1. The following sequence voltages were recorded on an unbalanced fault:

Given that the positive sequence fault current is j1, calculate the sequence impedances. Assume E = 1.

2. The positive sequence current for a double line-to-ground fault in a system is -j1 P.u., and the corresponding negative sequence current is j0.333 p.u. Given that the positive sequence impedance is 0.8 P.u., find the negative and zero sequence impedances.
