4. Three-Phase AC Power The input power to a 3-phase AC motor was measured as P = 5kW (the true or active power). If the voltage and current to the motor

are 400Volts and 8.6Amp, respectively, calculate: A. the Power Factor of the system, pf B. Reactive Power (Q) in kVAR and C. Apparent Power (S) in kVA. D. the motor efficiency, if the motor output power is 7.5Hp Star & Delta Three-Phase Connections Star connection V 13- Vp Delta connection: Iv [5pts] [5pts] [5pts] [5pts] 13 p Vp
