Overview

IEC 61800-3:2017 - "Adjustable speed electrical power drive systems – Part 3: EMC requirements and specific test methods" is the International Electrotechnical Commission standard that specifies electromagnetic compatibility (EMC) requirements and test methods for adjustable speed AC and DC motor drive systems (Power Drive Systems, PDS). The third edition (also published as a Redline version showing changes versus the previous edition) is a technical revision. It covers PDSs with converter input and/or output voltages up to 35 kV AC RMS and updates both measurement setups and reporting requirements for EMC compliance.

Key updates in the 2017 edition

• Clarified requirements for the test report, particularly when alternative test methods are used.
• Introduced a more detailed test setup for radiated emission measurements and a 3 m measurement distance for small equipment.
• General updates and expansions in informative annexes (EMC techniques, low-frequency phenomena, filtering, installation rules, EMC planning).

Key Topics

• Scope and definitions for PDS installations, ports, interfaces and intended use.
• Immunity requirements: performance criteria for low-frequency disturbances (harmonics, commutation notches, voltage dips, unbalance, magnetic fields) and high-frequency disturbances (radiated and conducted immunity).
• Emission limits and measurement: procedures for low- and high-frequency emissions, conducted and radiated tests, and category-based requirements (equipment categories such as C1–C4 are addressed).
• Test methods and setup: detailed configurations for in-situ and laboratory measurements, cable arrangements, AMN/impedance usage, and the new 3 m radiated measurement distance for small equipment.
• Documentation and test reporting: mandatory content and clarity when multiple test methods are applicable.
• Informative annexes: practical guidance on harmonics, commutation notches, reactive power compensation, filtering, EMC planning for large installations, and user guidelines for managing high-frequency emissions.

Applications and Users

IEC 61800-3:2017 is essential for:

• Manufacturers of adjustable speed drives and converters who need to design products that meet EMC requirements.
• EMC test laboratories performing emission and immunity testing to international methods.
• System integrators and electrical engineers specifying drives for industrial, commercial or utility-connected installations up to 35 kV.
• Compliance officers and procurement teams requiring documented EMC performance and standardized test reports.
• Maintenance and commissioning engineers addressing EMC-related disturbances, harmonics, filtering and installation mitigation.

Practical uses include product design validation, type testing, site acceptance testing, EMC planning for complex installations (category C4), and guidance on filtering and reactive compensation to limit emissions and improve immunity.

Related Standards

IEC 61800-3 interfaces with other EMC and power quality standards (harmonic/voltage disturbance standards and test-method standards). For product compliance it is typically used alongside general EMC standards and national grid connection rules.

ADJUSTABLE SPEED ELECTRICAL POWER

DRIVE SYSTEMS –
Part 3: EMC requirements and specific test methods

1 Scope and object
This part of IEC 61800 specifies electromagnetic compatibility (EMC) requirements for power
drive systems (PDSs, defined in 3.1). These are adjustable speed AC or DC motor drives.
Requirements are stated for PDSs with converter input and/or output voltages (line-to-line
voltage), up to 35 kV AC RMS.
PDSs covered by this document are those installed in residential, commercial and industrial
locations with the exception of traction applications, and electric vehicles. PDSs may can be
connected to either industrial or public power distribution networks. Industrial networks are
supplied by a dedicated distribution transformer, which is usually adjacent to or inside the
industrial location, and supplies only industrial customers. Industrial networks can also be
supplied by their own electric generating equipment. On the other hand, PDSs can be directly
connected to low-voltage public mains networks which also supply domestic residential
premises, and in which the neutral is generally earthed (grounded).
The scope of this part of IEC 61800, related to EMC, includes a broad range of PDSs from a
few hundred watts to hundreds of megawatts. PDSs are often included in a larger system. The
system aspect is not covered by this document but guidance is provided in the informative
annexes.
The requirements have been selected so as to ensure EMC for PDSs at residential,
commercial and industrial locations. The requirements cannot, however, cover extreme cases
which may can occur with an extremely low probability. Changes in the EMC behaviour of a
PDS, as a result of fault conditions, are not taken into account.
The object of this document is to define the limits and test methods for a PDS according to its
intended use. This document includes immunity requirements and requirements for electro-
magnetic emissions.
NOTE 1 Emission can cause interference in other electronic equipment (for example radio receivers, measuring
and computing devices). Immunity is required meant to protect the equipment from continuous and transient
conducted and radiated disturbances including electrostatic discharges. The emission and immunity requirements
are balanced against each other and against the actual environment of the PDS.

This document defines the minimum EMC requirements for a PDS.
Immunity requirements are given according to the environment classification. Low-frequency
emission requirements are given according to the nature of the supply network. High-
frequency emission requirements are given according to four categories of intended use,
which cover both environment and bringing into operation.
As a product standard, this document may can be used for the assessment of PDS. It may
can also be used for the assessment of complete drive modules (CDM) or basic drive modules
(BDM) (see 3.1), which can be marketed separately.
This document contains
• conformity assessment requirements for products to be placed on the market, and

– 10 – IEC 61800-3:2017 RLV © IEC 2017

• recommended engineering practice (see 6.5) for cases where high frequency emissions

cannot be measured before the equipment is placed on the market (such PDSs are

defined in 3.2.7 as category C4).

