Voltage Stabilizer

07/20/2007 12:16 AM

Guys,

Kindly please help me to get three phase voltage stabilizer :

input/output: in:15%, out:0.5% 380V to 415VAC 50Hz three phase

response speed: 1cycle or below

capacity: 400 to 500kVA

thanks, guys.

If you don't even know how to stablilize current, which must be the first step before you even attempt to transform it, then you have know business messing around with it.

LEAVE IT ALONE, and get a professional that knows what they are doing. do you even know what happens if you try to make 3phase from an uneven source? LEAVE IT ALONE, and learn what the hell you're doing first before you kill someone or yourself.

Hello Guest,

Not that I totally disagree with what you are trying to say, but let me suggest that first, go learn some English. Second, from reading your answer, I am not so sure you know much more about the subject of electricity than our poster, as a matter of fact I am quite convinced that you know very little. Third and maybe the most important, learn to be more humble and polite. It didn't do any harm to no body.

Wangito.

Guests like you have no business in this forum. The use of obscene language is not permitted here. I will do my best so that you will be expelled.

you criticise my direct use of language yet hold that attitude?

Like I said, leave it alone. until you learn what you're doing, you could cause power spikes that would kill people, and blow machinery.

as for the judgemental of the jugdemental, easier to hate people huh? even when you're told in no uncertain terms the danger, you'd rather criticise someone for being straight about it rather than have/admit a sense of caution? I know who the wise would follow, and its not your advice.

"It didn't do any harm to no body."

LOL!

I think you mean "It didn't do anybody harm." or "It did harm to nobody" or better yet, "It did no harm". Your statement as typed is a double negative, indicating you are a pot calling the kettle black!

Just a little thing to know about you, Guest : are you a phanthom? or Flash, son of thunder? will you show me your identities then hiding?. Can I contact you by phone or personnel email to discuss in deep technical issues?

"If you don't even know how to stablilize current", you said "stabilize current", do you know how? to my technical term, there's no such way to stabilize current in lagging, resistive load, and i don't think so in leading load, too. But there's exactly a way to stabilize voltage.

What I want you to help me is tell me a manufacturer name or some whom provide goods i'm searching for. Next, I have my self engineering procedure.

Furthermore, I feel likes talking to my kid. Sorry, just don't have time to waste.

Sorry if I seemed to come on too strong, but its something you really need to understand fully. 2 or 3 spikes in close occurance can cause machine failure, or kill. its that harsh.

sorry, I don't know anyone in your area that will meet your needs, I suggest you go to the sparkies "electricians" the local ones, and ask them for help.

I do know some basic sinusodal rectification, that will demonstrate methods employed to retify and even waves thus to tranform into 3 phase, but even better than that is in ensuring the correct angles in the fabrication of the generating mechanism, so that you get an even single phase wave damn near perfect. From there, a sparky will be able to phase into 3 phase, and you should be able to get a transformer capable of meeting your needs.

other than that, I don't want to be contacted by anyone, nor get involve with such longrange and fruitless endeavours (from my perspective) which doesn't mean that you're not capable of achieving your goals. I only offer-on advice here on this site, and in the moment I do so.

maybe its not such a bad thing to go play with your kids, especially if you can't see your way forward.

Mr. ???guest???,

Thanks for your concern. About power quality it's been covered by IEEE 1159-1995 standard, there're explained in detail, including transient, its durations, and its inside and outside sources.

About machine failure or kill and it's voltage withstand against surge, it's been covered by IEC 60364-4-44, there're explained in detail include its categories.

About kill which is meant safety to human, it's been covered by IEEE 902-1998. I could send you a copy if you display your contact address.

The rests, it seem like you're talking about switching of power SCR or THyristor, I haven't go to sparky as suggested yet. Thank's GOD, I have observed what you're concerning, anyway thank to you, it's been covered in IEEE 1159-1995 above.

Can you suggest me another, like what about the experience of applying Electroflow's product or ashleyedison's product? or anyone?

In term of science, "nothing is impossible". The sun is never wet, no reason to stop seeing forward. These italic words are typing by 7-years kid. I'm just smiling watching sitting nearby.

Hi Abu Khansa,

Don't waste your time on our unwanted guest. nothing good will result from any discussions with him. It's the type of "Mr. Know it all". Just ignore him as I do.

Keep asking, keep learning.

God bless

Wangito.

Do you even realize what you are asking for?You are asking for a 3 phase stabilizer with 15% input variation with 0.5% output regulation in 500 KVA capacity? On top of this you want correction in a single cycle?

Only way you are gonna get this is to buy an ultra high quality & reliability ONLINE UPS of that capacity.

And believe me that baby is going to cost a pretty penny with all kinds of battery banks and pure sine wave inverter & what not.

Look for a UPS System [Redundant System] for 400 to 500kVA is needed.

The modern equipment as has already been mentioned is an On-Line UPS, big Dollars for sure. Another option that may suit your application is a Synchronous Motor/Alternator set with a large flywheel. A servo-mechanical regulator would cope but the response time would be too slow.

have a look at elspec's Equalizer system which provides voltage support, Power factor correction, flicker reduction, current spike reduction, harmonic filtration, energy savings and many other applications for a variety of dynamic loads
