Active IEEE Standards
After the final approval by the IEEE SA Standards Board (IEEE SASB), the approved standard is published and made available for distribution and purchase. Learn more about what happens to an IEEE Standard after approval and how it’s distributed here.
Active IEEE Standards are living documents, which may initially be published and iteratively modified, corrected, adjusted, and/or updated based on market conditions and other factors. Depending on where a standard is in its lifecycle, a standard may be accompanied by additional documents that are produced by its respective Working Group. These may include amendments (which modify sections of the standard), or corrigenda (which only correct errors or ambiguities in a standard). An errata, which addresses errors in the standard introduced during the publication process may be issued by the IEEE SA Editorial staff. Learn more about maintaining an IEEE Standard here.
IEEE Standards in Development
The IEEE Standards Development Life Cycle is broken down into the following stages. These steps were developed using a time-tested, effective, and trusted process to provide foundation standardization on which technology innovation is based.
Active PES Standards
- IEEE C37.90.1-2024 - IEEE Standard for Relays, Relay Systems, and Control Devices used for Protection and Control of Electric Power Apparatus–Surge Withstand Capability (SWC) and Electrical Fast Transient (EFT) Requirements and Tests
- IEEE 1122-2024 - IEEE Standard for Digital Recorders for Measurements in High-Voltage and High-Current Impulse Tests
- IEEE/IEC 63253-5713-8-2024 - IEC/IEEE International Standard – Station Service Voltage Transformers (SSVT)
PES Standards in Development
- PC57.20 - Guide for Power Transformers for Low-frequency (10 Hz to 30 Hz) Power Transmission
- P2882 - Guide for Validation of Software Models of Generators for Power System Studies
- IEEE P1186 - IEEE Draft Recommended Practice for Applicability of Methods for the Evaluation of Low-Voltage and Medium-Voltage Installed Cable Systems in Nuclear Facilities
Highlighted Standards
Standard Number: IEEE 1264 – 2022: IEEE Guide For Animal Mitigation for Electric Power Supply Substations
Standard Description: Documented in this guide are methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Standard Number: IEEE 1366 – 2022: IEEE Guide For Electric Power Distribution Reliability Indices
Standard Description: Distribution reliability indices and factors that affect their calculations are defined in this guide. The indices are intended to apply to distribution systems, substations, circuits, and defined regions.
Standard Number: IEEE/ASHRAE 1635 – 2022: IEEE/ASHRAE Guide for the Ventilation and Thermal Management of Batteries for Stationary Applications
Standard Description: Vented lead-acid (VLA), valve-regulated lead-acid (VRLA), nickel-cadmium (Ni-Cd – both fully vented and partially-recombinant types), and Li-ion stationary battery installations are discussed in this guide, written to serve as a bridge between the electrical designer and the heating, ventilation, and air-conditioning (HVAC) designer. Ventilation of stationary battery installations is critical to improving battery life while reducing the hazards associated with hydrogen production (hydrogen production is not a concern with Li-ion under normal operating conditions [it is under thermal runaway conditions]). This guide describes battery operating modes and the hazards associated with each. It provides the HVAC designer with the information to provide a cost-effective ventilation solution.
