nakikita ko sa SM and sa TV shopping... its suppose to lower your electricity even if you if you use the same appliances parin...
parang lower electricity usage daw...???

supposedly it lowers consumption by line conditioning and providing lesser current and/or volts than the required. dunno nga lang kung applicable satin mga ganyan, or kung talagang nakakapagpatipid ba. wala kc 2 months demo or money back to do study.

sir... power factor correction ang ginagawa nyan.... if it was well designed, it will lower electricity consumption.... pero pag di tama ang design it will add up to your electric bills :)

true, the device will try to raise the power factor close to 1, the ideal.
actually meralco offer this kind of scheme to heavy electric consumers like plants.

not sure if malaki matitipid mo dito...

power factor correction uses capacitors/inductors, big plants use these to lower their bills... malaki ang bawas nito for big plants....

i think dapat less than 0.8 yung power factor mo, kasi if more than 0.8 meralco would charge extra (may panalty), up to a certain point lang pwede umabot yung PF

wala naman kasing penalty ang powerfactor sa residential e.

kung pang industrial naman, masyadong maliit yan.

from wikipedia:

"The significance of power factor lies in the fact that utility companies supply customers with volt-amperes, but bill them for watts. Power factors below 1.0 require a utility to generate more than the minimum volt-amperes necessary to supply the real power (watts). This increases generation and transmission costs. Good power factor is considered to be greater than 0.85 or 85%. Utilities may charge additional costs to customers who have a power factor below some limit."

It just add up to your electric bill. I'm an electrical engineer and I can say that the device is some sort of capacitor load which just "corrects" your power factor.

First of all, residential consumers are billed based on kWhr consumption and not kW demand. Commercial and industrial consumers are billed based on kWhr consumption and kW demand. When you say POWER FACTOR, your dealing with KILOWATTS and not KILOWATTHOURS. kWhrs are electric energy while kW is power.
Voltage (230V) x Current (say 10Amps) = 2,300 Watts or 2.3kW.

2nd, capacitors also consumes electricity. It acts like a battery because it stores energy and it dissipates during the "discharging process."

Just for a thought...

This morning biglang nagamoy usok sa kitchen namin. Yun pala umuusok na yung Power Star na nabili namin noon sa Home TV Shopping. Buti na lang during daytime nangyari. Kung hindi baka nagkasunog pa sa amin.


I opened the device and guess kung anong laman ng "hi-tech" na device na ito?

'Yan talaga lang 'yan, the power factor correction lang 'yan. but for us residential consumers, we're not being billed based on kW but kWhrs so it doesn't do any good. It just adds up to our electricity because it's a capacitance load.

True Power = Real Power + Reactive Power; P = R + jQ

Reactive Power = maybe postive (capacitance) or negative (inductance)

When I saw that thing being sold sa SM, I even lectured this to them.

Basically, residential consumers will not realize the savings of these "power factor correcting" gadgets, commercial and industrial consumers do. How? 1st of all, if you're a non-industrial (NIS) or industrial (IS) customer, PF above 85% will give you savings in terms of your Meralco bill. Most industries rely mainly on motor loads and these loads require power factor correction since these equipment aren't 100% efficient! Even in their lighting needs, they uses ballasts for their flourescent lights, these also need further PF correction.

Totoo ba ito?

Dalawang klase alam ko, yung isa, plug sa outlet, then plug the appliance sa gadget (maximum of 2 appliances yata).

Yung pangalawa, plug to any outlet, ganun kasimple. Nakita ko sa isang internet shop ito, sabi nung shop owner, malaki daw binaba ng consumption niya.

I can't understand how it works, parang imposible.

Question, totoo ba ito?

Hello mga BNCers,

Sorry po pero di totoo lahat yan claims na nakakabwas ng kunsumo at bayad sa kuryente.

You cannot foil the electric meters reading your current consumption in your house by simply plugging these gadgets.

