Answer / manish panchal

Actually it depends on the motor's actual pf and the load with which motor is connected, so we have to connect capacitor with individual motor according to its pf.

Answer / kesavan.03

Normally, Induction motor current lags the voltage (lagging power factor), to improve the system power factor, we have to add the capacitors in parallel with the load end. Somewhat we can improve the PF to some extend value.
