Application:
Isolating
transformers 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 transformers
are used to maintain continuity of high voltage primary circuit
incase 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 suppl 6.6 Amps. From 8.3Amps in the series circuit.
Specification:
- IS: In compliance with IS-12290-1987
- FAA: In
compliance with AC-150/5345-47.
- IAF: In compliance with CRI/Ale/
107 of 1989
