Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Currently, as being constantly progressive for society has penetrated into the Fang Fang of people's lives with economic rapid development, electric power
Face face, at indispensable pith in for people's lives.Electric quantity metering device is used to user the case where using electric power
Carry out quantitative statistics.But in actual use, on the one hand due to being influenced by natural causes such as direct lightning strike and inductive lightnings,
Voltage transformer is easy to happen operation exception or failure in electric power metering device, causes the metering fault of electric power metering device；Separately
On the one hand since transmission line natural aging, high-voltage insurance fusing, the metering of phase shortage decompression and artificial wiring error etc. will also result in
The metering fault of electric power metering device.When electric power metering device metering fault occurs, the loss of electric power data is caused, it can be to confession
Electricity side and electricity consumption side cause unnecessary loss and trouble, are based on this, a kind of adaptive metering event provided in an embodiment of the present invention
Barrier load records equipment and system, can read and store in time the electric power number that electric power metering device measures in voltage secondary circuit
According to raising remedies the reliability of electric power data back after electric power metering device metering fault occurs.
For convenient for understanding the present embodiment, first to a kind of adaptive metering fault disclosed in the embodiment of the present invention
Load records equipment and describes in detail, as shown in Figure 1, it may include: that detection is single that adaptive metering fault load, which records equipment,
