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 (0.60) 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)? Give the answers to two decimal places. a) Absolute value of current feeded by the voltage source. I = 3.62 A Your last answer was interpreted as follows: 3.62 b) Active power P = c) Reactive power Q d) Apparent power S (absolute value) = = kVA kW kV Ar 4

Question
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)? Give the answers to two decimal places. a) Absolute value of current feeded by the voltage source. I = 3.62 A Your last answer was interpreted as follows: 3.62 b) Active power P = c) Reactive power Q = d) Apparent power S (absolute value) kVA = kW kV Ar 4
