GATE Electrical Engineering (EE) 2016 Shift 2 Solved Paper

Two identical unloaded generators are connected in parallel as shown in the figure. Both the generators are having positive, negative and zero sequence impedances of $\mathit{j}0.4\mathit{p}.\mathit{u}.,\mathit{j}0.3\mathit{p}.\mathit{u}.\mathit{a}\mathit{n}\mathit{d}\mathit{j}0.15\mathit{p}.\mathit{u}.$, respectively. If the pre-fault voltage is $1\mathit{p}.\mathit{u}.$, for a line-to-ground (L-G) fault at the terminals of the generators, the fault current, in p.u., is ___________.
