Description

Technical field

[0001] The invention belongs to electric energy metering fault detection in electric power systems, in particular to an intelligent networked electric energy metering fault detection and recording method. Background technique

[0002] In the prior art, the fault detection and recording method of electric energy metering generally only detects voltage or current amplitude and phase. In terms of detection methods, it is usually judged whether the electric energy metering device loses voltage according to the magnitude of the grid voltage; or judges whether the electric energy metering device loses current according to the magnitude of the grid current amplitude; or judges the electric energy metering according to the phase relationship between voltage and current. Whether the device is connected incorrectly; according to the judgment result, record the failure time of the electric energy metering device. However, it is impossible to judge and record the faults...
