ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-5: Generic standards – Immunity for power station
and substation environments
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 co-operation on all questions concerning standardization 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 Organization
for Standardization (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 and are 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 and 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 technical specification may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In excep-
tional circumstances, a technical committee may propose the publication of a technical
specification when
 the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
 the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
IEC 61000-6-5, which is a technical specification, has been prepared by technical com-
mittee 77: Electromagnetic compatibility.
The text of this technical specification is based on the following documents:
Enquiry draft Report on voting
77/227/CDV 77/232/RVC
Full information on the voting for the approval of this technical specification 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
 transformed into an International Standard;
 reconfirmed;
 withdrawn;
 replaced by a revised edition, or
 amended.

INTRODUCTION
IEC 61000 series 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 the 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 6: Generic standards
Part 9: Miscellaneous
Each part is further subdivided into sections which are to be published either as International
Standards or as technical specifications 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: 61000-6-1).
These standards, specifications and reports will be published in chronological order and
numbered accordingly.
This technical specification deals with the electromagnetic compatibility (EMC) of apparatus
used by Electricity Utilities in the generation, transmission and distribution of electricity and
related telecommunication systems. It is intended to assist Electricity Utilities in the
procurement of electronic equipment and systems.
Several EMC product standards have been published by technical committees dealing with
different application areas relevant for Electricity Utilities: switchgear and controlgear (TC 17),
power system control and associated communications (TC 57), industrial-process
measurement and control – system aspects (SC 65A), measuring relays and protection
equipment (TC 95), etc. The requirements specified in these product standards represent only
a part of the electromagnetic environment typical of power stations and substations.

TS 61000-6-5 © IEC:2001 – 11 –
Likewise, the generic immunity standard for industrial environments prepared by IEC and
CENELEC is considered by the Electricity Utilities to be not sufficient to cover the relevant
electromagnetic phenomena of the electrical plants and to give detailed acceptance criteria for
testing apparatus.
In the past, the different Utilities have prepared their own specifications. Unfortunately, these
specifications are not homogeneous; therefore the equipment manufacturers may have to apply
different tests or test levels, with consequent increase of the costs of the equipment.
Based on a common action among many Utilities, in 1994 the UNIPEDE set up a Task Force
within the Standardisation Specific Committee with the task to define unified EMC requirements
for automation and control apparatus used in power stations and substations.
As a result of this activity, the UNIPEDE Guide “Automation and control apparatus for
generating stations and substations – Electromagnetic Compatibility – Immunity
Requirements“, was published in 1995 with the reference code 23005Ren9523.
This technical specification is based on the UNIPEDE Guide above, and is intended to be
considered as a supplement to the Generic Immunity Standards, with additional tests and
acceptance criteria relevant to the special environmental conditions encountered in power
stations and substations. This technical specification should be considered as a basic
document for the preparation or revision of any EMC standard refering to specific products
used by Electrical Utilities in power stations and substations.
The review of this technical specification will be carried out not later than three years after its
publication, with the options of either extension for a further three years or conversion to an
International Standard or withdrawal.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-5: Generic standards – Immunity for power station
and substation environments
1 Scope
This technical specification sets immunity requirements for apparatus intended for use by
Electricity Utilities in the generation, transmission and distribution of electricity and related
telecommunication systems.
The locations covered are the power stations and the substations where apparatus of
Electricity Utilities are installed.
Immunity requirements are given for the frequency range 0 Hz to 400 GHz, but only in respect
of electromagnetic phenomena for which detailed test procedures, test instrumentation and test
set-up are given in existing IEC basic standards.
The immunity requirements are suitable for satisfying the particular needs related to the
functions and tasks of equipment and systems, for which reliable operation is required under
actual electromagnetic conditions; in this respect, this technical specification establishes
performance criteria for the different functional requirements.
Different requirements are given for equipment to be installed in power stations and
substations. In special cases, situations will arise where the level of electromagnetic
disturbances may exceed the levels specified in this technical specification; in these instances,
special mitigation measures should be adopted.
Non-electronic high voltage and power equipment (primary system) are excluded from the
scope of this technical specification.
This technical specification does not specify safety requirements for equip
