Question:

The average power delivered to a balanced Y-connected load is \(20 \mathrm{~kW}\) at \(60 \mathrm{~Hz}\) at a lagging power factor of 0.8 . The line voltage at the load is \(V_{\mathrm{L}}=480 \mathrm{~V}(\mathrm{rms})\).

(a) Find the phase impedance \(Z_{Y}\) of the load.

(b) Change the load so that the power factor is leading by the same power factor.
