Kuryente !

[robbietan]

dudes question lang po...

 

kasi am really quite confused sa taas ng electric bill namin... we dont use aircon and microwave... hiwalay ang kuntador namin para sa 1st floor at 2nd floor... what is running sa 1st floor is ref and 2 electric fans and 21" tv and computer.... yung tv, computer and electric fans usually open maximum ng 4 hours a day lang... sa 2nd floor 2 tv, 4 electric fans, computer... tv electric fans and computer open mga 6 to 8 hours a day...

 

ang pinagtataka ko, ang total electric bill namin is mga 5,400++... mga 2,800 sa baba tapos yung rest sa taas na... i asked mga friends ko who have almost the same set up, ang nakakagulat, some of them have lower electric bills, yung iba gumagamit pa ng aircon!!!

 

any help or suggestions will be greatly appreciated... tnx

 

p.s. pina check na namin sa electrician kung may short or something,wala naman na detect... pinatay na din namin sa master switch at si naman umiikot ang kuntador...

 

most probably you have a grounded conductor somewhere. a better test is to unplug ALL your appliances and see if the meter still runs. if it does, chances are you have a grounded conductor somewhere.

if you have a 110v supply, that is probably causing the irregular readings.

if you have an issue with the meter, you can file a complaint with meralco and they will pull out your meter to check it.

Hi,

To answer some of your questions:

 

 

3. Actually, matagal na yan three-wire connection. The problem is we SELDOM practice it. It's in the Philippine Electrical Code. Sa house nga dapat may nakabaon na bare copper cable around the house e. But due to the high price of such conductor, seldom na may maglagay nun. Kaya sa tubo ng tubig nakakabit ang grounding.

 

4. You will have to use two cicuits or set of CO's for that. If you want it, talk to to a registered Master Electrician for that.

 

3. beware that the 3rd wire is grounding, not to be used in powering an appliance

 

4. for a 110v system, you have to put up a transformer yourself since meralco (I assume meralco is serving you) does not provide 110V service. however, a transformer is additional load and I would like to advise you to calculate your loads carefully as to not to oversize/undersize your transformer

kulisha - if you feel that the meters are running fast, as a consumer, you have the right to question its accuracy. just go to the meralco (I assume its meralco) nearest you and file a complaint. the guys there will bring it to a testing facility to have it calibrated. meters are supposed to be at least 98% accurate, digital or not. meralco is responsible for meter accuracy, with the erc acting as control.

 

thanks robbie. would you know the procedure to file a complaint? tia

Ang alam ko is to bring your latest bill (since nadoon na rin ang history ng consumption mo) and a letter requesting for a meter calibration check.

 

good reasons would be

a) I have no new appliances yet my consumption rose

I unplugged all my appliances and the meter is still running

etc

 

meralco (maybe) will send someone to check on your electrical system first, before they pull out your meter.

heres my general contributions:

 

1) To those who would like to renovate the house and do the rewiring works. The best advice I can give you, is get the services of a qualified electrical engineer. So that he will be able to evaluate your needs and design a safe and reliable system for you that conforms with the provisions of the national electrical code. The problem in our country is we allow achitect to design the electrical system as well. This is not a good practice, no matter how experienced he is there are things that only the electrical engineer knows. So get the services of a qualified engineer during the design and actual supervision of the house wiring.

 

2) GROUNDING: There are two types of grounding or earthing. The first one is system grounding. The other is equipment grounding. System grounding is used by electric cooperative. wherein one line is hot line connected to the phase and the other is grounded in multiple points. MERALCO uses the line to line system, meaning the power supply is coming from 2 phases of electric power. Now for uses. in a 3 wire system for Meralco..the two wires are phase wires, the third wire which is colored GREEN or Yellow green is the EQUIPMENT GROUNDING. If you can afford, during the construction of your house, you must have a grounding system around your house, to be designed by a qualified engr. this grounding system is where the grounding points of your house wiring and your appliances will be be connected. The advantage of this system is safety, specially for appliances that is prone to become wet, ie refrigerator, washing machine ang electric range. The principle behind is that when there is a power leakage, it will safely be discharged to the ground. When you dont have a good grounding system, you will get mild or severe electric shock when you touch the handle of old refs, washing machine and electric range.

 

3) ESD or energy saving devices. These are usually power factor correcting devices only. When you use appliances that is inductive..meaning there are coils of wire in it..motors, etc. your power factor is lagging by an angle..that we will not elaborate. I would not advice buying this product specially if its expensive. Instead of buying ESD's try to practice the following energy saving practice.

3.1) Appliances that produces heat consumes more power that rotating appliances. So when you iron your clothes..do it by bulk.

