Question:

Consider Figures 8.13 and 8.14 of the text with reference to a Y-connected synchronous generator (grounded through a neutral impedance \(Z_{n}\) ) operating at no load. For a line-to-ground fault occurring on phase \(a\) of the generator, list the constraints on the currents and voltages in the phase domain, transform those into the sequence domain, and then obtain a sequence-network representation. Also, find the expression for the fault current in phase \(a\).
