Electric power can be transferred either by underground cables or overhead lines. Underground cables are not commonly used for power transmission over long distances for economic reasons.

Overhead lines are subjected to various weather conditions and other external interferences. This requires the use of adequate mechanical safety factors in order to ensure the continuity of line operation. Typically, the strength of the line needs to be such that it can withstand the worst probable conditions. This course focuses on the different aspects of mechanical design of overhead lines.

This course is intended for engineers with a desire to understand the basic elements of overhead lines, design principles, calculation methods and factors that affect overall current carrying capacity.

Learning Objectives

Upon completion of this course, participants will be able to:

• Identify main components of overhead lines.
• Classify insulator types.
• Describe string efficiency.
• Analyze corona effect and factors that affect it.
• Explain sag in overhead lines.
• Compare factors that affect sag in overhead lines.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 30 questions. CPD credits are not awarded until the course is completed and quiz is passed.
