Abstract :
Third harmonic, 100% stator ground fault protection schemes are becoming economically viable for small and mid size generators used in cogeneration applications. Practical considerations must be observed in order that such schemes are successfully applied for different machines. This paper introduces an experience with the applications of 3rd harmonic schemes in cogeneration applications and depicts their advantages and limitations. For a 50 MVA generator, actual measurements of produced third harmonics are portrayed and analyzed. In light of the experience and analysis, applications of certain third harmonic scheme configurations are contemplated
