In This case no other detail is given except the power
rating .
Therefore pf=( KW/KVA)
In order to get incentive and good power factor it is
required to maintain power factor above 0.95
So we take pf=0.95 and kw=(65*0.746)=48.49
Therefore KVA= 48.49/0.95 = 51.04
We know that KVAr= Squareroot( (KVA)^2-(KW)^2)
Therefore KVAr = sqrt(51.04^2-48.49^2)
=15.90 approx..
Capacitor required = 16KVAr.
