The selection of fault recording wave startup methods can ensure that the fault recorder can reliably start in the event of any type of system failure. Generally, the following startup methods are included: negative sequence voltage, low voltage, overcurrent, zero sequence current, zero sequence voltage.

The fault recording device is used to automatically record electrical and non-electrical quantities as well as switching quantities in the power system. By recording and monitoring the analog and event quantities in the system, it generates fault waveforms for faults and anomalies that occur in the system, stores them, and sends them to a remote master station. Through the processing of analysis software, the waveforms are analyzed and calculated, allowing for accurate judgment of the nature of the fault, the distance to the fault occurrence point, and the severity of the fault.
The fault waveform analysis software has a user-friendly interface and powerful functions. Compared with similar software products, it has advantages such as stable operation, ease of use, and flexible operation. The graphical analysis software includes several parts such as waveform analysis, harmonic analysis, vector analysis, list analysis, impedance trajectory analysis, and distance measurement analysis.
