transformer ratings ??

I don't mean to be negative, but how on earth do you expect any of us to venture an opinion on this ? You don't even say what the transformer is fitted to. It could be anything from a dental x-ray machine to a transistor radio ...

If it is in a piece of commercially produced equipment, then the chances are that it is a custom model specced by the company that built the equipment, in which case, it should only be replaced with an original spec transformer, as generally, this is a "designated safety component" , and if you replace it with a substitute, you are leaving yourself wide open to some serious trouble if it fails down the line and causes a house fire or whatever.

arfa ,

Thanks for your answer.

If any info would be available , i think it was not needed for me to call in the help of a newsgroup.

No, as you provide no relevant info at all.

In order to call in the help of a newsgroup, you need to supply some basic information. In view of your ridiculous request for help based on the information you did give, I tried to be polite to you. Had others on here got there first, you would likely have had your nose put out of joint far worse than you perceive that you have had by my reply. Do not try to put it back on me or the group.

And don't top post.

Yeah, you are right, because all the readers of this newsgroup have crystal balls specially designed to answer any question posted by any clueless person. On that context, asking you a little bit of info is absolutely a sacrilegy, and as such it goes against the rules of this NG.

Problem is that we don=B4t have cristal balls, nor we can find brand new ones, so UNLESS YOU PROVIDE US WITH SOME MEANINGFUL INFO about the brand, model and type of equipment where such transformer is used, and the number of taps that transformer has in its secondary, NO ONE will be able to help you. If you are unable to provide such basic information THEN you aren=B4t qualified enough, or smart enough, to repair the equipment you are trying to fix.

Not without a crystal ball, there's no way at all to know from the info you gave.

What is the transformer used in? That will provide clues as to what ratings are required.

hmm, is this in a switching power supply as it sounds to me it is the switchmode transformer and you don't just buy them off the shelf. If it's not an expensive piece of equipment, best to replace the whole supply.

Why do you think it's "gone"?

If this is a switchmode power supply transformer, some of the windings will read very cloes to 0 ohms and that's normal.
