The load on a single-phase three-wire system in a home is generally not balanced. For the system shown in Figure P7.18, let V₁1 11520 Vrms and $2 = 11520 V Determine: V rms. a. The total average power delivered to the connected loads: ZL1, ZL2, and ZL3. b. The total average power lost in the lines: Zg1, Zg2, and Zn. c. The average power supplied by each source. VS2 Zg1=0.192 Zn=2 Ω ww Zg2=0.192 Figure P7.18 ZL1 = 60 92 ZL2 = 80 92 ZL320 92 A large consumer of electricity requires 10 kW of power at 230 Vrms at a pf angle of л/3 rad lagging. The transmission line between the electric utility and the consumer has a resistance of 0.1 2. If the consumer can increase the pf from 0.5 to 0.9 lagging, determine the change in transmission line losses and load current.
