Abstract
IEC TS 63191:2023 specifies recommendations about power quality measurement and assessment within installations.
This document outlines the various phases needed for the establishment of a demand-side power quality measurement plan for buildings and industry installations.
Such a power quality measurement plan will enable the optimization of the energy availability and efficiency, improve the assets lifetime and facilitate the resolutions of power quality problems. A power quality measurement plan encompasses the following phases:
• definition of the context, objectives and constraints;
• assessment of the initial power quality situation;
• definition of an action plan for the improvement of the power quality situation;
• implementation of the power quality measuring system;
• exploitation of the measurement system for the improvement of the power quality situation;
• maintenance of the measurement system.
This document will also help facility managers tailor their measurement plan to the specific needs of the electrical system under their control. It addresses all the disturbances present in such networks, but does not cover the disturbances present in public electrical distribution networks (supply side) as they are governed by specific documents such as EN 50160 and IEC TS 62749.
IEC TS 63191:2023 cancels and replaces IEC TR 63191, published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) a new informative Annex A describing a tool to report the ability to assess the power quality of an electrical installation.
