Repeat Example 12.13 for the network in Fig. 12.24 (see Practice Prob. 12.9)
Â
Practice Prob. 12.9
The unbalanced -load of Fig. 12.24 is supplied by balanced voltages of 200 V in the positive sequence. Find the line currents. Take Vab as reference.

Example 12.13
Three wattmeters W1, W2, and W3 are connected, respectively, to phases a, b, and c to measure the total power absorbed by the unbalanced wyeconnected load in Example 12.9 (see Fig. 12.23). (a) Predict thewattmeter
readings. (b) Find the total power absorbed.
