Three identical impedances (Z_{Delta}=30 / 30^{circ} Omega) are connected in (Delta) to a balanced three-phase (208-mathrm{V}) source

Question:

Three identical impedances \(Z_{\Delta}=30 / 30^{\circ} \Omega\) are connected in \(\Delta\) to a balanced three-phase \(208-\mathrm{V}\) source by three identical line conductors with impedance \(Z_{\mathrm{L}}=(0.8+j 0.6) \Omega\) per line.

(a) Calculate the line-to-line voltage at the load terminals.

(b) Repeat part (a) when a \(\Delta\)-connected capacitor bank with reactance \((-j 60) \Omega\) per phase is connected in parallel with the load.
