8 FOREWORD
9 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
10 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
11 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
12 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
13 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
14 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
15 in the subject dealt with may participate in this preparatory work. International, governmental and non -
16 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
17 with the International Organization for Standardization (ISO) in accordance with conditions determined by
18 agreement between the two organizations.
19 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
20 consensus of opinion on the relevant subjects since each technical committee has representation from all
21 interested IEC National Committees.
22 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
23 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
24 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
25 misinterpretation by any end user.
26 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
27 transparently to the maximum extent possible in their national and regional publications. Any divergence
28 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
29 the latter.
30 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
31 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
32 services carried out by independent certification bodies.
33 6) All users should ensure that they have the latest edition of this publication.
34 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
35 members of its technical committees and IEC National Committees for any personal injury, property damage or
36 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
37 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
38 Publications.
39 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
40 indispensable for the correct application of this publication.
41 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
42 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
43 IEC 63297 has been prepared by IEC technical committee 85: Measuring equipment for
44 electrical and electromagnetic quantities.
45 The text of this International Standard is based on the following documents:

53 The committee has decided that the contents of this publication will remain unchanged until
54 the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
55 related to the specific publication. At this date, the publication will be
56 • reconfirmed,

58 • amended, or
59 • revised.

63 INTRODUCTION
64 Non-intrusive load monitoring (NILM), or non-intrusive appliance and load monitoring (NIALM),
65 is a process for providing estimated energy usage, e.g. by type of use (heating, cooling, etc.)
66 or type of appliance (microwave, etc.) based on load signatures at a single point in the
67 installation.
68 NILM systems can be used to survey the specific uses of electrical power in homes, buildings
69 or industrial areas (see Figure 1).
71 Figure 1 – Principle of non-intrusive load monitoring (NILM)
72 At the moment, NILM systems are essentially used in AC distribution networks, but DC
73 networks are not excluded.

77 LOAD MONITORING (NILM) SYSTEMS
81 1 Scope
82 This International Standard provides a classification of NILM sensing devices for use in NILM
83 systems, according to the state of the art of NILM technologies.
84 The classification of NILM analytics and NILM systems, as well as performance indicators for
85 NILM systems, can be considered in the future.
86 NILM systems produce estimated disaggregation into energy usages. When accurate
87 measurement and analysis of energy consumption and/or other electrical parameters is
88 needed (e.g. for monitoring the electrical installation), systems based on standardized
89 measuring devices (e.g. PMD, PQI or meters) are used.
90 NOTE Standardized measuring devices have guaranteed accuracy over a specified range and have limited
