how we can calculate which capacity capacitor bank we have
to add for improve pf?
Answer Posted / z_hosen
More simply,
Let total power is 1500kw
assume
cos 1 =power factor before improvement =0.75
cos 2= poer factor after improvement =0.98
tan1=0.88
tan2=0.2
and
kvar 1= power*tan1=1500*0.88=1320kvar
kvar 2=power*tan2=1500*0.2=300kvar
now, required rating of capacitor bank =kvar1-kvar2
=1320-300
=1020kvar =1000kvar

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?
