Q: Short circuit and system for generating what harm?

A: The short circuit on the generator hazards:

(1) End of the stator winding is greatly effect the electromagnetic force, has the potential to bar the outer insulation breakdown;

(2) the role of the rotor shaft by a large magnetic moment;

(3) causes the stator and rotor windings fever;

Impact on the power system short-circuit:

(1) may cause damage to electrical equipment.

(2) may be due to low voltage operation and destabilize the system.
