| Abstract: |
| In site operation,stator grounding protection often gives false signal,therefore some units raise the setting value greatly for the dependability of protection. It is pointed out that the proper adjustment of arc suppression coil and coordination of system parameters may reduce the setting values and improve the running reliability. |
| Key words: generator,stator grounding,arc suppression coil,setting value |
