1) A 60 Hz three-phase induction motor draws 25kVA at 0.8 lagging power factor from a 400-VLL source. It is desired to improve the power factor to 0.92 by connecting a capacitor bank in parallel with the motor. A) Specify the required kVA (kVAr) rating of the capacitor bank. B) If the capacitor bank is ?-connected, find the value of the capacitors. C) Determine the line current (rms value), at the source, before and after the addition of the capacitor bank. D) For a per-phase equivalent circuit, show the phasor diagram of the motor current, capacitor current, source current and source voltage (reference phasor).
