is this correct?
     1 Horse diesel is greater than 1 Hp Gas...... how does an electric motor rate as compared?
     is it greater or less?  Please explain. (A 15KW generator will work with a 15 HP diesel, but
     requires at least a 24 HP gas motor.  (so therfore HP is not an equal equation)

2)  1 horse power (electric motors) = (I've been told 550 foot pounds per second) is this correct?

3)  This question deals with gear reduction verses horse power.
    3A)   If I have a 1 HP electric motor hooked to a 2 to 1 gear reduction gear box,  how much
            power do I have at the slower end?  Is it still 1 HP, or is it 2 HP? (less frictional losses)

4)   If you hook up a "grid inverter" to your local power provider, and let's say your power source is
      15 KW of power, as opposed to your power provider's power of let's say 200 Amp service
      at 220 volts, why doesn't this "fry" your inverter?
     
      4A) If this same inverter is getting it's power from a XXXXXXXX that gets it's initial power
            from your local utility, will this cause a harmonic interference within the two
            systems?

5)   Any help with any of these questions will be greatly appreciated. 

Thank You.... KYOAT

1 hp is in fact equal to 746 watts

diesel:

gasoline:
http://www.generatorjoe.net/product.asp?0=200&1=618&3=2922

Generator engines have to be at least 20% stronger in hp than the electric equal hp, so 15000/746= 20hp
20hp/.80= 25hp, that way the engine can handle a load being dumped on it with out stalling the engine.

GAsoline or diesel HP is HP. The difference is in the amount of fuel used to produce the hp, and the amount of displacement of the engine.

2.) yes 1 hp is 550 foot pounds for one second. Please see :http://www.onlineconversion.com/power.htm

to convert just about anything into anything else.
! HP is equal to the energy needed to lift 33000lbs 1 foot in 1 minute.

3) you would still have 1 hp. think of mechanical hp as a function of rpm and torque. high rpm and low torque = 1hp, low rpm and high torque = 1hp.

power is universal, whether you lift 10lbs 10feet or 100lbs 1 foot.

4) your service has a maximum handling of 200 amp at 240v. but you only ever use the amount you have turned on at any one time. Which can be very low. Zero in fact. An inverter has the ability to limit how much power to outputs, and so limits itself to 15kw. Instead of blowing up it cuts back its output voltage.

4A) the inverter is designed to harmonize itself with the HZ of the system, so no it should not. Because the inverter turns DC into AC, and dc has no harmonics to it.


5) Umm your welcome?, not sure how to answer that one
