Converting 220V Single Phase to 380V

I wouldn't. Electricity can be lethal in un-qualified hands.

No offence intended but what you are proposing sounds like a fatality waiting to happen.

Consult a qualified electrician and have your power requirement installed properly and safely.

you can get 380 V by combining 2 sockets, provided these two sockets are fed from two different phases. In simple words if you are receiving 3 phase supply in your apartment, you can get 380V.

Depends on a lot of issues related your distributed power supply, but the 99.9% answer would be NO.

IF your PoCo delivers 380Y220 3 phase to your building, and

IF your building owner distributes said 3 phase supply evenly to each unit, meaning some of the sockets are tapped into at least 2 of each of the 3 phases, and

IF you can determine which ones those are (not likely, being that you are even asking this question), and

IF you can determine which of each prong in the outlet is Neutral and which is Line (again, unlikely), and

IF you could SAFELY connect to 2 of these 3 disparate phase circuit relationships (again, your asking this question denotes a lack of understanding, which decreases the likelihood of your knowing how to do this SAFELY),

THEN maybe you can pull off getting 380V Line-to-Line

Put a motor-generator set, the generator will give you the desired voltage, forget the transformer it is an old technology.

As others have said, the short answer is no unless you use a step-up transformer or a (rather loud for an apartment) gen-set.

What is the load you are trying to power and why don't you care if is single (unlikely)or three phase (likely) 380V?

Something sounds very strange here? Please provide as much information as possible.

It is a big electromagnet.

It only marks 380V and only have live and netural wires.

But I connected this to 220V single phase AC, it worked.

I think if I change to 380V, it will get stronger, just back to its designed power.

Yes it likely will if it is designed to operate up to 380V AC (but is it designed to operate on AC?)

Regardless it is unlikely you can easily get 380V AC in your apartment room without major expense, effort and the assistance of an electrician. Even if you had access to a two or three phase socket or supply (such as perhaps the kitchen stove power supply) this is still quite a dangerous project for what appears to be a general interest experiment and I would STRONGLY recommend against it for electrical safety and fire hazard reasons.

Play safe!

What's your location? If your system is 3-phase 380Δ220Y, 380V will already be available (line-to-line). However, adding a substantial 1-phase load will alter the system balance.

some of the answers to this question should be commended

others should be committed

let the mechanics fix the cars, the plumbers aim the toilets, and the electricians.....aaww never mind

*it's been a bad day so what's the use*

Hear Hear

I agree with this reply

To the OP.. I'm not sure if you are really stupid or just trying to get a rise out of the forum.

whichever.. remember this; Electricity... you can't see hear or smell it, but it got one hell of a bite.

Please ask you family to let us know when your funeral is, so we can send flowers,

don't be a moron all your life take a day off!!

Why? What are you trying to achieve? Please dont play with electricity

You should be able to utilize a single socket and a single phase to three phase inverter (AC Adjustable Speed Drive) for this application, provided you are willing to make the expenditure. These inverters are usually limited to about 1 kilowatt.

My dear friends of CR4

Take a step back and read what you have written... the majority of you are condoning and encouraging stupidity.

Please stop trying to prove how smart you are and think before you reply to stupid questions.

This person has no clue about his own safety and that of others, has no consideration for others and has no idea what the results would be of his actions and you are telling him how to kill himself.

I'm not sure who is worse... the OP for asking the question or some of you for giving him some sort of answer. Can you not see this Op has no idea what he is trying to do, what he want to do it for and has no technical ability to achieve it. The result will be fatal.

Furthermore some of the answers are bordering on dangerous, so I wonder about the technical abilities of some of you.

This forum is for like minded people to help and discuss ideas, voice problems and to share knowledge.. NOT help kill stupid people.

Then again some may say a "cull" is required.....

I agree with you.

Even if the OP does not get killed trying to connect this electromagnet, I would ask: what does he needs this electromagnet for? in an apartment? That power seems like an industrial use, not a domestic one, and certainly not for someone who is clueless about electricity. I mean, 380 V is big deal the same as 240 V, being one phase or two it will certainly kill someone and is fire hazard!!!

Also an AC electromagnet seems wierd!

thanks

I have reported this OP question and answers and asked for removal

This is a great favor to all, I back you up. GA to you

in a word Yes

Anyone stupid enough to ask the question is going to be hell bent on carrying it through and deserves to be left as ignorant as when they first started, I cannot be party to stupidity.

We call ourselves clever, yet rather than NOT answer this ridiculous OP, we encourage it, we try to SOLVE is problem, we are signing his death warrant. The latest reply... don't be cheap.. buy a transformer!!

What the hell does that mean?

I will repeat myself.. we are to concerned in showing how clever we are to see the danger we pose to others. A little knowledge is dangerous.. in this case it WILL kill someone.

Read the Op.. it is staring you ALL in the face that this OP is NOT technically minded and has no technical training of even the basic kind.

What next.... DIY brain surgery on CR4??????

As for good information, its not that good, don't fool yourself, it is poor and misguided. There should NEVER have been one answer to this OP, or it should have been removed, but can we?

NO.. we have to show to the world how clever we are and at the same time blinker ourselves to the real danger

We read but yet we do not understand, may our common sense RIP

Don't be cheap and hurt yourself, buy the proper transformer.

Your safety more important than saving money.

Your cheap measuring instrument is defective and grossly inaccurate, borrow mine it will read 380V AC at the existing sockets marked 220V by yourself
