Overhead Power-lines Design: Transmission & Distribution

Overhead Power-lines Design: Transmission & Distribution

Course aims to cover fundamental concepts associated with the physical design of Overhead Power-lines (OHPLs) in a structured way so that it’s easy to digest for the audience coming from different engineering backgrounds.

Course is divided in 8 major sections with each section discussing one of the main aspect of the Overhead Power-lines. Brief overview of what to expect in this course:

• Common power-line definitions.

• Different structural design approaches to OHPLs - Deterministic design approach, Ultimate load design and Reliability based design methods.

• Mechanical loading criteria- Weather related loads, failure containment loading , construction and maintenance loadings, structure strength and overload factors.

• Conductors & Overhead Ground wires - Common conductor types, conductor selection considerations, OHGW selection considerations, design tension limits, sag tension calculations, conductor behaviour such as creep, temperature and tension effects on the conductor, and typical conductor motions like Aeolian vibration and galloping.

• Power-line structures: Structure classifications & different material types i-e wood, steel (monopoles & lattice)

• Insulators & Hardware: Insulator function, material type, typical arrangements and the design criteria. We will also discuss power-line hardware.

• Electrical Considerations: Different type of electrical stresses, electrical clearances, insulator swing calculation, radio interference and induction.

• Power-line design: Line layout and routing considerations and procedure, Right of ways and right of way width calculation, conductor & structure selection considerations, line loading criteria and typical power-line engineering deliverables.
