Answer / joel q.

You must add a capacitor bank. you can determine the size
of the capacitor to be added using the following formula.

KVAR = KW*Tan((arccos0.6) -(Arccos0.9))

Answer / raju

to improve powerfactor only capacitor banks should be used
but not inductor as capacitor having leading pf which wil
reduces reactive power and improves pf

Answer / kaushik

if we are talking for 0.6 pf laging to 1 pf then we require
a capacitor bank.
the rating of the bank will be=v*i*sin(angle) in vars
angle=cosinverse(0.6).
if we are talking for 0.6 pf leading to 1 pf then we require
a inductor bank.
the rating of the bank will be=v*i*sin(angle) in vars
angle=cosinverse(0.6).
v=supply line voltage.
i=line current.

Answer / amrish sharma

just calculate total load of plant,,, then use capacitor 30
percent rating of total load,,, example if you have hunderd
ampere load then use 30Kvar capacitor,,,

Answer / jothi

If power factor must be improved from lower value to higher
value then capacitor or inductor banks must be added....

Answer / saravanakumar

If you want improve your power factor, you should provide a
capacitor bank.The rating of the bank is 1/3 rd of the
transformer ratings.
