Draft Standards

The C62.42 guide series covers surge protective components (SPCs) used in power and telecom surge protective devices (SPDs) and equipment ports.This part on high frequency signal isolation transformer technology SPCs covers: ⎯ Component construction ⎯ Characteristics ⎯ Ratings ⎯ Application examples

This Recommended Practice addresses system and equipment design techniques and equipment selection that can improve electrical safety. The techniques in this Practice are intended to supplement the minimum requirements of installation codes and equipment standards. It does not include...

This standard establishes environmental performance criteria for Complex Set Top Boxes (CSTB) relating to reduction or elimination of environmentally sensitive materials, materials selection, design for end of life, life-cycle extension, energy conservation, end-of-life management, corporate...

This guide consolidates useful information, methods, and reference materials that define the state of the art in the design of wood pole transmission structures, commonly in the 69 kV through 345 kV range, into one document. This guide addresses application of wood in transmission structures,...

This standard provides requirements to: (1) help utilities identify structures that may be at a high risk for below-grade corrosion; (2) excavate and inspect the selected structures; (3) categorize the condition of structures based on corrosion degradation; (4) prioritize structures requiring...

This standard provides requirements to: (1) help utilities identify structures that may be at a high risk for above-grade corrosion; (2) inspect the selected structures; (3) categorize the condition of structures based on corrosion degradation; (4) prioritize structures requiring additional...

This Guide documents accepted protection practices for transmission to generation interconnections. It is intended to cover the protection system applications at the interconnections between transmission systems and generation facilities greater than 10 MVA. This Guide does not cover distributed...

Mission critical entities have a strong preference for private, licensed networks in VHF/UHF frequencies for their data communications needs. VHF/UHF licensed channels narrower than 1.25 MHz are readily available in the secondary markets at a lower cost than commercial wideband channels. Example...

This International Standard specifies protocols and test procedures for the reproducible and conservative measurement of the power density (PD) incident to the head or the body by radio361 frequency (RF) transmitting devices, with a defined uncertainty. The protocols and procedures apply for a...

This International Standard specifies computational procedures using Finite-Difference Time-Domain (FDTD) and Finite Element Methods (FEM) to assess the peak and spatial-averaged power density relevant to human exposure from devices operating between 6 GHz and 300 GHz. It applies to devices with...

This guide addresses the application of tertiary and stabilizing windings in liquid immersed power transformers, as covered by IEEE Std C57.12.00, as well as recommendations to evaluate the need or convenience of having such windings. The primary application of this guide is for transformers and...

This guide will consider the components of both the ac and dc systems and provide guidelines and recommendations for designing the appropriate systems for the substation under consideration. This guide covers the low voltage auxiliary systems from the source(s) to the distribution point(s)....

The terms and definitions in the standard are intended to encompass the products within the scope of the C37 list of power switchgear standards for high-voltage circuit breakers (above 1000 Vac and 3200 Vdc) and for reclosers and other distribution equipment (above 1000 Vac to 38,000 Vac) as used...

This standard defines digital automated test program generator (DATPG) output data formats and informational content for unit under test (UUT) models, stimulus and response patterns, fault dictionaries, and diagnostic probing. These outputs provide a standard exchange format for automatic test...
