(Main)Electromagnetic compatibility (EMC) - Part 6-5: Generic standards - Immunity for equipment used in power station and substation environments
Electromagnetic compatibility (EMC) - Part 6-5: Generic standards - Immunity for equipment used in power station and substation environments
This part of IEC 61000 specifies EMC immunity requirements which apply to electrical and
electronic equipment intended for use in power stations and substations, as described below.
Immunity requirements for electromagnetic phenomena with spectral contributions in the
frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies
or for phenomena where no requirements are specified.
This international standard sets immunity test requirements for equipment intended for use in
the generation, transmission and distribution of electricity and related telecommunication
systems. The electromagnetic environments encompassed by this standard are those which
exist at locations
• in power stations, and
• in high and medium voltage substations.
Installations to generate or convert into electrical power inside industrial facilities are also
covered by this standard as long as they, at their primary electrical connection, cannot be
directly connected to the LV power network, e.g. where the generator output voltage is
medium voltage or higher. Power installations that directly provide power into the low voltage
network (such as photovoltaic cells or combined heat power systems in private houses) are
not covered by this standard.
NOTE 1 In general, power stations comprise installations which are mainly built to convert some kind of primary
energy into electrical energy. Moreover, these power stations are connected to the medium or high voltage power
system directly or via a step-up transformer.
The object of this standard is to define immunity test requirements for equipment defined in
the scope in relation to continuous and transient, conducted and radiated disturbances,
including electrostatic discharges.
The immunity test requirements are given on a port-by-port basis, and selected according to
the location, with differentiated levels for equipment to be installed in power stations or
substations. In special cases, situations will arise where the level of electromagnetic
disturbances may exceed the levels specified in this standard; in these instances, special
mitigation measures should be adopted.
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
realistic electromagnetic conditions; in this respect, this standard establishes performance
criteria for different functional requirements.
This generic EMC immunity standard is applicable if no relevant dedicated product or productfamily
EMC immunity standard exists. According to IEC Guide 107, this generic standard
should be considered for the preparation or revision of any EMC standard referring to specific
products used in power stations and substations.Non-electronic high voltage and power equipment (primary system) are excluded from the
scope of this standard.
Emission requirements are not within the scope of this standard and are covered by relevant
product or product-family standards
Elektromagnetische Verträglichkeit (EMV) - Teil 6-5: Fachgrundnormen – Störfestigkeit von Betriebsmitteln, Geräten und Einrichtungen, die im Bereich von Kraftwerken und Schaltstationen verwendet werden
Compatibilité électromagnétique (CEM) - Partie 6-5: Normes génériques - Immunité pour les environnements de centrales électriques et de postes
L'IEC 61000-6-5:2015 spécifie les exigences en matière d'immunité CEM qui s'appliquent aux appareils électriques et électroniques destinés à être utilisés dans les centrales électriques et postes. Les exigences en matière d'immunité pour les phénomènes électromagnétiques avec des contributions spectrales dans la plage de fréquences comprise entre 0 Hz et 400 GHz sont couvertes. Cette édition annule et remplace la première édition de l'IEC TS 61000-6-5 parue en 2001. Cette édition constitue une révision technique.
Elektromagnetna združljivost (EMC) - 6-5. del: Osnovni standardi - Odpornost opreme, ki se uporablja v okoljih elektrarn in postaj
Ta del standarda IEC 61000 določa zahteve glede odpornosti proti elektromagnetnim motnjam, ki se uporabljajo za električne in elektronske naprave, namenjene za uporabo v elektrarnah in razdelilnih postajah, kot so opisane spodaj. Zajete so zahteve glede odpornosti za elektromagnetne pojave s spektralno porazdelitvijo v frekvenčnem razponu od 0 Hz do 400 GHz. Za frekvence ali pojave, za katere ni določenih zahtev, ni treba opraviti preskusov.
Ta mednarodni standard določa zahteve za preskušanje odpornosti za opremo, namenjeno za uporabo pri proizvodnji, prenosu in distribuciji elektrike, ter povezane telekomunikacijske sisteme. Elektromagnetna okolja, zajeta v tem standardu, obstajajo na lokacijah
• v elektrarnah in
• v visoko- in srednjenapetostnih razdelilnih postajah.
Ta standard zajema tudi naprave za proizvodnjo električne energije ali pretvorbo v električno energijo v industrijskih obratih, v kolikor jih na primarnem električnem priključku ni mogoče priključiti neposredno na nizkonapetostno omrežje, npr. kjer je izhodna napetost generatorja srednja ali visoka. Ta standard ne zajema elektroenergetskih naprav, ki neposredno zagotavljajo elektriko v nizkonapetostno omrežje (kot so fotonapetostne celice ali postaje za soproizvodnjo toplote in električne energije v zasebnih domovih).
