  • ENA 12.7(1)(U/H) Power in a Balanced Three-Phase System
    Example 12.6, 12.7. Practice Problem 12.6 & 12.7.
    Refer to the circuit in Fig. 12.13 (in Example 12.2). Determine 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 threephase motor draws 5.6 kW when the line voltage is 220 V and the line
    current is 18.2 A. Determine the power factor of the motor
