6.1 D-TEC Function

The task of accurately determining when it is safe to raise a mast near power lines is inexact at
best. The electric fields around power lines are perturbed by the presence of other objects,
other power lines, how the power lines are arranged on the pole, etc. In some cases, the fields
can extend quite a distance from one side of the lines, and fade abruptly on the other side of the
power lines. Therefore, as was mentioned previously, the D-TEC cannot be used blindly or
relied upon without caution. It is simply a tool to help raise your level of caution. See Figure 6-1
and Figure 6-2 for indication of how some cases of electric and magnetic fields are shaped.