By basic electromotive force equation:
v=ir and current = voltage/ resistance
i = 220vac/ R (resistive force of conductors in your appliances, and house wirings) = x watts

cutting on current consumption can only be through:
- reducing electric appliance use and cutting on high power appliances (irons, electric ovens, freezers, big TVs, etc)
- using energy efficient electric devices (energey saving /EL lights. EER appliances etc.)
- using superconducting wires in your houses and appliances and ofcourse on the power distribution lines less pilferage (but this is ofcourse far from being real and practical)
- just dont use electricity period

in short: these gadgets are all but a big fat con. this is why its not being promoted by the government or any educational instiution in the country for that matter even in the midst of energy crisis.

cheers and sorry to dissapoint you.

doc: medyo malabo yata sabi sa yo ng taga handyman. kase sa resibo nila at company regulations, 7-days lang simula ng pagkabili mo ng kahit aanong item nila pwede mo isoli at papalitan yung item.

so 7days is not enough to test that gadget unless meralco gives you your bill in a weeks time for a week's consumption.

yung bayaw ko bumili ng ganitong gadget sa ACE, im just waiting for their bill to arrive and tingnan ko kung drastic nga ang baba ng bill nila. Pero still the sure way to cut electricity is to yurn off unwanted lights.. turn off TV not on standby mode.... and if kaya pati mga night light sa labas ng bahay, kung katapat niyo naman ang meralco lamp post.

Depends I think on the meter used. Power for resistive loads (heater, incandescent, etc...) are not affected since there are no inductive load to correct. Capacitor banks in inductrial facilities are switched in when the inductive load which lowers the power factor increases to the point of gettive penalized by Meralco, hence power factor correction.

Adding the capacitor reduces the inductive load (fans, aircon, compressor) assuming the capacitance is large enough. If the meter measures both real and imaginary (using electrical engineering terms) which is not the case for residential I think, then sayang lang pera mo.

Still, the best way is to check if the speed of rotation of your meter really slows down. I think hindi pang residential yung sa mga demo.

The gadget is just a power factor corrector.

Tama si poops. Sa mga malaking kumpanya na maraming mga makina, pati yata reactive power ay sinisingil.

Eto kung matiyaga kayo magbasa (from Wikipedia):

AC power flow has the three components: real power (P), measured in watts (W); apparent power (S), measured in volt-amperes (VA); and reactive power (Q), measured in reactive volt-amperes (VAr).

The power factor is defined as:

P / Q

In the case of a perfectly sinusoidal waveform, P, Q and S can be expressed as vectors that form a vector triangle such that:

S2 = P2 + Q2 (squared po yan :))

If w is the phase angle between the current and voltage, then the power factor is equal to |cos w|, and:

P = S * |cos w|

Since the units are consistent, the power factor is by definition a dimensionless number between 0 and 1. When power factor is equal to 0, the energy flow is entirely reactive, and stored energy in the load returns to the source on each cycle. When the power factor is 1, all the energy supplied by the source is consumed by the load. Power factors are usually stated as "leading" or "lagging" to show the sign of the phase angle, where leading indicates a negative sign.

If a purely resistive load is connected to a power supply, current and voltage will change polarity in step, the power factor will be unity (1), and the electrical energy flows in a single direction across the network in each cycle. Inductive loads such as transformers and motors (any type of wound coil) consume reactive power with current waveform lagging the voltage. Capacitive loads such as capacitor banks or buried cable generate reactive power with current phase leading the voltage. Both types of loads will absorb energy during part of the AC cycle, which is stored in the device's magnetic or electric field, only to return this energy back to the source during the rest of the cycle.

For example, to get 1 kW of real power, if the power factor is unity, 1 kVA of apparent power needs to be transferred (1 kW ÷ 1 = 1 kVA). At low values of power factor, more apparent power needs to be transferred to get the same real power. To get 1 kW of real power at 0.2 power factor, 5 kVA of apparent power needs to be transferred (1 kW ÷ 0.2 = 5 kVA). This apparent power must be produced and transmitted to the load in the conventional fashion, and is subject to the usual distributed losses in the production and transmission processes.

It is often possible to adjust the power factor of a system to very near unity. This practice is known as power factor correction and is achieved by switching in or out banks of inductors or capacitors. For example the inductive effect of motor loads may be offset by locally connected capacitors. When reactive elements supply or absorb reactive power near the point of reactive loading, the apparent power draw as seen by the source is reduced and efficiency is increased. The reactive elements can create voltage fluctuations and harmonic noise during connection and disconnection procedures, and they will supply or sink reactive power regardless of whether there is a corresponding load operating nearby, increasing the system's no-load losses. In a worst case, reactive elements can interact with the system and with each other to create resonant conditions, resulting in system instability and severe overvoltage fluctuations. As such, reactive elements cannot simply be applied at will, and power factor correction is normally subject to engineering analysis.

tama po, you can correct the APPARENT power eaten by inductive loads, para mapalapit syasa TRUE power na kinakain nang resistive loads...

if you would check the flourecent lamps set from philips may kasama capacitor... para yun ma alis ang apparent power na kinakain nang ballast.

pero kung gusto talaga makatipid nang kuryente, i-off ang di ginagamit na appliance :)

Store warranty is 7 days. You can still return the item if you insist for it. Such acceptance of returned items depends on the "consignor/promodiser" or store manager. Especially kung may warranty yun item.

