Examples 12.6,12.7 & PP 12.6 &12.7. Power in a Balanced Three-Phase System
Refer to the circuit in Fig. 12.13 (in Example 12.2). Determines the total average power, reactive power, and complex power at the source and at the load.
For the Y-Y circuit in Practice Prob. 12.2, calculate the complex power at the source and at the load.
A three-phase motor can be regarded as a balanced Y-load. A three-phase motor draws 5.6 kW when the line voltage is 220 V and the line current is 18.2 A. Determines the power factor of the motor.
Calculate the line current required for a 30-kW three-phase motor having a power factor of 0.85 lagging if it is connected to a balanced source with a line voltage of 550 V.
