Yes, I can help, study all the material you have concerning transformers.

Seriously, if you are taking an exam and are not ready with the study material given to you, then the help you will recieve here ( from some of the best IMO) will not get you through the exam with a passing grade.

If you were to ask a specific question that had you stumped, and then showed your effort at solving this problem, you could feel certain you would recieve the correct answer from someone here.

One of the things you can do is go to google and search for transformer info, or just go to some transformer manufacturer's web sites for info. You will find more than you may wish for.

Study the basic fundamentals, then research every configuration possible.

If you don't already know the difference between the various connections, don't bother to take the test.

Study theory, forget the code, it won't make sense now.

Does your local have a training center?

You might have to hunt a bit, but Bussmann's web site has a lot of good info, including some power point stuff about transformers.

All the connections and formulas you will need are in the UGLY's hand book. Every one should carry one of these handy references.
