During live line maintenance, the lineman becomes very close to the power line conductors which would result in the exposure to high levels of magnetic fields associated with high levels of currents induced inside the lineman body. In this paper, the different types of live line maintenance are presented.
The magnetic field distribution over the lineman body is evaluated at different positions on the towers of 500 kV and 220 kV lines. The study considers the typical positions occupied by the lineman during his live line working conditions. In addition, the magnetic field is statically tabulated for different sections over the lineman body.
