How can we calculate the rating of capacitor bank to be
connected for a particular load(ex.100kw)to improve the
power factor from 0.8 to 0.9?
Answer Posted / suneetha
The rating of capacitor bank is in kvar.Kvar rating can be
found out by power traingle.
active power=100kw
let the angles corresponding to power factors .8 and .9 be
A1 and A2 respectively
then reactive power required to improve the power factor
=100sin(A1)-100sin(A2)
