A power system has the following sequence network Thévenin equivalent reactances at the faulted bus: X0 = 0.1 p.u. X1 = 0.2 p.u. X2 = 0.15 p.u. Prefault voltage at the bus is 1.0 per unit. Find the fault currents for the four canonical fault types (3ϕ, SLG, LL, DLG) if the faults are bolted, and again for the case of ZF = j0.1 p.u.
