Fault recorder is a data device that can accurately record accidents. It mainly refers to the whole process changes of system current, voltage and its derivatives, such as active power, reactive power and system frequency, caused by system oscillation, short-circuit fault, voltage collapse and other large disturbances. Only when the power line fails and affects the power transmission, the fault recorder can monitor it, record the fault type, and then analyze the fault, so as to deal with the fault quickly, which can greatly improve the safety performance of the power line and reduce the occurrence of dangerous accidents.

When there is a power line fault, the fault recording can respond quickly, and take corresponding measures for the fault, and then deal with it. Preventing this type of accident from happening again in the future can greatly reduce economic losses and bring convenience to staff.

The larger the system is, the more complex the accidents will be. In case of accidents on site, the operators are often busy with accident handling, incomplete records, reversed order of advantages, and the complexity of fault conditions (including fault continuity, conversion, fault plus shock, multiple fault continuity, conversion, fault home shock and overlapping of multiple faults), The protection device may act incorrectly (including misoperation, misoperation, abnormal action signal, etc.), resulting in the untrue situation reflected on the site. After the fault recorder is installed, the fault recorder graphic analysis shall be carried out, and the accident shall be accurate and timely. According to the analysis results, the real cause of the accident can be found out and corresponding countermeasures can be formulated.
