The Electricity Saving Thread

[vinj]

Around 11.6% at the least. As i said, i have to give it 2-3 months to establish an average for consistency since i have not finished an entire billing cycle/month with the new A/C in use yet.

thanks for your inputs sir. ang problem lang, decrease nga kw-hr mo pero ung rate ng kuryente natin pataas.

[brainmafia_310]

but ung pagtaas ng kuryente is just below 1% ng total electricity cost eh. Kaya panalo ka pa din.

Ang problema mo sir ung appliance ng kapitbahay mo. Sabihan mo na kasi mag upgrade na din sila para lalo ka makatipid. Hehehe

1% lang ba sir? baka you mean 10%.... haha, epal ka sir baka sa akin pa kumuha pambili ng upgrade appliances.

yes sir yung increase eh less than 1% lang ng total electricity cost per kwhr.

What are the pros and cons of using a primary metering vs multi metering?

Depende sa set up bro. Sa pagkakaintindi ko ha. Primary tpos may submeter? - and advantage is one bill simple pero kung multiple users ikaw gagawa ng billing every month, mas matipid sa electrical installation, mas madali lagyan ng back up power disadvantage nasa primary ang lahat ng losses na mahirap icompute may time na humabagsak power factor. Multimetering - disadvantage mahal electrical connection especially if you will use back up power. Advanyagr Ok ang power factor, bahala sila ni meralco magusap,. Yan muna boss. Dami pa eh.

Linawin ko lan na ung multi metering na tinutukoy nyo e every floor (or room) meron sariling meter (not sub meter).

Makakatipid ka kung ung negosyo mo at bahay mo ay iisa. Advisable talaga na hatiin mo ang metro. iba kasi ang rate ng commercial sa residential.

From what I know, primary metering is used mostly in big commercial (like malls) and industrial loads. In primary metering, the meter is at the service entrance before the transformers. So if the supply is 69 or 13.8kv, the consumer buys its own step down transformer to bring the voltage down to 480 or 220V. The meter reads everything including power factor losses, Cu and operating loss from the transformer. The consumer owns the transformer.

I'm not sure what you mean by multi metering.

If your application is a small commercial or apartment building. Then its best to have a individual meter for each slot billed to them directly by the power provider. Not sub-meter.

Sir, the reason I ask whether it is more feasible to do primary or secondary metering is because of the highlighted part. Will my opex be high since we will buying the transformer if we proceed with the primary metering? or will my electricity billing be much higher if we proceed with the secondary metering since meralco will provide the transformer and of course this will be charge to us in our monthly billing.

Sinaksak ko na naman yung extreme power saver ko. Baka sakali maging effective this time. 7k na naman ang binayaran ko last time.

Your initial cash out will be more if you buy transformer, than letting Meralco supply the transformer. Do not that even if Meralco owns the transformer, you may still have to pay them for it. They will compute the amount based on the cost of the transformer and wires needed for the project.

I'm not sure of your monthly billing will be lower with a primary meter. I am in a province not serviced by Meralco. Theoretically, it should be lower. But since Manila Water charges everything back to the consumer, how can we be sure that Meralco does not have the same practice. If you read your bill, there is system loss, missionary electrification and a whole lot of other stuff.

My view is, just get everything from Meralco. This way, you dont have to worry about maintenance. You also wont need to buy the transformer, wires and protective devices. And if the transformer blows or catches fire, Meralco will replace it for you. Also, the transformer losses will be part of the system loss. If you go with a primary meter, you may still be charged for system loss and your primary meter will register your transformer losses.

What's your business and how many KVA transformer do you need?

[brainmafia_310]

Retz, 1to1.5mw kaya ibigay ni meralco transformer for free (no step down needed) as long as susunod ka sa guidelines ng location ng transformer. Unless otherwise you will be constructing a high rise building with a load more thwn 2mw.again depende sa division of load mo pwedeng hindo ka na kumuha ng another stepdown transformer.Similarly, irelevant na kung ano gusto mo mangyari - depende sa design mo kung primary-secondary or sub or lahat direct metering (another design rule will be applied by meralco).

Imho kung commercial complex at required ka mag genset with 100% back up mag primary-sub meter ka mas matipid sa wiring ay simlple design ng transfer switches mo. Cons kukuha ka ng tao taga reading at taga bill at taga singil.

^^^ That is a very good point. Add'l step down transformer will mean add'l investment and costs. Malaki din ang transformer losses niyan.

Guys makas ba sa kuryente an shower heater 3500watts. Used 3x a day for say 15mins each? Nagtataka ako nungnagpakabit ako spiked ang bill ko by 3k...

the answer is both yes and no. have it checked by the supplier and dapat mag - oon lang siya kung may flow ng water which is the typical design nowadays.

yes - depende sa sarap ng pagligo mo at haba ng time na naka-on siya, at full power mas malakas pa siya sa typical room aircon
no - if installed correctly, you pay for what you need ika nga nila.

Thanks. Yup auto on lang siya pag ginagamit. Hind ko alam kun eto ang nagpalakas jumpingmy bill to 3k more or yung naiwan ng katulong na electric stove na on and off fpr more than 1hr. Ganun ba talaga kalakas?

Malamang yung electric stove yan especially if naka high. Meron kami heater and is being used daily pero di naman ganun kalakas sa kuryente

Bro, rough estimate lang ito - 3.5KW * 15*3/60 *P10/KW-Hr = P26.29 per day

Assuming you are using it 30 days in a month = P787.50 ang additional bill for that...

One hour sa electric stove,- assuming 2KW x 1 hour = 2KW-Hr * P10/KW-Hr = P20 lang.

Thanks for the info sa electrive stove brother. Did also the computations sa heater and dinoble ko na nga ang usage for conservativeness. Nagtataka nga ako bakit ang laki ng nadagdag. Nagdududa tuloy ako baka ginagamit ng katulong namin yung aircon sa room nila (naiwan ko pa kasi di ko pa nalilipat. Hehehe).
