Airport Lighting

Isolating transformer are used in Air Field Lighting system and provide isolation between the primary high voltage series circuit and low voltage secondary circuit. The primary of all transformers are connected in series and fed by constant current regulator. Secondary feeds the individual Airport Runway light.
Isolating Transformer are used to maintain continuity of high voltage primary circuit in case one or more lamps are not in working order and to maintain the supply of 20 Amps. From the 6.6 amps. Series circuit or vice – versa alternatively to supply 6.6 Amps. From 8.3 amps . in the series circuit.
