The equation of towers height calculation carryingpower transmission lines at their
intersection with engineering installation is one of the methods of designing power nets,the
solution of which depends on the traditional method for calculating con
ductors
coordinates. Sometimes this problem becomes so complicated or impossible to solve,
therefore, we have to use the space solution mainly when the wind direction made an angle
with these transmission lines and the points of hanging height difference. In this case it is
better to use the vector method which we used at the present work. We used a
mathematical model to calculate the minimum point coordination of the transmission lines
curves and the minimum distance between the engineering installation and that of these
transmission lines, and the suitable carrying towers heights, a cording to the permissible
electrical equipment laws. So we could find the suitable towers height coordinates by using
the C++ applicable program.
Calculation errors between traditional and vector method reaches high value which
increases with the slope angle increasing of conductors.
