An unbalanced delta-connected load is connected across the lines of a 4-wire balanced three-phase supply with neutral connection. Two wattmeter W1, W2 are connected in lines 1 and 3 with the common potential connection in the neutral wire. These wattmeters read 1796.5 and 3000 watts, respectively. The current in lines 1 and 3 is 20 A. If the common potential connection is transferred to line 2, what will be the reading of the two wattmeters? The system voltage per phase is 208 V. Assume a phase sequence of 1-2-3 with V1n as reference.
