Transmission Line Design Using Bentley Structural/MicroStation, STAAD.Pro and Google Earth

Ravi Ozarker, P.Eng., Applications Engineer, Bentley Systems Inc.

Transmission towers have to be designed as per the applicable transmission tower design code using the analysis data obtained from design loads.  The design loads may most probably include dead, wind, snow/ice, conductor, and seismic.

 

 

Design of a transmission line involves checking for ground clearance (should include the sag of the conductors during operating conditions) distance of the live conductors, clearance of the conductors from the steel structure during high wind conditions, and length/configuration of the insulators.

 

 

The following video shows how engineers can design and model transmission towers and transmission lines using Bentley Products.  The Bentley Products that are shown in the blog are:

  1. MicroStation
  2. Bentley Structural
  3. STAAD.Pro

Adobe Acrobat and Google Earth can also help engineers throughout the design process.
