Project: T183700 #3398B
 

The primary objective of this project is to review the current knowledge of “best practices” in designing EHV overhead lines. Primary focus here will be the mechanical aspects of line design. The information should be presented to TODEM members in a way that they can understand. It is also expected that the document will provide a quick reference guide so that a less experienced engineer can understand the issues and the technical content and follow the EHV line design process in a transparent manner. Another objective of this project is to educate the younger engineers who are joining our workforce at an increasing rate. The knowledge base for EHV AC line design is getting smaller due to the dramatic changes that have occurred throughout the industry over the past 25 years and many experienced engineers leaving the profession primarily due to retirement and/or restructuring of the industry.

TODEM members are aware of various publications available or produced recently by EPRI, CIGRE and others, but are interested in a practical guide which can be used by new transmission line engineers and experienced line engineers. It is expected that the guide on “best practices” deals with the subject in the most practical, useable ways. The intent is to produce a guide based on latest knowledge and proven experiences so that users do not repeat the same processes or use same methods which have produced unacceptable results in the past.
