Nowadays, a significant trend in load increase in industrial areas, shopping malls, and residential areas. It requires upgrading and enlargement of power systems and utility grids. Maintaining power performance criteria such as reliability, voltage stability, and frequency stability would be of utmost importance in a reliable power system. This can be achieved by designing highly reliable bus bar configurations, and interconnecting transmission lines, zone substations, and distribution centers. It also required more power plants and embedded generation facilities in appropriate locations.

The Fundamentals of Overhead Transmission Lines training course covers electrical, mechanical, structural, and civil aspects with respect to the design of overhead lines. Electrical aspects include insulation coordination, earthing, EMF, and EMC. Tower types and tower families and structural aspects such as tower strength and stiffness are addressed, as well as foundation design, insulators, and different conductor types and their behavior under climatic loading.


At the end of this training course, you will learn how to:

  • Model a power system by means of system parameters
  • Create different load flow scenarios through different switching regimes
  • How to analyze and interpret the response of the power system to different scenarios
  • How to modify the power system behavior in an area by enhancing system parameters
  • Create and analyze protection curves to achieve coordination between different bays
  • Tower types and tower families
  • Tower loadings and tower design
  • Insulation coordination
  • Lightning protection systems and performance
  • Overhead lines towers Foundations
  • Earthing systems
  • Overhead lines Conductors
  • Insulators and surge arresters
  • Electromagnetic fields, electromagnetic compatibility


We encourage the staff involved in the operation, planning, design, and maintenance of power systems to attend this training program. This training is suitable for a wide range of professionals but will greatly benefit:

  • Project Engineers / Managers
  • Electrical Engineers / Technicians
  • System Operators
  • Design Engineers
  • Asset Engineers / Managers
  • Planning Engineers / Managers
  • Protection, Instrumentation, and Commissioning Engineers / Technicians


This training seminar will utilize a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. It includes case studies where the participants are required to take part in class activities including system analysis, calculations, relay settings, etc. The instructor will also use training videos for better understanding of the participants. The participants will be progressively assessed during the training seminar via quizzes, questions, assignments, and worked examples.

Pre & Post course assessments will be used to measure the effectiveness of this training.
