M/404 - Electro Magnetic compatibility

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 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.
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 for:
– 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 functional 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, energy meters.
NOTE 4 Metering, measuring and monitoring applications are explained in Annex A.

IEC 61557-12:2018 is available as IEC 61557-12:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61557-12:2018 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 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.

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). IEC 61557-12:2018 cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) PMD-A has been withdrawn due the fact these devices are now mainly covered by the IEC 62586 series of standards. b) Three categories of PMD have been created with a list of minimum required functions for each category. c) Added a new Annex A explaining the different applications linked to the relevant standards and devices, and another new Annex C about the power factor conventions.

This document applies to residual current monitors for household and similar purposes,
having rated operational voltages and a rated voltage of the monitored circuit not exceeding
440 V AC and rated currents not exceeding 125 A.
NOTE 1 The standard for residual current monitors having rated operational voltages and a rated voltage of the
monitored circuit exceeding 440 V AC is in preparation, as IEC 62020-2.
RCMs are intended to monitor the residual current of the installation and to give a warning if
the residual current between a live part and an exposed conductive part or earth exceeds a
predetermined level.
RCMs covered by this document are not intended to be used as protective devices.
RCMs detect residual currents circulating in an AC circuit (e.g. residual alternating current,
residual pulsating direct current, residual smooth direct current), whether suddenly applied or
slowly rising.
NOTE 2 RCMs for DC systems are under consideration.
This document applies to monitors performing simultaneously the functions of detection of the
residual current, of comparison of the value of this current with the residual operating current
of the device and providing the specified warning signal(s) when the residual current exceeds
this value.
RCMs supplied by internal batteries are not covered by this document.
The requirements of this document apply for standard conditions (see 7.1). Additional
requirements can be necessary for RCMs used in locations having severe environmental
conditions.
RCMs are intended for use in an environment with pollution degree 2 and overvoltage
category III. For an environment with a higher pollution degree, enclosures giving the
appropriate degree of protection are used.
RCMs in compliance with this document are suitable for use in TN, TT, and IT systems.
This document does not cover Insulation Monitoring Devices (IMDs), which are covered by the
scope of IEC 61557-8.
NOTE 3 An RCM is distinguished from an IMD in that it is passive in its monitoring function and only responds to
an unbalanced fault current in the installation being monitored. An IMD is active in its monitoring and measuring
functions in that it can measure the balanced and unbalanced insulation resistance or impedance in the installation
(see IEC 61557-8).

This part of IEC 61000 focuses on the immunity requirements and test methods for electrical
and electronic equipment, under operational conditions, with regard to:
a) repetitive slow damped oscillatory waves occurring mainly in power, control and signal
cables installed in high voltage and medium voltage (HV/MV) substations;
b) repetitive fast damped oscillatory waves occurring mainly in power, control and signal
cables installed in gas insulated substations (GIS) and in some cases also air insulated
substations (AIS) or in any installation due to high-altitude electromagnetic pulse (HEMP)
phenomena.
The object of this document is to establish a common and reproducible reference for
evaluating the immunity of electrical and electronic equipment when subjected to damped
oscillatory waves on supply, signal, control and earth ports. The test method documented in
this part of IEC 61000 describes a consistent method to assess the immunity of an equipment
or system against a defined phenomenon.
NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity
test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and
performance criteria. 1
The document defines:
– test voltage and current waveforms;
– ranges of test levels;
– test equipment;
– calibration and verification procedures of test equipment;
– test setups;
– test procedure.

This document does not apply to equipment that fall within the scope of IEC 61000-6-3. The environments encompassed by this document cover both indoor and outdoor locations. Emission requirements in the frequency range 9 kHz to 400 GHz are covered in this document and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. No measurement needs to be performed at frequencies where no requirement is specified. These requirements are considered essential to provide an adequate level of protection to radio services. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the environments included within this document. Requirements are specified for each port considered. This generic EMC emission standard is to be used where no applicable product or productfamily EMC emission standard is available.

This part of IEC 62026 applies to interfaces between low-voltage switchgear, controlgear, and
controllers (e.g. programmable controllers, personal computers, etc.).
This document does not apply to higher level industrial communication networks that have
become known as fieldbuses and are considered by IEC subcommittee 65C.
The purpose of this document is to harmonize and define rules, components and requirements
of a general nature applicable to industrial CDIs. Those features of the various CDI standards
which can be considered as general have therefore been brought together in this document.
For each CDI, two main documents are necessary to determine all requirements and tests:
a) this document, referred to as “IEC 62026-1” in the relevant CDI parts covering the various
types of CDIs;
b) the specific CDI part of the IEC 62026 series.
A specific CDI part may omit a general requirement if it is not applicable, or it may add to it if
it is inadequate in the particular case.
NOTE Product-specific requirements for products incorporating a CDI are given in the relevant product standards.
These requirements apply in addition to those given in this document.

