Generator as the most upstream part of the power system need to be installed to protect against damage. If the damage to the generator will affect the reliability of the system so that interfere with the operation of the electric power system, in addition to generator prices are also expensive. The damage of the generator may arise due to short-circuit on the stator winding, overload, overheating of windings and bearings, overvoltage and more speed ( loss of field ), Motoring, unbalance current on the stator, Out of step. This thesis will discuss safety for short circuit 1 phase to ground and 3 phase in stator winding (stator ground fault). For stator ground fault safety is used Zero-Rated Voltage Rele (59GN device), but because the 59GN release can not protect stator 100% winding it is necessary to coordinate with other releases so that the protection is more reliable.} }
