4 hor
4a. A 340 kW 50 Hz 3-phase star-connected induction motor has full load efficiency of 85% and power factor of 0.8 lagging. It is desired to improve the power factor to 0.96 lagging by using a bank of three capacitors. Calculate:
4 ai . The kVAR rating of the condenser bank
4aii. The capacitance of each limbs of the condenser bank connected in delta
4b. What are the other ways of power factor correction apart from the use of capacitor banks?
