For the staff in the power industry, the fault recorder is no stranger to us. The function point of the fault recording device is to provide an important basis for correctly analyzing the cause of the accident and dealing with the accident in time.

The fault recorder is used to record the voltage and current data and the action sequence of relevant protection and safety automatic devices in case of system failure or abnormal working conditions in the store. When a fault occurs, it is necessary to analyze what kind of fault protection device action has taken place in the power system, whether the behavior is correct, whether the secondary circuit wiring is correct, whether the CT and Pt polarity are correct, and so on.

According to the data or waveform recorded by the fault recording device, the primary current and voltage values can be calculated, so as to calculate the location of the fault point, which greatly reduces the scope of line patrol, saves time and effort, speeds up the process of handling accidents, and plays an important role in quickly restoring power supply. Therefore, when an accident occurs in the power system, there must be a set of fault recording device that can truly record all kinds of analog and switching states of the system before and after the fault occurs.
