voltage optimization

What is power perfector?

250v? whats country?

what is vsd?

if you hope to regulate voltage, we can offer you large power 3phase regulator at 2mS response.

I am referring to voltage regulators,the idea is to drop the voltage to around 230v which is nearer the european standard.We started looking into this as we have some machines from germany with some sensitive electronics (profibus communications from plc to drive board)which kept blowing.Although the problem was with the 24v power supply we started looking at supply voltage which was 250v single phase 433v three phase.The company already has power factor correction so would voltage regulation equipment save money?They have been quoted 50 grand with a five year pay back.Is this realistic and has anyone else installed this equipment?

The country is uk and vsd is variable speed drives

thanks

250V is awfully high for a supply voltage for equipment from England and Germany, it's no wonder that you are having some problems (blown any metal oxide varistor protectors on the 230V equipment have we).

Switching to a lower voltage tap on the transformer would reduce the voltage from 250V down to about 244V (but that still doesn't take into account the transformer voltage sag due to load, or the voltage variation due to natural voltage tolerance at the main supply 11kV). 244V is closer to 230V for German equipment and 230/240V for English equipment.

Before you spend the money for an expensive voltage reduction system (250V to 230V) you should check the voltage tolerances of the equipment you already have. Most of the equipment should run fine once the transformer tap is changed dropping the supply voltage 2.5% (Don't forget to take in to account the worst-case voltage variation on the 11kV supply). For the equipment whose voltage tolerance is a little too close to the operating voltage, consider a simple step-down transformer instead (which will likely be much cheaper, even if you have to get a transformer manufacturer to make them for you (which is a common and fairly inexpensive process)).

Remember, there is no economic point to conditioning (or power quality filtering) the entire factory if your problem is that selected machines are effected by the voltage tolerance issue (causing malfunction or damage).

you would answer these questions.

Do you hope to transfer 433v to 380v? (singal phase is 220v) or from 11kv to 380v?

Our standard is same as that europe's. no problem

How much power do you want? Kw,

pwer factor corrector is another thing which is different from regualtor.

Most of invertor (fsd) can work at 250v without problem.

but why do you getso higher voltage in UK? but theirs is usal 220v.

see the link above this is the voltage optimization technology which i am refering to.does anyone have any experiance of it?

(From the powerperfector site)

It's effectively a large transformer performing a voltage step-down along with some power filtering (due to inductance, etc).

How did powerperfector calculate a 5 year payback for your site? Did they perform an actual study of your site, or are they quoting a "guess" they made up. Although the product works, don't believe all the "best benefit" claims as they were on a particular site which was not the same (and probably a lot worse) than yours.

Based on what you have said regarding your site, small and inexpensive step-down transformers on selected pieces of voltage-sensitive site equipment would be a much better economical option than this (which is effectively filtering the entire (or large parts of the) site). For your application using a powerperfector unit would be like "using a sledgehammer when you only need a regular hammer", in that it would work but you are paying for a lot you don't really need or are getting benefit from.

If you can get proper validation of the payback claims and benefits from powerperfector on "your" particular site then it is probably worth it in the long run.

Its pity, I cannt access to the web site. but from the piture picked up by jack of all trades, I think its a step auto self regulator. 5 year payback for your site is sometimes a only advertisement. Im afraid. as we all know the higher voltge the empty load current the larger.

you can go to madeinchina web site for stepless regualtor, which I recommand to sell to you. can decent from 250v to 220v in 2mS response. single ro 3 phase all have.

but you havnt told us how much the power is? so that I can recommand a suitable one.

Hello

What did you decide about this equipment? I am looking at something similar for a number of council buildings in the UK.

Thanks

RJG

the company bought the equipment which has now been in 4 months and will get pay back in 3.5 years according to latest energy bills

Hi, i'm Energy Projects Engineer for a local authority in the UK - I have installed 15 of these units this year - any questions get me on allan.campbell@southlanarkshire.gov.uk

Regards

Fifteen units and I bet they weren't cheap. There are a number of other suppliers out in the UK market who I am sure would have given greater value for money.

Please get in touch with Alternenergy who are expert in all low energy solutions. They will survey your building free of charge and give you all the low energy solution you want. The supply and install all the technologisies. They can also get you an interest free loan over three years which usually is within the payback period so you will have no capital expeniture.
