I am wondering, if a sychronous generator has a smaller posibility to be burnt (be destroyed permanently) from a short circuit, that has a dc generator with parallel wound or a seperately excited dc generator, and why?

Presuming that both devices had their excitation set to allow them to deliver rated power at rated voltage, a synchronous generator with separately excited field winding and a DC generator with separately excited field winding will both suffer from thermal overload of the armature winding in a sustained fault if the excitation is held constant. The thermal overload may permanently damage the winding depending on the duration of the overload. The DC generator may also suffer damage to the commutator and brushes from the elevated armature current.

The basic difference between the two can be understood from their names, DC generator gives Direct Current(DC) and Synchronous Generator gives Alternating Current(AC).
