Transformer Calculations

i realised i was in love with electrical design, now i am not grounded yet but on course to become a very gud electrical and automation consultant

Pardon me, but I am of the same opinion as TonyS.

You want to become a good Electrical Engineer, You are in love with Electrical design?

With due respect the way to be in love with this is to study and not get the ready made answers.

OK we give you the answer to the % impedance. But do you really know what it is? For that you should know the transformer design. And with due regards you may be in love with Electrical Design, but you don't know the simplest of them?

I feel I am harsh. But if you want to be a real good engineer and not an impressive one (for that you come over with the problem and search the answer in websites/ search engines/ forums like this and voila the customer is impressed) clear and brush off your basics.

I am now about 30 years off college. Electrical Engineer in mechanical field. And that is much more diverse than your five years in a semirelated field.

I too do the search for answers once in a while but then I look for technical papers (and one of the sources or links I do get from the forums). The answers from any forum for my type of questions, though are some times available, but rarely and may not be authenticated unless I gamble with someone customer's money equipment _{Your approach looks to be on this line.} One has to be hundred or nearby percent sure before taking a drastic step, which you would be required to take in future.

Go back to the basics and study if you do love the subject.
