I beg to differ. Beave's link was describing:
$1:
Neutral to earth voltage (NEV) specifically refers to a difference in potential between a locally grounded object and the grounded return conductor, or neutral, of an electrical system.
'Voltage' cannot flow without a conductor, and the voltage in power lines is specifically chosen so that it cannot use air (even humid air) as the conductor. Tower design prevents the tower from doing this as well.
Whereas, even in his article it describes:
$1:
Induced voltages
Classical electromagnetic induction can occur when long conductors form an open grounded loop under and parallel to transmission or distribution lines. In these cases, current is induced in the loop when a person makes contact with it and ground. Since this involves real current flow, it is potentially hazardous. This type of induced current occurs most often on long fences and distribution lines built under high-power transmission lines.[8][9]
Which can only occur with the
magnetic field that power lines generate. I spent all that time with 72 virgins and all I gots was an engineering degree.
So I maintain, with respect to power lines, 'stray voltage' isn't a thing.
