GATE2016141
A $30 MVA$, $3$phase, $50 Hz$, $13.8 kV$, starconnected synchronous generator has positive, negative and zero sequence reactances, $15$%, $15$% and $5$% respectively. A reactance $(X_{n})$ is connected between the neutral of the generator and ground. A double ... $X_{n}$ (in p.u.) that will limit the positive sequence generator current to $4270$ A is ________.
