| Abstract: |
| The sensibility laws of the differential protection for SF125 96/15600 hydrogenerator with the internal interphase short circuit faults are investigated,including the effects of the turns ratio,the short circuit position and electric arc resistance,etc.The results are useful to relay protection analysis. |
| Key words: generator,differential Protection,sensibility |
