I'm curious. For wind generators is it typical to incorporate a weak link on the shaft between the gearbox and the generator. This would be for the possibility of a stator winding fault. The EMF of a PMG will create hundreds of amperes of current, only limited by the impedance of the stator winindgs, possibly causing a fire hazard. The torque created by this fault current would shear the weak link.
Or, on the other hand, are these generators so reliable that my concern is not an issue at all?
thanks
