Working Group Details
IEEE Standard for Series Capacitor Banks in Power Systems
This standard represents a significant update to IEEE 824-1994. Series capacitor bank component and bank duty cycle ratings, equipment insulation levels, protective functions, component testing, instruction books, nameplates, and safety are covered in this standard.
IEEE Guide for Determining the Effects of High Temperature Operation on Conductors, Connectors, and Accessories
The purpose of this guide is to provide general recommendations for consideration when designing new overhead transmission lines that will be operated at high temperatures. It may also evaluate existing transmission lines for operation at higher temperatures. Although this guide is intended for overhead transmission lines, most of the discussion will also be applicable to distribution lines.
IEEE Standard for Fall Protection for Utility Work
General recommendations for fall protection and worker protection are provided. Sufficient details of the methods, equipment, and training requirements necessary to provide minimal risk procedures for personnel working at elevated worksites are presented.
IEEE Guide for Application and Specification of Harmonic Filters
Guidelines for specification of components, protection, and control of harmonic filters are provided. This guide applies to the use of 50 Hz and 60 Hz passive shunt power harmonic filters on low- and medium-voltage electric power systems. This document is the first guide specifically created for harmonic filters, although standards do presently exist for most of the components that are used in a filter. Applications including industrial low-voltage facilities, utility medium-voltage systems, and arc furnace installations are covered.
IEEE Guide for Inspection of Overhead Transmission Line Construction
Withdrawn January 2012. This guide covers various approaches to good inspection practices for the construction of overhead transmission lines. Inspection responsibilities and reporting as well as inspection of various overhead transmission line components are discussed. The guide is intended to be used as a reference for those involved in the ownership, design, and construction of overhead transmission lines.
IEEE Guide for Application of Composite Line Post Insulators
An application guide for non-ceramic line posts is being drafted. The guide will include handling recommendations, interpretation of manufacturer ratings, contamination considerations, and equivalency with porcelain. Project purpose: Users of non-ceramic line posts have questions regarding the use of the products which are not answered due to the lack of any official standard.
IEEE Standard Procedures for the Measurement of Radio Noise from Overhead Power Lines and Substations
Uniform procedures are established for the measurement of radio noise generated by corona from overhead power lines with meters that conform to ANSI C63.2-1980. The measurement procedures are also valid for other power-line noise sources such as gaps and harmonics; however, most of the precautionary information, analys is, and data plotting techniques were written and developed primarily for corona discharges. The procedures are not valid for measuring transient radio noise sources that occur during breaker or disconnect switching operations. Procedures are suggested for measurements in and near substations. This standard is applicable to both AC and DC transmission lines and substations.
IEEE Guide for Application of Composite Insulators
A guide to the application of composite insulators to overhead transmission and distribution lines is provided. It is based on utility field experience, results of research laboratory tests, and manufacturers 'recommendations. The guide deals with composite insulators, which include a core, weather sheds, and metal end fittings. The core consists of resin and axially-aligned glass fibers. The weather sheds are of polymeric materials.
IEEE Guide for Analysis and Definition of DC Side Harmonic Performance of HVDC Transmision Systems
Guidelines are provided for evaluating and mitigating harmonic induction effects from high-voltage direct current (HVDC) lines on the adjacent telephone communication lines. Specifically, this guide presents methodology and approach for a) Determining the number of wireline communication circuits that will be affected by unacceptable interference and cost-effective remedial measures; and b) Computing interference levels that would result with various practical dc filter/smoothing reactor designs and the costs of these filters.
IEEE Guide for Preservative Treatment of Wood Distribution and Transmission Line Structures
This guide discusses the preservative treatment of both distribution and transmission wood poles. The guide includes definitions, descriptions of equipment, methods of treatment, information about preservatives, and preparation and specifications for treatment.
IEEE Guide on Conductor Self-Damping Measurements
Reaffirmed September 2007. Methods for measuring the inherent vibration damping characteristics of overhead conductors are presented. The intent is to obtain information in a compatible and consistent form that will provide a reliable basis for studying the vibration and damping of conductors in the future, and for comparing data of various investigators. The methods and procedures recommended are not intended for quality-control test purposes.
IEEE Guide for Laboratory Measurement of the Power Dissipation Characteristics of Aeolian Vibration Dampers for Single Conductors
The current methodologies, including apparatus, procedures, and measurement accuracies, for determining the dynamic characteristics of vibration dampers and damping systems are described. Some basic guidance is provided regarding a given method's strengths and weaknesses. The methodologies and procedures described are applicable to indoor testing only.
IEEE Guide for Transmission Structure Foundation Design and Testing
The design of foundations for conventional transmission line structures, which include lattice towers, single or multiple shaft poles, H-frame structures, and anchors for guyed structures is presented in this guide.
IEEE Guide to the Assembly and Erection of Metal Transmission Structures
Various good practices that will enable users to improve their ability to assemble and erect self-supporting and guyed steel or aluminum lattice and tubular steel structures are presented. Construction considerations after foundation installation, and up to the conductor stringing operation, are also covered. The guide focuses on the design and construction considerations for material delivery, assembly and erection of metal transmission structures, and the installation of insulators and hardware. This guide is intended to be used as a reference source for parties involved in the ownership, design, and construction of transmission structures.
