High-voltage switchgear and controlgear -- Part 200: AC metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV
Specifies requirements for factory-assembled metal-enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. This standard defines several types of metal enclosed switchgear and controlgear which differ due to - the consequences on network service continuity in case of maintenance on the switchgear and controlgear; - the need and convenience of maintenance of the equipment. For metal-enclosed switchgear and controlgear containing gas-filled compartments, the design pressure is limited to a maximum of 300 kPa (relative pressure). Metal-enclosed switchgear and controlgear for special use, for example, in flammable atmospheres, in mines or on board ships, may be subject to additional requirements. Components contained in metal-enclosed switchgear and controlgear are to be designed and tested in accordance with their various relevant standards. This standard supplements the standards for the individual components regarding their installation in switchgear and controlgear assemblies. This standard does not preclude that other equipment may be included in the same enclosure. In such a case, any possible influence of that equipment on the switchgear and controlgear is to be taken into account. This first edition of EN 62271-200 cancels and replaces the third edition of EN 60298, published in 1990, and constitutes a technical revision. Significant technical changes from the third edition of EN 60298 are as follows: This revised document has been basically changed to be updated to today's use of high- voltage switchgear and controlgear up to 52 kV. The main changes are: new definitions and classification of equipment, introduction of internal arc classes (IAC) and its testing. This standard is to be rea

Appareillage à haute tension -- Partie 200: Appareillage sous enveloppe métallique pour courant alternatif de tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV
Spécifie les exigences pour l'appareillage préfabriqué sous enveloppe métallique pour courant alternatif, prévu pour être installé à l'intérieur et à l'extérieur, pour des tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV et pour des fréquences de service inférieures ou égales à 60 Hz. Les enveloppes peuvent contenir des composants fixes et amovibles et peuvent être remplies de fluide (liquide ou gaz) pour assurer l'isolation. Cette norme définit plusieurs types d'appareillage sous enveloppe métallique qui diffèrent par - les conséquences sur la continuité de service en cas de maintenance sur l'appareillage; - les besoins et la facilité de maintenance des équipements. Pour l'appareillage sous enveloppe métallique comprenant des compartiments à remplissage de gaz, la pression effective de calcul est limitée à un maximum de 300 kPa (pression relative). L'appareillage sous enveloppe métallique destiné à une utilisation spéciale, par exemple pour atmosphères inflammables, dans les mines ou à bord des navires, peut faire l'objet d'exigences complémentaires. Il faut que les matériels compris dans l'appareillage sous enveloppe métallique soient conçus et essayés suivant leurs différentes normes respectives. La présente norme complète les normes des matériels spécifiques, concernant leur installation dans les ensembles d'appareillage. Cette norme n'interdit pas que d'autres équipements puissent être incorporés dans la même enveloppe. Dans de tels cas, il faut tenir compte de l'influence de ces équipements sur l'appareillage. Cette première édition de la EN 62271-200 annule et remplace la troisième édition de la EN 60298 parue en 1990 dont elle constitue une révision technique.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62271-200 has been prepared by subcommittee 17C: High-voltage
switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
controlgear.
This first edition of IEC 62271-200 cancels and replaces the third edition of IEC 60298,
published in 1990, and constitutes a technical revision.
Significant technical changes from the third edition of IEC 60298 are as follows:
This revised document has been basically changed to be updated to today’s use of high-
voltage switchgear and controlgear up to 52 kV. The main changes are: new definitions and
classification of equipment, introduction of internal arc classes (IAC) and its testing.

COMMON NUMBERING OF IEC 62271 PUBLICATIONS FALLING UNDER
THE RESPONSIBILITY OF SUBCOMMITTEES SC 17A AND SC 17C
In accordance with the decision taken at the joint SC 17A/SC 17C meeting in Frankfurt, June
1998 (item 20.7 of 17A/535/RM), a common numbering system has been established for the
publications falling under the responsibility of SC 17A and SC 17C. IEC 62271 – High-voltage
switchgear and controlgear is the publication number and main title element for the common
publications.
The numbering of these publications will apply the following principle.
a) Common standards prepared by SC 17A and SC 17C will start with IEC 62271-1.
b) Standards of SC 17A will start with IEC 62271-100.
c) Standards of SC 17C will start with number IEC 62271-200.
d) Publications prepared by SC 17A and SC 17C will start with number IEC 62271-300.
The table below relates the new numbers to the old numbers. The parts numbered (xxx) will be
given a final number pending the decision to publish the revised publication as standard or
technical report.
