FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international cooperation on all questions concerning standardisation in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. 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. The IEC collaborates closely with the International
Standardization Organization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the 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 National Committees.
3) The documents produced have the form of recommendations for international use published in the form of
standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard an the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61000-3-11 has been prepared by sub-committee 77A: Low-frequency
phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This first edition of IEC 61000-3-11 is based on the contents of IEC Technical Report
61000-3-5 which was published in 1994 and is still relevant to equipment with a rated input
current >75 A.
This standard has the status of a family product standard.
The text of this standard is based on the following documents:
FDIS Report on voting
77A/309/FDIS 77A/318/RVD
Full information on the voting for the approval of this section can be found in the report on
voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A and B are for information only.
The committee has decided that the contents of this publication will remain unchanged until
2005. At this date, the publication will be
• reconfirmed:

INTRODUCTION
IEC 61000 is published in separate parts according to the following structure:
Part 1: General
General Considerations (introduction, fundamental principles)
Definitions, terminology
Part 2: Environment
Description of the environment
Classification of the environment
Compatibility levels
Part 3: Limits
Emission limits
Immunity limits (in so far as they do not fall under the responsibility of product
committees)
Part 4: Testing and measurement techniques
Measurement techniques
Testing techniques
Part 5: Installation and mitigation guidelines
Installation guidelines
Mitigation methods and devices
Part 9: Miscellaneous
Each part is further subdivided into several parts published either as International Standards or
technical reports, some of which have already been published as sections. Others will be
published with the part number followed by a dash and a second number identifying the
subdivision (example: 61000-3-11).
The scope of this part overlaps with that of IEC 61000-3-3 in that it is also applicable to
equipment with a rated input current ≤16 A. However, it should be noted that equipment having
a rated input current ≤16 A should first be tested for conformity with IEC 61000-3-3 before
applying the evaluation techniques and measurement procedures specified in this part of
IEC 61000.
Equipment which meets the requirements of IEC 61000-3-3 is not subject to conditional
connection and therefore it is not subject to this part of IEC 61000.
The limits in this part relate to the voltage changes experienced by consumers connected at
the interface between the public supply low-voltage network and the equipment user’s
installation. Therefore, it cannot be guaranteed that the user of equipment compliant with this
standard will not experience supply disturbance within his own installation, as the impedance at
the point of connection of the equipment to the supply within the installation may have an
impedance greater than the test impedance.

Part 3-11: Limits –
Limitation of voltage changes, voltage fluctuations and flicker
in public low-voltage supply systems – Equipment with rated current

1 Scope and object
This part of IEC 61000 is concerned with the emission of voltage changes, voltage fluctuations
and flicker produced by equipment and impressed on the public low-voltage supply system.
It specifies the limits of voltage changes produced by equipment tested under specified
conditions.
This part of IEC 61000 is primarily applicable to electrical and electronic equipment having a
rated input current from 16 A up to and including 75 A, which is intended to be connected to
public low-voltage distribution systems having nominal system voltages of between 220 V and
250 V, line-to-neutral at 50 Hz, and which is subject to conditional connection.
This part of IEC 61000 is also applicable to equipment withi
