In a power system network, pre-fault voltages at a busbar are given as
Va = 1 + j0, Vb = -0.45 – j0.8, Vc = -0.43 + j0.6
The positive, negative and zero sequence impedances with respect to busbar are given as
Z1 = Z2 = j0.3 pu, Z0 = j0.5 pu.
For a three phase to ground fault at the terminals of bus-bar, the magnitude of ground current will be ______ (in pu)Enter numerical value using the virtual keypad. Round off where necessary.
