       Fault recorder is an important automatic device to improve the safe operation of power system. During the normal operation of the power system, the fault recorder does not start the wave recording. When the system fails or vibrates, the fault recorder quickly starts the wave recording to directly record the electrical quantity in the process of fault or oscillation.

        The importance of fault recording is not only reflected in this point, but also conducive to the staff on the project site to find the defects of relay protection and automatic devices, and to improve and perfect power equipment.

        For example, in the design of relay protection and automatic device wiring circuit installed on generator set and EHV line, although it has been carefully studied, there may still be unreasonable or thoughtless places. These problems can not be easily found in various simulation tests and even in operation, but in case of system accident, the device will refuse to operate or misoperate.

        If there is no fault recording, such problems are almost difficult to find and improve in time. As a result, similar misoperation or refusal accidents may occur repeatedly. With the fault recorder, the defects of the device can be found by using the recording data and analysis, which can be eliminated in time and the wiring of the device can be improved.

        This is also the benefit of installing fault recording device in the power system. A small equipment can improve the power system and save manpower and material resources to troubleshoot.
