IEEE 2030.10-2021

The design and operation of a dc microgrid for rural or remote applications based on extra low voltage dc (ELVDC) to reduce cost and simplify stability are discussed in this standard. Such microgrids are typically operated without connecting to a nation's electric power system.

IEEE 1349-2021

Three-phase and single-phase ac synchronous and induction electric machines in ratings 0.18 kW (1/4 hp) and larger are covered in this guide. Primary emphasis is on the use of open or nonexplosionproof or nonflameproof enclosed machines in Zone 2 and Class I, Division 2 locations as covered in the NEC(R) (NFPA 70-2020) and CE Code(R) (CSA C22.1-2021) as applicable. Surface temperature test methods and sine wave and non-sine wave applications are covered. Precautions against excessive surface temperatures and sparking are included. To help mitigate hot surface temperatures and sparking, this document provides guidance for selecting, operating, and maintaining machines in…

IEEE C37.04-2018/Cor 1-2021

This standard covers the rating structure for all high-voltage circuit breakers, which include all voltage ratings above 1000 V ac and comprise both indoor and outdoor types. Preferred ratings are also provided. Typical circuit breakers covered by these standards have maximum voltage ratings ranging from 4.76 kV through 800 kV, and continuous current ratings of 600 A, 1200 A, 2000 A, 3000 A, and 4000 A associated with the various maximum voltage ratings. The rating structure establishes the basis for all assigned ratings, including continuous current, insulation capability (formerly dielectric withstand voltages), short-circuit current, transient recovery voltage, and capacitor switching,…

IEEE 1901b-2021

State-of-the-art authentication and authorization mechanisms for networks, especially for IoT and access devices, are integrated in this amendment. Specifications for how IEEE Std 802.1X may be utilized for authentication and authorization by IEEE 1901 networks are provided in this amendment.

IEEE/IEC 80005-1a-2021

The working group JWG 28 has identified a specific need to update the IEC/IEEE 80005-1 ED2. The matter is related to the rotation of the phases for Annex C – the Cruice annex. However, the necessary modifications affect other parts of the standard, which then also needs to be aligned to keep consistency. Additionally JWG 28 has agreed that requirements for communication, such as fibre optics, should be kept outside of IEC/IEEE 80005-1, as this document should be for high voltage only.

IEEE C37.20.7-2017/Cor 1-2021

A procedure for testing and evaluating the performance of switchgear for internal arcing faults is covered. A method of identifying the capabilities of this equipment is given. Service conditions, installation, and application of equipment are also discussed. As used in this document, the term switchgear is used as a general term covering switching and interrupting devices and their combination with associated control, instrumentation, metering, protective and regulating devices, assemblies of those devices with associated interconnections, accessories, and supporting structures used primarily in conjunction with the generation, transmission, distribution, and conversion of electrical power.

IEEE C37.09-2018/Cor 1-2021

This corrigendum is to improve the current IEEE Std C37.09(TM).

IEEE 1017.1-2021

Procedures and test voltage values for factory, acceptance, and maintenance testing of electric submersible pump (ESP) cable systems are presented. This recommended practice applies to cable systems rated 3 kV through 8 kV (phase to phase) and is intended only for this special purpose cable. The intent is to provide uniform test procedures and guidelines for evaluation of the test results.

IEEE 1017.2-2021

Minimum requirements for the design, construction, manufacturing, testing, purchasing, and application of electric submersible pump (ESP) cable are presented. The cable is round or flat, with ethylene–propylene rubber insulation, nitrile jacket, ethylene–propylene diene monomer (EPDM) jacket or metallic barrier, and armor or encapsulating material. These cables are for voltages not exceeding 8 kV (phase to phase) and conductor temperatures not exceeding 140 ºC (284 ºF) for nitrile or a maximum of 232 ºC (450 ºF) for EPDM jacket or metallic barrier cable. Conductors, insulation, barrier (optional), assembly with or without jacket, armor, requirements for testing by the manufacturer, and cable…
