I think Lyledunn is right. I can't imagine there is a full year of knowledge in HV only. 2-3 years in HV will probably earn you a doctoral degree [Linked Image]

Just guessing from what little I have seen.

For example, there is a basic course how to run a power grid at the school where I've studied. The book is a 100 or so pages and the course is four weeks. Not real weeks, university weeks [Linked Image] If you want something more specific, you need to look in the grid operators manual. The situation will be similar in the other fields like design of HV lines.
