The mechanical power input to the generator and the voltage magnitude $E$ are constant. If one line is tripped at time $t_{1}$ by opening the circuit breakers at the two ends (although there is no fault), then it is seen that the generator undergoes a stable transient. Which one of the following waveforms of the rotor angle $\delta$ shows the transient correctly?
