Do I need a special Transformer to put 240 VAC 3 phase into
it and and get 480 VAC 3 phase out of it to run a machine?
Or, do I just use an ordinary step down transformer and step
up the voltage? Thanks

Answer / joseph

The question is rather vague.

Since your machine is rated for 3 Phase, 480V, then just
use a three phase distribution transformer (11/.433 KV).

I have two AC generators, the first rated 2680KVA for 380V/4345A/pf:0.7 and the second rated 3461KVA for 5500V/363A/pf:0.8. I want to parallel the two generator to a bus. The second generator passes through a transformer to down the voltage to 380V and a part of its power goes to another bus so that it's only a part of the total power of the second generator taht goes to the considered bus. I have two Basler DECS100 AVR regulator. How can I make the synchronization ? What others equipments must have ?
