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 liasing 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 International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61822 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
97/86/FDIS 97/90/RVD
Full 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 3.
The committee has decided that the contents of this publication will remain unchanged until
2006. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

ELECTRICAL INSTALLATIONS FOR LIGHTING

AND BEACONING OF AERODROMES –
CONSTANT CURRENT REGULATORS
1 Scope
This International Standard specifies the requirements for a Constant Current Regulator (CCR)

having a nominal output of 6,6 A for use in an aeronautical ground lighting constant current
series circuit. However CCRs may be manufactured which have a different power rating (kVA)
and current steps than those specified in this standard in order to be used on existing circuits.
This standard shall be applied where appropriate for these CCRs.

3.3
contractor
organisation or person(s) given a written order to provide a service or undertake specified work

3.4

electrical equipment
anything used, intended to be used or installed for use, to generate, provide, transmit,
transform, rectify, convert, conduct, distribute, control, store, measure or use electrical energy
3.6
injury
death or personnel injury from electric shock, electric burn, electrical explosion or arcing, or
from fire or explosion initiated by electrical energy, where any such death or injury is
associated with the generation, provision, transmission, transformation, rectification,
conversion, conduction, distribution, control, storage, measurement or use of electrical energy
3.7
isolate
to disconnect and separate electrical equipment from the normal source(s) of electrical energy
in such a way that the disconnection and separation is secure
3.8
live
electrically connected to a source of electricity or having acquired a charge by other means
3.9
work/working (on electrical equipment)
installing, dismantling, assembling, maintaining or repairing of electrical equipment
4 Classification
4.1 Output current
The CCR shall produce a maximum rated r.m.s. current output of 6,6 A and a minimum rated
r.m.s. current output of 1,8 A.
4.2 Current steps
CCRs shall be classified according to the number of output current steps available, as follows:
style 1 3 current steps;
style 2 5 current steps.
Each step shall have a single adjustment over the full range specified in 4.1.
NOTE An additional low current step(s) for non-illumination purposes may be offered as an option (see5.7.6).
Each style CCR can be configured to operate with a reduced number of current steps.
