High-quality series isolating transformer designed to stringent industry standards and manufactured in compliance with FAA AC150/5345-47 and IEC 61823 are readily available.
The isolating transformers product range includes a number of transformers and accessories:
Like all ATG Airports products, this range is built to withstand extreme weather conditions as might be experienced on any airfield, with guaranteed durability. The transformers are designed for continuous operation, at full load, short circuit or open circuit, under ambient temperatures ranging from -55 °C to + 65°C.
The transformers are manufactured to relevant FAA standards including specifications L830 and L831 (AC 150/5345-47). A choice of different power ratings and current capacities allow for installation on circuits with varied load requirements, with full details available in the downloadable product data-sheet.
Isolating airfield transformers are primarily used to ensure safety in the continuous, exposed operation of AGL circuits. They can do this in a number of ways:
Voltage regulation protects valuable lighting equipment against power inconsistencies, including over-current conditions.
Grounding reduces the risk posed by residual currents and short-circuit leaks, preventing accidental shocks to personnel.
There are many more reasons why isolating airfield lighting transformers are used, but in general, the protection of lighting equipment and personnel is at the heart of the design and operation of these important units.
ATG Airports offers a complete design and build service, with airfield transformers manufactured to aviation industry standards including FAA L830 and L831.
We can design your entire AGL circuit, as well as carry out any required AGL civil works for a full and correct installation. Our experienced team can plan and install your AGL equipment for safe and reliable operation, giving you maximum longevity with minimised maintenance.
Once your AGL circuit is running, we provide facilities management services and round-the-clock maintenance availability. This means that in the event of an incident affecting your isolating transformers, constant current regulator or runway/taxiway lighting, we can restore your airfield to full operation as quickly as possible.
We understand the pressures of maintaining a fully accessible airfield 24/7 with zero downtime. By choosing reliable, high-quality airfield isolating transformers from ATG Airports, you give your AGL circuit everything it needs to function correctly, without unplanned outages.
To find out more about our isolating transformers, or to ask us anything about the design, build, installation and maintenance of AGL circuits and cables, contact ATG Airports today and our team will be happy to help.
An airfield lighting isolating transformer provides electrical power to an AGL light while isolating it from the CCR supply.
The power rating of your isolating transformer depends on the total secondary voltage required. You can find the ratings in watts of all of ATG’s isolating transformers in our PDF data sheets. If you need any further help deciding which transformer you need for your circuit, contact our team and we will be happy to advise you.
Regular inspections help to confirm the isolating transformers are still in good physical condition, as well as to verify the primary, secondary and earth connections are all still secure. Planned maintenance should be carried out at least once every six months, with more frequent inspections where necessary or desirable.
Where a suitable isolating transformer is installed and maintained correctly, it should function for many thousands of hours without incident.
