17、TRANSFORMERS 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 stand
18、ardization 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
19、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 organizati
20、ons. 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
21、 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
22、 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 i
23、ts 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 id
24、entifying 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: FDIS Report on voting 97/94/FDIS 97/95/RVD Full
25、 information on the voting for the approval of this standard 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 2. The committee has decided that the contents of this publication will remain unchanged u
26、ntil 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 LIGHTING AND BEACONING OF AERODROMES AGL SERIES TRANSFORMERS 1 Scope This standard specifies the characteristics of aeronautical ground
27、lighting series transformers (AGLST) used in aeronautical ground lighting for 6,6 A series circuits, at a service voltage of up 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) fro
28、m their secondary circuits. The AGL series transformers provide continuity of the series circuit in the event of a loss of the load on the transformer, and electrical isolation between the primary circuit supplied by a constant current regulator, and the secondary circuit connected to the load under
29、 conditions defined in this standard. An AGL series transformer is be able to withstand a permanent short or open-circuit secondary series circuit. Specifications for similar series transformers intended for any primary or secondary currents other than 6,6 A, or to supply alternative voltages, const
30、ant power, reactive loads, etc., are not included in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced doc