NOTE 2 The first edition of IEC 61800-3 identified that the intended use could require engineering for putting into
service. This was done by the “restricted distribution mode”. Equipment that used to be covered by the formerly

identified under “restricted distribution mode” is now covered in the second edition by categories C2 and C4 (see

3.2).
This document is intended as a complete EMC product standard for the EMC conformity

assessment of products of categories C1, C2 and C3, when placing them on the market (see

definitions 3.2.4 to 3.2.6).
Radio frequency emission of equipment of category C4 is only assessed when it is installed in
its intended location. It is therefore treated as a fixed installation, for which this document
gives rules of engineering practice in 6.5 and Annex E, although it gives no defined emission
limits (except in case of complaint).
This document does not specify any safety requirements for the equipment such as protection
against electric shocks, insulation co-ordination and related dielectric tests, unsafe operation,
or unsafe consequences of a failure. It also does not cover safety and functional safety
implications of electromagnetic phenomena.
In special cases, when highly susceptible apparatus is being used in proximity, additional
mitigation measures may can have to be employed to reduce the electromagnetic emission
further below the specified levels or additional countermeasures may can have to be
employed to increase the immunity of the highly susceptible apparatus.
As an EMC product standard for PDSs, this document takes precedence over all aspects of
the generic standards, and no additional EMC tests are required or necessary performed. If a
PDS is included as part of equipment covered by a separate EMC product standard, the EMC
standard of the complete equipment applies.

Part 3: EMC requirements and specific test methods

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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61800-3 has been prepared by subcommittee 22G: Adjustable
speed electric drive systems incorporating semiconductor power converters, of IEC technical
committee 22: Power electronic systems and equipment.
This third edition cancels and replaces the second edition published in 2004 and
Amendment 1:2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) clarification of requirements for the test report, particularly when a number of alternative
test methods exist;
b) introduction of a more detailed test setup for radiated emission measurements, along with
the introduction of a 3 m measurement distance for small size equipment;
c) general updates in the informative annexes.

ADJUSTABLE SPEED ELECTRICAL POWER
DRIVE SYSTEMS –
Part 3: EMC requirements and specific test methods

1 Scope
This part of IEC 61800 specifies electromagnetic compatibility (EMC) requirements for power
drive systems (PDSs, defined in 3.1). These are adjustable speed AC or DC motor drives.
Requirements are stated for PDSs with converter input and/or output voltages (line-to-line
voltage), up to 35 kV AC RMS.
PDSs covered by this document are those installed in residential, commercial and industrial
locations with the exception of traction applications, and electric vehicles. PDSs can be
connected to either industrial or public power distribution networks. Industrial networks are
supplied by a dedicated distribution transformer, which is usually adjacent to or inside the
industrial location, and supplies only industrial customers. Industrial networks can also be
supplied by their own electric generating equipment. On the other hand, PDSs can be directly
connected to low-voltage public mains networks which also supply residential premises, and
in which the neutral is generally earthed (grounded).
The scope of this part of IEC 61800, related to EMC, includes a broad range of PDSs from a
few hundred watts to hundreds of megawatts. PDSs are often included in a larger system. The
system aspect is not covered by this document but guidance is provided in the informative
annexes.
The requirements have been selected so as to ensure EMC for PDSs at residential,
commercial and industrial locations. The requirements cannot, however, cover extreme cases
which can occur with an extremely low probability. Changes in the EMC behaviour of a PDS,
as a result of fault conditions, are not taken into account.
The object of this document is to define the limits and test methods for a PDS according to its
intended use. This document includes immunity requirements and requirements for electro-
magnetic emissions.
NOTE 1 Emission can cause interference in other electronic equipment (for example radio receivers, measuring
and computing devices). Immunity is meant to protect the equipment from continuous and transient conducted and
radiated disturbances including electrostatic discharges. The emission and immunity requirements are balanced
against each other and against the actual environment of the PDS.
This document defines the minimum EMC requirements for a PDS.
Immunity requirements are given according to the environment classification. Low-frequency
emission requirements are given according to the nature of the supply network. High-
frequency emission requirements are given according to four categories of intended use,
which cover both environment and bringing into operation.
As a product standard, this document can be used for the assessment of PDS. It can also be
used for the assessment of complete drive modules (CDM) or basic drive modules (BDM)
(see 3.1), which can be marketed separately.
This document contains
• conformity assessment requirements for products to be placed on the market, and

– 10 – IEC 61800-3:2017 © IEC 2017
• recommended engineering practice (see 6.5) for cases where high frequency emissions
cannot be measured before the equipment is placed on the market (such PDSs are
defined in 3.2.7 as category C4).
NOTE 2 The first edition of IEC 61800-3 identified that the intended use could require engineering for putting into
service. This was done by the “restricted distribution mode”. Equipment formerly identified under “restricted
distribution mode” is now covered by categories C2 and C4 (see 3.2).
This document is intended as a complete EMC product standard for the EMC conformity
assessment of products of categories C1, C2 and C3, when placing them on the market (see
definitions 3.2.4 to 3.2.6).
Radio frequency emission of equipment of category C4 is only assessed when it is installed in
its intended location. It is therefore treated as a fixed installation, for which this document
gives rules of engineering practice in 6.5 and Annex E, although it gives no defined emission
limits (except in case of complaint).
This document does not specify any safety requirements for the equipment such as protection
against electric shocks, insulation co-ordination and related dielectric tests, unsafe operation,
or unsafe consequences of a failure. It also does not cover safety and functional safety
implications of electromagnetic phenomena.
In special cases, when highly susceptible apparatus is being used in proximity, additional
mitigation measures can have to be employed to reduce the electromagnetic emission further
below the specified levels or additional countermeasures can have to be employed to
increase the immunity of the highly susceptible apparatus.
As an EMC product standard for PDSs, this document takes precedence over all aspects of
the generic standards, and no additional EMC tests are performed. If a PDS is included as
part of equipment covered by a separate EMC product standard, the EMC standard of the
complete equipment applies.
