Step 1
The line voltage is given as 208V. For a balanced three-phase system, the phase voltage is equal to the line voltage divided by the square root of 3. So, the phase voltage is 208V/√3 = 120V. The impedance per phase is given as Zy = 8 + j6. The magnitude of this Show more…

The total power measured in a three-phase system feeding a balanced wye-connected load is $12 \mathrm{kW}$ at a power factor of 0.6 leading. If the line voltage is $208 \mathrm{V}$, calculate the line current $I_{L}$ and the load impedance $\mathbf{Z}_{Y}$
The two-wattmeter method is used in measuring power taken by a balanced delta connected load. The wattmeters read 1500 W and 500 W, respectively. If the line voltage is 120 V, determine the magnitude of the impedance per phase.