OPOMBA 1: V splošnem elektrarne vključujejo naprave, katerih primarni namen je pretvorba neke vrste primarne energije v električno energijo. Poleg tega so te elektrarne neposredno ali prek avtotransformatorja povezane s srednje- ali visokonapetostnim električnim sistemom.
Cilj tega standarda je opredeliti zahteve glede preskusa odpornosti za opremo, ki je opredeljena za to področje uporabe, v zvezi z neprekinjenimi in začasnimi ter vodenimi in sevanimi motnjami elektromagnetnega sevanja, vključno z elektrostatičnimi razelektritvami. Zahteve glede preskusa odpornosti so podane na osnovi vsakega priključka posebej in izbrane v skladu z
lokacijo, pri čemer se v elektrarnah in razdelilnih postajah namestijo različne stopnje opreme. V posebnih primerih se pojavijo situacije, v katerih stopnja elektromagnetnih motenj presega ravni, navedene v tem standardu; v teh primerih je treba upoštevati posebne ukrepe za ublažitev.
Zahteve glede odpornosti so primerne za izpolnjevanje določenih potreb, povezanih s funkcijami in opravili opreme in sistemov, za katere je potrebno zanesljivo delovanje v realističnih elektromagnetnih pogojih; v zvezi s tem ta standard določa kriterije uspešnosti za različne funkcionalne zahteve.
Ta generični standard o odpornosti proti elektromagnetnim motnjam se uporablja, če ne obstaja ustrezen poseben standard o odpornosti proti elektromagnetnim motnjam za izdelek ali družino izdelkov. Glede na vodilo IEC Guide 107 je treba ta generični standard uporabljati pri pripravi ali reviziji vseh standardov o elektromagnetni združljivosti, ki se nanašajo na določene izdelke, uporabljene v elektrarnah ali razdelilnih postajah. Neelektronska visokonapetostna in električna oprema (primarni sistem) je izključena iz področja uporabe tega standarda. Zahteve glede oddajanja motenj ne spadajo v področje uporabe tega standarda in jih zajemajo ustrezni standardi za izdelek ali družino izdelkov.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-5: Generic standards – Immunity for equipment used
in power station and substation environment
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.

The requirements specified in these product standards consider product-specific aspects only.
It is the task of this generic standard IEC 61000-6-5 to specify a set of essential requirements,
test procedures and generalized performance criteria applicable to such products or systems
operating in this electromagnetic environment.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-5: Generic standards – Immunity for equipment used
in power station and substation environment
1 Scope and object
This part of IEC 61000 specifies EMC immunity requirements which apply to electrical and
electronic equipment intended for use in power stations and substations, as described below.
Immunity requirements for electromagnetic phenomena with spectral contributions in the
frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies
or for phenomena where no requirements are specified.
This international standard sets immunity test requirements for equipment intended for use in
the generation, transmission and distribution of electricity and related telecommunication
systems. The electromagnetic environments encompassed by this standard are those which
exist at locations
• in power stations, and
• in high and medium voltage substations.
Installations to generate or convert into electrical power inside industrial facilities are also
covered by this standard as long as they, at their primary electrical connection, cannot be
directly connected to the LV power network, e.g. where the generator output voltage is
medium voltage or higher. Power installations that directly provide power into the low voltage
network (such as photovoltaic cells or combined heat power systems in private houses) are
not covered by this standard.
NOTE 1 In general, power stations comprise installations which are mainly built to convert some kind of primary
energy into electrical energy. Moreover, these power stations are connected to the medium or high voltage power
system directly or via a step-up transformer.
The object of this standard is to define immunity test requirements for equipment defined in
the scope in relation to continuous and transient, conducted and radiated disturbances,
including electrostatic discharges.
The immunity test requirements are given on a port-by-port basis, and selected according to
the location, with differentiated levels for equipment to be installed in power stations or
substations. In special cases, situations will arise where the level of electromagnetic
disturbances may exceed the levels specified in this standard; in these instances, special
mitigation measures should be adopted.
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
realistic electromagnetic conditions; in this respect, this standard establishes performance
criteria for different functional requirements.
This generic EMC immunity standard is applicable if no relevant dedicated product or product-
family EMC immunity standard exists. According to IEC Guide 107, this generic standard
should be considered for the preparation or revision of any EMC standard referring to specific
products used in power stations and substations.
NOTE 2 Product standards covering EMC aspects for equipment to be used in power stations or substations are
for example IEC 62271-1 (switchgear and controlgear), IEC 60255-26 (measuring relays and protection equipment)
or IEC 62236-5 (fixed power supply installations and apparatus for railway applications).

Non-electronic high voltage and power equipment (primary system) are excluded from the
scope of this standard.
Emission requirements are not within the scope of this standard and are covered by relevant
product or product-family standards.
NOTE 3 Where no dedicated product or product family standard covering emission requirements exists, the
generic standard IEC 61000-6-4 applies.
