GATE Electrical 2012 | Question: 34
A cylindrical rotor generator delivers $0.5$ pu power in the steady-state to an infinite bus through a transmission line of reactance $0.5$ pu. The generator no-load voltage is $1.5$ pu and the infinite bus voltage is $1$ pu. The inertia constant of ... degrees, for a three-phase dead short circuit fault at the generator terminal is $53.5$ $60.2$ $70.8$ $79.6$
