A 396-Vrms, 60-Hz supply serves a load that is 17 kW (resistive), 5 kVAR (capacitive), and 14 kVAR (inductive). What is the capacitance required to improve the power factor to unity? Write your answer in micro-Farad.
A three phase 390 volt (line voltage) distribution system feeds power to a household load. Each phase of the system (distribution line) has an impedance consisting of a resistance (0.602) and a reactance (0.40) (inductive). The system is connected to three-phase load with an impedance of j +62 in a delta connection. What is the active, reactive and apparent power of the load (notice that distribution line impedance is not part of the load)?
