Reply by Jim, WD5JKO:


  A lot of the parameters you mention depend on the construction method of the transformer, and which way the cost versus performance ratio went.  I found a pretty good  tutorial on the web that  goes through a lot of this and a whole lot more.  

Take a look at Patrick Turners web site, the link below goes specifically to power transformers. He has a whole lot more stuff there too.
