2. A balanced star load with impedances of 6∟45o ohms is connected to a threephase, four-wire, 208 volt, ABC system. Find the line currents, the neutral
current, the power per phase and the total power (S, P, Q).
3. A 460- volt three-phase source supplies a balanced load of 200 kW at a lagging
power factor of 0.707, and the two wattmeters are properly connected to
measure the total power. Calculate a) line currents, b) reading of the wattmeters.
4. In a balanced 230-volt three-phase circuit two wattmeters are connected to
indicate power. If the readings are 8140 W and -2980 W, calculate the power
factor and the line currents
