| Abstract: | The main reason that causes the difficulty to locate single-phase grounded fault lines in non-effectively grounded power system was analyzed,and by simulating the transient-state and steady-state character of the fault wave,the principle based on fault record analysis was put forward.Then the design of a new ground-fault protection device based on ARM and DSP was introduced. |
