If we know there's construction happening and it's on a loop we'll usually cut an open in to deenergize the line if something like that is going on.We have done crane pics around high voltage
how many voltages I don't know. But we had a power plant and it was the wires going to the grid
But I would get real nervous with that damn crane up there and constantly question the crane operator about it
One of my dads friends is a well driller and he boomed up into a line, got killed by the voltage going through the winch sized lead going to the control in his hand. I doesn't take much...
