15 Years of Experience with 100% Generator Stator Ground Fault Protection - What Works, What Doesn't and Why

This paper discusses the application of three different 100% stator ground fault protection schemes. Two third-harmonic methods and a low frequency-injection method are discussed. Third-harmonic schemes have been widely applied on generators within the U.S. to provide stator ground fault protection over the entire stator winding. More
