power factor is cosine of the the angle between voltage and current or the ratio of real power to reactive power. for an ideal operation power factor is unity. but in practical operation it is less than unity. if current leads the voltage power factor becomes leading and if current lags power factor becomes lagging in nature.
## lagging power factor can be improved by injecting the capacitive reactive vars in to the system. and different methods are
1.by connecting shunt capacitor
2.by connecting series capacitor
3.synchronus condenser
##leading power factor can be improved by injecting the inductive reactive vars in to the system. different methods are
1.shunt inductor
2.synchronus condencer
