IEC 61820-1:2019 pdf download.Electrical installations for aeronautical ground lighting at aerodromes – Part 1: Fundamental principles
1 Scope
This part of IEC 61 820 covers principles of design and installation requirements for AGL systems including control, monitoring and transformation of energy, the cables and any electrical component utilized to produce the light intended to be used as a visual aid for air and ground navigation. This document defines in general the fundamental principles to provide safe, reliable and efficient operation of AGL systems independent of the particular system design. Where certain aspects of design are specific to a particular type of system (e.g. series-circuit), these are supplemented in the applicable part. NOTE Local / national regulations can be different from the provisions of this document.
