Does anyone have an idea of what to do for this question. Any help or guidance would be really appreciated.
A generator is subjected to a sustained fault with phases b and c short circuited together and to neutral.Show that the zero sequence impedance may be determined from the following relation: Z0=Ea/In where Ea is the voltage from the unfaulted conductor to neutral and In is the neutral current, i.e., the sum of the currents Ib and Ic.
