Yes both are same. They are used to measure the voltage in
the electric circuits. Their main role is to condition
(step down) the voltage to be measured to levels suitable
for the measuring instrument.

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
