Course Description

The purpose of this course is to teach you how to use the PLS-CADD computer program. This computer lab course includes background theory and hands-on computer modeling. Lectures will present the basic concepts, and computer exercises will illustrate them. Numerous case studies will provide a range of real-life examples.

Course Objectives

  • Apply and gain a good working knowledge on 66&11 kV OHTL design using PLS-CADD.
  • Recognize terrain modeling covering the various aspects including organizing. project files, viewing commands, opening of windows and viewing of phases and sags.
  • Prepare a terrain model, generate and edit features codes data and import XYZ terrain models.
  • Create alignments, profiles and side profiles, multiple alignment options, TIN terrain models and break lines.
  • Identify where to get conductor data and the design criteria to limit the Aeolian vibration
  • Determine conductor design and modeling and identify the various conductor types, permanent deformation from overloading and creep, effects of high temperature on creep and strength reduction, aluminum in ACSR conductors, conductor model in PLS-CADD 4 and stress strain charts.
  • Illustrate structural design of poles, towers and frames of different materials and apply structures modeling by allowable spans, sag and tension calculation and optimum structure spotting.
