F-6). A 3-phase power capacitor rated at 12.47kV and 1200 kVAR has been proposed for power factor correction in a 12kV 3-phase system. The reactive power (KVAR) that will be provided by the capacitor is most nearly: a. 1,295.84 KVAR b. 1,200 KVAR C. 1,111.24 kVAR d. 1,247 KVAR Solution: The VARs vary as the square of the applied voltage. KVAR = (12kV/12,47kV)" (1200KVAR) = 1,111.24 KVAR = The correct answer is c.
