If i have a 3 phase motor running in 440volts and drives the cetrifugal fan, then the voltage drops to 20 percent, what happened to running current does it increas or decrease.

Yes.
Well if you have the fan, measure the current.
Looks like homework.

A) Three phase = NOT DIY!
B) 440v(? - is the Europe) = NOT DIY!
C) Drops TO 20%? So the voltage drops to 88v?
D) Do your OWN homework!
