32、(IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addi
33、tion to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interes
34、ted in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance wit
35、h conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested I
36、EC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for
37、 the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between
38、any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of confor
39、mity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and member
40、s of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or
41、any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may
42、 be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62974-1 has been prepared by IEC technical committee 85: Measuring equipment for electrical and electromagnetic quantities. The text of this standard is based
43、 on the following documents: FDIS Report on voting 85/587/FDIS 85/589/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2

46、 IEC 62974-1:2017 IEC 2017 INTRODUCTION The use of electrical energy needs to be optimised worldwide to ensure more efficient use of available energy sources, for enhanced competitiveness, and for reducing greenhouse gas emissions and other related environmental impacts. It implies better energy man
47、agement leading to a necessary improvement of energy performance, particularly in terms of efficiency, use and consumption. This can be summarized by the lifecycle shown in Figure 1: Figure 1 Lifecycle solutions for energy efficiency Standards such as ISO 50001, ISO 50002, ISO 50006 and IEC 60364-8-
48、1 are providing information related to this topic. What is not known cannot be changed, and what is not measured is not known. Consequently, there is an increasing need to measure energy within the installations in order to: monitor performance indicators or to monitor energy baselines, or compare e
49、nergy performance between baseline period and reporting period as described in ISO 50006. Measurements can be collected by employees at a defined frequency, provided absences are accounted for (vacation, off sick, etc.), provided the measurements are relevant (number of measurement points to collect) and provided measurements can be relatively coherent (synchronism). This is why more and more devices
