1. A three-phase transmission link is rated 100 kVA at 2300 V. When operating at rated load, the total resistive and reactive voltage drops in the link are, respectively, 2.4 and 3.6 % of the rated voltage. Determine the input power and power factor when the link delivers 60 kW at 0.8 PF lagging at 2300 V.
2. A 60-hp, three-phase, 440-V induction motor operates at 0.8 PF lagging.
a) Find the active, reactive, and apparent power consumed per phase.
b) Suppose the motor is supplied from a 440-V source through a feeder whose impedance is 0.5 + j0.3 ohm per phase.