3.2) When using Airconditioning units..use the timer so that the compressor shuts down when you are already asleep. Then your unit is not equipped with

timers, buy a good timer. to check the capacity of the timer, check how many ampere it is rated and compare it with the ampere consumption of your

AC unit. Note that the rating of the plug timer must be greater by at least 25% than your load.

 

4) 220 versus 110V? no big deal advantage. If you plan to use a dual voltage 220 and 110 volt system in your house. be sure to use a different type of plug for

the 110 appliances to avoid plugging it to the 220v system.

 

5) For the sake of non electrical people..power consumption that you pay to meralco is in kwhrs. meaning 1000watts operated for 1 hr...1000 thus the word 1

kilowatt for 1 hr. So it doesnt matter what appliance you use..when the sum is 1000 watts used for 1 hr..you pay the rates..or it could also be 100watts used

for 10hrs.

 

6) Why faulty wiring produces fire? faulty wiring has many forms. but the usuall method is octopus connection. Note that commercial extention outlets uses small wires and so many appliances is plug to this extention, chances are these lines become overloaded, heats up, produces spark and when the kindling temperature is reached ignition is created and fire starts. Pls donot stock highly combustible liquids near a power outlet. When your light does not light up at night..if its fluorescent type, check the voltage, because maybe it is low. or check the switch, change if is deffective. ABB circuit breakers are still available on the market. try to check with AVESCO marketing or other big electrical hardwares..or thru the internet.

 

if you have problems with your electrical system..PM me and if im in the Phil..(im in japan now) i will check your system free of charge..ibili lang ninyo ako ng snack na barbecue na saging ok na. jk.

 

i hope this helps.. to the room owner..its just a little contribution..wla magawa dito sa japan eh...

mas mahal b consumption ng kuryente pag gabi compared tuwing morning?

Dual meaning ang tanong mo..

 

Kung sa billing ng kuryente ang ibig mo sabihin..sagot dyan ay hinde. pareho lang. or if you mean na mas malakas ba ang consumption ng kuryente sa gabi compared sa umaga...ang sagot dyan ay oo at hinde. oo malakas sa gabi kasi madagdagan ng ilaw. hinde nman kasi..ung ginagawa mo na gamit ay kuryente sa araw ay di mo nman ginagamit sa gabi.. i mean depende sa pag gamit ninyo ng appliances at ilaw. Pero generally ma gabi o ma araw man ang isang appliances na 1000watts (plantsa halimbawa) pag ginamit mo ng isang oras...its one kwhr bill gabi or araw mo siya gamitin...kasi ang binabayan mo nga is per kilowatt hour..

mayroong 'time of use' program ang napocor where electricity price is lower per kWhr in the evenings than in the mornings.

 

however, this scheme is open to large industrial and commercial users. altho I believe that meralco has openend the scheme to residential users having a monthly consumption of 2,000 kWhrs per month.

 

If your consumption is equal or above 2,000 kWHrs a month, you can go to the nearest meralco branch and apply for this scheme. to make this scheme work, all kuryente intensive activities be scheduled for night (like ironing and laundry) as prices are lower than in the daytime.

[tommy69]

They are offering it to residensial cust. that use at least 10,000 pesos a month. The only problem is that if you load usage is balanced ( the usage of the daytime and nighttime KWH) is more or less the same, there is not that large a savings resulting in it. Moreover, there is a chance that you might have to pay more!

Unless you will start shifting usage at night.

OY CAll ako barbecue lang pala eh. heheheheh. Pm me naman dude.. I have lots of questions. pm mo na din ang yahoo messenger mo.

 

Dude how come yung isang electrical engineer na factory manager nang isang big garments factory installed one of those ESD but one that he designed and built himself he told me the parts lang inabot na nang 100 thou plus basically big capacitor lang daw.within a few months bawi na. thanks pare.

With Sir Dominoneedsu's permission, I would like to reply to Sir Biromn.

 

Sir, that's because Meralco charges three-phase customers differently from single phase (mostly residential) clients.

 

Those that use single phase meters are charged based on their Kwhr consumption only. But it becomes more complicated for three phase customers. Three phase meters monitor kwhr consumption differently, and Meralco has a more complicated method for computing the total bill.

 

To put it simply, Meralco does not monitor reactive power for single phase customers. The capacitor bank ESD works to correct the reactive power consumption, which 3-phase customers pay for. Installing one on a sigle phase system here in the Philippines will not have a significant effect on the total bill that's to be paid for.

 

So why are they advertising it on TV? Please observe that the advertisements came from Taiwan. They probably charge single phase customers in Taiwan for reactive power consumption, so it works for them there. But in the RP, it will not have the same effect.

 

Hope this helps.
