Big problem toconnect my houses to the PEA network

[pat7561]

I am looking for advices or/and  experiences about  this  maybe special situation :

 

-  2 houses , 2 blue books  (island) the building is 99.5% finish now.

-  I put  underground 250 meters cables 3+1 35mm to connect one house  to the PEA  network on the main road.

   PEA  told me that they change their price policy:

* price for 15A  is  26 000 B

*And for more power  you have to pay after study (6kbaths) a price  betwen 200 000 to 500 000 b just crasy and of  course ou of my budget.

I think that my needs of power could be more than 15 A  and less than 30 A because many of my appliances  are inverter  type ,TVs LED and 100% of my lighting are LED . i  have also pump for my swimming pool and several small electric heaters  for bassins in bathrooms.

My idea  is to add a second meter 15 A (at the name of my second  house) and connect thes two meters to my cable 3+1 35mm. Like that i can get my 30 A to be confortable  not spent a lot of money to pay for upgrade PEA meter and no add a new expansive cable).

To improve  the system i could be add a generator  to manage the peaks and also avoid the problems when PEA networl will  crashdown.

 

What do you think about that  and thank a lot for your advices ( about PEA policy and regulation and also technical ideas)because i  am not a  specialist and i worry.

 

Thank you in advance for your help

Best regards

Well, if you get the phasing wrong ... (cue the explosion). Yes, the event will be of an explosive nature possibly resulting in death or at least permanent blindness of the poor soul who hooks it up (and the annihilation of the meter).

 

It is highly unlikely that PEA will allow you to hook two meters to one cable.

 

I'm assuming that your "3+1" cable means you have a 3-phase supply. The "15A" meter is likely a 15/45 (45A max) meter, on 3-phase that's 45*220=9.9kW per phase = nigh on 30kW for two homes. How much oomph do you need?

 

What is your prospective load? Give us an idea of what you have connected (A/C and water heater sizes, number of rooms and the like).

I have a six bedroom house in Bangkok with normally 4 ac running at night and 3 20 CF refrigerators/washer/dryer/dishwasher/six bathrooms with electric water heaters/water pump and normally 8 people with 4/5 TV sets and several computers running on a normal single phase 15 amp service (these are rated to 45 amps - not 15 amps max).

Are you wired for a single or 3-phase supply??

 

As a quick and dirty guesstimate I would say a 3-phase 15/45 supply would do the trick.

 

What exactly are PEA prepared to provide?

 

[pat7561]

I think that PEA is  changing its policy  and wants that the new resorts and villas have to pay the upgrade of the electric network in this island. And when  you are asking for more than 15 A , officer answers you more than 200 000 thb.

 

i am wired for 3 phases supply .

[Crossy]

As I noted, if what you say you have is correct then a 3-phase 15/45 (15A) supply should (just) be adequate.

 

The 200k ++ quote is likely for your own transformer ($$$) if you intend expanding your consumption in future it may be wise to invest now, prices never go down.

Some of my investments always go down.  ;(  At first anyway.  Then sometimes I get lucky.

 

Sorry, I guess this is off topic.  Delete?

I've had power 14 years own poles,own cable 800 metres then as village grew 600 metres to home.

I have a couple of neighbours in between with shacks that have a toilet and have been given blue books and are now applying for power.

I have no problem as the closer its gets to my place the cable run will be shorter for me but probably offset by more end users with no bigger transformer.Also less chance of liability with less of my own poles on public road.

The funny part is there applying not through the pui yai ban with a list of names but to PEA direct and say the government has funds for village houses with temporary or no power for the amount of 75,000 per household or 5 power poles at 40 metres apart.

Anybody else heard of this?
