If the load is 10Kw and power factor has to improve from 0.5
to 0.8,how can we select the capacitor rating
accordingly.Illustrate by showing formula?
Answer Posted / prakash g.r.
Calculation of Required Kvar
Initial or Present Power Factor =Qi,
Required Power Factor = Qd
KVAr= KW(TANQi-TANQd)
Qi=COS-1PFi = Initial Power Factor Angle
Qd=COS-1PFd = Final Power Factor Angle
