Abstract：
 The present invention belongs to the field of power system, including four portions of topping machine, background machine, power system synchroclock and printer, in which the topping machine includes steady-state voltage and current collecting unit, transient voltage and current collecting unit, high-frequency collecting unit and GPS (global navigational satellite timing and distance-measuring system) time synchronization unit which can be used for providing accurate time mark and interfaced with power system synchroclock. The background machine adopts industrial control computer for fault data analysis and processing, the power system synchroclock is used for providing accurate time information and the printer can be used for printing fault record and fault distance-reasuring result.
