| 摘要: |
| 对某水轮发电机作内中相间和匝间的短路计算，在发电机弧立运行，空载额定电压且不计励磁调节器作用的工况下，求最小工频分量短路电流，相应的灵敏系数也是实际最低值。 |

| Abstract: |
| The interphase and interturn short circuits of a hydrogenerator are calculated. The fundamental 50 Hz currents of steady state short circuit are obtained as the generator is operated under no load,rated voltage and without the excitation regulator.The relative sensitivity coefficient is really the smallest value.The analysis indicates that the high sensitivity single transverse differential,non complete and complete longitudinal differential protections constitute multiple protection functions. |