We also have this gadget at home. Parang the same pa din dahil bagong palit ang electric meter namin... :(

tatlong pinakamadling solusyon sa pagbaba ng kunsumo at bayad sa kuryente.

1 - off mo mga electric appliances and lights mo sa bahay mo
2 - jumper! - pero baka mahuli ka!
3 - mag patakbo ka ng generator o gumamit ng kombinasyon ng mas renewable na power source - solar, biogas, etc.

iwasan ang sunog, wag magtiwala sa mga walang basehan na electric gadgets!

Bumili kami nito when it went on sale before for 1,499. Based sa usage sa meralco billing, bumaba ng konti yun graph starting sa month na ginamit namin itong unit. BUT it is hard to determine if yung pagbaba ng graph is based solely sa powersaver or sa actual usage lang namin ng kuryente.

no electric gadget can save your electric consumption! wag po kayo mag paloko sa mga manloloko!

your electric meter in front of your house has an electromotive induced dial plate.. it turns when electromotive force or electron particles move through the meter going to your appliance or anything that has lower potential difference - this includes a ground (if its short-circuited). -- there is no electronic or electrical gadget that can stop this meter unless you bypass it (with a jumper) or stop using any electric load (electric and electronic appliances or anything that has a motor or heating element)... putting a magnet near the meter will also not work because the disk is made of aluminum alloy which is paramagnetic.

one thing (from an engineering stand point) that can save electricity is using right sized wires, breakers, and proper electric branch layout design and implementation... this will cost higher at the onset but is safe and economical to run long term... - this is what i have in my own house and other house i've helped build.

There is a device that can actually make this disc run in reverse. :P

It is illegal and I am not sharing. The best way to save on electricity is to use it efficiently. That's it. Turning off the ref in a certain time frame at night can spell the difference in your electric bill. But of course, the seal of the ref must be tight and you have no member in the house that is a ref looter at night. :D

@wildswan: yes, there is a way to get the meter to run in reverse... but i was not referring to it running in reverse. what i was saying is something to slow it down or stop it even if the electric load is passing through it. if i would steal electricity, why put something to reverse the meter turn.. why not just put a jumper... its much easier, less costly and there's nothing secret about it. - ofcourse - its also illegal.

making it run in reverse even if you dont share the info will not work long term. meralco will see this eventually and they will do a historical assessment and averaging of your electric consumption. then closely monitor your usage and if you get caught. then your line will be cut and you will need to settle lump sum amount depending on their computation of how many years they think you have been driving your meter backwards. then if you paly and reconnect your electric line... they will replace your old analog meter with a new digital meter that does not have the disc... so useless na rin yung gadget mo..

as for your suggestion to turn off the refrigerator... well, i also beg to disagree - sorry... :) why? because this only is valid if you use old refrigerators - those that were manufactured before year 2000 and if you have more than one ref in the house.. (ie. several small refs)... i say this because the newer refs and freezers have higher EER for their compressors and are also designed with optimal freeze or no-freeze cooling using internal cpu controlled fans... in fact, the ref i use in my house is a whirlpool (double door 18cu-ft if im not mistaken) that consumes runs 'no-frost' with a graco compressor and eats about 145watts when running at full power (fast freeze) for making quick ice (in 10mins or so). the cost of running this ref in a month is only 300 pesos more or less... so what you are suggesting is partly true for old refs but not always true for newer bigger refs. and lastly... you can only do what you suggest if you are the only one in the house or if you have no kids in the house that eats round the clock...

if you really wanted to save money by lowering electric load power consumption... i recommend you take the ff considerations.

