A New Method for Stator Ground Fault Protection with Voltage Injection on Large Hydro Generators Grounded by Arc Suppression Coils
For stator ground fault protection of large hydro-generators grounded with arc suppression coil at neutral point, the conventional method is to inject 20 Hz signal from the instrument coil attached to the arc suppression coil. In order to improve the effect of the protection and to overcome the diff...
