Answer Posted / dinesh lokhande
A simple formula will help to co-orelate power factor, KW
load, and Kvar (i.e reactive power) required.
kvar = KW (Tan Qi - Tan Qd) where,
Qi = Cos inverse pfi = Initial power factor angle
Qd = Cos inverse pfd = Final power factor angle
After calculating Kvar we can select no of capacitors
required by looking at capacitor catalog.
