Businessman Lance Smile own two large malls in Basilan Island. Both malls are connected in parallel and operating at a voltage of 13.2 kVms. The local utility supplied power to the malls through a feeder line with impedance equal to 1+j2.5 ohms. Mall 1 is consuming 400 kW at 0.75 pf lagging while Mall 2 is consuming 300 KVAR at 0.80 pf lagging. Determine the following: a) The local utility's sending-end (source) voltage. b) The total real and reactive power of the system. c) The overall pf of the system.
