how much does an electrical motor of 380V AND 150HP losses of his effeciency after turning on
no
Yes. It will make your motor a little faster though, so it depends on what you are powering with this motor. IE Can the piece of eguipment be ran faster?
In most applications 200v is easier to get for a supply voltage than 380v.
380v 60 hz is suitable for running 180kw induction motor

There are no three phase 120 volt systems.
It will not work at all.

Yes it can run because motors have 10% voltage variation tolerance so it can operate between 380v - 440v band.
Not advisable, the voltage differential is too great.
