Kuryente !

[ReDHeaD]

totoo ba yun na pag 110v volts lahat appliance mo mas matipid sa kuryente?

[robbietan]

no sir, current will go up in proportion to the decrease in voltage. an electric oven consuming 500 watts will do that from eithr a 110 volt or 220 volt supply

bos boomouse,

 

you are most welcome ! this is what the thread is for.

 

methanx also to the other contributors

[robbietan]

looks like there is a lot of people still being bombarded by vendors of 'energy savings devices'. I have found a useful article from an old issue of a newsletter. those devices, methinks, are on page three

 

happy reading

I am a registered electrical engineer myself but I must admit that i admire robbietan for having all the correct answers to the questions. Grabe, galing mo bro... Maski ako magpopost din ng questions to you when the need arises hehe... Thanks to guys like you bro... :thumbsupsmiley:

no problem bos JT, member ka ba ng IIEE? tayo-tayo din ang magtutulungan sa mga problema ng profession natin

Unbundling is simply the identification of the individual charges, whether generation charges or

transmission charges or government charges. Unbundling was initiated in May 30, 2003 as prescribed by the Energy Regulatory Commission (ERC), and was implemented immediately, beginning with June 2003 billing cycle.

 

to better understand your bill (from meralco, that is):

 

Generation charge - its the price of power from napocor and other IPPs where meralco source their power needs

 

transmission charge - wheeling charges from transco

 

system loss charge - price of power lost from technical (transformer losses, line losses, etc)

and non technical (pilferage, etc). meralco can only charge a max of 9.5% for this. this is the total power delivered to meralco from napocor and IPPs minus actual power delivered by meralco to their customers.

 

distribution charge - this is meralco's rates

 

lifeline subsidies - lower rates for those consuming less than 100 kWHrs per month

 

govt taxes - includes EVAT and franchise tax. some cities (like pasig) dont charge the franchise tax.

 

universal charges - flat charges to all customers of the electric utility

 

missionary - to help finance electric power to 'poor regions' in the country, set by the ERC

environmental - helps finance the environmental projects of napocor like watersheds, etc.

Bro Robbietan, where ka ba connected na company? you have an accurate way of explaining the technicalities.

 

In the 80's theres a pamphlet which we can get from NPC entitled "RULE ON THE SALE OF ENERGY" . Is this still available in NPC? we are constructing an ethanol plant in Bukidnon and Isabela. My copy when i used to work in the mining sector is old.. the group that is in charge for the design and construction is asking for my assistance in the contract negotiation with the rural cooperative which we planned to sell the excess power.. The problem is, im the only one who has a background on this and im in japan right now..thats why im asking if you have an idea of any technical paper of NPC similar to the above which we can use as basis for the technical negotiantions..thx

I am making this very late post to thank you all for your inputs on what to do with the electricals during my home rebuild. Your insight proved to be very helpful and while it drove my architect and master electrician crazy, I am very happy with the result and aboslutely do not feel that I have been made to overspend by my contractor. He thinks I did this on my own. Overkill daw. Para daw nag wiring sila ng data center. Eh ano pa nga ba…

 

Just to let you guys know how it turned out:

 

You were right, Avesco still sells ABB circuit breakers so I went ABB all the way. I have a 100 amp ABB Tmax breaker for the mains and ABB S2 miniature circuit breakers under that as well as ABB F200 residual current circuit breakers for the kitchen, den, and my computer room.

 

Everything is on 3-wire stranded with Clipsal fixtures. The breakers are installed in the kitchen housed in an ABB molded breaker box with the DIN rails in full view. I do not like hidden breaker boxes because I want to see their status at a glance. We then connected an ABB ATS010 automatic transfer switch to this which handles starting, stopping and switching of the 25KVA Denyo genset outside.

 

I have a 3 meter, 10 mm diameter copper bar buried under the house to serve as the main grounding bar. We decided to go with rigid metal electric conduits with liquid resistant fittings. For the 110vac supply, I have a 10kva unregulated stepdown in the kitchen and a 5kva Comfac data grade AVR for the den and the computers. The Comfac supplys a different circuit of COs all around the house for computers and lcd TV only.

 

This installation forced me to scrimp on the other parts of the house but I am happy with the outcome. At least sigurado ako na kung masusunog bahay ko hindi manggagaling sa wiring. If you guys did not confirm my plans, I would have listened to my contractor and would still be wondering if my wiring was just "pwede na" instead of being to specifications.

 

Thanks again guys.

 

No problem. im glad that my comments have helped you decide on what to specify for your house. It was also a good choice that you use metal conduits vs PVC ,because metal conduits is good specially in ceiling installations. im almost finishing the oil refinery design for venezuela and will be coming back in our alabang office by sept..PM me if you need further assistance.

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.

 

Correct and well explained. Sir Biromn and tawag dun ay power factor correction. Its a ENERCON and system improvement installation. You need to evaluate the present power factor, calcute the size of the capacitor bank required to adjust your power factor to a level that you will get rid of the penalties for low PF and get a bonus for high PF. Devide the total amount of the installation by the savings and you will get the total payback period of the project.

[dominoneedsu]

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.

 

Sorry that i havent read this section for a while..i went to venezuela and texas kasi...if you still need some advice heres my email and YM crl_007@yahoo.com

hindi ko sir sigurado ung sa NPC but with EPIRA today, it would be better to contact a licensed RES (retail energy supplier) in your area. the function of the RES is to market, sell, agregate electric power. Licensed RES suppliers, to date, are:

 

TeaM (Philippines) Energy Corp. (TPEC)

Trans-Asia Oil and Energy Development Corp.,

First Cabanatuan Ventures Corp.,

Aboitiz Energy Solutions Inc.,

First Gen Energy Solutions Inc.,

Angeles Power Inc.,

iN2Power Inc.

GNPower Ltd. Co.

 

good luck, sir.

Salamat din sa info..i will tell them about these

[rc36]

mtc brods, pls give advice to me. all things being equal, which mor economical to use nowadays electric cooking appliances or using LPG. pls PM me. tnx
