Unformatted text preview: P ave = 40 kW operating at a power factor of 0.7 lagging to boost it to a power factor of 0.9 lagging. The voltage across the parallel motor-capacitor combination is 230 0 V rms . The power relationships are shown in panel (a) below. If the frequency of operation is 120 = , compute the proper value of the capacitance, C (in mF). (a) (b)...
