Noise Contribution in a transformer

[EddyPach]

Hi all. Can you please confirm what is approximately the noise level contribution in a pwoer transformer: i.e. what percentage is due to the tank, how much is due to the fans and how much due to the pumps in a FOA system.

Thaks,

These values are typically part of the factory tests. You should be able to get them from the manufacturer.
