A balanced three-phase delta-connected load is connected to a balanced three-phase delta-connected source via a transmission line. The line-line voltage for the source is 100∟0° V/phase and the impedance of load is (27 + j18) Ω/phase. The transmission line has an impedance of (1 + j4) Ω/line.
a) Draw the complete schematic of the power system showing the location of wattmeters. (Two-Wattmeter system is considered for this problem). Phase “a” could be considered as a reference phase.
b) What must be the readings on the two wattmeters?
c) What is the total power supplied to the load.
