QUESTION 2 A factory takes 200 kw at 1100 V from a three-phase source and the power factor is 0.707 lagging. A synchronous motor is installed which takes an additional 100 kW. What must be the kVA rating of this motor to raise the power factor of the system to 0.90 lagging. CHOICES ARE: a. 114 kVA b. 144 kVA c. 111 kVA d. 115 kVA

The full load losses in a 5,000-kVA three-phase 6,600-volt synchronous converter are 160 kW. Calculate the full-load current and the power factor. It is desired to correct the 2,400 kVA 0.65 lagging power factor load in a plant to unity by the installation of a synchronous converter. Calculate the kilovolt-ampere rating of the latter.
