Buck-Boost Transformer

We are installing a 200 kVA fuel cell a building and have been advised that it will have problems if the voltage ever goes over 440V and we should provide a buck/boost transformer to step the voltage down by 8%.



Anyone have details of such a unit? Names of suppliers?

Re: Buck-Boost Transformer

Advised by who?

480v is the nominal voltage around here, so you would be LOW.

What does the EC and/or engineer say?

I checked his other posts. He's in Belgium, so their voltage would be 400Y/230V, therefore "over 440v" is over 110%.

Um.. wouldn't ABB or Siemens have stuff like that available in EU?
