This document specifies recommendations about power quality measurement and assessment within installations.
NOTE 1 Most standards take care of power quality at the delivery point between energy providers and customers.
This document outlines the various phases needed for the establishment of a demand side power quality measurement plan for buildings and industry installations.
NOTE 2 The demand side is defined as the electrical installation, beyond the PCC (point of common coupling), which is under the jurisdiction of facility managers.
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 stages:
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 to 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.
