I m not sure if such device exists or not... Some people in my locality are talking about it.

Thanks to power rate hike...

Please share your views on this.
 
I don't know but my father bought such useless device from a door to door salesman. I threw it away. Useless 300 Rs device.
Don't fall for that.

Even i used to think the same until I met a very close relative.. She is using this device since last 6 years ..

I will try to get more details but she is 59 and stays little far.. I will try googling such devices ...[DOUBLEPOST=1372669804][/DOUBLEPOST]This may not be the device we are referring here in this thread..
but still worth a watch..

Cannot see the video in office but the one at my home was a red block, in height of Note 2 and a 2 pin behind it that goes in plug point. I feel this is useless like those ultrasound mosquito repellent.
 
Well to tell you frankly no device can actually save you power. If your equipment consumes X units per hours, it will consume X units in that hour no matter what.

However, what you can control is what we call power factors and impulses/fluctuations. Basically these devices have capacitance in-built into them so that they can filter some "electrical spikes" that might be caused at certain instances during usage like turning on ACs, TVs, Fridge etc.

Usually you do get a very healthy set off for improving your power factor in industries (Power factor is basically the amount of electricity that you take viz-a-viz the amount that is actually utilized). For residential areas the savings may vary from 2-5% at max depending on the type of loads in your house. These devices were very popular in Delhi where every household used to have their own booster pump .

Rest you be the judge ;)
 
there are so many things few electricians claim, around 2007 offered us a magnet that slows down the meter counter !! o_O
 
Normally motors' power factor tend to fall below 1 . Examples could be washing machines, refrigerator compressor or water pump motors.

So if the appliance advertised power is 100W then it will consume more than 100W due to power factor. Look up apparent power.

Industrial electricity meters have large capacitors installed so power waste is minimised. I'm not sure about the legality of such installation.

As far as I can understand this device is a passive power factor corrector or simply a capacitor.

Computer SMPS contain active power factor correction.
 
well there is no such product or the electric company themselves would give you such a product, because even if there is a 1% saving for reach household then they save a lot of money as it reduces transmission costs and all other associated costs.

Only way you could save power is if you are having very high voltage in your area. Say if you have 230-240 there is no savings but say if you get constantly around 260-270 or above yes you can save some electricity bill by installing a servo stabilizer. Each unit is calculated based on volts X amps. Now if you get around 230 and if say your AC consumes 7 amps the your units per hour would be 1610 watts or 1.6 units. Now say if you are getting power at 260 v then the same AC would consume 1820 or 1.8 units. Now if you install a servo stabilizer then it would regulate the power to 230/240 v as decided. Once you do that, the savings wont be .2 units per hour but say might be around .1 unit per hour as there is some power used up by the stabilizer. This is for each equipment. So you need to calculate how much you actually consume.

Yeah the idea we can suggest are better than the useless products that don't work.
Some things i follow...

1. Don't turn off the TV only with remote if you know you are not going to start it for a long time. Turn it off from main switch.
2. Most Microwaves have a clock display full time when not in operation. This clock is sort of redundant so turn off the microwave switch completely and use only when necessary and actually using it.
3. If you don't have a stockpile of clothes to wash, use the washing machine once every 2 days or so, more time between usages if possible. As it is, the machine is going to go through all cycles irrespective of the amount of clothes (in most cases).
4. If you are a deep sleep person, then set the AC to shut off after few hours in night rather than keeping it ON entire night. Fan on 1 or 2 along with AC also helps, especially after AC is shutoff in middle of night.

In many places instead of 230V AC it shoots up to 250+V and in such scenarios these devices can help a bit.

I recall an IC earlier on the forums. It was available from few TE sellers. .

For Rs.1600 on ebay

Since Amazon is shipping free on order over $125 you can start you own IC

Just checked on amazon.com Quotation before taxes. Notice that Indian plugs won't fit...

Just to add - a Kill-a-watt is only for measuring power consumption.

Plus it says its designed for 115V supply, not 230V. Will probably smoke the kill-a-watts electronics if its not geared for both voltages.

If this were true, all the low voltage areas would be saving power. But its not exactly. Simple devices like filament bulbs, fans, heaters would obviously burn more power with higher voltages, but they would also produce more light, spin faster, or heat water faster proportionately. I'm not sure if conventional ACs have no voltage regulation - inverter ACs have tons of power electronics - but if they do, the current draw would drop proportionally to the rise in voltage. Power has to go somewhere, any decent appliance will either use it or regulate it, not dump excess power.

When high voltages do come the bulbs like incandescent ones glow brighter( CFL/LED bulbs will glow the same but can go kaput if voltages go beyond its operating range).
Fans spin faster at high voltages but it will consume the same amount of amperes but the total power is now more so if the Electricity meter is calculating only the amps drawn then there will be no change in your bill but if it calculates the total power drawn which is (volts x amperes = in kilo watt power) then there will be a higher electricty bill.

Devices which have SMPS usally are more efficient at higher voltages but the voltages should be within its normal tolerance voltage range.

But you can use a regulator to turn down fan speeds and drop power consumption. There isn't any power 'loss' because of the higher voltages.

You can put it a lower the setting which will lower the fan speed,but when at the same setting, at higher voltages the fan will spin faster.
