Possible adverse impacts to an operating overhead transmission line which might occur when operating the line at high temperatures are discussed. Specifically, the transmission line's conductor, connectors, and attached accessories in terms of degradation in mechanical properties due to annealing elastic and in-elastic elongation, and accelerated aging are explored along with limited mitigation recommendations. Additionally, predictor equations for accelerated creep and conductor loss of strength are detailed in annexes with limited example calculations.

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
Guide for Determining the Effects of Elevated Temperature Operation on Conductors, Connectors, and Accessories
This guide describes the effects and impacts of elevated temperature operation on conductors, connectors, and accessories. The guide identifies operating metrics which constitute elevated temperature operation based on present industry practices and its effects on overhead line components, and suggest potential mitigation options to manage and/or avoid identified adverse impacts.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
