| Abstract: | The fast detection circuit for fault electric signal based on instantaneous state limitation is analyzed and simulated. Various parpmeters in the course of dynamic variation are recorded by digital oscillograph. The results show that fast detection circuit may instantaneously detect the fault electric signal under dynamic state and the sampling time is rather short. |
