KVAR energy saving - Electrician Talk - Professional Electrical Contractors Forum

has anyone ever heard of kvar energy saving to reduce your power bill/consumption by correcting power factor? if so, i would like to hear your reactions and opinions

Crap, horse sh*t, junk, rip off, screwing your customer, criminally prosecutable sterling, snake oil, waste of money, bunk, road apples, black magic and if you really want my opinion well give me a few to get my thoughts together.

No do tell!

EMC · 05-01-2009, 08:39 PM

but, its got a 12 year warranty and a 10% savings guarantee

Rockyd · 05-01-2009, 08:39 PM

Give Brian a gun! I am of the same opinion. Kvar can only be dealt with in large industrial and commercial settings, motors in particular.

So you didn't install one on your service?

**brian john** · 05-01-2009, 08:56 PM

THis subject has been dealt with here and as noted before there is.

1. There is no penalty for poor residential PF.
2. The fixed capacitance of this device could be an improvement or too much or not enough correction.
3. As noted by others the best energy saver for residential is CFL's and turning down or up the stat depending on the season and turning off the lights.
4. There is no savings.

its not so much the power factor, as the lower amp/wattage use. does this make any difference?

robnj772 · 05-01-2009, 09:06 PM

ANOTHER KVAR thread ???????????????????

nick · 05-01-2009, 09:47 PM

Well yes we have its part of the economic recovery plan in the good old usa today everyone is thinkin green !!
You see you pay to have it installed by a out of work electrician he comes in and changes the temp setting on your water heater next he puts in lower wattage bulbs ect ect you do save power ! and your helping out the working class trying to make a living by doing your part to save energy . take care think green turn down t stat and a lamp !

Now just come out and say it your selling these and your not sure of what your selling right or wrong ?

william1978 · 05-01-2009, 10:08 PM

Its a four letter word JUNK.

that's a big no

BuzzKill · 05-01-2009, 11:12 PM

dude, c'mon! I saw the "sham wow" guy hawking that stuff on late night tv! It MUST work!

redbeard43 · 05-02-2009, 12:53 AM

it only works with motors the best, reduces heat. google KVAR scam and see what you get. ill have to find my post I made about it a while back.. YES another thread but a newbie OP.

redbeard43 · 05-02-2009, 12:57 AM

AAAAAAAAAAhhhhhhhhhhaaa...i found it..here ya go it was under the thread "power saver"..

Ok its my turn.. I went into the supply house the other day and they had a dvd set up with some gadgets, so i am a man i had to look. They arent selling it but a salesman came in to set it up for all to see, its called a KVAR energy controller.

Its supposed to reduce electrical waste by electromagneticity and reduces the NON-productive current in the electrical system. It is supposed to increase euip. life by reducing heat around the motor and wiring caused by reactive current...blah blah blah...

here is a sight to check out

Or read crap here:
http://www.globalgreensavings.com/
Opinion of this crap, let me digress,

The electric meter does not register reactive current, only watts. The
KVAR Energy Controller is a capacitor that reduces I squared R line loss.
By improving the power factor of the electric distribution system or an
individual motor, the KVAR unit reduces excessive reactive current that
produces heat, heat is watts, and watts through the meter are reduced. It
is easy to demonstrate how a capacitor can slow down the electric meter
when it is installed on the load side of the electric company's cash
register.

Follow your instincts, search or try it yourself.

Here is an idea, raise your hand, close your fist, stick out you index finger and turn the switch off, save power....... tadaaaaaaaaa..

What worries me is he screen name is EMC. If he is Navy, he is giving the rest of us a bad name by even mentioning kvar scam.

redbeard43 · 05-02-2009, 10:54 AM

probably a salesman like the past hiding under a name or some original that has more than 1 screen name

nick · 05-02-2009, 05:35 PM

Well you can not sell one unit meaning one size fits all homes for power factor correction . Each home would need a study done on that home . what home owner would pay to do that ?

The kvar needed on each motor needs to be at that motor not down stream at the service outdoors !

Lets look inside a few capacitors one or two metal oxide varistors and a choke coil for back feeds online . a coil its a ripple filter for what ? we need ac not dc power in our home .

Question how come GE does not make these for single dwellings ?

What about your computer or all your electronics at the house do you really need a capacitor increasing you voltage at that outlet up to say 160 volts ? because when you add caps thats going to give ya more volts .

Lets look at a short or a appliance with a problem whats that extra voltage stored going to do ?

Does it effect a GFI meaning trip time or maybe burn out or limit some devices in your home meaning limit the warranty of its life span running at higher voltage ?

Best part is all your electronic power supplies will be hotter running as ther internal dc voltage regulators will need to disapate that extra dropped voltage of the correction caps now attached to your service . Take care be safe but dont take the bait !!!

Nick, thank you for explaining, that helps it make sense to me why this is not a great idea. Let me clear the air and say that i am not a salesman and do not believe in these. It sounds like a get rich quick type of thing to me. Greg, let me apologize to you for "making you look bad" by using my initials as my screen name, next time I'll try to be more creative. This was brought to me by someone I know and I said I would look into it. Thanks to all for your help.

Well we understand that its just there are some who come on and are trying to sell it to us folks and i do like to debate with them for fun ! We can say they kinda do work but its not much just pennys .
I will not go running out and purchase one but id like to test one in a controlled kinda load take it to the test bench !! You can only use energy wisely energy used is energy lost law of physics . EMC GEEZEE i dont know anything about electric stuff i was just helping out Greg with that Navy comment !!! Take care best to ya
