| Abstract: |
| The injecting source-based stator grounding protection is widely used for large generation units， especially hydroelectric generators. It，combined with the fundamental zero-sequence voltage and third harmonic voltage protection，forms two sets of 100 % stator grounding protection with different principles. Its field test and setting scheme for a power station is summarized with its protective principle. Test data and results verify its accuracy. Some issues occurred during field test are analyzed and suggestions are given. |
