IEC 61822 pdf download – Electrical installations for lighting and beaconing of aerodromes – Constant current regulators
1scope
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 currentseries 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.

3Terms and definitions
For the purposes of this International Standard, the following definitions developed to beincluded in international standards relating to airport/aerodrome visual aids apply
3.1
aeronautical ground lighting(AGL) constant current series circuit
apparatus configured as an electrical circuit designed to produce and operate with a constantcurrent,independent of variations in the load,in order to provide a specified light for aero-nautical purposes
3.2
constant current regulator (ccR)
apparatus which produces a current output at a constant r.m.s. value independent of variationsin the constant current series circuit load, input voltage and service conditions as specified
3.3
contractor
organisation or person(s) given a written order to provide a service or undertake specified work
3.4
earthed
connected to the ground in such a manner as to ensure at all times an immediate discharge ofelectrical energy to reduce the danger of equipment damage or personnel injury
3.5
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,orfrom fire or explosion initiated by electrical energy, where any such death or injury isassociated 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 energyin 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/w orking (on electrical equipment)
installing, dismantling, assembling,maintaining or repairing of electrical equipment
4Classification
4.1output current
The CCR shall produce a maximum rated r.m.s. current output of 6,6 A and a minimum ratedr.m.s.current output of 1,8 A.
4.2current steps
CCRs shall be classified according to the number of output current steps available,as follows:
style 13 current steps;
style 25 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-llumination 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.
