Credit: 3 CPD

Length: 47 pages

This 3-hour course is the second in a series of three courses about the mechanical design of electric power distribution systems. The volume addresses conductor issues including sag, ruling spans, design tensions, Aeolian vibration, and clearances.

This course is divided into ten short chapters. It begins with an explanation of sag and tension in bare conductors. Ruling spans are explained including the various types of ruling spans. Conductor tensions and tension limits are reviewed. Example calculations are provided. Aeolian vibration is discussed as well as how to minimize the effects of Aeolian vibration. NESC conductor clearances are explained and methods for calculating proper clearances are discussed.

Learning Objectives

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

• Calculate sag and tension using appropriate calculation procedures.
• Explain concept of ruling span.
• Describe Design tensions.
• Determine conductor sags.
• Compute conductor clearances on structures.
• Estimate maximum spans based on vertical clearances.
• Quantify maximum spans for non-parallel conductors.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. CPD credits are not awarded until the course is completed and quiz is passed.
