13.4 Generator electrical fault
In case of a generator electrical fault, the generator breaker is opened and the alternator is de-excited (if
wired) during a certain time [E1265]. If the fault is still present after this time has elapsed, a hard shutdown
occurs. Otherwise GENSYS 2.0 will try to re-synchronize. Associated parameters are listed in the table
below.
