Medium Voltage AC Adjustable Speed Drives
This Practice describes additions, changes, and deletions that have been made to IEEE 1566-2015. In addition, decisions that have been made regarding options offered by IEEE 1566-2015 are also described.
New Practice
Liquid Immersed Power Transformers (IEC)
This Practice describes the requirements for design, manufacture, inspection, testing, and shipping of three-phase and single-phase liquid-immersed power transformers in accordance with applicable International Electrotechnical Commission (IEC) standards.
New Practice
Design and Fabrication of Metal-Enclosed Nonsegregated-Phase Bus-Duct Assemblies
This Practice describes requirements for design, fabrication, inspection, and testing of metal-enclosed, self-cooled, nonsegregated-phase bus duct assemblies for use on systems operating at 34.5 kV and below, and suitable for indoor and outdoor applications.
Complete Revision
Design and Fabrication of Medium-Voltage Gas-Insulated Switchgear up to 52kV
This Practice covers the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for gas insulated switchgear containing gas-insulated buses, power circuit breakers, control, instrumentation, and metering for installation in unclassified areas. This Practice also covers remote monitoring and control requirements.
New Practice
Arc Flash Hazard Analysis Guideline
This Practice provides information for performing an arc flash hazard analysis as required by NFPA 70E and IEEE C2. It provides guidance on the determination of the arc flash boundary, the incident energy at the working distance, and arc flash pressure. This information can be used to mitigate the possibility of an arc flash event through engineering controls or in the proper selection of personal protective equipment (PPE).Arc flash risk assessment, as required by NFPA 70E, is outside the scope of this document.
Technical Revision
Design and Fabrication of Medium-Voltage Gas Insulated Switchgear up to 52kV (IEC)
This Practice covers the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for gas insulated switchgear containing gas-insulated buses, power circuit breakers, control, instrumentation, and metering for installation in unclassified areas. This Practice also covers remote monitoring and control requirements.
New Practice
Leak Testing of Piping Systems
This Practice provides leak-testing procedures, practices, and precautions for piping designed and constructed to ASME B31.3 Process Piping, hereinafter referred to as the Code, and describes requirements that are in addition to those of the Code.
Complete Revision
Dry Type Power Transformers
This Practice contains the minimum requirements for design, manufacture, inspection, testing, and shipping of air cooled dry type power transformers with ratings up to and including 30,000 kVA with voltage ratings 34.5kV and below.
Technical Correction
Liquid Containment Pits Design Guide
This Practice provides design considerations to engineers designing liquid containment pits, holding ponds, and basins. It includes civil, geotechnical, and hydrological engineering aspects, specifically addressing pits lined with geomembranes.
