The fault recorder can not only save the fault recording data in the floppy disk for analysis by special analysis software, but also transmit the recorded fault recording data to the dispatching department through the communication interface of the fault recorder, so as to provide timely basis for the dispatching department to analyze and deal with the accident.

      The fault recorder plays an important role in the whole power system. Just like the traditional electronic products, the fault recorder not only needs to pay attention to the method, but also needs to maintain the fault recorder device. The maintenance of the fault recorder is not complicated. There are fixed inspection and supervision staff in the power plant or station, and they will be fixed in Check once a day or once every two days. In daily inspection, it is necessary to pay attention to whether the front panel indicator light of fault recorder is normal.

When the fault recorder is in normal state, the "running" light is flashing and the "fault" light is off. When the device starts wave recording, the "wave recording" light is on, and after the wave recording is restored, the "wave recording" light is off. It is necessary to pay attention to the operation state of fault recorder during inspection. Secondly, it is suggested to check whether the printing paper is used up once a month and make up in time.

In order to ensure the stable and reliable operation of the fault recorder, daily maintenance is the key. Only by carefully implementing the inspection system can we find and deal with the problems and hidden dangers in the operation.
