3 phase transmission line above earth.
Plane-parallel problem of electrostatics.
d = 1 m, h = 5 m.
Model depth l = 4 km.
Relative permittivity of air ε = 1,
Transmission line of 3 conductors features self- and mutual- partial capacitances. It is convenient to use capacitance matrix calculator add-in to find all the partial capacitances.
