Hello everyone
How to pass from a 3 phase 120/208V 50Hz to 120/208V 60Hz ?
what transformer can do that ?

dthimot; post some more info the load, is it a motor?
and if so look into a Variable frequency Drive or VFD.
If its a resistive heating load you need not worry about frequency.

Not just resistance heating. Frequency conversion is not necessary for many applications.
If there are pulleys and belts, or sprockets and chains, the mechanical drive ratio can be adjusted to accommodate the different motor speed.
Many machines can simply be operated at the higher or lower speed if the voltage is appropriate. (near-constant volts-per-Hertz ratio)

But are you sure you have 120/208V 50Hz? That's a very unusual service configuration.

My thoughts exactly. Haiti is 60Hz so maybe the poster is trying to use a 50Hz bit of kit for his application. Maybe we will find out in due course.
