Hi,,
Just I want ask, if the power factor decrease what happen
in voltage regulation?
Thanks..
Answer Posted / ghanshyam singh
due to decrease in power factor, the value of line current
increases.
more line current means more voltage drop (i.e. voltage
regulation), where voltage drop is V=IR.

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?
Is there any problem about which the drive (inverter) doesn't show/display the alarm and/or fault but instead of this , it doesn't work ? I want to know that could there be any kind of problem in the drive when the drive doesn't display the alarm and/or fault ?
