Effect on tip load of large pole plants such as pole mounted transformers are calculated as:
Ftip = P * A* (hplant / hpole)
Ftip = Pole tip load (kN)
P = Design wind pressure on plant (kPa)
A = Area of plant exposed to wind (m2)
hplant = Center height of plant equipment (m)
hpole = Pole height above ground (m)
Power Lines Pro currently does not account for the vertical force - only the wind pressure.
