Fault recorder screen is an automatic equipment to monitor the operation of power system. When the system is in normal operation, the wave recorder does not start the wave recording device. When the system fails, the wave recorder is started quickly by the starting device to record the electrical quantity reflecting the system fault at the installation place of the fault device.

When there is an electrical fault, our first reaction is whether the protection works correctly. However, to comprehensively analyze the fault type and fault duration, we need to look at the record file of the fault recorder. Only by analyzing the waveform recorded in the file can we get the answer quickly.

      Through the analysis of the fault recorder, we can get the type, phase and evolution of the fault, the action of relay protection, the working condition and fault location of circuit breaker in case of fault, the situation and data of unit cleaning and power grid operation. In order to deal with the accident quickly, correctly evaluate the working state of various protection devices, circuit breakers and automatic devices It is beneficial to ensure safe operation.

Information that can be obtained according to fault oscillogram

1. Electrical components and fault types

2. Protection action time and fault clearing time

3. Fault current and fault voltage

4. Reclosing time and whether reclosing is successful

5. Detailed protection action

6. Complete auxiliary functions (ranging, impedance trace, phasor and harmonic analysis, etc.)

The fault recorder analysis software extracts the characteristic information of the fault process according to the changes of the electrical parameters in the transient process of the system provided by the recorded data, and carries out comprehensive and accurate fault analysis under the theoretical support of the existing fault analysis principle. Automatic fault analysis can not only greatly improve the automation level of the whole power grid, but also strengthen the ability of fault analysis and processing.
