Effect on tip load of large pole plants such as pole mounted transformers are calculated as:

Ftip = P * A* (hplant / hpole)

Where

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)

Note: Power Lines Pro currently does not account for the vertical force - only the wind pressure.
