⌛ Noreco Transformer Requirement

Has anyone had to pay Noreco to install an transformer to handle the load for their house? My builder has sufficient voltage, amps, or whatever the hell it is coming into our house. However, the aircon company owner, whom I respect, says because of the Noreco potential fluctuation in Bacong and other areas I should request a transformer be put up to support my load, at my cost.

 

Hi Pat. A. Transformers don't do much for fluctuations...the inductance of the windings will slow down spikes and dropouts a little...but only for a very brief period...ie milliseconds in most cases. B. Not sure where they want to put this transformer....but if it is past the meter...you'll be paying for the losses. Put your hand on any decent size transformer under load and you'll feel heat - perhaps a lot of heat. Losses thru transformers are typically 5 -30% depending on how good it is and how well it is suited to the application. What you may actually need is a power conditioner. Big box - had one in Saudi - weighed about 70 kilos....definitely does a decent job ironing out the power fluctuations....but eventually they will give up if your 220 vac becomes 150ish for example...There are limits to what they can regulate. .And they also have some power losses of their own (ie electricity consumption that you wind up paying for). And they are not cheap - but may be worth it if you run a lot of sensitive electronics. Hope that helps. My guess is that you can live on the electrical edge like most people.....replacing the odd casualty...

 

If you consider to install a transformer, just go to Polaris, they can give you all the requirements for Noreco.
It may take a while before Noreco will install and connect the transformer.

 

I, too, recommend a power conditioner (aka voltage regulator/stabilizer). We use a 10kva
unit, which isn't large enough to power everything in the house. To get around that, and to avoid the cost of a unit which would be big enough, we ran a couple of separate circuits from the regulator to those appliances most likely to be damaged by low voltage and/or fluctuations in current. Refrigerators, air conditioners, computers........ So far, it's worked very well for us. I would be happy to show you how we set it up, if you're interested.

 

Pat, aircon man is worried that line voltage from a communal transformer wouldn't have the power to run your system without problems. The cure for that is having your own personal x-former supplying your house only. That transformer would be supplied with power from the high voltage line.
Like mentioned before, Polaris will come over and set you right up.
Meter will be wired in after the transformer so you won't be paying for power loss in the transformation process.

 

This is all I get when I Google "transformers". I don't think Polaris or Noreco would install one though. :D

 

Polaris has renovated with an extended range of products, so you never know knowdafish

 

Thank you all for your inputs. As a result, and to steal quotes from another thread, I went from "don't know sh_t" to "no sh_t" status. I will now go for a Polaris/Noreco transformer solution. Always never ending surprises when putting up a new house here.

 

We recently installed our own transformer in Camanjac due to a very low voltage in the area. It was a personal decision because the voltage drops as low as 170v at night time and it scares us that it will break the appliances even using an AVR. Now the voltage output is between 210 to 230v depends on the time but it sure is a lot better.

the cost is P40k for the transformer alone which is a surplus versus P70k for a brand new. We bought it from Polaris. Initially we want to purchase the brand new one, but a close relative said, you won't know if Polaris will give you the surplus or the brand new even if you pay P70k. so we opted for the P40k.

 

???? What!

Ahem! princeton! ANYTHING new from Polaris is warranted and comes with the original paperwork. These people are not fly By Nites! Regardless of what close relatives say!
