Question
2 star connected induction motor are fed by 4160 V, line to line, 3-phase 60 Hz
motor control 20 ft away. Motor A drives a 600 HP compressor. The efficiency of
the motor is 90 %, and its power factor is 0.5. Instruments of motor B indicate
1730 kW, 277 Amps.
i.) Determine the capacity in microfarads of a wye connected
capacitor bank that is required to correct the power factor of the load to 0.966
ii.) If a synchronous motor is installed in place of motor B and used instead of
the capacitor bank to achieve tha same overall power factor (0.966), what must be the power factor?
