value of the short-circuit current in one phase of the fault, which
is supplied by the generator and by the motor.
b)If the switch S3 of the transmitting
terminal of the faulty circuit operates at t=0,3(sec) and, assuming
that the other switches do not operate, determine the symmetrical
short-circuit current that makes it opérate
c)If S1 operates at t=10 sec.
Determine the symmetric current that interrupts, consider that S2
and S4 do not operate and that the generator recovered after S3
operated.
