Abstract: Taking GE G60 generator stator overload protection and domestic large turbine generator for example, this paper analyzed the cooperated situation of GE G60 generator stator overload protection eleven curves with the inverse time characteristics and the stator winding overload capacity. Considering not only giving full play to the limit load of generator stator winding capability, but also maintaining a reasonable difference cooperation relations, the IAC Extreme Inverse curve and the generator stator winding overload capability have the best matching relation.
Key words: stator; overload protection; inverse time; cooperate
