IEEE: The expertise to make smart grid a reality

Approved & Proposed IEEE Smart Grid Standards

Approved and proposed IEEE smart grid-related standards, including those called out in the NIST Smart Grid Interoperability Standards Framework, are available for purchase. IEEE smart grid standards are also available in our IEEE Standards Online Subscriptions.

C62.11a-2008 IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits (>1 kV) Amendment 1: Short-Circuit Tests for Station Intermediate and Distribution Arresters

Metal-oxide surge arresters designed to repeatedly limit the voltage surges on 48 Hz to 62 Hz power circuits (>1000 V) by passing surge discharge current and automatically limiting the flow of system power current applies to this amendment. This amendment covers devices for separate mounting and to those supplied integrally with other equipment. The tests demonstrate that an arrester can survive the rigors of reasonable environmental conditions and system phenomena, while, at the same time, protect equipment and/or the system from damaging overvoltages caused by lightning, switching, or other undesirable surges.

C62.39-2012 - IEEE Standard for Test Methods and Preferred Values for Self-Restoring Current-Limiter Components Used in Telecommunication Surge Protection

This standard sets terms, test methods and measurement procedures for series connected, self-restoring current limiter components used in low-voltage telecommunication circuit surge protectors. It is only applicable for components in telecommunications circuits with voltages equal to or less than 1000 V rms or 1200 V dc. The self-restoring current limiters covered by this standard have the following properties: · Excessive current causes a transition from a low-resistance state to a high-resistance state · Reverts to a low-resistance state when the excessive current ends · Directly operated by the current flow through the component · Solid-state (no moving parts) · Withstands specified levels of impulse · Withstands specified AC voltage levels when in the high-resistance state Examples of this type of current limiter technology are positive temperature coefficient step-function thermistors of ceramic or polymeric material and silicon semiconductor based electronic circuits. This standard does not cover self-restoring current limiter components used in other applications, such as heaters, inrush-current limiters or sensing devices. Current interrupting type components, which reduce the current to zero by a mechanical circuit break, are not covered by this standard. In this standard, a telecommunications circuit is a circuit that uses metallic conductors to handle the remote transmission of information, such as data, communications and signalling.

42010-2011 ISO/IEC/IEEE Standard for Systems and Software Engineering -- Architectural Description

The scope of this standard encompasses those products of system and software development that capture architectural information, referred to as "e;architectural descriptions"e;. This includes architectural descriptions that are used for the following: a) Expression of the system or software and its evolution b) Communication among the stakeholders c) Evaluation and comparison of architectures in a consistent manner d) Planning, managing, and executing the activities of development e) Expression of the persistent characteristics and supporting principles of a system or software to guide acceptable change f) Verification of an implementation's compliance with an architectural description g) Recording contributions to the body of knowledge of systems and software architecture

IEC 61588 Ed.2 (2009-02) (IEEE Std 1588™-2008): Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

A protocol to synchronize independent clocks running on separate nodes of a distributed measurement and control system to a high degree of accuracy and precision is specified. The protocol is independent of the networking technology, and the system topology is self-configuring.
