발전기 회전자의 층간단락에 대한 특성 해석

Shorted-turns can have significant effects on a generator and Its performance. Shorted-turn sensor for synchronous generator's field winding have been developed One of effective method detecting inter-turn short circuits on round rotor winding is a method using sensor detecting But the method needs duplicate design of sensor for characteristic change according to types and forms of generator Thus sensing skill without sensor depend on change of electric property in generator For the reason, this paper presents shorted-turns phenomenon and the characteristic analysis of shorted-turns 10 synchronous generator by using 2-D finite element method(FEM)