CISPR 14-1:2016 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools and similar apparatus, whether powered by AC or DC (including a battery). Also included in the scope of this standard are separate parts of the above mentioned equipment such as motors and switching devices (e.g. power or protective relays); however, no emission requirements apply to such separate parts, unless otherwise stated in this standard. This sixth edition cancels and replaces the fifth edition published in 2005, Amendment 1:2008 and Amendment 2:2011. This edition constitutes a technical revision. The contents of the corrigendum of October 2016 and interpretation sheet 1 and 2 of May 2017 have been included in this copy.

Specifies particular requirements for the type test of newly manufactured indoor electronic ripple control receivers for the reception and interpretation of pulses of a single audio frequency superimposed on the voltage of the electricity distribution network and for the execution of the corresponding switching operations. In this system the mains frequency is generally used to synchronize the transmitter and receivers. Neither the control frequency nor the encoding are standardized in this standard.

Applies only to newly manufactured static var-hour meters of accuracy classes 2 and 3, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this standard is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.

Covers type tests for electricity metering equipment for indoor and outdoor application and to newly manufactured equipment designed to measure the electric energy on 50 Hz or 60 Hz networks, with a voltage up to 600 V. It applies to electromechanical or static meters for indoor and outdoor application consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s)

IEC 62053-24:2014 applies only to newly manufactured transformer operated static var-hour meters of accuracy classes 0,5 S, and 1 S as well as direct connected static var-hour meters of accuracy class 1, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. It uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the currents and voltages only.

CISPR 16-2-3:2016 is available as <a href="https://webstore.iec.ch/publication/25875">CISPR 16-2-3:2016 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.<br /> <br /> CISPR 16-2-3:2016 specifies the methods of measurement of radiated disturbance phenomena in the frequency range of 9 kHz to 18 GHz.

This European standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations for power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations, power autotransformers, booster transformers, substation power switchgear and power switchgear to other longitudinal and local supplies.
Filters operating at railway system voltage (for example, for harmonic suppression or power factor correction) are not included in this standard since each site has special requirements. Filters would normally have separate enclosures with separate rules for access. If electromagnetic limits are required, these will appear in the specification for the equipment.
If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators, e.g. transponder systems), then the radiated emission requirement in this standard are not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.
Emission and immunity limits are given for items of apparatus which are situated:
a)   within the boundary of a substation which delivers electric power to a railway;
b)   beside the track for the purpose of controlling or regulating the railway power supply, including power factor correction;
c)   along the track for the purpose of supplying electrical power to the railway other than by means of the conductors used for contact current collection, and associated return conductors. Included are high voltage feeder systems within the boundary of the railway which supply substations at which the voltage is reduced to the railway system voltage;
d)    beside the track for controlling or regulating electric power supplies to ancillary railway uses. This category includes power supplies to marshalling yards, maintenance depots and stations;
e)    various other non-traction power supplies from railway sources which are shared with railway traction.
The immunity levels given in this standard apply for:
-   vital equipment such as protection devices;
-   equipment having connections to the traction power conductors;
-   apparatus inside the 3 m zone;
-   ports of apparatus inside the 10 m zone with connection inside the 3 m zone;
-   ports of apparatus inside the 10 m zone with cable length > 30 m.
Apparatus and systems which are in an environment which can be described as residential, commercial or light industry, even when placed within the physical boundary of the railway substation, shall comply with EN 61000 6 1:2007 for immunity and EN 61000 6 3:2007 for emission requirements.
Excluded from the immunity requirements of this standard is power supply apparatus which is intrinsically immune to the tests defined in Tables 1 to 6.
NOTE   An example is an 18 MVA 230 kV to 25 kV power supply transformer.
These specific provisions are to be used in conjunction with the general provisions in EN 50121 1.
This part of the standard covers requirements for both apparatus and fixed installations. The sections for fixed installations are not relevant for CE marking.

Specifies general requirements for the type test of newly manufactured indoor tariff and load control equipment, like electronic ripple control receivers and time switches that are used to control electrical loads, multi-tariff registers and maximum demand indicator devices.

Applies only to newly manufactured static watt-hour meters of accuracy classes 0,2 S and 0,5 S, for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only.
