Answer Posted / arvind
yes there is an answer fir that, the answer is
KVAR=KW(inv(tan(PF2)-(inv(tan(PF1)))
where tana is desired power factor and tanb is your current
pf.
now to calaulate your a and b parameter we use this formula
power factor =cosa and power factor=cosb
i.e., inv(cos)=power factor
put this in above equation uyou will get your KVAR RATING
but you should the KW of the load.
