Ya es bastante grave que se produzca una caída de hasta 200 kA en cualquier punto de campo, pero si esto ocurre cerca del generador, los efectos pueden ser devastadores: la corriente de fallo puede ser de tal magnitud que las fuerzas magnéticas inducidas por ella lleguen a doblar e incluso a destruir los sólidos ejes de acero.
Generator earthing and stator earth fault protection | EEP
Generating unit is a pretty complex system made up of the generator stator winding, its transformer and unit transformer (if present), the rotor with its field winding and excitation system, and the prime mover with its associated auxiliaries.

Induction motor startup and losses calculation | EEP
Induction motor startup and losses calculation If the rotor resistance is increased by some means, then the slip and speed at which maximum torque occurs can be shifted. For that purpose, external resistance can be introduced in the rotor circuit, which is done in the case of slip ring or wound rotor type motors.
Generator Protection ERPC
Generator Protection Introduction Size of individual generating unit 30 MW to 500/1000 MW Loss of even a single unit is a serious problem Consequence : Protection systems of such generators have also become more stringent Required to reduce the outage period to a minimum Achieved by rapid discriminative clearance of all fault
