I do not know the answer to your question other than to say that I think operating near primaries takes a lot of specialized training and specialized equipment. If a primary voltage were to hit someone, I get the impression the person would be very lucky to survive it, and if they do, they will probably be missing a large part of their body. It will burn a person from the inside out, along the entire length of the path that the electricity flows. Horrific injuries are the result. I would say, as an amateur, that such work should be left to the folks who work for the power company.Is it cool to fly bucket between primaries and CATV? If so when and who?
