What is the rating of your capacitor bank at your company.
Answer Posted / vijay kumawat
if your power factor is suppose 0.75, and you have to improve your pf to unity then find the inverse cos of 0.75, then find the tan(cos^-1(0.75)).
then find the value you have to improve the pf suppose you have to maintain to unity then, cos^-1(1) then find the tan (cos^-1(1)).
the find the [tan (cos^-1(1)) - tan(cos^-1(0.75))] * kw of motor
