Installations électriques pour le balisage et l'éclairage des aérodromes - Transformateurs séries AGL

L'IEC 61823:2002 spécifie les caractéristiques des transformateurs série utilisés pour le balisage aéronautique au sol (AGLST) pour des circuits série de 6,6 A, dont la tension de service atteint 5 kV, alimentés par des régulateurs de courant constant jusqu'à 30 kVA. Les transformateurs série AGL assurent l'alimentation des feux aéronautiques de balisage ou d'autres charges (résistives) à partir de leurs circuits secondaires. Les transformateurs série AGL assurent la continuité du circuit série en cas de perte de charge sur le transformateur, et l'isolation électrique entre le circuit primaire alimenté par un régulateur de courant constant et le circuit secondaire connecté à la charge dans des conditions définies dans la présente Norme. La présente version bilingue (2016-11) correspond à la version anglaise monolingue publiée en 2002-12.

– 4 –61823  IEC:2002(E)INTERNATIONAL ELECTROTECHNICAL COMMISSION___________ELECTRICAL INSTALLATIONS FOR LIGHTINGAND BEACONING OF AERODROMES –AGL SERIES TRANSFORMERSFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment 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 subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61823 has been prepared by IEC technical committee 97:Electrical installations for lighting and beaconing of aerodromes.The text of this standard is based on the following documents:FDISReport on voting97/94/FDIS97/95/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.The committee has decided that the contents of this publication will remain unchangeduntil 2006. At this date, the publication will be•reconfirmed;•withdrawn;•replaced by a revised edition, or•amended.

61823  IEC:2002(E)– 5 –ELECTRICAL INSTALLATIONS FOR LIGHTINGAND BEACONING OF AERODROMES –AGL SERIES TRANSFORMERS1 ScopeThis standard specifies the characteristics of aeronautical ground lighting series transformers(AGLST) used in aeronautical ground lighting for 6,6 A series circuits, at a service voltage ofup to 5 kV, supplied by constant current regulators up to 30 kVA in rating.AGL series transformers provide power to airport lighting luminaires or other loads (resistive)from their secondary circuits. The AGL series transformers provide continuity of the seriescircuit in the event of a loss of the load on the transformer, and electrical isolation betweenthe primary circuit supplied by a constant current regulator, and the secondary circuitconnected to the load under conditions defined in this standard.An AGL series transformer is be able to withstand a permanent short or open-circuitsecondary series circuit.Specifications for similar series transformers intended for any primary or secondary currentsother than 6,6 A, or to supply alternative voltages, constant power, reactive loads, etc., arenot included in this standard.2 Normative referencesThe following referenced documents are indispensable for the application of this document.For dated references, only the edition cited applies.
