How to set up two transformers to give me an output of 220 v ac and 160v ac from 380V ac?

How do i attach two transformers from an ac generator that outputs 380 to give me two seperate outputs of 160 v ac and 220 volts ac... details would help... im new at this...How to set up two transformers to give me an output of 220 v ac and 160v ac from 380V ac?Call upon Optimus Prime and Bumblebee.How to set up two transformers to give me an output of 220 v ac and 160v ac from 380V ac?Depends on requirements. In all cases make sure that VA requirements are known

If the 160 and 220 volts have to be isolated from each other then you will need either one transformer with 1 primary (380V) and 2 secondary windings (160V and 220V) or 2 transformers, 380 to 220 and 380 to 160V

If these do secondary voltages do not need to be isolated then you could use a 380 to 380 V transformer with a tap at the 220V point on the secondary. The tap can then be the common and you will have 160 one side and 220 the other side. (Note that phase relationship will be 180 degrees out)How to set up two transformers to give me an output of 220 v ac and 160v ac from 380V ac?You may be in over your head here.

220/380 is a standard multiphase system.

If you've got 380, 220 is very likely also available.

To get 160 from 380 you'd need an 8:19 ratio transformer.

Size does matter.

Any transformer must be sized for the load supplied.

So does type, and you don't give the size or the types of loads supplied.

If you're "new at this" get some direct guidance.How to set up two transformers to give me an output of 220 v ac and 160v ac from 380V ac?
Of course. This boat is real.
