Determine the line currents in a star connected load supplied from a symmetrical 3-phase, 3 wire 400V system using mesh current analysis. The branch impedance of the load are Za = (7 + j4.04)№, Zß = (8.66 + j8.66)№ and Zc = (4.04 + j7)№. Take the phase sequence as ABC. A symmetrical RYB, 400V, 50Hz, three phase supply is connected to unbalanced delta connected load. The load impedances are 150 N between R & Y, (50- j50) ≤ between Y & B, (30+j70) № between B & R. Draw the circuit diagram for two wattmeter method for measurement of power and find out the readings of two wattmeters.

The undesired states should be depicted to be transiting to any of the desired states.Choose the 000 state for this purpose. It is important to include the undesired states to ensure that,if the counter accidentally gets into any of these undesired states owing to noise or power-up, thecounter will go to a desired state to resume the correct sequence on application of the next clockpulse.
