    A 35 kW induction motor has pf 0.9 and efficiency 0.9 at full load, pf 0.6 and efficiency 0.7 at half load. At no load, the current is 25% of full load current and pf 0.1. Capacitors are supplied to make the line pf 0.8 at half load. With these capacitors in circuit, find the line pf at (i) full load (ii) no load.

    A 340 kW, 50Hz, 3 phase star connected induction motor has full load efficiency of 85% and p.f of 0.8 lagging. It is desired to improve the power factor to 0.96 lagging by using bank of three capacitors. Calculate: (i) The kVAR rating of the capacitor bank. (ii) The capacitance of each limbs of the condenser bank connected in delta. (iii) The capacitance of each capacitor, if each one of the limb of the delta-connected condenser bank is formed by using 6 similar 3300v capacitors.