- turn off all lights and appliances (unplug) when not in use
- schedule ironing 1-2 times per week only
- schedule washing machine 2-3 times per week only
- run airconditioner on a timer to turn off 30mins or so before your alarm clock rings on your preferred wakeup time, better if you have an automatic fan that runs when the AC turns off..
- ensure that you buy only right sized airconditioners and electric fans for the room you intend to use such in... improperly sized A/Cs will result to cooling inefficiencies and will get you higher electric consumption...
- if you have a new house you are building, put more windows and pass though ceiling natural day illumination (this helps cut cost of using lights during the day around your house)
- boil water using LPG or coal instead of electric
- use LPG fired oven instead of electric
- use LPG water heater if you can or combine this with solar water heater (LPG at night, solar by day - cuts your electric bill for sure)
- use modular water heaters instead of single tank centralized setup (centralized has higher thermal loss than multi-point water heaters)
- turn off light in your garage if the frontage of your house is lit at night by nearby lamp post lighting
- reduce the runtime of inductive loads (motors) in your house - if you have a pump - make sure that its rated properly and married to a correctly sized pressure tank
- if you can - make sure that when you build you house that you use proper sized conductors (wires) and proper electric wiring load schedule (branche circuits), because incorrectly sized and loaded electric wiring in your house can result to inefficient transmission of electricity which may cause wires to overheat or burn or electricity to arc on your circuit breakers... and worse - may start a fire...

imhotep, yes, I am aware about the stoping of the meter.... the gadget that can actually make the meter run in reverse can be use to stop the meter by adjusting it just like you are adjusting a volume meter. In that effect, it can also be used to slow down. AS it is illegal, I will not go into the detail. I have it in my collection of "once worked" experiments. Thanks to my idol Physics teacher at MIT...

That's NOT secret. Meralco already knew that kaya Meralco is already using line to line to eliminate illegal loop connections brought about by line to ground, like in some provincial areas.

Sooner or later, you will be caught and you will be charged in violation of RA 7832 or popularly known as the “Anti-Pilferage of Electricity and Theft of Electric Transmission lines/Materials Act of 1994”.

applicable rin ba to sa mga digital meters?
Naku, eh bukod sa delikado at baka makuryente o masunugan po kayo, malamang sa mga lumang-luma na metro lang gumagana yun. Sigurong matagal na ring alam ng Meralco ang kalikot technique na yan. :D

Kailangan siguro ay ibayong vigilance sa pag-limita ng gamit at pagpatay sa mga appliances kung di naman kailangan. Sobrang taken for granted na kasi natin ang pag-iwan sa mga ilaw, TV, radyo, computer, electric fan, atbp. ng naka-on kahit wala namang taong makikinabang dito. Baka kung minsan ay umaabot ng mahigit 20% ng ating total electrical consumption ang nasasayang lamang dahil sa pagiging maaksaya.

Aba, kung 5K for example ang Meralco bill natin, baka 1K rin yun! :D

It's true and some Meralco men ang gumagawa nyan BUT it's very risky. Meralco will pull out your meter if they suspect na may kalokohan and have it check sa laboratory nila. If you get caught sisingilin ka consumption ng load ng mga installed appliances mo sa bahay (kahit ginagamit or hindi). I know someone who was charged 300k+ nung nahuli na tampered ang meter nya.

Maski Manila Water pwede din. Yung nagakabit ng metro ko nung nasira offered to do it for me for a price but I declined. Mahirap na.

So yung mga binebenta sa malls na power-saving device daw, during their demo, bumabagal yung kuntador? Pano nila ginagawa yun?

^ kasi po, induction motor at ballast based na ilaw po ginagamit nilang pang demo. Subukan nila yung incandescent bulb or plantsa... di gagana yun. Kasi nga po, power factor po ang kinokorect nung gadget. At iton power factor correction ay applicable lang sa mga electic na Induction ang base principle to work.

^I See. Pa-try ko nga sa kanila yung plantsa at incandescent bulb. Ano kayang reaksyon nila?! Tapos maraming nag-mimiron. He he he... pahiya sila.

Padagdag po, dalawang klase kasi ang electrical load natin sa bahay, yung resistive at inductive loads. Yung power factore correction, usefull lang sa inductive loads like motorized loads. Now, di lahat ng motorized load eh inductive... gaya ng hair blower/dryer. Resistive ito kasi it doesn't use AC current. This device converts the AC to DC and brings the voltage down to 12V, the operating voltage of the DC motor. Resistive naman yung mga head generators like plantsa, oven toaster etc.
