About This Item
IEEE P1564/D19, July 2013 is a technical document focused on voltage sag indices, helping engineers describe and compare short-duration voltage disturbances in power systems. In the context of Power, Energy and Industry Applications, it supports more consistent assessment of sag performance across components, circuits, devices, and system interfaces. The standard is useful where voltage quality affects equipment behavior, process continuity, and reliability expectations, making IEEE P1564/D19, July 2013 a practical reference for analysis and reporting.
What is IEEE P1564/D19, July 2013?
IEEE P1564/D19, July 2013 provides guidance for defining and using voltage sag indices so disturbance data can be interpreted in a more uniform way. Rather than focusing on a single device, it addresses how sag events are characterized, summarized, and communicated in power-system studies. This makes the document relevant for engineers who need a common technical basis for comparing results, evaluating performance, or documenting power quality behavior in electrical systems and related equipment environments.
Where is IEEE P1564/D19, July 2013 used?
IEEE P1564/D19, July 2013 is typically used in power quality monitoring, utility studies, industrial facility assessments, and engineering analysis of sensitive electrical loads. It may be applied when reviewing sag performance at service entrances, distribution feeders, or equipment points of common coupling. The guidance is especially relevant for systems where control devices, process equipment, or electronics can be affected by voltage dips, and where consistent sag indices help compare conditions across sites or operating periods.
Why is IEEE P1564/D19, July 2013 important?
This standard matters because voltage sag data can otherwise be difficult to compare from one study to another. IEEE P1564/D19, July 2013 supports more consistent reporting, which can improve design decisions, procurement reviews, and troubleshooting of power quality issues. Clear sag indices also help reduce ambiguity in compliance discussions and performance evaluations, especially when organizations need to document disturbance levels, assess equipment resilience, or compare mitigation options across electrical installations.
