(Amendment)Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC - Equipment for testing, measuring or monitoring of protective measures - Part 12: Power metering and monitoring devices (PMD)
Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC - Equipment for testing, measuring or monitoring of protective measures - Part 12: Power metering and monitoring devices (PMD)
This part of IEC 61557 specifies requirements for power metering and monitoring devices (PMD) that measure and monitor the electrical quantities within electrical distribution systems, and optionally other external signals. These requirements also defin the performance of PMD in single- and three-phace AC or DC systems having rated voltages up to 1000 V AC or up to 1500 V DC. These devices are fixed or portable. They are intended to be used indoors and/or outdoors. Power metering and monitoring devices (PMD), as defined in this document, give additional safety information, which aids the verification of the installation and enhances the performance of the distribution systems. Additionally, this document specifies requirements for measurement functions dedicated to metering and monitoring of electrical parameters called power metering and monitoring function (PMF) which can be embedded in equipment (EMPF) that is not classified as PMD and for which the main function is not power metering and monitoring. Requirements for power metering and monitoring function (PMF) and additional requirements for equipments embedding power metering and monitoring function (EPMF) are described in Annex H. The power metering and monitoring devices (PMD) for electrical parameters described in this document are used for general industrial and commercial applications. This document does not address functional safety and cyber security aspects. This document is not applicable to: - electricity metering equipment that complies with IEC 62053-21, IEC 62053-22, IEC 62053-23 and IEC 62053-24. Nevertheless, uncertainties defined in this document for active and reactive energy measurement are derived from those defined in IEC 62053 (all parts); - the measurement and monitoring of electrical parameters defined in IEC 61557-2 to IEC 61557-9 and IEC 61557-13 or in IEC 62020; - power quality instrument (PQI) according IEC 62586 (all parts); - devices covered by IEC 60051 (all parts) (direct acting analogue electrical measuring instrument). Note 1 Generally such types of devices are used in the following applications or for the following general needs: - energy management inside the installation, such as facilitating the implementation of documents such as ISO 50001 and IEC 60364-8-1; - monitoring and/or measurement of electrical parameters; - measurement and/or monitoring of the quality of energy inside commercial/industrial installations. Note 2 A measuring and monitoring device of electrical parameters usually consists of several functional modules. All or some of the functional modules are combined in one device. Examples of fuctnional modules are: - measurement and monitoring of several electrical parameters simultaneously; - energy measurement and/or monitoring, as well as sometimes compliance with aspects of building regulations; - alarms functions; - demand side quality (current and voltage harmonics, over/under voltages, voltage dips and swells, etc.). Note 3 PMD are historically called power meter, power monitor, power monitor device, power energy monitoring device, power analyser, multifunction meter, measuring multifunction equipment, energe meters. Note 4 Metering, measuring and monitoring applications are explained in Annex A.

FOREWORD
1) The International Electrotechnical Commission (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 addition 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 interested 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 with 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 IEC 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 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
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 conformity. 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
members 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 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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

1 Scope
Replace the existing text of this clause by the following new text:
This part of IEC 61557 specifies requirements for power metering and monitoring devices (PMD)
that measure and monitor the electrical quantities within electrical distribution systems, and
optionally other external signals. These requirements also define the performance of PMD in
single- and three-phase AC or DC systems having rated voltages up to 1 000 V AC or up to
1 500 V DC.
These devices are fixed or portable. They are intended to be used indoors and/or outdoors.
Power metering and monitoring devices (PMD), as defined in this document, give additional
safety information, which aids the verification of the installation and enhances the performance
of the distribution systems.
Additionally, this document specifies requirements for measurement functions dedicated to
metering and monitoring of electrical parameters called power metering and monitoring function
(PMF) which can be embedded in equipment (EPMF) that is not classified as PMD and for which
the main function is not power metering and monitoring.
Requirements for power metering and monitoring function (PMF) and additional requirements
for equipment embedding power metering and monitoring function (EPMF) are described in
Annex H.
The power metering and monitoring devices (PMD) for electrical parameters described in this
document are used for general industrial and commercial applications.
The power metering and monitoring devices (PMD) can be associated with sensing devices
such as but not limited to instruments transformers compliant to IEC 61869 series of standards
or with transducers compliant to IEC 60688.
This document does not address functional safety and cyber security aspects.
