Thanks again. No, I haven't heard of those sites before today. I tried some of them without success. I was looking for a book entitled 'Transmission and Distribution Electrical Engineering' by Colin Bayliss (3rd edition). The first link you gave me, well, when I went to it, but had a little bit of trouble because after I translated the site to english, not all of it translated. I did try some of the downloads for the book, but they wouldn't work for me. I'm not sure what the problem is. Any ideas or other sources?
In any case, I appreciate your time and help.
