      With the increasing scale of power grid, a comprehensive analysis system of power grid fault information is needed, which can accurately diagnose fault components, analyze post accident data, and evaluate protection action behavior. This is the fault recording device. It plays a very important role in the safe and reliable operation of power system.

      All kinds of fault information of power system are recorded in time by fault recorder. The startup of fault recorder depends on the electrical quantity with obvious fault characteristics, such as voltage, current, frequency and switching value.

      35kV and above substations and corresponding lines shall be equipped with fault wave recording devices, which can be started quickly in case of power system fault and may be started reliably in the process of system vibration, record relevant electrical parameters in the system and analyze the waveform.
