The purpose of this guide is to describe the current methodologies, including apparatus, procedures, and measurement accuracies, for the testing of vibration dampers. In addition, some basic guidance is also provided to inform the potential user of a given method's strengths and weaknesses (see clause 6). Due to the variety of vibration damper designs, more than one test method may be required to obtain the necessary information on dissipation characteristics. This guide is written to describe some of the procedures for determining the dynamic characteristics of vibration dampers and damping systems. It is intended that it will assist in the standardization of the methods included as well as result in providing a more detailed perspective in obtaining reliable information on a vibration damper's dissipation characteristics. Please note that the methodologies and procedures incorporated in this guide are applicable to indoor testing only and are in no way associated with the field testing of vibration dampers. By using the appropriate technique(s) outlined, data can be acquired that can be utilized in the application of dampers; however, this topic is considered beyond the scope of this guide. In general, it is intended that this guide will provide an improved understanding of vibration testing procedures.

P1283
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.
P1368
Guide for Aeolian Vibration Field Measurements of Overhead Cables
This guide provides current practices related to field measurements of aeolian vibration of overhead cables.
P3132
Guide for Application of Spacers and Spacer Dampers on Bundled Conductors
This guide introduces criteria for designing, testing, installation, inspection and replacement of spacers and spacer dampers used on overhead transmission lines.
P563
Guide on Conductor Self-Damping Measurements
This guide provides proven methods for investigators to perform measurements of the inherent damping characteristics of concentrically stranded overhead conductors. It details two forced vibration methods (power method and standing wave method) which enable comparison between various investigators.
P738.1
Application Guide for IEEE Std 738-2023 (IEEE Standard for Calculating the Current Temperature Relationship of Bare Overhead Conductors)
This guide provides details to support the application of IEEE Std 738-2023. The guide provides details on the use of IEEE Std 738-2023 for calculating conductor line ratings, including steady-state, transient, ambient-adjusted, and dynamic line ratings. Because IEEE 738-2023 does not recommend suitable weather conditions or conductor parameters for use in line rating calculations, this guide discusses the selection of conductor parameters, weather parameters, and environmental conditions, and their impact on line ratings.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
738-2023
IEEE Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors
A numerical method by which the core and surface temperatures of a bare overhead conductor are related to the steady or time-varying electrical current and weather conditions is described in this standard. Contents discussed also include how this method may be used to determine the conductor's current for a corresponding conductor temperature limit. Please note the content in this standard does not recommend suitable weather conditions or conductor parameters for use in line rating calculations.
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
