A synchronous motor capable of operating with a leading power factor draws 15 kW from a distribution transformer while driving an air compressor. The remainder of the load on the transformer is 80 kW at 0.85 lagging power factor. (a) How many kilovars of capacitive reactive power must the synchronous motor produce to raise the overall power factor to 0.96 lagging? (b) What is the reactive factor of the synchronous motor operating in this manner?
