Edward, How good is your grounding in the basics of Electricity?. Believe me, you WILL need this if you are to work with MV or HV lines or equipment. Work like this is VERY dangerous, if you are not conversant with current procedures and Safety requirements.
Trumpy, I do not know about the MV & HV grounding,However, I am knowledgable about the basic grounding. I know i will not start at the top of the transmission tower, But that line of work is very exciting. IMO
